Overview of the DGAH

The Coleman DGAH is a discontinued multi-speed gas furnace with an efficiency rating of 80% AFUE. It was a downflow furnace designed for use in manufactured and mobile housing. It used natural gas and could be easily converted to LP gas during installation without requiring extra parts. The unit featured an aluminized steel heat exchanger which provided efficient operation while resisting corrosion. Two air filters were installed on the top door where they could be easily checked and replaced, and the unit's cabinet featured a durable scratch-resistant finish.

"Coleman heater for mobile home"
This heater is the best and is recommended for use in a mobile home for its safety rating. It is the only heater approved in California. It heats fast and is a real energy saver. It also very quiet. It makes me feel safe with it in my home because of the construction visible to me. I recommend it to any home owner that needs a new unit for the fire safety of this unit.

"Coleman & EVCON Furnace, No Thanks."
My Coleman, (evcon), Furnace Model # dgah056bbsa, (45,000 btu), is less than three years old and the electric fan motor is already making noise. I had to replace the "Glow" stick in August of '08, this year. I cost me $150.00. Now the motor is making noise when it first starts up. It sounds like the bearing is going out. The service Tech who replaced the glow stick also installed the furnace. He said that the motor is expensive I'll never buy another Coleman Furnace for my Mobil Home again. I can't even find the correct filters for it. I have to cut ones from the store to fit it. What a joke!
