An Air conditioning Units filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance will lead to a steady decline in air conditioning performance while increasing energy consumption.
AIR CONDITIONING FILTERS
The most important maintenance task that will ensure the efficiency of your air conditioning unit is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system’s efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.
For central air conditioning Units, filters are generally located somewhere 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 mounted in the grill that faces into the room.
Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system’s filter or filters every month or two during the summer. Filters may need more frequent attention if the air conditioner is in constant use or is subjected to dusty conditions, or you have fur-bearing pets in the house.
AIR CONDITIONING COILS
The air conditioner’s evaporator coil and condenser coil collect 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 collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary.
Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice 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 potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 600mm will allow for adequate airflow around the condenser.
The aluminium fins on evaporator and condenser coils are easily bent and can block airflow through the coil. Air conditioning wholesalers sell a tool called a “fin comb” that will comb these fins back into nearly original condition this is best carried out by a trained engineer. We at ThermoCool Solutions can do this on maintenance visits where required.
Occasionally pass a stiff wire through the unit’s drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolour walls or carpet. Thermocool Solutions have a high pressure air hose which we can use to move the blockages from the condensate drains should they require .
PREPARING FOR WINTER ENGINEER MAINTENANCE
In the winter, either cover your room air conditioner or remove and store it. Covering the outdoor unit of a central air conditioner will protect the unit from winter weather and debris.
When your air conditioning unit needs more than regular maintenance, We at ThermoCool Solutions can provide you with a highly skilled fully qualified engineer to install, repair and provide maintenance to the highest standard.
All our engineers will carry out the following:
• Check pressures for correct amount of refrigerant and optimum energy efficiency.
• Test for refrigerant leaks using a leak detector and leak detection fluid.
• Recover any refrigerant that must be evacuated from the system into a cylinder, instead of illegally releasing it to the atmosphere.
• Check for and seal duct leakage in central systems.
• Measure airflow through the evaporator coil using an anemometer.
• Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously by checking all safety devices.
• Inspect electrical terminals, clean and tighten connections, and apply a non-conductive coating if necessary.
• Oil motors and check belts for tightness and wear.
• Check the accuracy of the thermostat.
All of the above will ensure the correct running of your Refrigeration and Air Conditioning Systems providing you with the high energy efficiency and save you valuable money on the overall running costs of the units.
