It’s Probably Time to Check Your Furnace Filter

When was the last time you checked your furnace filter? If you can’t remember (or it’s been more than 30 days), it’s definitely time to head to your mechanical room and make sure it’s not clogged.

To protect the furnace and ensure healthy indoor air, we always recommend homeowners check filters monthly and replace them as needed. Operating a furnace with a dirty filter can strain the whole system (decreasing efficiency) and allow dust and debris to circulate throughout the home, aggravating respiratory and breathing issues.

Furnace Filter Tips:

  • Incorporate filter maintenance as part of your monthly routine. Many homeowners find it helpful to check the filter on the first or last day of the month.
  • When you do replace the filter, write the date on it. That way, you won’t have to try and remember when it was last replaced.
  • Make sure to correctly install the filter. Find the arrows and ensure that they are pointing toward the furnace and away from the return duct.
  • Always choose the right type of filter for your system and make sure to have a backup supply at home.
  • Safety first! Always turn off the power to the furnace before checking and changing the filter.

Checking and changing the furnace filter is usually not at the top of a homeowner’s mind, but it’s an incredibly important maintenance task. Many furnace problems and indoor air quality issues are a result of a clogged furnace.
