Why service your air conditioning?
Like any mechanical system, air conditioning performs best when it is properly maintained. Regular servicing keeps the unit running at peak efficiency, reduces energy bills, extends the lifespan of the system and ensures small problems are caught before they become expensive breakdowns.
How often is a service needed?
For most residential split systems, an annual service is sufficient — typically in spring before the cooling season begins. Properties that use air conditioning heavily, or commercial premises where the system runs year-round, may benefit from servicing twice per year: once in spring for cooling season and once in autumn for heating mode.
Some manufacturers specify minimum service intervals in their warranty terms — check your documentation if the system is still under guarantee, as failing to service it may invalidate the warranty.
What does an air conditioning service include?
A thorough annual service by a qualified F-Gas engineer typically covers:
- Cleaning and checking the indoor unit's air filter and coil
- Checking refrigerant levels and inspecting for leaks
- Cleaning the outdoor unit's coil and checking the fan
- Checking electrical connections and control board
- Testing heating and cooling modes and checking temperature differential
- Checking condensate drain is clear (to prevent water leaks)
- Checking and cleaning the outdoor unit's coil fins
Can I do any maintenance myself?
Yes — cleaning the air filter every 4–6 weeks during heavy use is something any owner can and should do. It takes five minutes, improves efficiency noticeably and significantly reduces the load on the system. Wipe down the indoor unit casing and check that the outdoor unit is free of debris too. Anything involving refrigerant or electrical components must be carried out by a certified engineer.
