A furnace that quits in January cannot wait. Summit Heating & Air repairs gas furnaces, heat pumps, electric furnaces, and wall heaters throughout Boise and Boise, Meridian, Nampa, Eagle, and Kuna. Our technicians diagnose the whole system, from the thermostat to the flue, and explain what they found in plain terms. You approve a written price before the repair begins. Common winter failures include ignitors, flame sensors, pressure switches, inducer motors, and blower motors. We carry those parts on the truck. We also test heat exchangers on every furnace call, because a cracked exchanger can leak combustion gases into the house. If we find one, we show you the evidence and shut the unit down until it is fixed or replaced. Summit Heating & Air is licensed under ID license HVAC-C-12345 and has worked on Treasure Valley furnaces for 15 years.
Signs your furnace or heat pump needs repair
- Cold air from the vents while the thermostat calls for heat
- The furnace clicks or tries to light but never fires
- Short bursts of heat followed by the system shutting off
- A burning or sulfur smell that lasts more than a few minutes
- A heat pump running constantly with lukewarm air in the house
- Your carbon monoxide alarm sounds, even briefly, while the furnace runs
What a heating repair visit covers
- Thermostat, wiring, and control board test
- Ignition system check: ignitor, flame sensor, gas valve, and pressure switch
- Heat exchanger inspection with a combustion analyzer and carbon monoxide test
- Blower motor, inducer motor, and capacitor inspection
- Flue, condensate drain, and filter check
- Written repair price and a clear repair-or-replace conversation if needed
How heating repair works with us
- You call (208) 555-0142, we ask a few questions to sort out urgency, and we book the next available window.
- The technician runs the furnace through a full cycle and tests each stage of the ignition sequence.
- You see the reading or the failed part, and you approve a written price before we proceed.
- We complete the repair, verify combustion and carbon monoxide levels, and confirm the heat exchanger is sound.
- You receive a summary of the visit and any recommended follow-up, with no pressure to act on it that day.
Heating repair pricing in Boise
Heating diagnostics start from $89, which includes the safety inspection and a written price for the repair. The fee is credited toward the work if you go ahead. Cost depends on the part, how hard it is to reach, and whether it is a standard part or a brand-specific board or motor. Flame sensors and ignitors sit at the low end. Inducer motors, variable-speed blowers, and control boards cost more. We quote per job rather than per hour. Heat pump repairs follow the same structure. If a repair exceeds what the furnace is worth, we tell you and quote a replacement so you can compare.
Why heating repair matters in Boise
Boise winters bring weeks of lows in the teens and twenties, and the valley inversions in December and January can hold cold air in place for days. A furnace runs long hours in that stretch, and weak parts fail under the load. Older homes in the North End and on the Bench often still run furnaces from the 1990s, sometimes in basements with original venting. Newer homes in Meridian often have high-efficiency condensing furnaces whose drain lines can freeze if they run through an unheated garage or crawl space. Kuna has the same issue in its newer subdivisions. Boise's 2,700-foot elevation also calls for a gas input adjustment on many furnaces, and a unit set up for sea level can short cycle or soot up.
Questions we get about this
My furnace turns on and off every few minutes. What is wrong?
Short cycling usually points to a dirty filter, a failing flame sensor, an overheating limit switch, or an oversized furnace. Check the filter first. If it is clean and the problem continues, call us. Repeated overheating can damage the heat exchanger over time.
Is it safe to keep running my furnace if it smells?
A brief dusty smell on the first cold day is normal. A gas smell, a burning electrical smell, or a carbon monoxide alarm is not. Shut the system off, open windows, leave the house if the alarm sounds, and call your gas utility first and then us.
Do you repair heat pumps in heating mode?
Yes. We service heat pumps year round, including defrost board faults, reversing valve problems, and auxiliary heat issues. Boise heat pumps rely on backup heat during cold snaps, so we confirm the backup stage works during every heating visit.
What does a heat exchanger inspection involve?
We inspect the exchanger visually where possible, then run the furnace with a combustion analyzer on the flue and a carbon monoxide meter in the supply air. A cracked exchanger is a safety issue, and we do not leave a furnace running with one.
How old is too old to repair a furnace?
Most gas furnaces last 15 to 20 years. Past that, a repair over several hundred dollars is worth weighing against replacement, especially with rising parts costs for older models. We give you both numbers on the same visit and let you choose.
Do you service Intermountain Gas customers and propane furnaces?
We service natural gas furnaces on Intermountain Gas and propane furnaces in the rural areas outside Kuna. Propane furnaces need a conversion kit and different orifices, so tell us the fuel type when you book and we will bring the right parts.
