Home air conditioning maintenance
By Airva Editorial Team · Reviewed by Airva Technical Review · Updated 13 July 2026
A little maintenance keeps home air conditioning running efficiently, quietly and reliably. Neglected systems cost more to run and are more likely to fail on the hottest days.
What you can do
- Clean or check the indoor filters regularly — dust reduces airflow and efficiency.
- Keep the outdoor unit clear of leaves and debris so it can breathe.
- Notice changes — new noises, weaker output or odours are worth a service.
What a professional service covers
A periodic professional service typically includes filter and coil cleaning, refrigerant and electrical checks, drainage checks, and confirming the system runs correctly. Work involving refrigerant must be carried out by suitably qualified (F-gas) engineers — a capability we check when matching you with an installer.
Planning a new system? A reversible unit still benefits from the same upkeep. See the installation process, or request an installer match.
