<p class="wp-block-paragraph">At Controlled Air, we are always investing in the tools and technology that allow us to deliver better results for our commercial HVAC clients across Connecticut and Rhode Island. We recently outfitted our sheet metal shop with a suite of new equipment and the improvements in quality, efficiency, and craftsmanship are ones our customers will notice directly on every project.</p>



<h2 class="wp-block-heading"><strong>New Chop Saw — Precision Cutting for Complex Work</strong></h2>



<p class="wp-block-paragraph">Our new chop saw is a significant step up from what we had before. It handles miter cuts and bevel cuts with accuracy that older equipment simply&nbsp;couldn&#8217;t&nbsp;match, and it can cut larger material and steeper angles without&nbsp;compromising on&nbsp;the clean, tight tolerances that quality ductwork demands. In sheet metal fabrication, a precise cut at the start means better-fitting components throughout the entire system. Less rework, less waste, and faster installation on your&nbsp;jobsite.</p>



<h2 class="wp-block-heading"><strong>New Pittsburgh Machine — One Machine, Many Capabilities</strong></h2>



<p class="wp-block-paragraph">This is&nbsp;perhaps the&nbsp;biggest upgrade in the&nbsp;shop. Our new Pittsburgh machine is a multi-function powerhouse, capable of forming several of the most critical duct connection profiles all in one piece of equipment, including:</p>



<ul class="wp-block-list">
<li><strong>Pittsburgh lock seams</strong> — the standard longitudinal seam for rectangular ductwork</li>



<li><strong>S-slip and drive connections</strong> — for joining duct sections cleanly and securely</li>



<li><strong>Pipe lock seams</strong> — for round and oval duct fabrication</li>



<li><strong>Quarter-inch bends and small Pittsburgh profiles</strong> — for detailed, tight-radius work</li>
</ul>



<p class="wp-block-paragraph">Most significantly, it handles heavier gauge metal up to&nbsp;<strong>18-gauge</strong>, which is essential for commercial HVAC applications where durability and structural integrity are non-negotiable. Previously, this range of profiles would have&nbsp;required&nbsp;multiple separate machines. Now&nbsp;it&#8217;s&nbsp;all done in one place, which means faster turnaround, a more organized workspace, and consistent quality across every profile we run. It also&nbsp;eliminates&nbsp;the tearing and deformation of metal that older, worn equipment can cause,&nbsp;giving us cleaner edges and tighter seams in the finished product.</p>



<h2 class="wp-block-heading"><strong>New Air Hammers — Faster, Cleaner Duct Assembly</strong></h2>



<p class="wp-block-paragraph">Our new air hammers allow our fabricators to drive duct connections together quickly and securely. What used to take extra time and effort by hand is now done faster and more consistently, reducing assembly time without sacrificing the tight, sealed connections that efficient HVAC systems require. For customers, this means less labor time and quicker project completion.</p>



<h2 class="wp-block-heading"><strong>New High Jacks, Vise, Extension Ladder &amp; Adjustable Tables — A Safer, Smarter Workspace</strong></h2>



<p class="wp-block-paragraph">The upgrades&nbsp;don&#8217;t&nbsp;stop at the fabrication machines. New high jacks make it easier and safer to handle large, heavy duct sections. A new heavy-duty vise gives our team a secure hold for detailed work.&nbsp;And new adjustable&nbsp;work tables&nbsp;mean our fabricators are working at the right height for every task — reducing fatigue, improving accuracy, and keeping the shop floor organized and hazard-free.</p>



<p class="wp-block-paragraph">A well-organized, properly equipped shop&nbsp;isn&#8217;t&nbsp;just good&nbsp;for our&nbsp;team,&nbsp;it directly translates to better work for you.&nbsp;</p>



<h2 class="wp-block-heading"><strong>What This Means for You</strong></h2>



<p class="wp-block-paragraph">Every one of these investments comes back to the same core commitment: delivering&nbsp;<strong>better quality work, faster, at a higher standard of craftsmanship</strong>. Whether&nbsp;you&#8217;re&nbsp;working with us on a new construction project, a retrofit, or a design-build energy efficiency solution, your ductwork is being fabricated with equipment that matches the quality standards your building deserves.</p>



<p class="wp-block-paragraph"><em>We&#8217;re&nbsp;proud of what&nbsp;we&#8217;ve&nbsp;built in our shop — and&nbsp;we&#8217;re&nbsp;even&nbsp;prouder&nbsp;of what&nbsp;we&#8217;ll&nbsp;build for you.</em></p>

<p class="wp-block-paragraph">When&nbsp;a&nbsp;Community Hospital&nbsp;identified&nbsp;concerns with environmental conditions in its six operating room suites, the facilities team&nbsp;engaged&nbsp;Controlled Air&nbsp;to evaluate the existing HVAC systems and develop corrective solutions.&nbsp;</p>



