An ac system's filters, coils, and fins need routine upkeep for the system to operate efficiently and effectively throughout its years of service. Disregarding needed maintenance ensures a constant decline in cooling performance while energy usage progressively increases. Take a look at our Energy Saver 101 Infographic: Home Cooling for more methods to assist improve your convenience and the effectiveness of your ac system.
A/c Unit Filters
The most crucial maintenance task that will make sure the efficiency of your air conditioning unit is to consistently change or clean its filters. Clogged, filthy filters block typical airflow and lower a system's effectiveness considerably. With normal airflow obstructed, air that bypasses the filter may bring dirt directly into the evaporator coil and hinder the coil's heat-absorbing capacity. Replacing a dirty, blocked filter with a tidy one can reduce your a/c's energy usage by 5% to 15%.
For central air conditioners, filters are generally located someplace along the return duct's length. Common filter places remain in walls, ceilings, furnaces, or in the air conditioner itself. Room air conditioners have a filter mounted in the grill that deals with into the space.
Some kinds of filters are episkevi klimatistikon athina multiple-use; others need to be changed. They are available in a variety of types and efficiencies. Tidy or replace your a/c system's filter or filters each month or 2 throughout the cooling season. Filters may need more frequent attention if the a/c remains in continuous usage, undergoes dirty conditions, or you have fur-bearing animals in your house.
Air Conditioning Unit 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 soiling rapidly. In time, nevertheless, the evaporator coil will still collect dirt. This dirt lowers air flow and insulates the coil, minimizing its ability to soak up heat. To prevent this problem, inspect your evaporator coil every year and tidy it as necessary.
Outside condenser coils can also end up being really filthy if 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 need to decrease dirt and particles near the condenser system. Your dryer vents, falling leaves, and mower are all prospective sources of dirt and particles. Cleaning up the area around the coil, eliminating any debris, and cutting foliage back a minimum of 2 feet (0.6 meters) enable appropriate air flow around the condenser.
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 almost initial condition.
Condensate Drains pipes
Sometimes pass a stiff wire through the unit's drain channels. Blocked drain channels prevent a system from lowering humidity, and the resulting excess wetness might discolor walls or carpet.
Window Seals for Room Air Conditioners
At the start of each cooling season, check the seal in between the ac system and the window frame to ensure it makes contact with the system's metal case. Wetness can damage this seal, permitting cool air to leave from your house.
Preparing for Winter
In the winter, either cover your room air conditioning unit or eliminate and store it. Covering the outside unit of a central air conditioning conditioner will secure the system from winter weather condition and debris.
Working with an Expert
When your air conditioner needs more than routine upkeep, employ an expert service professional. A well-trained specialist will find and repair problems in your air conditioning system.
The technician should:
Check for appropriate quantity of refrigerant
Test for refrigerant leaks using a leak detector
Catch any refrigerant that must be left from the system, rather of illegally releasing it to the environment
Check for and seal duct leakage in main systems
Procedure air flow through the evaporator coil
Verify the correct electric control series and ensure that the heating unit and cooling system can not operate simultaneously
Inspect electrical terminals, clean and tighten connections, and apply a non-conductive finish if needed
Oil motors and examine belts for tightness and wear
Examine the precision of the thermostat.
