Furnace Maintenance Tips Bought to You by CarrierIf you have a Carrier furnace, you’ve got the ultimate combination of energy efficiency and comfortable heating. What’s more, you’re making a worthwhile contribution to the health of our planet. However, if you notice that your furnace isn’t working at optimal levels and you neglect furnace maintenance, it could become damaged.

Proper care techniques and maintenance will extend the life of your Carrier furnace and reduce the risk of potentially expensive repairs. So, take the time to follow the simple furnace maintenance tips below:

  • Check the thermostat. Whenever you want your furnace to operate, the thermostat should be set to ‘heat’. Make sure you set the temperature higher than the current indoor temperature.
  • When you want your furnace to operate, keep all required power sources on. This includes the SSU switch (on the gray box), the circuit breaker and the power button on the furnace itself. This is essential for good furnace maintenance.
  • About once a month, replace the filter on your furnace. This is especially relevant for all 1” thick filters. If your furnace has a high-capacity pleated filter or a 2-inch thick filter, it should be replaced every other month.
  • Good furnace maintenance also includes preventing furniture and other large items from obstructing the return air grille. Also, all the air supply registers must be unobstructed while the furnace is running.

Note: When shopping for a furnace, consider the AFUE (annual fuel utilization efficiency) rating. This indicates the percentage of energy that’s converted to heat. The higher the AFUE rating, the more energy-efficient the furnace is – which means the more money you can save.
