Sundance asks a lot out of a furnace

Homes here need heat from September through June, ten months out of the year. On winter nights that average 12°F, a furnace runs long hours to keep up, night after night, for most of the year.

A new furnace has to be sized for that kind of cold from the start. If it burns gas and was built after November 2015, federal rules already set the floor at 80 percent AFUE, but the number on the unit only matters if the install is right. The wrong size shows itself fast once the temperature drops and stays down.

What size furnace does my house need?
The right size comes from a load calculation, not a square footage chart. A contractor measures your walls, windows, ceiling height, and how much air leaks in and out, then sizes the furnace to match. With heat needed here from September through June and winter nights averaging 12°F, a furnace that's too small will run constantly and still fall behind on the coldest nights. One that's too big cycles on and off fast and wears out sooner. Have a contractor run the calculation rather than go by the old unit's size or the house's age.
How do I know it's time to replace my furnace?
Watch for rooms that won't heat evenly, a furnace that runs longer than it used to, or repair bills that keep coming back. If a repair is going to cost close to what a new furnace would run, that's usually the point to stop patching it. Heat is needed here September through June, so a furnace on its way out has ten months a year to fail on you, not just the coldest week. A contractor can tell you whether what's wrong is worth fixing or a sign the furnace is done.
Is a high-efficiency furnace worth it?
It depends on how much you run your furnace and how long you plan to stay in the house. Every furnace made since November 2015 has to hit at least 80 percent AFUE, so the real question is whether to go higher than that baseline. With heat needed here 10 months a year, a furnace that runs that much has more chances to make up the difference in fuel used than one that only runs a few months elsewhere. A contractor can walk through the options for your house and price out what each one would take to install.
