An aircon that is serviced regularly cools better, uses less electricity and lasts longer. Skipping services is one of the most common reasons units fail in the middle of a Gauteng summer.
How often to service
- Homes: at least once a year, ideally before summer.
- Offices and shops: every 6 months, because units run longer hours.
- Server rooms, restaurants and industrial sites: every 3 months, or as the manufacturer recommends.
What a proper service includes
- Cleaning or replacing filters.
- Cleaning the indoor coil and the outdoor condenser.
- Checking the gas pressure and looking for leaks.
- Clearing the drain line so water does not leak inside.
- Checking electrical connections, the remote and the thermostat.
Warning signs
- Weak airflow or the room never gets cold.
- Water dripping from the indoor unit.
- Strange noises or bad smells.
- Higher electricity bills than usual.
Installing a new unit?
Correct sizing matters. A unit that is too small runs all day, and one that is too big cycles on and off. We size, supply and install all aircon brands for homes and businesses.
