14 Businesses Doing a Great Job at ΕΠΙΣΚΕΥΗ AIR CONDITION

An air conditioning system's filters, coils, and fins need routine upkeep for the system to function successfully and effectively throughout its years of service. Neglecting required upkeep makes sure a steady decrease in a/c efficiency while energy usage steadily increases. Take a look at our Energy Saver 101 Infographic: House Cooling for more ways to help enhance your convenience and the performance of your air conditioning system.

Air Conditioner Filters

The most crucial upkeep job that will make sure the performance of your air conditioning unit is to consistently change or clean its filters. Obstructed, filthy filters obstruct typical airflow and lower a system's effectiveness substantially. With typical airflow obstructed, air that bypasses the filter may bring dirt straight into the evaporator coil and hinder the coil's heat-absorbing capability. Changing an unclean, clogged up filter with a clean one can decrease your a/c's energy intake by 5% to 15%.

For central air conditioning conditioners, filters are normally located somewhere along the return duct's length. episkevi klimatistikon Common filter locations remain in walls, ceilings, heaters, or in the air conditioner itself. Space air conditioning unit have a filter installed in the grill that deals with into the room.

Some types of filters are multiple-use; others should be changed. They are readily available in a variety of types and effectiveness. Clean or change your cooling system's filter or filters every month or two during the cooling season. Filters might need more regular attention if the ac system remains in consistent use, goes through dusty conditions, or you have fur-bearing family pets in your home.

A/c Unit Coils

The a/c unit's evaporator coil and condenser coil gather dirt over their months and years of service. A tidy filter avoids the evaporator coil from staining rapidly. In time, however, the evaporator coil will still gather dirt. This dirt decreases air flow and insulates the coil, lowering its ability to soak up heat. To avoid this issue, inspect your evaporator coil every year and tidy it as essential.


Outdoor condenser coils can likewise become really dirty if the outdoor environment is dirty or if there is foliage nearby. You can easily see the condenser coil and notification if dirt is collecting on its fins.

You must decrease 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, getting rid of any debris, and trimming foliage back a minimum of 2 feet (0.6 meters) allow for adequate air flow around the condenser.

Coil Fins

The aluminum fins on evaporator and condenser coils are quickly bent and can block airflow through the coil. Cooling wholesalers sell a tool called a "fin comb" that will comb these fins back into nearly initial condition.

Condensate Drains pipes

Sometimes pass a stiff wire through the system's drain channels. Blocked drain channels prevent a system from reducing humidity, and the resulting excess moisture may 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 unit and the window frame to ensure it makes contact with the unit's metal case. Wetness can harm this seal, enabling cool air to escape from your home.

Preparing for Winter

In the winter, either cover your room air conditioning unit or eliminate and store it. Covering the outside system of a central air conditioner will secure the system from winter season weather condition and particles.

Working with a Professional

When your air conditioner needs more than regular upkeep, employ an expert service specialist. A trained specialist will find and fix issues in your cooling system.

The specialist must:

Check for right amount of refrigerant

Test for refrigerant leaks using a leak detector

Catch any refrigerant that should be evacuated from the system, rather of unlawfully releasing it to the environment

Check for and seal duct leak in central systems

Step air flow through the evaporator coil

Validate the right electrical control series and make certain that the heating unit and cooling system can not operate concurrently

Examine electrical terminals, clean and tighten connections, and apply a non-conductive finishing if necessary

Oil motors and check belts for tightness and wear

Check the precision of the thermostat.
