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. Check your filter monthly and change it as needed.

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 temperature fluctuations and higher energy bills because the temperature fluctuates more than with two-stage furnaces.
Two-stage furnaces can run at both low and high speed. 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. A two-stage furnace may be a more expensive initial investment, but it can provide greater comfort and savings over time.

How do I reset my furnace?

If your furnace isn't working correctly, a simple reset can sometimes resolve the issue. 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 a few minutes 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 persists after the reset, don't attempt to diagnose or repair the issue yourself.

Why is my furnace making strange noises?

Strange noises from your furnace can indicate a variety of problems, from minor issues to major malfunctions. :
  • Banging or popping: Could be due to dirty burners, delayed ignition, or expanding ducts.
  • Squealing or screeching: Often indicates an issue with the blower motor or other moving parts.
  • Rumbling or vibrating: Check for loose parts or components.
  • Clicking: Could be caused by a faulty igniter, control board, or other electrical components. Electrical issues can be hazardous, so contact a professional.
  • Whining: Similar to squealing or screeching, this indicates an issue with a motor.

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 operate at only one output level – full capacity. This may cause uneven heating and fluctuating bills because the temperature fluctuates more than with two-stage furnaces.
Two-stage furnaces can run at both low and high speed. 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. A two-stage furnace may be a more expensive initial investment, but it can provide greater comfort and savings over time.