<p class="wp-block-paragraph">Controlled Air was asked to review the current equipment and provide options to:&nbsp;</p>



<ul class="wp-block-list">
<li>Bring operating room air changes into compliance with current code requirements&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Resolve persistent humidity issues&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Improve temperature and comfort control for surgical staff&nbsp;</li>
</ul>



<h2 class="wp-block-heading"><strong>HVAC Engineering Assessment</strong>&nbsp;</h2>



<p class="wp-block-paragraph">A comprehensive evaluation by Controlled Air’s&nbsp;in‑house&nbsp;engineering team&nbsp;determined&nbsp;that the existing systems were originally designed in the early 1990s and no longer met modern operating room requirements.&nbsp;</p>



<p class="wp-block-paragraph">Key HVAC System deficiencies&nbsp;identified&nbsp;included:&nbsp;</p>



<ul class="wp-block-list">
<li>Air handling equipment undersized for effective dehumidification&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Insufficient reheat capacity to&nbsp;maintain&nbsp;staff comfort&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Inability of the central chilled water system to deliver the low water temperatures&nbsp;required&nbsp;for proper latent moisture removal during summer conditions&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Operating room airflow levels&nbsp;substantially below&nbsp;the current&nbsp;minimum&nbsp;requirement of&nbsp;20 air changes per hour&nbsp;</li>
</ul>



<p class="wp-block-paragraph">These conditions contributed to challenges in&nbsp;maintaining&nbsp;temperature, relative humidity, and airflow compliance within the surgical suites.&nbsp;</p>



<h2 class="wp-block-heading"><strong>Controlled Air&#8217;s Design/Build Solution </strong></h2>



<p class="wp-block-paragraph">Recognizing the urgency and regulatory importance of these issues, the hospital&nbsp;elected&nbsp;to move forward&nbsp;with Controlled Air’s design/build solution.&nbsp;</p>



<p class="wp-block-paragraph">The proposed system retrofit includes:&nbsp;</p>



<ul class="wp-block-list">
<li>A new dedicated air handling unit capable of delivering&nbsp;code‑mandated&nbsp;airflow rates&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>A chilled water coil selected&nbsp;to achieve the desired leaving air temperature at increased airflow, ensuring proper dehumidification&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>A new&nbsp;air‑cooled&nbsp;chiller engineered to supply lower chilled water temperatures independent of the existing central plant&nbsp;</li>
</ul>



<p class="wp-block-paragraph">To enhance system reliability, the design incorporates a remote evaporator configuration that&nbsp;eliminates&nbsp;the need for glycol antifreeze. This approach allows a direct&nbsp;tie‑in&nbsp;to the hospital’s existing chilled water system, providing redundancy&nbsp;in the event of&nbsp;air‑cooled&nbsp;chiller downtime.&nbsp;</p>



<h2 class="wp-block-heading"><strong>Project Status and Next Steps</strong>&nbsp;</h2>



<p class="wp-block-paragraph">The project is currently under contract, with completion scheduled for the&nbsp;end of this year.&nbsp;</p>



<p class="wp-block-paragraph">A&nbsp;parallel&nbsp;phase of work&nbsp;will&nbsp;add reheat coils&nbsp;and upgraded controls&nbsp;in surgery support areas, further improving occupant comfort while&nbsp;maintaining&nbsp;precise relative humidity control within the operating suites.&nbsp;</p>



<h3 class="wp-block-heading"><strong>Why It Matters&nbsp;</strong></h3>



<p class="wp-block-paragraph">By addressing airflow deficiencies, improving dehumidification, and adding system redundancy,&nbsp;the&nbsp;Hospital will&nbsp;gain:&nbsp;</p>



<ul class="wp-block-list">
<li><strong>Safer surgical environments</strong>&nbsp;with consistent temperature and humidity control&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li><strong>Improved staff comfort and performance</strong>&nbsp;during long procedures&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li><strong>Reduced regulatory and accreditation risk</strong>&nbsp;through&nbsp;code compliant&nbsp;design&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li><strong>Greater system resilience</strong>, minimizing downtime and operational disruption&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li><strong>A HVAC System</strong>&nbsp;ready for increasing standards and regulations.&nbsp;&nbsp;</li>
</ul>



<p class="wp-block-paragraph">A&nbsp;well-designed&nbsp;operating&nbsp;room&nbsp;HVAC system is not just a facilities upgrade, it is a direct investment in&nbsp;patient care quality, clinical efficiency, and&nbsp;long-term&nbsp;operational reliability.&nbsp;</p>

<p class="wp-block-paragraph"><em>A plan-and-spec commercial retrofit&nbsp;demonstrates&nbsp;how strategic equipment&nbsp;selection, proactive scheduling, and a sharp eye for hidden problems can translate directly into long-term operational savings.</em>&nbsp;</p>



