Heating & Furnace Services in Boise, Idaho

Furnace Repair and Heating Service in Boise

Think of a single-story home on the Central Bench on the first cold morning in the third week of October, right around the date Boise averages its first freeze. The thermostat calls for heat, the furnace in the hall closet lights, runs for a minute, shuts itself off, then tries again. By the fourth cycle the house is still 58 degrees. The unit was in the house when the owners bought it and has never had a tune-up, and nobody knows whether the problem is a dirty flame sensor or the start of a much bigger bill.

Boise winters are long rather than brutal. The airport record shows about 108 nights a year at or below 32 F, a January low that averages 25.5 F, and about 16 days a year when the high never gets above freezing, for roughly 5,320 heating degree days. The all-time low is minus 28 from 1888, and minus 25 from December 1990 in the airport era. A furnace in Boise runs most days from the first freeze around October 17 to the last one around May 1.

That climate also answers the heat pump question. An average January low in the mid 20s, with less than one day a year at or below zero, is a climate where a properly sized heat pump carries most of the winter and a furnace or electric backup covers the coldest nights. We install both and size either one to the house rather than to a sales target.

Replacing a furnace inside Boise city limits takes a mechanical permit from the City of Boise Planning and Development Services Building Division, which says plainly that mechanical permits are required for replacing furnaces and for adding, replacing or relocating ducts and registers. The city inspects the fuel gas pressure test, rough-in and final. In the East End, some homes are heated by geothermal water from the Boise Warm Springs Water District instead of a furnace at all.

Furnace repair in Boise starts with a diagnosis, not a replacement pitch. If a flame sensor, igniter or control board failed, we fix that part. If the heat exchanger is cracked or the unit is worn out, we show you and put a replacement price in writing. We service all major brands and answer seven days a week, 7am to 5pm.
