No matter what climate you live in, the clogged air filter in the HVAC system is a major problem. Here in Orange County, our heating systems don’t put in a huge amount of work, but you’ve probably had yours running regularly over the last few weeks when night and morning temperatures dropped into the high 40s. You’ll likely have reason to turn the AC on again before the winter is over—that’s just how our climate works.
No matter if you have the air conditioner, the heater, or just the central fan of the HVAC system running, you’ll need to pay attention to the HVAC filter and have it changed routinely to avoid having it become clogged. This is a basic part of HVAC maintenance in Irvine, CA—one of the few parts of maintenance you can do on your own. We recommend checking on the filter once a month. You’ll know it’s too clogged if you hold it up to the light and the filter blocks out the light. Expect to change the filter every one to three months.
