It is important to investigate the heating and air conditioning contractors before choosing the right one for you. There are contractors will varying levels of experience, cost, and reputation. Unfortunately there are some out there who do not have the experience to do things right. Recently we were hired to fix a RTU installation. The RTU was installed wrong, as well as illegally. The unit was supported off the roof with 2 x 4’s rather then steel. Wood left to the elements rots.
As a business owner it is important to make sure that you get proper installation on any new equipment that you purchase for your building. Don’t get stuck paying for the same job twice and don’t let this happen to you.
