Frequently Asked Questions about Furnace Repair

What is a furnace tune-up?

A furnace tune-up is a preventative maintenance service performed by a qualified HVAC technician to ensure optimal performance, energy efficiency, and safety. A typical tune-up involves several checks and maintenance tasks, which often include:

• 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

A thorough tune-up can identify potential problems early on, preventing costly repairs and extending the lifespan 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 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 or if you encounter error codes, 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. . The AFUE rating is expressed as a percentage. For instance, a furnace with a 95% AFUE rating converts 95% of the fuel's energy into usable heat, while the remaining 5% is lost as exhaust gases.. Always choose a furnace with the highest AFUE rating you can afford. Look for high-efficiency systems for maximum savings.

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 less efficient and more prone to breakdowns.
• 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 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 variety of issues. This should be addressed right away.
• 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.
