What Happens When Your Air Conditioner Filter is Dirty?

If your air conditioner filter is dirty, it can cause a number of problems. A clogged filter forces the air conditioner to work harder to keep the house cool, leading to more frequent repairs and a shorter lifespan for the unit. Poor cold air flow in the air conditioning system is another consequence of a dirty filter, as the cold air will be trapped inside the air conditioner and cause ice to form on the coils. This can lead to an overheated air conditioner, uneven cooling throughout the house, and eventually a frozen system.

To prevent these issues, it's important to check your air filter regularly and clean or replace it when necessary. If your filter is reusable, you can rinse it in warm water and slide it back into the air conditioner. Advanced filters may last longer than a month, but we recommend checking them at least once a month. Not only will a dirty filter prevent your air conditioner from working properly, but it can also lead to costly repairs or a complete breakdown when you need your air conditioner most.

To keep your HVAC system running efficiently and avoid expensive repairs, make sure to check and clean your air filter regularly.