<p class="wp-block-paragraph"><strong>Overview</strong>&nbsp;</p>



<p class="wp-block-paragraph">When&nbsp;an existing commercial utility facility&nbsp;required&nbsp;a complete mechanical&nbsp;refresh&nbsp;of its heating and cooling systems, the project team—working from a plan-and-spec design—turned to Controlled Air, Inc. to execute the installation. What followed was a coordinated effort that replaced aging, inefficient boilers with a new high efficiency boiler, upgraded the chilled water plant with a larger, quieter Trane&nbsp;air cooled chiller,&nbsp;and uncovered a hidden piping leak that had been quietly wasting water and driving up utility costs for years.&nbsp;</p>



<p class="wp-block-paragraph"><strong>The&nbsp;Result</strong></p>



<p class="wp-block-paragraph"> projected energy savings of 20–30%, improved system capacity, reduced noise impact on the surrounding property, and a facility that is better positioned for future expansion.&nbsp;</p>



<h2 class="wp-block-heading"><strong>Boiler Replacement: Switching to Lochinvar for Faster Delivery and Higher Efficiency</strong>&nbsp;</h2>



<p class="wp-block-paragraph"><strong>The Challenge</strong>&nbsp;</p>



<p class="wp-block-paragraph">The existing heating plant relied on standard atmospheric boilers that, at their best,&nbsp;operated&nbsp;at approximately 75% thermal efficiency. As the equipment aged, performance degraded further,&nbsp;meaning&nbsp;a significant portion&nbsp;of every energy dollar spent on natural gas was going straight up the flue.&nbsp;The client had a&nbsp;completion deadline, and lead times on the originally specified equipment threatened to push the project&nbsp;well&nbsp;past that window.&nbsp;</p>



<p class="wp-block-paragraph"><strong>The&nbsp;Solution</strong>&nbsp;</p>



<p class="wp-block-paragraph">Working within the plan-and-spec framework, the installation team pivoted to Lochinvar&#8217;s FTXL850 high-efficiency condensing boiler—a decision driven by two factors: superior availability and significantly better performance. The Lochinvar FTXL850 operates on natural gas at 97% thermal efficiency,&nbsp;representing&nbsp;a dramatic improvement over the legacy equipment.&nbsp;</p>



<p class="wp-block-paragraph">To keep the project on the&nbsp;client&#8217;s&nbsp;accelerated&nbsp;schedule,&nbsp;Controlled&nbsp;Air’s&nbsp;mobile boiler&nbsp;was brought online during the transition period, allowing the building to&nbsp;maintain&nbsp;heat while the permanent equipment was installed. This approach kept the project moving without sacrificing occupant comfort.&nbsp;</p>



<p class="wp-block-paragraph"><strong>Scope of Work</strong>&nbsp;</p>



<p class="wp-block-paragraph">The boiler replacement involved more than just swapping equipment. The full scope included:&nbsp;</p>



<ul class="wp-block-list">
<li>Installation of the new Lochinvar FTXL850 natural gas condensing boiler (97% AFUE)&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Decommissioning and closure of the existing flue system&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Design and installation of a new flue and exhaust configuration&nbsp;appropriate for&nbsp;high-efficiency condensing operation&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Temporary mobile boiler deployment to&nbsp;maintain&nbsp;heating continuity during construction&nbsp;</li>
</ul>



<p class="wp-block-paragraph"><strong>Efficiency Impact</strong>&nbsp;</p>



<p class="wp-block-paragraph">The jump from&nbsp;roughly 75%&nbsp;efficiency (legacy boilers) to 97%+ (Lochinvar FTXL850) is not a marginal gain—it is a fundamental transformation of how the building uses energy. For every unit of gas consumed, the new system extracts&nbsp;substantially more&nbsp;usable heat. Over the course of a heating season, that difference&nbsp;adds up&nbsp;to measurable reductions in fuel consumption and utility costs.&nbsp;</p>



<h2 class="wp-block-heading"><strong>Trane&nbsp;Air Cooled Chiller: Expanded Capacity, R-454B Refrigerant, and Quieter Operation</strong>&nbsp;</h2>



<p class="wp-block-paragraph"><strong>The Upgrade</strong>&nbsp;</p>



<p class="wp-block-paragraph">The chilled water system received an equally significant overhaul with the installation of a new Trane high-efficiency&nbsp;air cooled chiller. The replacement unit was intentionally sized larger than the original equipment—a forward-thinking decision that gives the facility the capacity to accommodate an&nbsp;additional&nbsp;chilled water coil as the building&#8217;s cooling needs&nbsp;growth.&nbsp;</p>



