The HVAC industry is full of mainstream mistakes. Here’s a statistic from ENERGYSTAR, "recent field studies suggest that approximately 75% of installed cooling equipment may have an incorrect amount of refrigerant. Incorrect refrigerant level can lower efficiency by 5 to 20% and can ultimately cause premature component failure, resulting in costly repairs that could have been prevented."

ACS put ThuroTech in place to uphold the proper techniques and practices on a CONSISTENT basis. Unfortunately, even when an HVAC company get customer service, culture, and reputation correct, it doesn’t mean they are giving a proper installation. ACS doesn’t want your proper installation to depend on which Technician goes to your home, or how someone is feeling on the particular day they are at your home installing your new system.

Our goal is simple, to get you the system you paid for!

ACS is aiming to serve you with amazing customer service while providing an exclusive standard made of training, process, accountability, and pride. It’s called:
