Gas Furnace Repair in Spokane, WA

A gas furnace is the most common heating system in American homes — and when it fails, the cause is almost always one of a handful of well-known problems that an experienced technician can diagnose and fix in a single visit. Our certified gas furnace repair technicians carry the most common parts on every truck, give you upfront pricing before touching anything, and back every repair with a 90-day guarantee. Whether your furnace won't ignite, is blowing cold air, making strange sounds, or cycling on and off constantly — we find the problem fast and fix it right.

Common Gas Furnace Problems We Fix

1. Pilot Light or Igniter Failure
The igniter or pilot light is the most frequently replaced gas furnace component. When it fails, your furnace tries to start but never produces heat. You may hear the system click repeatedly but feel no warmth from your vents.

Signs:
→ Furnace runs but no heat comes out.
→ Clicking sound at startup with no ignition.
→ Pilot light won't stay lit.

Fix:
Igniter replacement or pilot light cleaning and adjustment, most completed same day.

2. Cracked Heat Exchanger
A cracked heat exchanger is the most serious gas furnace problem, and the most dangerous. The heat exchanger separates combustion gases from your breathing air. When it cracks, carbon monoxide can leak directly into your home without any warning smell.

Signs:
→ CO detector alarm going off.
→ Yellow or flickering burner flame.
→ Headaches, nausea, or dizziness at home that go away when you leave.
→ Visible cracks or stress marks on the heat exchanger.

Fix:
Heat exchanger replacement or full furnace replacement depending on age and severity. We always give you honest options — never pressure you toward unnecessary replacement.

3. Faulty Gas Valve
The gas valve controls the flow of gas to your burners. A faulty valve can prevent your furnace from starting, cause intermittent heating, or in rare cases allow gas to flow when it should not — which is a safety issue requiring immediate attention.

Signs:
→ Furnace won't turn on at all.
→ Inconsistent heating, works sometimes, fails other times.
→ Gas smell near the furnace unit.

Fix:
Gas valve testing and replacement by a licensed technician. Never attempt to work on a gas valve yourself.

4. Dirty or Clogged Burners
Over time, dust, rust, and debris accumulate in burner assemblies. Dirty burners produce an uneven, inefficient flame — reducing heat output, increasing gas bills, and causing the furnace to run longer than it should to reach your set temperature.

Signs:
→ Yellow, orange, or uneven burner flame.
→ Rising gas bills without increased usage.
→ Furnace runs constantly but house stays cold.

Fix:
Burner cleaning, adjustment, and combustion analysis restores full efficiency in one visit.

5. Flame Sensor Failure
The flame sensor confirms that your burners have ignited before allowing gas to continue flowing. When it gets dirty or fails, your furnace starts, runs for a few seconds, then shuts off, a pattern called short cycling.

Signs:
→ Furnace starts then shuts off after 2–3 seconds
→ Repeated on-off cycling
→ Error code on digital thermostat

Fix:
Flame sensor cleaning or replacement, one of the quickest and most affordable gas furnace repairs.

6. Draft Inducer Motor Failure
The draft inducer motor vents combustion gases safely out of your home before ignition begins. When it fails, the furnace will not start at all as a built-in safety measure.

Signs:
→ Furnace won't start, no sounds at all.
→ Humming or grinding noise at startup.
→ Error code indicating pressure switch fault.

Fix:
Draft inducer motor replacement, typically completed same day with parts on truck.

Gas Furnace Repair vs. Replacement

One of the most common questions we hear:
"Should I repair my gas furnace or replace it?"

Here is the honest answer:
Repair is almost always the better choice when:
→ Your furnace is under 15 years old.
→ The repair cost is less than 50% of a new unit.
→ The heat exchanger is intact.
→ The rest of the system is in good condition.

Replacement makes more sense when:
→ Your furnace is over 15–20 years old.
→ Repairs are needed repeatedly year after year.
→ The heat exchanger is cracked.
→ Energy bills are climbing despite repairs.

Our technicians will always give you an honest assessment — not a push toward the more expensive option. We explain exactly what is wrong, what it will cost to fix, and what a replacement would cost so you can make the right decision for your home and budget.

Gas Furnace Safety — What You Should Know
Gas furnaces are safe when properly maintained, but they require respect for the risks involved. Here is what every homeowner should know:

Carbon Monoxide:
CO is colorless, odorless, and potentially fatal. Install CO detectors on every floor and near your furnace. If your detector alarms, leave immediately and call emergency services.

Gas Leaks:
If you smell gas near your furnace, do not use any switches, do not use your phone inside, leave immediately, and call your gas company from outside.

Annual Maintenance:
The single best thing you can do for gas furnace safety is schedule an annual inspection before each winter. Our technicians check heat exchanger integrity, combustion quality, gas pressure, and CO levels on every maintenance visit.
