Our A/C unit stopped running this past Friday afternoon (7/25)… I came home from work, and it was 80 degrees inside our home! I called “Weis Comfort Systems” and they were able to get a technician to our home THAT evening! Problem solved. The technician was friendly and professional. This is the first time I’ve used Classic Aire Care, as I was a previous Weis Comfort Systems customer (my uncle started that company many years ago). I am very happy that CAC is continuing the wonderful customer service that my uncle and his sons insisted on for so many years. Highly recommend!!

Bill Colin did an excellent job cleaning my air conditioner today. He is an excellent worker and takes great care of my equipment. Would recommend Bill Colin to work on your air conditioner and furnace always does a great job on both.

I would not recommend this A.C. and cooling company to anyone. The previous owner of my house bought a system from them in 2020, and from what I can tell, it’s undersized for the space. It won’t cool the house below 80 degrees, no matter how long it runs. When I called them for help, they refused to even come take a look unless I paid them more. No sense of responsibility, no customer service — just trying to squeeze more money out of me. Total waste of time.

Weiss installed our furnace about 2 1/2 years ago. The company was great to work with. We lost our AC during some of the hottest days in August and Weis brought out some window units for us to use in the couple of days prior to the new unit being installed Yesterday their tech, Bill came out to check on the unit to see why it wasn't cooling properly. He had done the research on past calls to our house and was able to quickly assess the issue. He wrote a detailed description of what was going on, on our invoice so we had the documentation for any future service calls. I would definitely recommend Weis for anyone looking for a reliable HVAC company.

Weis Comfort Systems has very competitive rates & Frank M. is an excellent, knowledgable HVAC service tech. He has kept our HVAC units in good condition & functioning for years so our home stays comfortable year round. I am pleased with their services.
