An a/c's filters, coils, and fins require routine upkeep for the system to operate efficiently and effectively throughout its years of service. Ignoring essential maintenance guarantees a consistent decline in air conditioning performance while energy usage steadily increases. Take a look at our Energy Saver 101 Infographic: House Cooling for more methods to assist enhance your comfort and the effectiveness of your air conditioning system.

Air Conditioning Unit Filters

The most crucial maintenance task that will guarantee the efficiency of your a/c unit is to regularly replace or clean its filters. Blocked, unclean filters obstruct regular air flow and minimize a system's efficiency significantly. With regular air flow blocked, air that bypasses the filter may carry dirt straight into the evaporator coil and impair the coil's heat-absorbing capability. Changing an unclean, clogged filter ΕΠΙΣΚΕΥΗ ΚΛΙΜΑΤΙΣΤΙΚΩΝ with a clean one can decrease your ac system's energy intake by 5% to 15%.


For central air conditioners, filters are usually situated someplace along the return duct's length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself. Room air conditioners have a filter installed in the grill that deals with into the room.

Some kinds of filters are reusable; others must be replaced. They are offered in a range of types and performances. Clean or change your a/c system's filter or filters on a monthly basis or two throughout the cooling season. Filters might require more frequent attention if the a/c unit is in continuous use, is subjected to dirty conditions, or you have fur-bearing pets in the house.

Air Conditioning System Coils

The a/c's evaporator coil and condenser coil collect dirt over their months and years of service. A tidy filter avoids the evaporator coil from soiling quickly. In time, nevertheless, the evaporator coil will still collect dirt. This dirt reduces air flow and insulates the coil, minimizing its capability to soak up heat. To prevent this problem, examine your evaporator coil every year and clean it as needed.

Outdoor condenser coils can likewise become extremely filthy if the outside environment is dirty or if there is foliage close by. You can quickly see the condenser coil and notification if dirt is collecting on its fins.

You should minimize dirt and debris near the condenser system. Your dryer vents, falling leaves, and mower are all prospective sources of dirt and debris. Cleaning up the area around the coil, removing any debris, and cutting foliage back a minimum of 2 feet (0.6 meters) permit appropriate airflow around the condenser.

Coil Fins

The aluminum fins on evaporator and condenser coils are quickly bent and can block air flow through the coil. Air conditioning wholesalers offer a tool called a "fin comb" SERVICE ΚΛΙΜΑΤΙΣΤΙΚΩΝ ΑΘΗΝΑ that will comb these fins back into almost initial condition.

Condensate Drains

Sometimes pass a stiff wire through the unit's drain channels. Blocked drain channels prevent a system from lowering humidity, and the resulting excess moisture might tarnish walls or carpet.

Window Seals for Space Air Conditioners

At the start of each cooling season, check the seal in between the air conditioning system and the window frame to guarantee it reaches the unit's metal case. Wetness can harm this seal, allowing cool air to escape from your home.

Preparing for Winter season

In the winter season, either cover your space ac system or get rid of and keep it. Covering the outside unit of a central air conditioner will protect the system from winter season weather condition and debris.

Working with a Professional

When your air conditioning system needs more than regular maintenance, hire an expert service technician. A well-trained service technician will discover and fix issues in your a/c system.

The specialist must:

Look for proper quantity of refrigerant

Test for refrigerant leakages utilizing a leak detector

Catch any refrigerant that must be left from the system, instead of unlawfully launching it to the atmosphere

Look for and seal duct leakage in central systems

Step airflow through the evaporator coil

Confirm the right electrical control series and make sure that the heating system and cooling system can not run concurrently

Inspect electrical terminals, tidy and tighten connections, and use a non-conductive finishing if necessary

Oil motors and examine belts for tightness and wear

Examine the precision of the thermostat.
