What Our Clients Are Saying

We had a wonderful experience with Critical HVAC Systems! The technician was professional and knowledgeable. He recommended exactly what was needed, and explained in a concise and easy way what was wrong and how much the estimated repair would be. Prices are fair. They go the extra mile and are extremely competent for a residential HVAC company. I definitely recommend this company!!

Ms. Carolina, Home Owner

Our ambulatory surgery center was completed and became operational in 2005. We are accredited by Medicare and AAAHC. Therefore we have very high, very strict standards for our air handling equipment. When I became the administrator, we developed some problems with humidity and temperature regulations. I consulted Critical HVAC Systems who discovered controls that had been installed incorrectly. They diagnosed, repaired and had us back in compliance in a short time. We have been using their service for maintenance on our equipment. They contact me, set up appointments and are always punctual. I may worry about many aspects of the maintenance of our surgery center but I never concern myself with the HVAC because we are in the best of hands. They watch my back!

We have been very satisfied with the service from Critical HVAC Systems. They get the job done and are highly responsive. When hiccups occur they are sure to let us know and make the necessary course correction.
