Product Reviews:

Our furnace and air conditioner are both Coleman, and they have lasted for
Our furnace and air conditioner are both Coleman, and they have lasted for ten years. The AC always needs replacement although this is not part of the furnace and we cannot complain about this. The high energy conversion rate as a result of the AFUE high levels makes it the best for me. I have not had any replacements or repairs so far, and I hope I will not have any problems with my furnace. The price is manageable, and I would recommend this to anyone who needs a gas furnace that is not too pricey and works efficiently.

Coleman furnaces are some of the best high-efficiency furnaces so no matter what your budget is, you can probably find room for a high-efficiency or ENERGY STAR certified upgrade. Coleman has a decent selection of heating systems that includes basic single-stage models, two-stage furnaces, and more advanced systems with modulating burners. All Coleman furnaces are backed by excellent warranties that cover parts, heat exchangers, and even labour.

I agree that the installation is the main point when it comes to gas furnaces. I am nothing but satisfied by this brand of Coleman. My previous gas furnace kept on leaking and made my house messy, and I had had to clean often. I always called the technician to do repairs who later on recommended to me the Coleman unit. It’s highly efficient without too much cost of the gas bill. It was also affordable, and the installation was easy.

Being HVAC technician, I have installed this unit on some my clients, and all I can stress is that it is a good unit as long as the installation process is performed by someone who perfectly knows when he is doing and not just anyone. The mistake that many users do is to install a unit without the help of an expert, this leads to poor installation, and the unit starts having problems too early, and some do not even end. Proper installation of any unit is essential if you want your furnace to last long enough. The only bad thing I had with this unit is the unit being a little noisy; the manufacturer should do something about the noise. The price is friendly, and I would recommend this to my clients at any given time.
