What is a furnace tune-up?

• Inspecting and cleaning the burners
• Checking the heat exchanger for cracks or leaks
• Inspecting the blower motor and fan
• Checking the flue pipe for proper venting
• Testing the safety controls
• Lubricating moving parts
• Checking refrigerant levels (for heat pumps)
• Testing for carbon monoxide leaks

Annual tune-ups maximize the life and efficiency of your furnace.

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

What is an AFUE rating?

AFUE stands for Annual Fuel Utilization Efficiency. It is a measure of how effectively a furnace converts fuel to heat. . It's a percentage reflecting how much of the energy in the fuel becomes heat for your space. For instance, a furnace with a 95% AFUE rating converts 95% of the fuel's energy into usable heat, and only 5% is wasted. Always choose a furnace with the highest AFUE rating you can afford. The minimum AFUE rating for new furnaces is 80%, but high-efficiency models can have AFUE ratings of 90% to 98% or more.

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: Multiple repairs, especially costly ones, suggest it's more economical to invest in a new, more reliable unit..
• High Energy Bills: A spike in your heating bills could mean 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 problem with the burners, insufficient airflow, or a dangerous carbon monoxide leak. If you notice a yellow flame, contact an HVAC technician immediately..
• Dry or Dusty Air: An old furnace may cause dry, dusty indoor air. Upgrading your system can improve comfort and IAQ.

If you're experiencing any of these signs, it's advisable to consult with an HVAC professional for a furnace inspection and assessment.
