Furnaces in Spokane Valley work harder than almost anywhere in Washington State. The combination of extreme cold winters, very dry air that generates static electricity damaging control boards, and the demands of continuous heating operation through months of serious cold puts every furnace component through more stress than a comparable unit in a mild climate. Older furnaces are generally more reliable than new ones — their mechanical simplicity means fewer electronic components to fail, and their parts are inexpensive and widely available. Modern high-efficiency furnaces are quieter and use less gas, but their variable-speed motors and complex electronics are expensive to repair when they fail.
What Actually Breaks in Spokane Valley Furnaces — From Most to Least Common
Igniter failure — by far the most common furnace repair in Spokane Valley. The hot surface igniter is a ceramic element that glows red-hot to ignite the gas burner. It weakens over time and eventually fails to reach ignition temperature. A furnace with a failing igniter may start inconsistently, take multiple tries, or not start at all. Igniter replacement is a straightforward same-day repair — we carry igniters for all major brands in our Spokane Valley service vehicles.
Flame sensor failure — the flame sensor is a metal rod that detects whether the burner actually lit after the igniter fires. When the sensor is coated with oxidation it cannot conduct the small current that tells the control board the flame is present — the board shuts off the gas as a safety measure. A furnace that starts, runs for 5-10 seconds, then shuts off and restarts repeatedly is almost always a dirty flame sensor. Cleaning or replacing the flame sensor is a same-day repair.
Temperature sensors and pressure switches — furnaces have multiple safety sensors that monitor temperature limits and combustion pressure. When any of these trip repeatedly, the furnace goes into lockout mode. These sensors protect against real problems — a tripping limit switch often means restricted airflow from a dirty filter, a blocked flue, or an overheating heat exchanger — and diagnosing the root cause matters as much as replacing the sensor.
Inducer motor failure — the inducer motor draws combustion gases through the heat exchanger and out the flue before the burner fires. It is required for operation and its failure stops the furnace entirely. Inducer motors fail from bearing wear and are a common repair on furnaces over 10 years old in Spokane Valley. The part cost varies — on older simpler furnaces, inducer motors are widely available and reasonably priced. On newer variable-speed systems, the cost is significantly higher.
Blower motor failure — the blower motor moves heated air from the heat exchanger through your ducts and throughout the home. The same motor runs during cooling season as well. On older furnaces, blower motors cost $100-$150 and are easy to source. On newer high-efficiency variable-speed systems, ECM blower motors can cost $400-$500 or more. This cost difference is a real consideration when weighing repair vs replacement on an aging furnace.
Control board failure — the furnace control board coordinates all ignition and safety functions. Boards fail from power surges, age, and in Spokane Valley, static electricity from the very dry winter air. Control board replacement costs vary significantly by brand and model. We diagnose control board failures accurately — a failing board mimics many other problems, and we verify the diagnosis before recommending replacement.
Heat exchanger failure — a cracked heat exchanger allows combustion gases to mix with the air circulating through your home. This is a safety issue, not just a comfort issue. We inspect heat exchangers with a camera during maintenance visits. A cracked heat exchanger typically means furnace replacement — the cost of replacing a heat exchanger on an aging furnace rarely makes financial sense compared to a new unit.
Ductwork issues — metal ductwork deteriorates over time depending on installation quality and use. Disconnected joints, corroded sections, and improper sealing reduce heating efficiency and can cause uneven temperatures throughout the home. We inspect accessible ductwork as part of our furnace service visits in Spokane Valley.
Furnace Maintenance in Spokane Valley
Annual fall maintenance before Spokane Valley’s heating season includes igniter inspection and testing, flame sensor cleaning, heat exchanger visual inspection, burner cleaning, inducer motor check, blower motor inspection, flue inspection, filter replacement, and thermostat calibration. This maintenance visit catches most of the failure modes above before they leave you without heat in January. We offer scheduled annual maintenance programs for Spokane Valley homeowners.
Furnace Installation in Spokane Valley
We hold contractor accounts with Ferguson and HVAC Direct at wholesale pricing below retail — we can often sell and install a new furnace for less than you would pay buying direct. Our licensed Spokane Valley technicians handle system selection, sizing, installation, permit filing through the City of Spokane Valley Permit Center, and inspection coordination. All installations include a full warranty. A Duct Leakage Affidavit may be required by the Washington State Energy Code for new installations — we handle this documentation as part of the permit process.

Frequently Asked Questions
Do you offer same-day furnace repair in Spokane Valley?
Yes. Furnace failures in Spokane Valley winter are emergencies — we prioritize same-day repair 6 days a week. Call as early as possible for fastest scheduling.
My furnace starts then shuts off after a few seconds — what is wrong?
Almost certainly a dirty or failed flame sensor. The burner lights but the sensor doesn’t detect the flame and shuts down gas as a safety measure. This cycle repeats. Flame sensor cleaning or replacement is a straightforward same-day repair in Spokane Valley.
My furnace won’t start at all — what are the most likely causes?
In order of likelihood for Spokane Valley: failed igniter, failed flame sensor putting the system in lockout, tripped limit switch from a dirty filter, failed inducer motor, or control board issue. Our technicians diagnose systematically — not by replacing parts randomly — so you get an accurate fixed quote for the actual problem.
Are new furnaces more expensive to repair than old ones in Spokane Valley?
Yes — significantly. Modern variable-speed furnaces have ECM blower motors that cost $400-$500+ versus $100-$150 on older units. Control boards on new systems are also more expensive and model-specific. Older furnaces have simple parts that are widely available and affordable. This is a real factor when deciding repair vs replacement on an aging furnace.
Does a furnace replacement in Spokane Valley require a permit?
Yes. Mechanical permits are required for furnace installation and replacement in Spokane Valley. Applications go through the City of Spokane Valley Permit Center — the online portal at spokanevalleywa.gov makes the process straightforward for like-for-like replacements.
