How often should you service air conditioning?
A quick habit that keeps your system efficient, reliable and under warranty. Here's the UK guidance.
Air conditioning is low-maintenance, not no-maintenance. A short annual service protects the investment and keeps running costs down. Here's what you need to know.
How often?
- Home systems: once a year is ideal.
- Commercial / heavy use: every six months.
- Filters: a quick clean by you every few weeks during heavy use, between professional services.
What a professional service includes
- Cleaning and checking filters, coils and fins
- Checking refrigerant pressures and testing for leaks
- Clearing the condensate drain to prevent leaks and damp
- Inspecting electrical connections and controls
- Testing performance in both heating and cooling modes
Why it's worth it
Three reasons: efficiency (a clean, well-charged system uses less electricity), reliability (small faults get caught before they strand you in a heatwave), and warranty (most manufacturers require documented servicing to honour their guarantee).
There's also a legal angle: refrigerant handling is governed by F-Gas regulations, so top-ups and leak repairs must be done by a certified engineer. All ClimaTight servicing is F-Gas certified.
Signs your system needs attention now
Don't wait for the annual service if you notice weak airflow, warm air when it should be cold, unusual noises, water dripping indoors, or a musty smell. These are early warnings worth acting on.
Frequently asked questions
Can I service air conditioning myself?
You can clean the filters yourself — and should, regularly. But refrigerant checks, leak testing and electrical work must be done by an F-Gas certified engineer, both for safety and to keep your warranty valid.
What happens if I never service my air conditioning?
It gradually loses efficiency, costs more to run, and is more likely to fail — often in the middle of the hot spell when you need it most. You may also void the manufacturer's warranty.
