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.

We live in a manufactured home and were replacing an older unit. Brands
and models were limited. But this one hums 24/7 (unless we have a power outage).

I had this unit installed 6 years ago and have yet to have a service call. So
impressed with Coleman, I added the A/C last summer. After 1 season of
cooling all is good. Coleman earns my trust and satisfaction.

Junk, junk, junk
Have had the furnace for 4 years. It worked OK till now. Now it has an ignition
failure that comes and goes weekly, I have changed the flame sensor and
computer and still have the problem, and all safety circuits seem to be
functioning properly but it still keeps shutting down. My brother-in-law
bought the same furnace shortly after me and has had and still has similar
problems since new. He even hired the professionals who installed it plus
others and still has problems.

Best HVAC in Ventura County, CA
We had a personal friend recommend Doug Fairweather HVAC for our
upcoming replacement of our entire HVAC system. We were getting an
estimate from 600 miles away and Doug's staff was prompt in replying
to any request we made via email. The price was good and the install
went smoothly. The install team was fast and efficient. Done in one
day. The Coleman furnace was a perfect fit and works perfectly. The
original Coleman furnace lasted 27 years and I expect the same from
this new unit.

It is a very clean unit. So far it is performing much better than the
last unit I had. I like the way the filters are placed in the unit doors
as they dont have to be bent now like they used to be. Coleman has
always fulfilled my and my family's needs and I have had pretty good
luck with them. The jury is still out for now but with a new furnace and
air conditioner we should be good to go for a while now.

Mobile Home furnace replacement
My 21-year-old furnace decided to break down at 4 a.m. on one of the coldest
nights in Iowa; it was -17, with a -30 wind chill. I remember hearing
about Service Legends from commercials/radio, and they didn't charge
extra for 24-hour service. The initial repairmen found out my blower went
& that my furnace had been leaking carbon monoxide! For the next 2 days,
everyone I worked with at Service Legends lived completely up to 100% of
all their guarantees and everything they offered on their website.
Friendly employees, excellent service and prompt attention to all my
needs! They made sure I made it through the night and let me borrow 2
space heaters. Service Legends helped make a potentially life-
threatening situation very bearable! Since I live in a mobile home, I
was quite limited in choices of furnaces. But my salesman assured me
that this model will be more energy efficient as well. I am extremely
satisfied with the excellent customer service at Service Legends!

I am very pleased with North Central Services, Minot, ND. They arrived
in a matter of a couple hours after being called. They checked the furnace, decided it could not be repaired and needed to be replaced, and were
there the next day to install a new one. They were willing to work
with me on a payment plan. They have very courteous and polite service people. The installer recommended this brand so that is what I went with. The options for a mobile home are not that great, but I am very happy with

Very satisfied with the purchase. Easy to install, with no modifications
required to the home or furnace. Just be aware that your house will have
a smell as the oil on the heat exchanger burns off.

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 their
customer service go?

Piece of crap
Purchased this furnace with a/c in September of 2011 and have had to
have the blower motor replaced four times in four months. Don't buy this
unit..it is a lemon.

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 their 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!

Jan 2009 We replaced 20 Year Mobile Furnace with a Coleman
DGAA077BDTB..(same model of furnace someone else is Very
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
