7 Common Furnace Repairs to Keep You Warm This Winter

Dan Walsh • February 13, 2025

When winter’s chill sets in, a properly functioning furnace is essential for a comfortable home. While regular maintenance can prevent many issues, some repairs are more common than others. Here are 7 frequent furnace repairs that AAA Home Services often handles:

  1. Changing Filters

  2. Repairing Your Thermostat

    The thermostat controls your furnace, so any issues here can lead to heating problems. Common thermostat problems include incorrect settings, dead batteries, or a malfunctioning unit. AAA Home Services can diagnose and repair or replace your thermostat.

  3. Fixing the Starting Mechanism

    This includes issues with the igniter or pilot light. If your furnace won’t turn on, the starting mechanism is a likely culprit. AAA Home Services can safely diagnose and repair ignition problems.

  4. Fixing Blower Components

    The blower motor and fan circulate heated air throughout your home. A faulty blower motor can cause inconsistent heating or a complete lack of heat. AAA Home Services can repair or replace blower motors and other components.

  5. Fixing the Limit Switch

    The limit switch is a safety device that prevents the furnace from overheating. A malfunctioning limit switch can cause the furnace to shut down prematurely. AAA Home Services can address limit switch issues to ensure safe and reliable operation.

  6. Replacing the Heat Exchanger

    The heat exchanger is a critical component that transfers heat to the air. Cracks or damage to the heat exchanger can be dangerous, potentially leaking carbon monoxide. AAA Home Services can inspect and, if necessary, replace a faulty heat exchanger.

  7. Cleaning Dirty Ductwork

    Over time, dust and debris can accumulate in your ductwork, reducing airflow and indoor air quality.

Regular furnace maintenance, including annual inspections by AAA Home Services, can help prevent these common repairs and extend the life of your furnace. If you experience any issues with your furnace, don’t hesitate to contact AAA Home Services for expert diagnosis and repair.
