Frequently Asked Heating Questions

[bc_accordion] [bc_card title=”What’s the difference between a furnace and a heat pump?”]

Furnaces generate heat by combusting a fuel source, while heat pumps move heat using electricity. Both systems circulate warm air throughout the home using a blower and ductwork.

[/bc_card] [bc_card title=”How often should I change my HVAC air filter?”]

The general recommendation is to check the air filter every 30 days, changing it when it appears dirty, or every 90 days, whichever comes first. You may need to follow a different schedule depending on the type of filter you use and whether you have allergies or pets.

[/bc_card] [bc_card title=”When is it time to replace my furnace?”]

Consider replacing your furnace if any of the following is true:

  • The unit is more than 15 years old.
  • Breakdowns are becoming more frequent.
  • An upcoming repair approaches 50% of the replacement cost.
  • Your energy bills are climbing.
  • You have widespread home comfort problems.
[/bc_card] [bc_card title=”What does AFUE mean?”]

AFUE stands for annual fuel utilization efficiency. The closer this number is to 100, the better the furnace is at converting fuel into usable heat. Look for an AFUE rating of 85 or higher when replacing your furnace.
