Frequently Asked Questions about Furnace Repair

Is your furnace acting up? 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 at least quarterly, or more often if you have pets, allergies, or live in a high-pollution area. Regularly replacing filters is simple and helps prevent many furnace problems. 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 can lead to 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 know when it's time to replace my furnace?

Here are signs that your furnace is nearing the end of its lifespan and may need replacing::
  • Age: If your furnace is 15-20 years old or older, it's likely time to consider a replacement.
  • Frequent Repairs: Repeated service calls can mean underlying problems.
  • High Energy Bills: A noticeable increase in your heating bills might be caused by an inefficient furnace.
  • Uneven Temperatures: If some rooms in your house are colder than others, it could be a sign of problems with your furnace or air distribution.
  • Strange Noises: Unusual or loud sounds can signal problems with the blower motor, igniter, or other components..
  • Yellow or Flickering Burner Flame: A healthy furnace flame should be blue. A yellow or flickering flame can indicate a variety of issues. This should be addressed right away.
  • Dry or Dusty Air: An old furnace can contribute to dry, dusty indoor air. A new furnace with improved filtration can help alleviate this problem.
If you're experiencing any of these signs, it's advisable to consult with an HVAC professional for a furnace inspection and assessment.

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 continues after the reset, don't attempt to diagnose or repair the issue yourself.

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. Regularly replacing filters is simple and helps prevent many furnace problems. 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 know when it's time to replace my furnace?

Here are signs that your furnace is nearing the end of its lifespan and may need replacing::
  • Age: If your furnace is 15-20 years old or older, it's likely time to consider a replacement.
  • Frequent Repairs: Repeated service calls can mean underlying problems.
  • High Energy Bills: A spike in your heating bills might be caused by an inefficient furnace.
  • Uneven Temperatures: If you have cold spots, it could be a sign of problems with your furnace or air distribution.
  • Strange Noises: Banging, squealing, or rumbling noises can signal problems with the blower motor, igniter, or other components..
  • Yellow or Flickering Burner Flame: A healthy furnace flame should be blue. A yellow or flickering flame can indicate a problem with the burners, insufficient airflow, or a dangerous carbon monoxide leak. This should be addressed right away.
  • Dry or Dusty Air: An old furnace can contribute to dry, dusty indoor air. Upgrading your system can improve comfort and IAQ.
Don't ignore potential furnace problems.

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 continues after the reset, it's best to call a qualified HVAC technician for diagnosis and repair..
