Consequences of Not Changing a Dirty AC Air Filter

Air conditioners generally don’t require very much maintenance, but there are a few things you must do to keep them in good condition—namely, changing their filter. Forgetting to check and change your air conditioner’s filter can be easy, but penciling this task into your quarterly home maintenance routine is essential. If you don’t, you may start to experience these negative consequences of not changing a dirty AC filter.

Decreased Efficiency

One of the many negative effects of not changing your air conditioner’s filter is reduced efficiency. If the air filter gets clogged, it won’t be able to flow cool air through your home as easily. As a result, the system will have to work harder to push the cool air past the barrier of dust and debris. In doing so, the system will consume more energy, which decreases the efficiency of the unit and increases your monthly energy bills.

Premature Wear and Tear

Another consequence of not changing a dirty AC filter is the premature wear and tear that will likely occur to the system. As we previously stated, when the AC filter gets clogged, the system will have to work harder to push the cooled air through. Such extra exertion places a larger amount of strain on the AC system’s motors than they were designed to withstand. As a result, the system will begin to undergo premature wear and tear that may cause it to break down more quickly. To avoid having to purchase and install an entirely new air conditioner, it’s best to take the time to change or clean its filter on a regular basis.

Reduced Comfort

Despite working harder and consuming more energy, an air conditioner won’t be very effective at cooling your home if its filter is clogged. When the AC filter gets backed up, it blocks cooled air from flowing out of it. Thus, your space will likely become uncomfortably warm while you pay extra on your energy bill to keep the space cool. If you notice some of the rooms in your home are warmer than others, you should take a look at your AC system’s filters to make sure they aren’t clogged. There’s a good chance dust bunnies are to blame.
