An air conditioner’s filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

To keep your system in good condition, continue reading for useful tips on properly maintaining your HVAC system.

1. REPLACE FILTERS

Replace your filters every 90 days for better efficiency. If you use your unit more than normal or if your unit is older, your filter may need to be changed more often. A good way to judge if your filter needs replacing is if it is covered in dust and air can no longer flow.

Don’t settle for cheap filters. This is one area that can cost you down the line. Air filters have come a long way and there are new and improved products on the market. Air filters are easy to change by slipping out the old filter and then sliding in the new one.

2. CLEAN THE CONDENSATE DRAIN LINE

Your HVAC system has a condensate drain line. If this line becomes clogged, it can cause your system to freeze and fail to operate properly. Cleaning the line is another quick fix. Simply detach the line and pour a cup of bleach or vinegar to clean out the sediment algae, and mold that can build-up.

3. KEEP YOUR EVAPORATOR AND CONDENSER COILS CLEAN

Both your indoor and outdoor HVAC units have coil systems. It is important that these coils remain free of debris for consistent airflow to keep the units running. One sign of blocked coils is the unit may no longer turn on. Cleaning the coils is another quick HVAC maintenance hack. Be careful and follow the coil cleaner instructions. If the coils become damaged it can be a costly repair.

4. CHECK AIR DUCTS DURING HVAC MAINTENANCE

This is a simple maintenance procedure. With the unit running, walk through the house to ensure that air is flowing through the vents. If you do not feel the air coming through, make sure the vents are fully open and not being obstructed. It is also a good idea not to close too many vents. The more vents you close the harder the unit will have to work.

5. CHECK FOR TEARS IN AIR DUCTS

Sometimes critters can get into your attic and damage your air ducts. If you feel air is being restricted, check for damage. A sign of torn ducts is insulation debris blowing through your vents.
