A professional air conditioning maintenance service should include
the work on:
- Air filters – cleaning. Clogged, dirty filters block air flow hence reducing the system’s efficiency. With larger commercial systems they may need to be replaced regularly.
- Evaporator and condenser coils – cleaning. Dirt builds up on these components responsible for absorbing the heat indoors and removing it to the outside air. Ensuring good airflow through coils fins – the aluminium fins are easily bent and may block paths for the air, it is fixed by ‘combing’.
- Refrigerant gas charge – testing for gas amount and for leaks using a leak detector. The gas serves as medium to carry heat and therefore its vital for proper operation. Any leaks depleting its amount will significantly reduce the system’s cooling and heating capabilities.
- Temperatures and pressures – testing.
- Condensate drainage – check for any blockages. Algae and dust can clog the thin draining pipe, leading to water dripping from the unit.
- Electrical connections – inspecting wiring, relays, contactors, cleaning and tightening where applicable. Checking voltage and amperage of the motors.
- Oiling up the motors, checking belts for tightness and wear.
- Checking accuracy and operation of the thermostat and the remote control.
Do you know that over 80% of mechanical failures are eliminated by regular maintenance?
Regular maintenance eliminates mechanical failures and provides safety in your house. Cleaning and checking your AC devices prevents molds and fungus that can lead to health problems. It is recommended for your devices to be checked by experienced specialists thoroughly and regularly.
Recommended maintenance frequency will depend on the type and size of the system, as well as its usage patterns. The rule of the thumb for most applications is at least once a year in the spring, and ideally every 6 months.
