How often should I replace my hvac system?

According to the Department of Energy, HVAC system should be replaced every 10 to 15 years. Why? After about 10 years internal parts of your HVAC system begin to deteriorate. This can differ depending upon maintenance, type of HVAC system installed, and regular upkeep of other materials, such as your air filter.

How often should I replace my Air Filter?

Typically, you'll want to replace your furance's air filter every 90 days or so. This leads to cleaner air quality and increases the longevity of your furnace. Furnaces need clean air filters so they don't overwork due to the dust and other pollutants that pack up on the filter. Of course, this is also dependant upon the MERV rating of your air filter. When purchasing an annual HVAC Maintenance Plan with us, we'll inspect your air filter and will let you know when it should be replaced.
