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 or if you encounter error codes, it's best to call a qualified HVAC technician for diagnosis and repair..

  • Maintenance: Regular maintenance significantly impacts the life of your furnace. A preventative maintenance plan can make your furnace more reliable.
  • Usage: Frequent or continuous use puts more strain on your system.
  • Quality: Higher-quality furnaces from reputable brands tend to last longer.
  • Proper Installation: Correct installation is key to longevity.
An older furnace may require more repairs and cost more to operate.

How can I tell if my furnace is the correct size for my home?

  • High Energy Bills: An incorrectly sized furnace can lead to increased energy consumption.
  • Inconsistent Temperatures: Noticeable temperature fluctuations throughout your home.
  • Short Cycling: If your furnace turns on and off frequently, it may not be heating your space efficiently and wasting energy.
  • Poor Air Quality: If the airflow from the vents seems weak or there are hot and cold spots, the unit may be the wrong size.
