At Controlled Air, Inc., we eliminate those friction points through our Design-Build delivery. 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.  

Design-Build vs. Traditional Plan-Spec 

Why Single-Source Responsibility Wins 

1. The “No Finger-Pointing” Guarantee 

In a typical project, if a control sequence fails or a unit doesn’t fit the roof curb, the contractor blames the engineer, and the engineer blames the installer. With Controlled Air, that conflict is eliminated. Because we are the engineer and the installer, we own the outcome. If a challenge arises, we solve it internally without the multiple change orders. 

2. Accelerated “Speed to Market” 

Time is the greatest cost of 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 10–30%. 

3. In-House Precision 

Our Branford facility houses specialized sheet metal fabrication and piping departments. Unlike firms that outsource these critical components, we manufacture to the exact specifications of our design team. This ensures that what is drawn in CAD is exactly what is installed in the field. 

The Specialized Advantage: Efficiency-Driven Design 

While the Design-Build model provides the structure, our specialty in energy efficiency provides the value. We don’t just build systems that work; we build systems that pay you back.

• Our Energy Specialty: Because energy efficiency is our core focus, it makes for a better Design-Build process. We use advanced modeling to “right-size” equipment, ensuring you aren’t paying for excess capacity that wastes energy and increases maintenance costs. 
• Integrated Controls: We design the mechanical hardware and the Building Automation System (BAS) simultaneously. This ensures “native” communication between systems, preventing the energy-wasting “fighting” between heating and cooling cycles common in piecemeal installs. 
• Futureproofing: Our designs account for 2026 sustainability standards and ROI-driven technologies like Gas Heat Pumps and Cogeneration (CHP) from the very first sketch. 

Long-Term Facility Value 

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. 

• Serviceability by Design: Because we also provide 24/7 service, our engineers design systems that are actually maintainable. We don’t bury components in inaccessible corners; we design for a lifetime of easy access and lower repair costs. 
• Enhanced Asset Value: A high-efficiency, well-documented Design-Build system increases a building’s “Green” rating and marketability, protecting the owner’s equity against rising utility costs.

Carrier’s Hourly Analysis Program (HAP) was used to provide energy calculations and comparisons. The analysis was performed by first constructing the baseline.  From the output of the building simulation, calculations showed that by implementing the proposed Patterson-Kelly efficiency boilers, an annual savings of 19,139 CCF was projected when compared to the ASHRAE code minimum 82% efficient boilers. At the calculated average utility rate of $1.2567^[1] per CCF, this would amount to approximately $24,051 in savings annually.

When the project was completed, they received a $64,418 incentive for the boiler upgrade.
