"Repairs"
I had this furnace installed 3 years ago. I have had to replace pressuse switches every year at $200.00 a piece. Last year my installer said Coleman had problems with the switch and redesigned it. Cross my fingers $600.00 later it works this year. I have had a coleman at my last home that lasted 25 years and no problem. I even sent Coleman a E-mail in regard to this issue and never heard a word from them. Where did thier customer service go?

"JUNK FURNACE"
I live in a double wide mobile home-my husband and I purchased it brand new in 2002- 4 days ago the furnace went out-when I called "the furnace guy" to look at it they told me - they could not fix it as there were 3 very large and deep cracks in the wall of the furnace, and it has been leaking carbon monoxide gas, and if they did try to fix it-it would catch the insullation on fire. they showed me these large cracks, and also informed me that the furnace was too large for this mobile home- another reason why it was not efficient! When I called coleman with this information-they told me that the warranty of that model was expired last year-and it was not thier problem. lesson do not ever buy a coleman furnace!

"Night Mare Heating"
I have had this Night Mare Coleman Furnace Model # DGAA056BDT* for 3 nights and it is so noisy and loud I can't sleep . Comes on and off every hour. Blows warm air instead of Hot. I turned it off for the night and in the morning it took 3 hours for the temperature to rise 10 degrees. I am really disappointed in this furnace. I am going to have my old one replaced.

"Furnace Is Junk"
This Coleman DGAA077BDT* furnace was a replacement for a 21 year old Intertherm. Soon after the contractor installed the furnace we started having problems. At the beginning of every heating season from 2005 until present, we have had to replace pressure switches and ignitors. The outer doors have plastic holders that have been broken by service men removing doors. The filters do not stay in place when you replace them. This heating season, another ignitor and pressure switch problem and then the contractor discovered a 4 inch crack in the heat exchanger. The contractor himself called the unit "a lousey lemon which should be replaced by the factory" I have written to Coleman Heating and Cooling 3 different times about the furnace and have never received a response. The contractor and the distributor both claim to have been fighting with Coleman for a replacement, but to no avail. They finally replaced the heat exchanger, but wanted $890 labor to install. Told them we couldn't afford that so they "reduced" it to $400. We are in our 80's on social security and can't afford this kind of ripoff. Finally hired a different contractor and he has the furnace running at present. Of course this cost us another service call and parts. Coleman should be banned from making these kinds of products.

"2 pieces of JUNK"
Unfortunately, we bought 2 furnaces, dgaa090bdta and dgah077bbsa, they are both junk! Replaced several parts on the dgah, ignitors (twice), blow motor and circuit board and now it has a hole in the heat exchanger. Repairman checked the other and it's already cracked. Should have left the old less efficent models in, because the newer ones are much less efficent once you consider all the repair bills. Will never buy or recommend Coleman again!

"Mobile Home"
Jan 2009 We replaced 20 Year Mobile Furnace with a Coleman DGAA077BDTB..(same model of furnace someone else is Very unsatisfied with) and Feb 2010 had to have Combustion Air switch replaced at over $360 as our one year warranty was over... My husband said he did not know about the one year Warranty or he would never have bought it. When the fellow came out to replace the Switch he advised us to buy another( $360) as they are the first to go. also when the furnace turns on The Combustion Air switch is the first to come on and oh is it noisy...some times it wakes us up. Any way as of Dec 16 2010 the Combustion switch is getting loader and the squirrel Cage is making a few extra rounds after the furnace shuts down... so another $360 and hopeful only a bearing. I have a letter in with Coleman now, but from all the review I have read they are not going to Stand by their name going to be buying some floor heater as I am sure it will break down this winter. Must be prepared...sad to say DO NOT buy Coleman
