Which furnace is best for my mobile home?

Posted in: 

Q: I have a single wide mobile home 14x80 with 4" walls and vinyl siding. The furnace (2000 Coleman 56,000 BTU) is old, runs constantly, and is costing too much to heat my home (in rural Minnesota). Will a Nordyne (Maytag label) 90,000 BTU 80% efficient furnace be a good choice?

A: That should be plenty for your home. Even a 70,000 BTU would suffice.

The big different in a mobile home is duct work. I use the saying, "It doesn't matter how strong your water pump is if you have a bad water hose." Make sure you check the duct work underneath.

The larger BTU furnace will deliver more heat. It will kick on, heat the home, and then kick off. It will save money to burn more gas for a short while than to run almost constantly.
