AC Maintenance: 7 Tips That Extend Its Life and Cut Your Bill

An air conditioner is like any other machine: small, regular care saves you expensive repairs later. These are the points we recommend to our customers most often.

1. Clean the filters regularly

This is the most important and the easiest step. A dusty filter blocks airflow, so the unit works harder, draws more power and cools less. In summer with daily use, clean them every two to four weeks.

2. Get a full service at least once a year

A full service covers the indoor unit, the outdoor unit and the pipework. The best timing is just before summer starts, so the unit enters the season at full efficiency.

3. Do not switch it on and off repeatedly

Every cold start draws a very high current. If you are coming back to the room within half an hour, leaving it running is better than switching it off and on.

4. Set the temperature to 24-25 degrees

Every degree lower raises consumption noticeably. Setting it to 16 does not cool the room any faster — that is a common myth. It just keeps the unit running longer.

5. Make sure the outdoor unit can breathe

The outdoor unit needs air moving around it. Do not stack things in front of it or cover it, and if it sits in direct sun all day, a shade is worth adding — while still leaving space for ventilation.

6. Close windows and doors

Obvious, but often forgotten. Any air leak keeps the unit running without ever reaching your set temperature.

7. Signs you need a technician now

• The unit runs but no longer cools like it used to.
• Water dripping from the indoor unit.
• Unusual noises or excessive vibration.
• A bad smell when it starts up.
• The unit keeps cutting out on its own.

Do not put these off: a small issue such as a refrigerant leak can end up destroying the compressor, which is the most expensive part of the system.
