UncategorizedHas Your AC Filter Been Checked Yet?


When was the last time you checked your AC filter? If it’s been a few months, it’s a good idea to take a look. Perhaps you’ve never even checked your AC filter or didn’t realize you should since it’s part of your regularly scheduled AC maintenance.

Whatever the case, it’s important to make sure your filter is clean. A dirty air filter can cause issues for your AC system and affect your home comfort. There’s a reason we always check your filter when we do maintenance on your system. If you’re wondering why your air filter is so important, we’ve included more information below.

The Role Your AC Filter Plays

Many people think their AC filter works to protect their home from dirty air, but that’s actually not true. Instead, the filter is meant to protect the internal parts of your air conditioner by keeping them free of dust and debris. If the filter becomes dirty and clogged, it can cause issues for the system overall.

The Consequence of “A Little Dirt”

We’ve all heard the phrase, “A little dirt never hurt anybody.” Unfortunately, this phrase does not apply to your air conditioner. Too much dirt on your AC filter can harm both your air conditioning system and your home comfort. Here are some issues that can arise when your air filter collects too much dirt:

  • Poor airflow: If your air filter is packed with dust and dirt, it only makes sense that it will alter the airflow. This will reduce the amount of cool air your system can create.
  • A dirty evaporator coil: Dirt in your filter won’t just remain in your filter. Eventually the dirt will end up in your system since there’s nowhere else for it to go. It will begin to collect on the evaporator coil, which can impact the cooling process.
  • An icy AC: Whether it’s a dirty filter, dirty evaporator coil, or both, these issues can lead to an icy air conditioner. When your air conditioner ices over, it can cause problems for the cooling process and damage the unit.

There’s only so much you can do for your AC system without a professional technician.