<p class="wp-block-paragraph"><strong>Refrigerant: R-454B</strong>&nbsp;</p>



<p class="wp-block-paragraph">The new Trane unit&nbsp;operates&nbsp;on R-454B refrigerant, a lower global warming potential (GWP) alternative that aligns with evolving environmental regulations and positions the facility for long-term compliance. As HFC phase-down requirements continue to take effect, buildings with updated refrigerants will face fewer regulatory hurdles and potentially lower service costs.&nbsp;</p>



<p class="wp-block-paragraph"><strong>Noise Reduction: A Quiet Package for Community Compatibility</strong>&nbsp;</p>



<p class="wp-block-paragraph">One of the specification requirements for this project was minimizing the acoustic impact of the new outdoor condensing unit. The Trane unit was selected and configured with a quiet package designed to reduce sound levels at the property line—an increasingly important consideration as municipalities across Connecticut and Rhode Island continue to strengthen noise ordinance enforcement.&nbsp;</p>



<p class="wp-block-paragraph">For facilities in mixed-use areas, near residential zones, or in communities with active noise regulations, specifying a quiet-package condensing unit is a straightforward way to prevent&nbsp;compliance issues before they arise. Engineers and general contractors should consider acoustic performance alongside energy efficiency when selecting outdoor HVAC equipment.&nbsp;</p>



<p class="wp-block-paragraph"><strong>Projected Savings</strong>&nbsp;</p>



<p class="wp-block-paragraph">Taken together, the boiler and condensing unit upgrades are projected to deliver 20–30% savings in overall energy consumption compared to the&nbsp;previous&nbsp;system. Factors driving those savings include:&nbsp;</p>



<ul class="wp-block-list">
<li>Higher thermal efficiency from condensing boiler technology (75% → 97%+)&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Modern compressor and refrigerant circuit efficiency in the new Trane unit&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Elimination of standby losses associated with aging equipment&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Right-sized cooling capacity that reduces short-cycling and improves system runtime efficiency&nbsp;</li>
</ul>



<h2 class="wp-block-heading"><strong>Bonus Find: Repairing a Hidden Piping Leak</strong>&nbsp;</h2>



<p class="wp-block-paragraph">During the course of&nbsp;the project, the installation team&nbsp;identified&nbsp;a leak in the piping connecting the&nbsp;air cooled&nbsp;chiller&nbsp;to the building&#8217;s chilled water system. The leak,&nbsp;located&nbsp;at the exterior connection point, had gone undetected and was causing the system to consume excess makeup water—an ongoing operational cost that the facility&#8217;s management team&nbsp;likely&nbsp;did&nbsp;not realize they were carrying.&nbsp;</p>



<p class="wp-block-paragraph">Repairing the leak was incorporated into the project scope, stopping the waste and restoring the system to proper operating&nbsp;condition. It is a straightforward example of the value that an experienced installation team brings to a project: the ability to recognize when something is wrong, communicate it clearly, and fix it—rather than simply completing the contracted scope and moving on.&nbsp;</p>



<p class="wp-block-paragraph"><strong>Key Takeaways</strong></p>



<p class="wp-block-paragraph">This project illustrates several principles that are worth carrying into future mechanical retrofits and new construction specifications:&nbsp;</p>



<ul class="wp-block-list">
<li>Equipment availability matters.&nbsp;When lead times threaten a project schedule, there are often high-performance alternatives that meet or exceed the original specification.&nbsp;Flexibility in the procurement process—without sacrificing efficiency targets—can keep projects on track.&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Condensing boiler technology delivers real returns. The efficiency gap between standard boilers and modern condensing units is&nbsp;substantial. For any project where natural gas heating is part of the design, condensing boilers should be the baseline specification, not an upgrade.&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Refrigerant&nbsp;selection&nbsp;has long-term implications. Specifying R-454B and similar next-generation refrigerants now avoids costly retrofits as HFC regulations tighten in the coming years.&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Acoustic performance is a specification item. In municipalities with noise ordinances—and their number is growing—quiet-package equipment is not a luxury; it is a risk management tool.&nbsp;</li>
</ul>



<ul class="wp-block-list">
<li>Site observation has value. Scheduled walkthroughs and attentive installation teams catch problems—like the piping leak on this project—that save&nbsp;clients&nbsp;money and prevent larger failures downstream.&nbsp;</li>
</ul>

<p class="wp-block-paragraph">In the traditional commercial construction model, a project is a hand-off: an engineer designs, a contractor bids, and a building owner manages the gap between the two. This &#8220;Plan-Spec&#8221; approach often leads to budget overruns, communication breakdowns, multiple change orders and systems that meet the minimum code but fail on long-term performance. </p>



<p class="wp-block-paragraph">At <strong>Controlled Air, Inc.</strong>, we eliminate those friction points through our <strong><a href="https://www.controlledair.com/systems/" type="page" id="36">Design-Build delivery</a></strong>. By integrating engineering, custom fabrication, and installation into a single-source solution, we take full responsibility for your facility’s climate and energy future. Not only does it save time, but it saves cost as well, by eliminating the need for a separate engineer and/or construction manager.  </p>



