A little regular upkeep can go a long way. Here are some things to be aware of that can help improve your comfort and the efficiency of your air conditioner.

Change or clean the air filters

The most important maintenance task that will improve the efficiency of your air conditioner is to routinely replace or clean the air filters. Replace one-inch pleated filters once a month. If you’re unsure of the type of filter to use, you can reference your existing filter size before ordering. Or your local service technician can help you to determine filter size, type, and location. Remember, filters may need more frequent attention if your air conditioner is in constant use, is subject to overly dusty conditions, or you have pets in the house.

Clean the air conditioner’s coils

The air conditioner's evaporator and condenser coils collect dirt over time. This dirt reduces airflow and insulates the coil, reducing its ability to transfer heat. Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if plant debris is allowed to collect. An annual cleaning of your indoor evaporator coils and outdoor condenser coils by a local service technician can ensure your system achieves top performance.

Remove debris from around the Condenser (Outdoor unit)

Over time, things like leaves, dirt, and grass clippings will build up on the outside of the outdoor portion, or condenser, of your air conditioner, decreasing system capacity and reducing airflow. You should trim any shrubs or other plants back from around the condenser and remove any accumulations impeding airflow to and from the unit.

Straighten coil fins

The aluminum fins on the evaporator and condenser coils are easily bent and can block airflow through the coil. Your local service technician can check these on an annual visit to avoid any issues.
