Our customers here is a little about what they 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!!

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.

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!

Critical HVAC Systems has been providing preventive and regular maintenance for our HVAC system for over a year, and we are exceedingly pleased with the service provided to us. We feel as though we have finally found the company who can address ALL our HVAC issues – a “one stop shop” for HVAC – which makes life so much sweeter! Critical HVAC Systems has the personnel to address both controls issues as well as the issues of a nearly 10 year old building with aging rooftop equipment. When an HVAC issue arises, it’s ALWAYS an emergency…at least to whomever is hot or cold. We know Critical HVAC Systems is a text or call away. Their responsiveness is exceptional. If it is humanly possible, they will get to us and help us through the crisis that same day and often within minutes or hours. Beyond that, Critical HVAC Systems technicians are able to log into our system remotely and adjust controls which may be the source of our issue, thus avoiding a costly trip to our site.

I simply couldn’t be more pleased with the service received from Critical HVAC Systems, and in particular Harold and Jason. Their skills and knowledge are exceptional. I trust their judgment and believe they are looking out for our best interests, and I greatly value their quick response time.

(Critical HVAC Systems)… went “beyond the call of duty” this morning to check out the cooling tower at the school. The Critical HVAC Systems team assigned to this site, typically DO go “above and beyond” to ensure that the faculty and students are able to conduct classes without interruption.
