Regular preventive maintenance is an essential step in improving the performance of your air conditioning system. In addition to regularly changing your filters and cleaning the ducts, you also need to undertake other major maintenance tasks at least once or twice a year. A well-maintained unit not only lasts longer but also guarantees cool air when you need it most. With this in mind, here are the four main maintenance tasks you should conduct every year for optimal AC performance.

Inspect the Electrical Components

An air conditioner has various electrical parts such as the wiring and connections, compressor, fan, capacitors, and controls such as the thermostat. These parts need to function correctly for the AC to work. When problems such as loose connections, overheating, water damage, or wear and tear occur, they can affect the performance of the entire unit. Therefore, perform tune-ups at least once or twice a year, paying attention to the electrical parts of the unit. Repair or replace any worn or damaged components to boost AC performance.

Check the Mechanical Parts

Your AC has various moving parts that contribute to the overall functioning of the system. These include the compressor, evaporator and condenser coils, and a fan. If one part isn't working, the rest won't be efficient. For example, if the fan isn't working, the warm air coming from your home to the outdoor unit won't be cooled. Since most of these parts are located outside, you need to inspect them regularly and clear the area around the outdoor unit to prevent debris from interfering with their functions.

Inspect the Unit's Ductwork

If you're using a ducted air conditioning system, you need to conduct annual checks on your ductwork. Ducts are primarily responsible for supplying conditioned air to the entire house. If they are dirty, they will circulate poor quality air, especially if your filters are worn. If the ducts are leaking, they will lose cool air and affect the efficiency of your unit. In addition to cleaning the ducts, inspect them, and look for signs of leaks.

Refill AC Refrigerant

The refrigerant or coolant is the heart of your air conditioning system. It absorbs heat from the air, releases it outdoors through the help of the outdoor components, and circulates cool air in your home. If the refrigerant levels are low due to leaks or damage to the compressor, your house won't cool efficiently. Thus, you need to check the refrigerant levels at least twice a year. If the fluid is low, get a refill.

These four maintenance tasks will enhance the performance and durability of your AC. Always work with an HVAC contractor for air conditioning maintenance services, professional tune-ups, and repairs!
