How Often Should You Clean Your A/C?

Why A/C cleaning matters

A dirty air conditioner has to work harder to move air and cool the room. The compressor runs longer, uses more electricity and wears out faster. Dust and mould inside the unit are also blown into the room every time you switch it on, which can affect breathing and cause bad smells. Cleaning is one of the cheapest ways to protect an expensive appliance.

Signs your A/C needs cleaning

Common warning signs include:

• Weak airflow even at full fan speed
• A musty or sour smell when the unit starts
• Ice forming on the indoor coil
• Water dripping from the indoor unit
• Higher electricity bills without any other change at home

Dust, smell and weak airflow

The most obvious sign is dust. Open the front panel and check the plastic filters — if they look grey and clogged, they need cleaning. Bad smells usually mean mould inside the coil or drain line. Weak airflow points to either a very dirty filter or, more seriously, a dirty coil that needs a full deep clean.

How often to clean it

For homes in Limassol we recommend cleaning filters every 2 to 4 weeks during peak use, and booking a professional deep clean at least once a year. Homes with pets, homes near the sea or units used year-round often need a deep clean every 6 to 9 months. Offices and rental apartments should be on a fixed schedule to avoid tenant complaints.
