An ac system's filters, coils, and fins need routine upkeep for the unit to work efficiently and efficiently throughout its years of service. Disregarding essential upkeep makes sure a stable decline in cooling performance while energy use progressively increases. Have a look at our Energy Saver 101 Infographic: House Cooling for more ways to help enhance your convenience and the effectiveness of your air conditioning system.

Air Conditioning System Filters

The most essential maintenance task that will ensure the performance of your a/c is to consistently replace or clean its filters. Blocked, filthy filters block normal air flow and reduce a system's performance significantly. With normal airflow blocked, air that bypasses the filter might bring dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a filthy, stopped up filter with a tidy one can lower your ac system's energy consumption by 5% to 15%.

For central air conditioners, filters are generally located someplace along the return duct's length. Typical filter areas remain in walls, ceilings, heaters, or in the air conditioner itself. Room a/c unit have a filter installed in the grill that faces into the space.

Some kinds of filters are reusable; others should be changed. They are offered in a variety of types and effectiveness. Clean or change your air conditioning system's filter or filters on a monthly basis or two throughout the cooling season. Filters may need more regular attention if the air conditioner is in constant use, goes through dirty conditions, or you have fur-bearing pets in your home.

Ac System Coils

The air conditioning unit's evaporator coil and condenser coil gather dirt over their months and years of service. A clean filter avoids the evaporator coil from staining quickly. In time, however, the evaporator coil will still gather dirt. This dirt lowers airflow and insulates the coil, lowering its SERVICE AIR CONDITION ΑΘΗΝΑ capability to soak up heat. To avoid this problem, examine your evaporator coil every year and tidy it as needed.

Outside condenser coils can likewise end up being really filthy if service air condition the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notification if dirt is collecting on its fins.

You should minimize dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all prospective sources of dirt and debris. Cleaning up the area around the coil, removing any particles, and trimming foliage back at least 2 feet (0.6 meters) allow for adequate air flow around the condenser.

Coil Fins

The aluminum fins on evaporator and condenser coils are easily bent and can obstruct air flow through the coil. Air conditioning wholesalers offer a tool called a "fin comb" that will comb these fins back into nearly original condition.

Condensate Drains pipes

Periodically pass a stiff wire through the unit's drain channels. Clogged drain channels prevent a system from decreasing humidity, and the resulting excess wetness may tarnish walls or carpet.

Window Seals for Space Air Conditioners

At the start of each cooling season, inspect the seal in between the a/c and the window frame to guarantee it makes contact with the system's metal case. Wetness can damage this seal, enabling cool air to leave from your home.

Preparing for Winter season

In the winter, either cover your room ac system or remove and keep it. Covering the outside unit of a central air conditioning conditioner will safeguard the system from winter weather and particles.

Employing a Professional

When your air conditioning system requires more than regular maintenance, employ an expert service technician. A trained technician will find and fix problems in your a/c system.


The specialist should:

Look for correct amount of refrigerant

Test for refrigerant leakages utilizing a leakage detector

Capture any refrigerant that should be evacuated from the system, rather of unlawfully launching it to the atmosphere

Look for and seal duct leak in central systems

Procedure airflow through the evaporator coil

Validate the appropriate electrical control sequence and ensure that the heater and cooling system can not operate at the same time

Examine electric terminals, tidy and tighten connections, and use a non-conductive finishing if required

Oil motors and inspect belts for tightness and wear

Check the accuracy of the thermostat.
