I signed up for their annual maintenance plan ($199/yr, 2 service visits). They came out to do the…read moreAC checkout, since the system was 1 year old. Everything checked out fine. I didn't appreciate the $2,000 in "stuff" that I was offered to buy, but, I haven't seen an HVAC company that doesn't do that. This was on a Friday morning. The problem didn't arise until my wife and I tried to take showers on Saturday. There was no hot water. Went down to check the hot water heather, which is next to the furnace. Instead of the dial being on "hot", it was on "pilot". How it got turned to pilot, I have no proof, but, I would imagine that the tech from Summit, either accidently, or for some reason on purpose, turned it to pilot. I sent a message thru the Summit HVAC website about what had happened. I got a call from the service manager on Monday. He said that there was no way, no possibility whatsoever, that his tech, in any way, shape, or form, could have moved that dial on the water heater. When I said "I guess it's a mystery", he said "sure is". But, he reassured me that Summit was still there to take care of me. I told him "that wasn't going to happen". I said I wanted out of the annual agreement and half my money back (I had paid the full $199). I got less back than I asked for, but, that is another story for perhaps another time. Needless to say, I do not need these people in my home. But, for everyone else, if you want techs that are infallible, and a company that will stand behind the infallibility of those techs, perhaps Summit HVAC is for you.
