Servicing & maintenance

Scheduled cleaning and checks that keep units efficient, keep the air clean and catch small faults before they become breakdowns.

An air conditioner that has not been serviced keeps running, just not well. Dust on the coils and filters makes it work harder for less cooling, and blocked drains are the usual cause of water dripping from indoor units.

Coastal conditions add salt and moisture to the mix, which speeds up corrosion on outdoor coils and connections. Regular servicing is the cheapest way to protect the system and your electricity bill.

The parts a service reaches. Dust on filters and coils, and slime in the drain, are what make units weaker, smellier and drippier over time.

What's included

Filter and coil cleaning
Indoor filters, evaporator and outdoor condenser coils cleaned to restore airflow and heat transfer.
Drain clearing
Condensate trays and lines flushed to stop leaks, odours and mould.
Refrigerant checks
Operating pressures and temperatures checked against the manufacturer's specification.
Electrical inspection
Connections, capacitors and controls checked for wear, heat damage and corrosion.
Service report
A short written note of what was done and anything that needs attention.
Planned maintenance

How often should it be serviced?

General guidance. Dust, salt air and long running hours all shorten the interval.

Home, normal useSuggested interval: Once a year, before summer
Home close to the beach or harbourSuggested interval: Every six months
Offices and shopsSuggested interval: Every three to six months
Kitchens, server rooms, dusty or industrial sitesSuggested interval: Every three months
Cold rooms and display refrigerationSuggested interval: Every three months, plus regular coil and door-seal checks

Servicing questions

How often should an air conditioner be serviced?

For homes, at least once a year, ideally before summer. For businesses, busy shops and units close to the sea, every three to six months is more realistic.

Why is water dripping from my indoor unit?

Usually a blocked or poorly sloped condensate drain, or a dirty filter causing the coil to ice up and then thaw. Switch the unit off and book a service; it is normally a quick fix.

Due for a service? Book it before the heat does.
