An air conditioning unit's filters, coils, and fins need routine upkeep for the unit to work effectively and effectively throughout its years of service. Overlooking essential upkeep guarantees a steady decrease in air conditioning performance while energy use progressively increases. Have a look at our Energy Saver 101 Infographic: Home Cooling for more ways to help improve your convenience and the effectiveness of your air conditioning system.
Air Conditioner Filters
The most important upkeep job that will ensure the efficiency of your ac system is to routinely replace or clean its filters. Clogged, filthy filters block typical air flow and lower a system's effectiveness considerably. With normal air flow obstructed, air that bypasses the filter may carry dirt straight into the evaporator coil and hinder the coil's heat-absorbing capability. Replacing a dirty, clogged up filter with a tidy one can decrease your a/c's energy intake by 5% to 15%.
For central air conditioners, filters are typically located somewhere along the return duct's length. Typical filter places remain in walls, ceilings, heating systems, or in the air conditioner itself. Room air conditioning system have a filter installed in the grill that faces into the space.
Some types of filters are reusable; others should be replaced. They are readily available in a variety of types and performances. Clean or replace your cooling system's filter or filters every month or more during the cooling season. Filters may require more frequent attention if the a/c unit is in continuous use, service air condition undergoes dusty conditions, or you have fur-bearing pets in your home.
The a/c unit's evaporator coil and condenser coil gather dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still gather dirt. This dirt lowers airflow and insulates the coil, decreasing its capability to take in heat. To prevent this issue, examine your evaporator coil every year and tidy it as necessary.
Outside condenser coils can also end up being really dirty if the outdoor environment is dusty or if there is foliage close by. You can quickly see the condenser coil and notice if dirt is gathering on its fins.
You need to minimize dirt and debris near the condenser system. Your clothes dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning up the area around the coil, eliminating any particles, and cutting foliage back at least 2 feet (0.6 meters) permit adequate airflow around the condenser.
The aluminum fins on evaporator and condenser coils are easily bent and can obstruct air flow through the coil. Air conditioning wholesalers sell a tool called a "fin comb" that will comb these fins back into almost original condition.
Occasionally pass a stiff wire through the system's drain channels. Obstructed 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, examine the seal between the a/c and the window frame to guarantee it reaches the unit's metal case. Wetness can harm this seal, permitting cool air to escape from your home.
Getting ready for Winter season
In the winter, either cover your room air conditioner or eliminate and store it. Covering the outdoor system of a central air conditioning conditioner will protect the system from winter season weather condition and debris.
Employing a Professional
When your air conditioning system requires more than routine maintenance, hire a professional service specialist. A trained service technician will find and repair problems in your a/c system.
The specialist needs to:
Check for right amount of refrigerant
Test for refrigerant leaks utilizing a leak detector
Record any refrigerant that needs to be left from the system, rather of illegally releasing it to the atmosphere
Look for and seal duct leakage in central systems
Step airflow through the evaporator coil
Confirm the proper electric control sequence and make sure that the heating unit and cooling system can not operate concurrently
Inspect electric terminals, clean and tighten connections, and apply a non-conductive finish if necessary
Oil motors and check belts for tightness and wear
Examine the accuracy of the thermostat.
