Air Conditioner Filters
The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters reduce the amount of airflow and significantly reduce a system’s efficiency. Furthermore, if airflow is blocked, air may be able to bypass the filter and deposit dust onto the evaporator coils, which could cause them to become clogged and impair their ability to absorb heat. Replacing an old, dirty filter with a new one could save you up to 10 percent on your cooling bill.
Filters for central air conditioning systems are usually placed at some point along the system’s return ducts’ lengths. Filters usually come in one of three places: In walls, ceiling, or inside an AC unit. Air conditioning filters usually face towards the inside of the house so they don’t get dirty from dust particles floating through the air.
Some types of filters may need replacing after some time, whereas others may not require replacement at all. They are available in a variety of types and efficiencies. Replace or clean your AC unit’s filter regularly throughout the year. If the air conditioning unit has been running constantly for an extended period of time, filters may require more frequent cleaning than usual.
Air Conditioner Coils
Over time, the coils become clogged with dust from the outside environment. Cleaning filters prevent them from clogging up too soon. Eventually, the evaporator coils will continue collecting dust. Dirt blocks airflow, which decreases the coil’s 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. It’s easy to spot the condenser coil because it has fins sticking out from it. If there is dirt collecting on these fins, then they might be clogged up.
Minimize dust and debris near the air conditioner’s condensing unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. To ensure proper air flow, cleaning the area around the coil and removing any debris from the surrounding leaves allows for sufficient airflow around the condenser unit.
Hiring a Professional
If your air conditioning system requires more than routine maintenance, such as if it doesn’t keep the room at an appropriate temperature, call for help from a qualified HVAC repair company. A skilled technician will be able to spot any potential problems in an air conditioner immediately.
The technician must:
Check to see if there’s enough refrigerant in your system.
If there’s any refrigerant leaking out of the air conditioning unit, capture it before letting it go into the atmosphere.
Check for and seal duct leakage in central systems
Measure airflow through the evaporator coil
Make sure the correct electrical control sequence has been set up correctly and verify that the heating system and air conditioning systems cannot be operated at the same time.
Inspect electrical terminals for corrosion, clean them thoroughly, then carefully coat them with an insulator such as grease or silicone.
Check oil motor and belt tension.
Make sure the temperature setting matches reality.
