"Nice furnace"

5.0 rating
Very Satisfied

I purchased a new comfortable furnace for my house. Not only is it really efficient, it is much quieter than my old one. They have a no lemon warranty that the other brands didn’t offer!

"Junk from day 1"

3.0 rating

This furnace has not worked right since it was installed in 2005. It’s a piece of junk. I would never buy another one of these, no matter what the HVAC guy says. He doesn’t care; he comes back 2 to 3 times a year to replace parts. He must sell these to everyone to ensure he has continuous business. It is -27 here today and we have no heat once again. We had it serviced in October; what a waste of money. The original oil furnace from 1940 that we replaced was at least reliable. I curse the day we got this furnace. Another sleepless night freezing. Our children are going to school everyday cold and unhappy because the HVAC tech keeps saying I will be there, but he never shows up. We got a lemon and do not recommend a Comfortmaker…..more like cold maker. Junk, junk, junk.

"Extremely Disappointed"

1.0 rating
Very Unsatisfied

The furnace is now 9 years old. For the past 3 years, it’s required service at the beginning of each heating and cooling season. The latest issue is the control module for the variable speed blower motor. It is no longer available, and the replacement kit is over $600. I would never buy an ICP product again.

After reading so many negative comments about Comfortmaker, I was hesitant to go with them. But my contractor told me how the significant components are made in USA and of the highest quality and are actually a division of Carrier and United Technologies. I believed him, he said they are reliable and perform as good or better than anything he has used. I was convinced and could not be happier. Great product – better performance and saving me big time gas and electric!!!

"Great product when installed by someone that cares"

5.0 rating
Very Satisfied

I had a young man named Josh put my family in a VS 2-stage system 2 years ago and we love it. Our neighbors had another company put a different brand in — not all that good for them. But what I found interesting is on mine after they got the unit running they adjusted blower speeds, gas pressure and even checked what they called static and the neighbors contractor did none of this but they keep having trouble. So I guess it has a lot to do with the installer