<h2 class="wp-block-heading"><strong>Design-Build vs. Traditional Plan-Spec</strong> </h2>



<figure class="wp-block-table"><table class="has-fixed-layout"><tbody><tr><td class="has-text-align-center" data-align="center"><strong>Feature</strong></td><td class="has-text-align-center" data-align="center"><strong>Traditional Plan-Spec</strong></td><td class="has-text-align-center" data-align="center"><strong>Controlled Air Design-Build</strong></td></tr><tr><td class="has-text-align-center" data-align="center"><strong>Accountability</strong></td><td class="has-text-align-center" data-align="center">Split between multiple firms.</td><td class="has-text-align-center" data-align="center">Single Source Responsibility</td></tr><tr><td class="has-text-align-center" data-align="center"><strong>Project Timeline</strong></td><td class="has-text-align-center" data-align="center">Linear (Design must finish before building)</td><td class="has-text-align-center" data-align="center">Concurrent (Faster speed to market)</td></tr><tr><td class="has-text-align-center" data-align="center"><strong>Cost Control</strong></td><td class="has-text-align-center" data-align="center">Known only after bidding is complete.</td><td class="has-text-align-center" data-align="center">Budget-certainty during design</td></tr><tr><td class="has-text-align-center" data-align="center"><strong>Energy Goals</strong></td><td class="has-text-align-center" data-align="center">Often an afterthought or Add-on</td><td class="has-text-align-center" data-align="center">Specialized efficiency built in</td></tr><tr><td class="has-text-align-center" data-align="center"><strong>Change Orders</strong></td><td class="has-text-align-center" data-align="center">High risk due to design/field gaps</td><td class="has-text-align-center" data-align="center">Minimal: We own the design and the build</td></tr></tbody></table></figure>



<h2 class="wp-block-heading"><strong>Why Single-Source Responsibility Wins</strong> </h2>



<p class="wp-block-paragraph"><strong>1. The &#8220;No Finger-Pointing&#8221; Guarantee</strong>&nbsp;</p>



<p class="wp-block-paragraph">In a typical project, if a control sequence fails or a unit&nbsp;doesn&#8217;t&nbsp;fit the roof curb, the contractor blames the&nbsp;engineer,&nbsp;and the engineer blames the installer. With Controlled Air, that conflict is eliminated. Because we&nbsp;are the engineer&nbsp;<em>and</em>&nbsp;the installer, we own the outcome. If a challenge arises, we solve it internally without&nbsp;the multiple change orders.&nbsp;</p>



<p class="wp-block-paragraph"><strong>2. Accelerated &#8220;Speed to Market&#8221;</strong>&nbsp;</p>



<p class="wp-block-paragraph">Time is the greatest cost&nbsp;of&nbsp;construction. Our Design-Build model allows us to overlap phases. We can begin site preparation, equipment procurement (critical for long-lead items), and in-house duct fabrication while the final engineering stamps are being applied. This typically reduces project schedules by&nbsp;10<strong>–30%</strong>.&nbsp;</p>



<p class="wp-block-paragraph"><strong>3. In-House Precision</strong>&nbsp;</p>



<p class="wp-block-paragraph">Our Branford facility houses specialized sheet metal fabrication and piping departments. Unlike firms that outsource these critical components, we&nbsp;manufacture to&nbsp;the exact specifications of our design team. This ensures that what is drawn in CAD is exactly what is installed in the field.&nbsp;</p>



<h2 class="wp-block-heading"><strong>The Specialized Advantage: Efficiency-Driven Design</strong> </h2>



<p class="wp-block-paragraph">While the Design-Build model provides the structure, our specialty in <a href="https://www.controlledair.com/energy-efficiency/" type="page" id="40">energy efficiency</a> provides the value. We don&#8217;t just build systems that work; we build systems that pay you back.</p>



<ul class="wp-block-list">
<li><strong>Our Energy Specialty:</strong> Because energy efficiency is our core focus, it makes for a better Design-Build process. We use advanced modeling to &#8220;right-size&#8221; equipment, ensuring you aren&#8217;t paying for excess capacity that wastes energy and increases maintenance costs. </li>



<li><strong>Integrated Controls:</strong> We design the mechanical hardware and the Building Automation System (BAS) simultaneously. This ensures &#8220;native&#8221; communication between systems, preventing the energy-wasting &#8220;fighting&#8221; between heating and cooling cycles common in piecemeal installs. </li>



<li><strong>Futureproofing:</strong> Our designs account for 2026 sustainability standards and ROI-driven technologies like <a href="https://www.controlledair.com/gas-heat-pumps/" type="page" id="1434">Gas Heat Pumps</a> and <a href="https://www.controlledair.com/combined-heat-power-2/" type="page" id="2272">Cogeneration (CHP)</a> from the very first sketch. </li>
</ul>



