Customer Reviews

Read ReviewsWrite a Review

Bill and Troy were wonderful to get my new AC unit installed just before the hot weather came. I was very impressed to get exterior shots sent to me since my unit is on the roof. Outstanding!

Jon B.

Keefe HVAC is a professional and truthful company. They previously repaired my AC machine and the service was great. When I started having a new issue I discussed it with them and they said that it wasn’t worth spending the money. They’ve been great each time we’ve used them.

Michael E.

Bill and Troy were great. Explained everything and were polite. Had new ac installed the next day at a reasonable price. Michael was easy to deal with, I would recommend.

Joe H.

Troy was awesome! He took time to explain everything to me and even educated me on the workings of a unit. He is very knowledgeable and friendly. Everything was clean.

Lorenzo P.

The AC was not blowing cool air. Your customer service reps were all very nice to me. They called me to verify that the technician was on his way and that he was there. Bill called me again the next day to make sure everything was ok. It was really good customer service.

Wesley C.

Excellent company and techs. The company has been very attentive. I highly recommend Keefe HVAC any time I’m unable to contact the original installer of my furnace/air conditioning I will most definitely call them!!
