The Coleman DGAA product line is an 80% AFUE gas furnace designed formanufactured homes. Compact in size, this model features zero clearance and can easily be installed in tight spaces in mobile or modular homes.
Coleman advertises this line as “air conditioning ready” with blowers capable of handling up to 4 tons of air conditioning and built-in coil cabinets designed to work with cooling units. According to Coleman, these features allow for easy installation and highly efficient operation.
In addition, the DGAA series features a fail-safe auto ignition system, aluminized steel heat exchanger, scratch resistant panels, and is equipped with a convertible gas valve and gas orifices for natural or propane gas. The DGAA also uses universal disposable filters.
Junk, had it installed about 15 years ago and have worked on it a lot. Usually just cleaning the blower unit and flue pipe. This year has been different. Went to clean the heat sensor and it was very clean, but the plate that spreads the flame laying in the bottom of fire box. Upon further inspection that flame has directly been hitting the back of the fire box, cracking my heat exchanger all to hell. Needless to say it is not working again. Thank God I have a wood burning stove. Hire some new technicians or just stop. Judging from other replies, I’m not alone. Stop making furnaces or you’re going to get someone killed with your faulty product. I will never purchase from Coleman again.
I had this unit installed in my elderly mother’s place October 2013 and I have had to pay a service fee and replace the inducer motor every year since. I contacted Coleman about this and the customer service is as awful as the furnace. After explaining that I have had to have this motor replaced every year since installing the unit, she simply replied it’s out of warranty, so too bad. Also, the furnace has a plastic door which melted during the first season. Who puts plastic parts on a heating unit? Absolutely do not buy this product. I will be replacing my mother’s furnace again with anything not made by this company or its affiliates. I own numerous properties and manage over 100 others. I will never allow any of Coleman’s products to be used in any of them ever again. Nor will I allow anything produced by the company Style Crest.
"WHAT A HUNK OF JUNK"
Mine didn’t make it threw a year without giving me trouble. I have replaced just about everything on it that can be replaced, and I still sometimes will not cycle. Never ever again.
"Concerned about reliability"
Dislike the fact that the blower is very loud. This seems to be one of the bigger complaints from the reviews that I have read. The concern I have is when the flame ignites the noise makes is a very loud bang and I mean loud this worries me a lot. Is this or is this not a normal thing. Is this something that could be a danger. Would I buy this brand again probably not. But I’m stuck with it. I just hope it don’t blow up.

"A/C unit Evcon & Coleman furnace"
After unit was installed on January 31, 2016, the heater worked fine through the winter. The blower was strong and running quietly. Great on gas bill. But went to turn the A/C on for the first time and it was not cooling at all. Called contractor, he came out the same day and said it was the expansion valve or compressor. Not too happy to hear this. He said he would get the part and come back the next day. Called him the next day and asked him to come back the day after, due to an appointment that day I would not be home. Well it’s the next day and he hasn’t fix it yet. I will be disappointed if this doesn’t fix the problem and it takes a compressor, I would rather have another unit in place of this one. Note the reason the furnace unit was replaced due to part n/a plus the heat exchanger had burned through the metal and damaged the wall from the flames coming out of the furnace wall. The reason this happen was due to dirt, wasps had built their mud nest over the flue and would not let out the heat thru the stack. I would recommend a screen be put over the top of the flue opening to keep this from happening and causing the home to catch on fire. Only reason mine didn’t was because of the n/a part and when we pulled out the old furnace we found a hole on the side of the furnace letting flames reach the wall. If you have any question please feel free to call. This might save some lawsuits and some lives.
