Indoor Air Quality Maintenance
The easiest thing a homeowner can do to protect and maintain their homes comfort/indoor air quality system, is to replace the air filter, or clean the air filter, but it is also the most neglected. Dirt, pollen, and other particulate matter is the number one issue with poor indoor air quality and the major cause of breakdowns and loss of efficiency in a comfort system. There is no system that does not require care, and just as you would not neglect the maintenance on your daily driver, the same goes for your homes comfort system.
The best practice is to schedule a routine to replace filters either monthly or as required, to ensure that you eliminate any unnecessary expense due to preventable service visits. As equipment continues to gain in efficiency they are more and more susceptible to this dirt and debris, due to the increased operational safety parameters, safety devices and construction.
