After getting many different quotes from several different companies in my search to replace my 17 year old system, I finally decided to go with the Comfortmaker brand. Its been two years now, and I couldn't be happier! I went with the variable speed/inverter option for my home. In my search, I read countless reviews from all the top brands out there.. I realized in my search more people will leave a "bad" review rather than a "good" one. Its like when you go out to eat, and have a horrible experience. The first thing you want to do when you get home, is leave a bad review. Same thing applies here. This system pulls so much moisture out of the air! I can leave my thermostat at 77 degrees and 52% humidity and it feels amazing, and that's here in Houston, Texas. The house feels crisp/clean/enjoyable to be in, its a hard feeling to describe, but I'm very happy I went with Comfortmaker brand and the Variable speed full system. If you can afford to go this route, I definitely recommend this option, you'll be amazed and won't regret it at all!

Very very surprised on this system. I had this system installed form a neighborhood contractor I was very skeptical on this system do to I never heard of it. After going through everything with and all the other quotes I ended up having this installed. This system is very quite and helped my energy bills. I have had no issues with this furnace it was installed 1/15/2015. I dont write many reviews but waited 3 years on this review because I wanted to make sure I got something quality. But like my installing company said as long as it is installed correctly I wont have problems with it. Highly recommend it and their ac systems.

A Comfortmaster RPJ II furnace was installed in my house on January 3, 1996
A Comfortmaster RPJ II furnace was installed in my house on January 3, 1996. What I like about this furnace is that it has performed flawlessly since I moved into this house in 2009. The only maintenance that has been required is that I change the filters. It was repaired on December 1, 2005 by the previous owner of this house, my father. He kept meticulous records of such things. This house was built in 1955. I am not aware of the make of the previous furnace. I don't know the exact cause of the 2005 malfunction, but the repair went well. I haven't had any problems since I bought the house in 2013. I am part of my gas company's emergency repair insurance program, so I feel confident that I will always have a working furnace. I would recommend the Comfortmaster RPJ II furnace to a friend if they asked me. I am not an expert, but this furnace is reliable.
