user-7428907 | Posted in Energy, Heating & Insulation on

I’m looking for a recommendation for a forced air gas furnace with a good air exchanger.  We’re in Montana so we don’t need AC

    Most of the furnaces are about the same in reliability and function, this from over 30 years experience in HVAC.
    You definitely want a 90+% AFUE using outdoor combustion air.
    Some brands the replacement parts are very expensive.
    Personally I am currently using Goodman equipment, excellent equipment, warranty, ...
    Most problems with any brand equipment less than a few years old is installation related.
    As for the air exchanger not enough experience with to recommend.
