Frequently Asked Questions about Furnace Repair

Is your furnace acting up? Get answers to common questions about furnace repair and find trusted local technicians.

How often should I change my furnace filter?

It's recommended to change your furnace filter every 1-3 months, or more often if you have pets, allergies, or live in a dusty area. A clean furnace filter improves indoor air quality and keeps your system running efficiently. A clogged filter makes your furnace work harder, wasting energy and shortening its lifespan.

What is the difference between a single-stage and two-stage furnace?

Single-stage and two-stage furnaces have operational differences.
Single-stage furnaces operate at only one output level – full capacity. This can lead to temperature fluctuations and higher energy bills because the furnace is either running at its maximum setting or completely off..
Two-stage furnaces offer two levels of heat output: a lower setting for mild weather and a higher setting for colder temperatures. This allows the furnace to modulate its output based on the actual heating demand, resulting in more consistent temperatures, quieter operation, and improved energy efficiency.Two-stage furnaces provide enhanced home comfort and energy savings compared to single-stage models.

How do I reset my furnace?

Before calling for repairs, consider resetting your furnace. Here's how to reset most furnaces:
  1. Turn off the furnace: Set the thermostat to the 'off' position.
  2. Turn off the power: Locate the circuit breaker for your furnace and switch it off.
  3. Wait: Wait at least 30 seconds, though longer is sometimes recommended for the system to reset.
  4. Turn the power back on: Flip the circuit breaker back to the 'on' position.
  5. Turn on the furnace: Turn the thermostat back on and set it to your desired temperature.
If the problem continues after the reset, it's best to call a qualified HVAC technician for diagnosis and repair..

Why is my furnace making strange noises?

Unusual sounds from your furnace can indicate a variety of problems, from minor issues to major malfunctions. :
  • Banging or popping: Could be due to a buildup of sediment in the heat exchanger.
  • Squealing or screeching: Often a sign of a problem with the blower motor or the inducer motor.
  • Rumbling or vibrating: Check for loose parts or components.
  • Clicking: Could be caused by a faulty igniter, control board, or other electrical components. If the clicking sound is persistent, it is best to contact an HVAC technician.
  • Whining: Similar to squealing or screeching, this indicates an issue with a motor.
If your furnace is making unusual sounds, it is best to have the system inspected. Ignoring unusual sounds can lead to further damage or costly repairs down the road.
