Frequently Asked Questions about Furnace Repair

Having problems with your heating system? Get answers to common questions about furnace repair so you can make informed decisions.

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 high-pollution 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 differ in their heating output capabilities:
Single-stage furnaces have only one setting, they either operate at 100% or are off. This may cause uneven heating and fluctuating 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. They work by running at a lower speed most of the time and switching to high speed when necessary.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 fully power down.
  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 persists after the reset, don't attempt to diagnose or repair the issue yourself.
