HVAC Maintenance

An air conditioning system require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary hvac maintenance will ensure a steady decline in air conditioning performance while energy use steadily increases.

​The most important maintenance task for a homeowner to do that will ensure the efficiency of the air conditioner is to routinely replace or clean its filters. Clogged or dirty filters reduce the amount of airflow and significantly reduce the system's efficiency. In addition, when airflow is obstructed, air can bypass the filter and deposit dirt directly into the evaporator coil and  impair the coil's heat-absorbing capacity. Replacing a dirty or clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.

Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system's filter or filters as often as necessary during the cooling and heating season.

​The air conditioner's evaporator coil and condenser coil collect dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary.

Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins.

You should minimize dirt and debris near the outdoor condensing unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet to allow for adequate airflow around the condenser.

​When your air conditioner needs more than regular maintenance, such as when it does not reduce the indoor temperature to a comfortable level, hire a professional service technician. A well-trained technician will find and fix problems in your air conditioning system.

Celsius A/C & Heating's annual 24-point inspection and maintenance tune-up service is designed to keep your hvac system running in optimal condition year-round. Our technicians will address any problems that your AC unit may have before they can affect the other components of your HVAC system.
