Heating & Cooling

Furnaces, air conditioners, heat pumps, sizing, efficiency, lifespan, and repair-vs-replace decisions.

How long does a furnace last in Utah?

A well-maintained gas furnace in Utah typically lasts 15-20 years, with 80% AFUE models averaging 18 years and 96% AFUE condensing models averaging 15-17 years due to condensate-related component wear.

How do I know if my furnace is dying?

The biggest warning signs are a yellow or flickering burner flame (should be steady blue), uneven heat between rooms, short-cycling, rising gas bills without a usage change, strange banging/rumbling noises, and visible rust or scale on the heat exchanger.

Should I repair or replace my furnace?

If the repair quote exceeds 50% of a new furnace AND the unit is over 12 years old, replacement is almost always cheaper over a 5-year horizon. Under 8 years old, repair. In between, it depends on the specific part and efficiency rating.

What's the best furnace efficiency rating for Utah?

For most Utah homes, a 96% AFUE two-stage or modulating furnace is the best long-term choice — the higher efficiency pays back within 8-10 years on Wasatch Front winter gas bills, and staging prevents the hot/cold cycling that single-stage 80% units cause.

How often should I change my furnace filter?

1-inch pleated filters: every 1-3 months. 4-inch or 5-inch media cabinets: every 6-12 months. Homes with pets, construction dust, or wildfire smoke: the short end of each range.

Do I need a heat pump in Utah?

Heat pumps make sense in Utah if you're replacing both the AC and furnace at once, if you have solar, or if you want to decarbonize. Cold-climate heat pumps now work effectively down to -15°F, and the best solution for most Utah homes is a dual-fuel system (heat pump + gas furnace backup).

How do I size an air conditioner for my home?

A Manual J load calculation is the only correct way. Rule-of-thumb 'one ton per 500-600 sqft' oversizes most Utah homes by 20-40% because it ignores insulation, window orientation, shading, and air-sealing improvements newer homes already have.

Water Quality

Hardness, softeners, reverse osmosis, whole-home filtration, and Utah's well-known water profile.
