- Combustion analysis verifies heat exchanger integrity — the #1 safety check.
Spokane furnace failures cluster in two weeks: the first cold snap in November, and the deep-freeze week in January. The furnace that breaks then was the furnace that needed service in October. Annual maintenance cuts your no-heat emergency risk by ~70% and extends equipment life by 3–5 years.
Our furnace service visit isn’t a 20-minute filter-swap. We run a 32-point inspection including combustion analysis, full electrical check, blower amp-draw, igniter condition, and duct leakage. You get a written report with photos of anything we found.
What’s included
Every furnace service visit covers:
32-point inspection
Combustion, electrical, blower, igniter, flame sensor, pressure switch, inducer, condensate drain, vent piping, thermostat calibration, gas pressure, return air temperature, supply temperature rise.
Combustion analysis
O₂, CO, CO₂, efficiency, draft, and stack temperature measured against manufacturer spec. We catch cracked heat exchangers before they’re a safety issue.
Blower motor service
Amp-draw test, capacitor test, belt service, bearing lubrication (where applicable), and motor mount inspection.
Igniter & flame sensor service
Hot surface igniter resistance check, flame sensor microamp reading, cleaning where appropriate. OEM-spec parts only.
Condensate drain flush
High-efficiency furnaces produce acidic condensate that corrodes drains and pans. We flush, treat, and verify float switch operation.
Written report with photos
You get a PDF with the inspection findings, any safety concerns, and recommended repairs prioritized by urgency.
When to call
Signs you need furnace service now
Some signs mean you should call today, not next week. Catch them early and you save the equipment.
- 01
Annual pre-winter tune-up
Schedule September–November for best availability. Maintenance-plan members get auto-scheduled visits.
- 02
Furnace is 5+ years old and never serviced
Even new furnaces benefit from year-one service — we catch factory defects and warranty issues early.
- 03
Yellow flame, soot, or strange smell
Combustion issue. Don’t wait — call now.
- 04
Higher than normal gas bill
Often a slow efficiency loss from a dirty burner, failing igniter, or cracked heat exchanger. The tune-up pays for itself in year one.
- 05
Furnace makes new noises
Squeal, bang, rattle, hum — each points to a specific component. Cheap fix now; expensive compressor/blower replacement later.

Furnace Service questions
Furnace Service FAQ
Modern gas furnaces have a 15–20 year expected life with annual service, 10–12 years without. The maintenance cost is $189–$229/year; the difference is one full equipment replacement ($5,800–$14,400). The math is straightforward.
Two visits per year (fall furnace, spring AC), priority dispatch for emergencies, 2-year workmanship warranty on all repairs, no after-hours surcharge, 15% discount on parts, and waived diagnostic fee. Plans start at $229/year.

Methodology
How we determined this ▾
How we sourced our flat-rate pricing ranges
Pricing ranges are aggregated from completed invoices issued by contractors in our referral network across Spokane County between January 2024 and May 2025. Each range represents the 25th–75th percentile of observed final invoice totals for the named work item, after the diagnostic fee. Outlier invoices (under $200 or over $25,000) are excluded. Ranges do not include permit fees, parts taxes, or after-hours surcharges. Your technician writes the actual quote after on-site diagnosis.

Terms we use on this page ▾
- AFUE
- Annual Fuel Utilization Efficiency. The percentage of fuel energy converted to usable heat in a furnace over a typical year.
- A 96% AFUE gas furnace wastes 4% of fuel energy, mostly as vented exhaust. Modern condensing furnaces in Washington must be 95% AFUE or higher. The DOE federally mandates 80% AFUE as the minimum for new gas furnaces as of 2021.
- Source: DOE 10 CFR 430
- NATE certification
- North American Technician Excellence. An independent certification for HVAC technicians, with separate exams in air conditioning, heat pumps, gas furnaces, and air distribution.
- NATE-certified techs pass proctored exams on installation, service, and diagnostics. We require NATE certification for every lead technician we refer. Washington State doesn’t require NATE, but it’s the de facto industry standard for competency.
