Since Weis was sold I have had many poor experiences.

Lori S.
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!!

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.

2023-24 Lennox furnace check performed today. Samuel L was very nice - consistent with all Weis personnel we’ve encountered. The service visit was ontime, thorough, attentive and we feel confident in the attention Weis brings to our annual HVAC systems reviews.

I’ve been using Weis/Classic for over 10 years. They typically spend over 30 min going over the system - very thorough. They always take the time to answer questions.
