A little regular upkeep can go along way. So before you schedule a maintenance visit, 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, HVAC Dealer can recommend one based on your specific system. For all other filter sizes, HVAC Dealer will check, clean, or replace them at your annual maintenance visit. Remember, filters may need more frequent attention if your air conditioner is in constant use, is subject to dusty conditions, or you have pets in the house. Contact your HVAC Dealer to find out what frequency of filter change is right for your system.
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 absorb heat. Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. To avoid these problems, your HVAC Dealer will check and clean your air conditioner’s coils, if necessary, at your annual maintenance visit.
Remove debris from the unit
Over time, things like leaves, dirt and grass clippings will build up on the outside of your air conditioner, decreasing system capacity and reducing airflow. You should trim any shrubs or other plants back from around the air conditioner to keep from impeding airflow to and from the unit.
Straighten coil fins
The aluminium fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Your HVAC Dealer will check these pieces at your annual maintenance visit and straighten them, if necessary.