<h2 class="wp-block-heading"><strong>Long-Term Facility Value</strong> </h2>



<p class="wp-block-paragraph">An HVAC system is a 20-year investment. A Design-Build project with Controlled Air focuses on the Total Cost of Ownership, not just the initial bid. </p>



<ul class="wp-block-list">
<li><strong>Serviceability by Design:</strong> Because we also provide 24/7 service, our engineers design systems that are actually maintainable. We don&#8217;t bury components in inaccessible corners; we design for a lifetime of easy access and lower repair costs. </li>



<li><strong>Enhanced Asset Value:</strong> A high-efficiency, well-documented Design-Build system increases a building’s &#8220;Green&#8221; rating and marketability, protecting the owner’s equity against rising utility costs. </li>
</ul>



<h2 class="wp-block-heading"><strong>Partner with Controlled Air, Inc.</strong> </h2>

<p class="wp-block-paragraph">In the world of commercial construction and industrial energy, timing is often the difference between a project that pencils out and one that sits on the shelf. As we move through the first half of 2026, a massive financial window is beginning to close.</p>



<p class="wp-block-paragraph">The <strong>Section 179D Energy Efficient Commercial Buildings Deduction</strong>, a staple of the industry for two decades, is officially scheduled to sunset on <strong>June 30, 2026</strong>, under the One Big Beautiful Bill Act (OBBBA).</p>



<p class="wp-block-paragraph">For building owners, developers, and designers, the message is clear: <strong>If you haven’t started construction by mid-summer, you are leaving up to $5.94 per square foot on the table.</strong></p>



<h2 class="wp-block-heading"><strong>What’s at Stake? (The 2026 Numbers)</strong></h2>



<p class="wp-block-paragraph">Thanks to the latest IRS inflation adjustments (Rev. Proc. 2025-32), the 2026 deduction rates are the highest they have ever been. Depending on your project’s labor standards and efficiency gains, the potential savings are substantial.</p>



<h3 class="wp-block-heading"><strong>The Two Pathways</strong></h3>



<ol start="1" class="wp-block-list">
<li><strong>The Base Rate:</strong> For projects that achieve at least 25% energy savings but do not meet specific labor requirements, the deduction ranges from <strong>$0.59 to $1.19 per sq. ft.</strong></li>



<li><strong>The Bonus Rate (PWA):</strong> For projects that meet <strong>Prevailing Wage and Apprenticeship (PWA)</strong> requirements, the deduction jumps significantly to a range of <strong>$2.97 to $5.94 per sq. ft.</strong></li>
</ol>



<p class="wp-block-paragraph">To calculate your maximum potential benefit, you can use the following logic:</p>



<p class="wp-block-paragraph">$$\text{Total Deduction} = \text{Building Area (sq. ft.)} \times \text{Applicable Dollar Value (up to \$5.94)}$$</p>



<p class="wp-block-paragraph"><em>For a 100,000 sq. ft. warehouse or office complex, that is a swing of nearly <strong>$600,000</strong> in immediate tax relief.</em></p>



<h2 class="wp-block-heading"><strong>The &#8220;Beginning of Construction&#8221; Trap</strong></h2>



<p class="wp-block-paragraph">The most critical detail of the 2026 sunset is the definition of <strong>&#8220;Beginning Construction.&#8221;</strong> You do not need to finish the project by June 30, but you must prove you started. The IRS typically recognizes two methods:</p>



<ul class="wp-block-list">
<li><strong>The Physical Work Test:</strong> This requires &#8220;significant physical work&#8221; to have begun. In our industry, this means foundation excavation, setting anchor bolts, or permanent installation of components. Preliminary site clearing or design work <strong>does not count</strong>.</li>



<li><strong>The 5% Safe Harbor:</strong> You must have paid or incurred at least <strong>5% of the total cost</strong> of the energy-efficient property before the deadline.</li>
</ul>



<h2 class="wp-block-heading"><strong>Why Proactive Planning Matters Now</strong></h2>



<p class="wp-block-paragraph">Waiting until May to &#8220;talk to the engineers&#8221; will be too late. To secure this deduction, a project requires:</p>



<ol start="1" class="wp-block-list">
<li><strong>Energy Modeling:</strong> A third-party professional must model the building against the ASHRAE 90.1 standards to certify the 25%+ savings. Although the IRS does not mandate a specific modeling protocol, it is an accepted way of demonstrating the savings for the deduction. The modeling procedures come from regulation and practice. Controlled Air utilizes <strong>Carrier’s Hourly Analysis Program (HAP)</strong> to provide the precise energy modeling required for high-performance building design. This software is an industry standard for performing the 8,760-hour simulations necessary to demonstrate compliance with <strong>ASHRAE 90.1</strong> and federal tax requirements. By leveraging this ASHRAE-approved tool, we ensure your facility&#8217;s projected energy savings are both technically accurate and professionally certified.</li>



