What a nice upgrade! This old single stage furnace had some water damage and had to be taken out of service.

The new Amana furnace has a two stages of heat and a variable speed blower motor. We enhanced the air flow with a bigger air filter rack with a hinged door. Sealed filter racks keep the air healthier. The home is now safer, more efficient, and comfortable.
