Why Isn’t My Furnace Working Properly?
When the temperature drops in the Inland Northwest, your furnace works overtime. And like any hardworking machine, parts can wear out, breaks down or stop working the way they should.
Here are the home heating unit issues we see most often and how our NATE certified HVAC technicians typically fix them so your home stays warm and safe.
1. Thermostat Troubles
A lot of “no heat” calls end up being thermostat-related. Sometimes the thermostat can’t communicate with the furnace, or the temperature on the screen doesn’t match how the house actually feels. We check the wiring, recalibrate the thermostat, and replace faulty sensors or components when needed.
Most of the time, we can get everything running correctly the same day, without major heating repairs.
2. Ignition & Pilot Light Issues
If your furnace struggles to start, shuts down quickly, or fails to ignite altogether, the ignition system is usually the culprit. For older furnaces, it may be a pilot light problem. For newer systems, it might be a worn ignitor or dirty flame sensor.
We clean, adjust, or replace these components so your system can start up safely and reliably.
3. Blower Motor or Fan Problems
Weak airflow, strange noises, or no air movement at all often point to a blower motor issue. Our team checks the motor, bearings, belts, and electrical connections.
We repair or replace worn components and make sure the fan is pushing the right amount of warm air through your ducts.
4. Heat Exchanger Concerns (A Serious Safety Item)
A cracked or damaged heat exchanger can allow carbon monoxide to leak into your home, so this is something we take seriously. We inspect the exchanger, run a full combustion analysis, and explain your repair or replacement options based on safety standards and the overall condition of your furnace.
5. Ductwork Leaks & Airflow Imbalances
Even if your furnace is working perfectly, leaky or disconnected ductwork can make some rooms feel cold while others get too warm. We locate leaks, repair damaged sections, and ensure all connections are sealed properly to improve comfort and efficiency throughout your home.
6. Electrical Component Failures
Modern heating systems rely heavily on electrical parts like control boards, capacitors, sensors, and relays. When one of these fails, your furnace may short cycle, shut down unexpectedly, or refuse to start.
We use diagnostic tools to pinpoint the issue and replace the faulty components with quality, manufacturer-approved parts.
