We Provide New Construction HVAC Services

It goes without saying that the HVAC system in any given building is a source of basic comfort for building occupants and visitors. These systems are complex, though, and most standard construction companies don’t actually know much about them.

So when you are having a new home or property constructed in the Birmingham area, you want a team on your side that will assist you in making the right decisions, from correct system size to the right efficiency rating. We’ll stick with you through the entire construction process to ensure 100% customer satisfaction!

Don’t Let Faulty Ductwork Affect Your Comfort

Your air ducts are typically installed out of sight, in your walls or within crawlspaces. This makes it difficult to detect when your ductwork is damaged or breached. Unfortunately, air lost through damaged ductwork can account for about 30% of your total energy usage, meaning you are paying for conditioned air that’s never making it into your living space.

Signs that you might need ductwork services include noisy ductwork and poor HVAC efficiency. Your air ducts make a little noise anyway, with the fluctuation of temperatures, but they shouldn’t be rattling or hissing. And if you notice your heating or cooling bills are rising despite comparable use, faulty ductwork can certainly be to blame.

We Service Unique Spaces

There are some areas in a home or a business that require a little extra training and knowledge to understand just how to keep the space as comfortable as possible. At Sullivan Service Co., we have expertise in conditioning these difficult areas, which include:

  • Basements
  • Computer Rooms
  • Bonus Rooms

Each of these areas comes with unique challenges when it comes to cooling and heating, in addition to maintaining proper humidity levels and high air quality.
