Air Conditioning Servicing & Maintenance

Air conditioning is often treated as fit-and-forget, but like any mechanical system it loses efficiency and reliability without regular attention. A neglected system uses more electricity, cools less effectively, and is far more likely to fail at the worst possible moment — typically the hottest week of the year. Regular servicing is also frequently a condition of keeping a manufacturer’s warranty valid.

What’s included in a typical service

Filter inspection, cleaning or replacement

Checking refrigerant pressure and topping up if there’s a detected leak

Cleaning indoor and outdoor coils

Checking drainage to prevent water leaks or mould growth

Inspecting electrical connections and controls

Testing overall system performance against specification

How often should a system be serviced?

Most domestic systems benefit from an annual service, ideally in spring before the cooling season starts. Commercial systems, particularly those running long hours or in demanding environments (kitchens, server rooms, retail units with high footfall), often need servicing twice a year, and larger commercial systems above certain refrigerant charge thresholds have statutory leak-checking obligations under F-Gas regulations regardless of how “fine” the system seems to be running.

Maintenance contracts for commercial clients

Rather than booking each service individually, many commercial and landlord clients set up a planned maintenance contract — scheduled visits, priority callout in the event of a breakdown, and documented compliance records for building/facilities management purposes. This is worth asking about directly if you manage more than one site or a building with tenants.

Signs a service is overdue

Reduced cooling performance, unusual noise, water pooling near the indoor unit, higher-than-usual energy bills, or a musty smell when the system runs are all common indicators.
