We service, clean and repair split systems and multi-head units — one engineer, one visit, and a written note of exactly what we found.
Most calls begin with one of these four complaints. Here is the likely cause and what an engineer actually does about it, so you know what you're paying for.
Usually a loaded filter or a coil furred with dust, pet hair and cooking grease. The fan is working as hard as ever; the air just can't get past the blockage.
On the visitFilters washed or replaced, evaporator coil foam-cleaned, blower wheel checked for build-up, airflow re-measured at the louvres.
Damp sitting on the coil and in the drain tray grows biofilm. It is the most common reason a unit is described as "making the room smell old".
On the visitCoil and tray sanitised, drain line flushed and tested, fan barrel cleaned, and a dry-cycle setting enabled if your unit supports one.
A blocked or badly sloped condensate line backs water up into the tray until it spills over the front edge — often onto plaster or skirting.
On the visitDrain cleared and vacuum-tested, gradient checked along the run, tray reseated, and the surrounding wall inspected for existing damage.
Short-cycling points to refrigerant pressure, a sensor reading badly, or a condenser that cannot shed heat because it is boxed in or clogged.
On the visitPressures and temperature split read, sensors verified, condenser fins cleaned, electricals and contactor checked, findings explained before any repair.
Not sure which one fits? Describe it in your own words on the booking form — "noisy, then nothing" is a perfectly useful description, and it tells us which parts to bring.
Choosing correctly saves a wasted visit. If you're between two, book the service — an engineer can escalate on the spot.
The planned clean and health check that keeps a working unit working, ideally before the first hot week rather than during it.
Something has changed — no cooling, tripping, water, or a noise that wasn't there last month. Diagnosis first, repair once agreed.
An honest survey when a unit is old, undersized or expensive to keep alive — including the case for keeping it another season.
The same six stages run on every maintenance visit. Ask the engineer to talk you through any of them while they work.
| Stage | What happens |
|---|---|
| Stage 01Protect the room | Sheeting under the indoor unit, furniture moved clear, and a quick note of any existing marks on the wall before a panel comes off. |
| Stage 02Read it running | Supply and return temperatures, the split between them, and current draw are recorded while the unit is still in its usual state — the numbers mean nothing after cleaning. |
| Stage 03Strip and clean | Filters washed, evaporator coil treated and rinsed, blower wheel cleared, louvres and casing wiped down, and the drain tray sanitised. |
| Stage 04Drain and seal | Condensate line flushed, flow confirmed at the outlet, gradient checked for sagging, and insulation on the pipework repaired where it has split. |
| Stage 05Outdoor unit | Condenser fins cleaned, fan and mounts checked, debris cleared from the base, electrical connections and contactor inspected for heat marks. |
| Stage 06Re-test and hand over | Readings repeated and compared with stage two, remote and timer functions confirmed, then a walk-through of what we found and what to watch. |
If a stage uncovers something outside a service — a failing fan motor, a refrigerant leak, corroded wiring — we stop, show you, and quote it. You decide whether it happens today.
Half the call-outs we attend could have waited another year. These five habits cost nothing and make the next service shorter.
Tell us the property and roughly when suits. We reply with the windows we can hold and what the visit will cover.