<li><strong>PWA Documentation:</strong> If you are aiming for the $5.94 bonus rate, your payroll and apprenticeship records must be airtight from day one.</li>



<li><strong>Designer Allocation:</strong> For government or non-profit buildings, the tax-exempt owner can allocate this deduction to the <strong>Primary Designer</strong> (architect, engineer, or design-build contractor). This is not automatic, but an eligible entity can allocate the deduction.</li>
</ol>



<h2 class="wp-block-heading"><strong>The Bottom Line</strong></h2>



<p class="wp-block-paragraph">Section 179D has been a cornerstone for financing HVAC retrofits, lighting upgrades, and high-performance building envelopes. After June 30, that &#8220;extra&#8221; capital disappears from the market.</p>



<p class="wp-block-paragraph"><strong>Is your pipeline ready?</strong> Our team is currently prioritizing site audits and energy modeling for clients looking to lock in their 179D eligibility before the summer deadline.</p>

<p class="wp-block-paragraph">If you manage a facility, you know the feeling: the utility bill arrives, and the numbers are high, but you aren&#8217;t sure <em>why</em>. You can see the total cost, but you can’t see the wasted kilowatts bleeding out from a miscalibrated chiller at 2:00 AM or a control loop fighting itself in the east wing.</p>



<p class="wp-block-paragraph">For decades, finding these invisible drains required expensive consultants and weeks of manual labor. But today, Artificial Intelligence (AI) is changing the game, turning raw data into a roadmap for efficiency.</p>



<p class="wp-block-paragraph">At <strong>Controlled Air</strong>, we are taking this a step further. We believe the best results come from combining cutting-edge AI with seasoned human expertise. That’s why we are thrilled to introduce our new <strong>Energy Evaluation Program</strong>.</p>



<h3 class="wp-block-heading">Why AI Matters for Your Building</h3>



<p class="wp-block-paragraph">Building analytics used to be reactive—you fixed things after they broke or after the bill skyrocketed. AI shifts this to a <em>proactive</em> approach. By processing vast amounts of data instantly, AI can identify patterns that no human could spot on a spreadsheet.</p>



<p class="wp-block-paragraph">However, data without context is just noise. To make a real impact, you need someone who knows how to interpret that data and translate it into mechanical reality.</p>



<h3 class="wp-block-heading">Introducing Our New Program</h3>



<p class="wp-block-paragraph">We are inviting you to experience an in-depth look at your building&#8217;s energy consumption through our new program, spearheaded by our energy efficiency expert, <strong>Lou Savarese</strong>.</p>



<p class="wp-block-paragraph">Lou brings decades of expertise to the table, and by pairing his knowledge with the benefits of AI, we can evaluate your building&#8217;s usage with forensic precision.</p>



<h4 class="wp-block-heading">The Offer: A Complimentary Forensic Analysis ($3,000 Value)</h4>



<p class="wp-block-paragraph">We want to prove the value of this system before asking you to commit to anything. That is why we are offering a <strong>complimentary forensic analysis</strong>—a service valued at $3,000—completely free of charge.</p>



<p class="wp-block-paragraph"><strong>How it works:</strong></p>



<ol start="1" class="wp-block-list">
<li><strong>Secure Integration:</strong> Simply grant us secure access to your utility accounts.</li>



<li><strong>The Portal:</strong> We seamlessly integrate your data into our innovative analytics portal.</li>



<li><strong>The Analysis:</strong> Our system, guided by Lou’s expertise, digests the data to pinpoint exactly <em>when</em> and <em>where</em> your highest energy demands occur.</li>
</ol>



<h3 class="wp-block-heading">What You Get</h3>



<p class="wp-block-paragraph">This isn&#8217;t just a graph showing you used a lot of power in July. You will receive a <strong>detailed, actionable report</strong> outlining your current energy footprint.</p>



<p class="wp-block-paragraph">More importantly, you will get a tailored list of potential modifications. We look for the &#8220;low-hanging fruit&#8221; first—minor adjustments to your existing control system that cost little but save a lot. From there, we outline recommendations for equipment upgrades specifically targeting your highest energy consumption areas.</p>



<h3 class="wp-block-heading">No Risk, High Reward</h3>



<p class="wp-block-paragraph">There is <strong>no obligation to proceed</strong>. You get the report and the insights regardless of what you decide to do next.</p>



<p class="wp-block-paragraph">However, should our findings spark your interest, we are ready to provide a full analysis and comprehensive proposals for the necessary updates to turn those insights into savings.</p>



<h3 class="wp-block-heading">Ready to See What You’ve Been Missing?</h3>



<p class="wp-block-paragraph">Stop guessing where your energy budget is going. Let us show you.</p>

<p class="wp-block-paragraph">When a world-class equipment manufacturer needs to upgrade their own facilities, they need a partner who can manage the job from the structural engineering down to the final software programming.</p>



<p class="wp-block-paragraph">We are proud to announce the successful completion of a massive HVAC integration for the&nbsp;<strong>Yanmar Tractor and Parts Warehouses</strong>. For this project,&nbsp;<strong>Controlled Air</strong>&nbsp;served as the lead organizer and turnkey provider, delivering a seamless &#8220;design-to-execution&#8221; experience that modernized the climate control for two massive industrial spaces.</p>



<p class="wp-block-paragraph">Here is a look behind the scenes at how Controlled Air managed this complex infrastructure project.</p>



<h3 class="wp-block-heading"><strong>The Scope: Total Project Management</strong></h3>



<p class="wp-block-paragraph">This was not a simple &#8220;swap and drop&#8221; equipment changeout. This was a comprehensive facility upgrade.&nbsp;</p>



<p class="wp-block-paragraph">Beyond the mechanical installation, our team managed the critical logistics to keep the project running smoothly:</p>



<ul class="wp-block-list">
<li><strong>Structural &amp; Architectural:</strong>&nbsp;We handled the structural reviews and the installation of pre-engineered deck support systems to safely hold the new heavy-duty equipment.</li>



<li><strong>Roofing &amp; Rigging:</strong>&nbsp;From crane rentals and rigging to the necessary roofing repairs and curb installations, we ensured the building envelope remained secure.</li>



<li><strong>Utilities &amp; Safety:</strong>&nbsp;We managed the complete gas piping infrastructure, electrical connections, and fire alarm tie-ins (including duct smoke detectors).</li>
</ul>



<h3 class="wp-block-heading"><strong>The Technology: High-Efficiency Synergy</strong></h3>



<p class="wp-block-paragraph">One of the most exciting aspects of this project was the equipment selection. We paired high-performance air handling with Yanmar’s own cutting-edge engine technology.</p>



<p class="wp-block-paragraph">To condition this massive space, we furnished and installed a robust system designed for longevity and efficiency:</p>



<ul class="wp-block-list">
<li><strong>Air Handling:</strong>&nbsp;Seven (7)&nbsp;<strong>Aaon 30-ton Rooftop AHUs</strong>, fully equipped with VFD blowers for energy efficiency and a high-grade filtration system using MERV 8 and MERV 13 filters.</li>



<li><strong>Heating &amp; Cooling:</strong>&nbsp;These units are powered by&nbsp;<strong>fourteen (14) Yanmar 14-ton Gas Heat Pumps (GHP)</strong>. This 2-pipe natural gas system utilizes Yanmar’s engine technology to provide efficient heating and cooling with reduced electrical demand.</li>



<li><strong>Reliability:</strong>&nbsp;The system includes custom 14&#8243; roof curbs, stainless steel drain pans, and vibration isolation to ensure quiet, long-term operation.</li>
</ul>



<h2 class="wp-block-heading">2. The Parts Warehouse</h2>



<p class="wp-block-paragraph">Similar to the tractor facility, the parts warehouse received a top-tier upgrade:</p>



<ul class="wp-block-list">
<li>Three (3)&nbsp;<strong>Aaon 30-ton Rooftop AHUs</strong>&nbsp;paired with&nbsp;<strong>six (6) Yanmar 14-ton GHPs</strong>.</li>



<li>This setup ensures that valuable inventory is kept at consistent temperatures while maintaining high air quality standards through double-wall cabinets and advanced filtration.</li>
</ul>



<h3 class="wp-block-heading"><strong>Intelligent Controls</strong></h3>



<p class="wp-block-paragraph">Controlled Air furnished and installed a complete&nbsp;<strong>Johnson Controls</strong>&nbsp;ecosystem to tie the entire facility together.</p>



<p class="wp-block-paragraph">We deployed panel-mounted controllers across both warehouses, complete with all necessary sensors, relays, and current switches. For the Parts Warehouse, we installed a&nbsp;<strong>Johnson Controls Supervisory front-end controller</strong>. This web-based user interface allows facility managers to monitor the system remotely, ensuring peak performance and immediate diagnostics.</p>



<h3 class="wp-block-heading"><strong>The Controlled Air Difference</strong></h3>



<p class="wp-block-paragraph">By handling everything from the certified air balancing and start-up testing to the permits and gas meter coordination, Controlled Air ensured that Yanmar could focus on their business while we handled their building.</p>



<p class="wp-block-paragraph">We are thrilled to hand over a facility that is energy-efficient, structurally sound, and controlled by the latest in building automation technology.</p>
