What usually goes wrong

Not cooling or heating. Dirty filters, a blocked outdoor coil, the wrong mode, or low refrigerant from a leak.
Water dripping from the indoor unit. A blocked condensate drain or a cracked tray.
A smell. Mould in the filters or the drain tray. Cleaning fixes it.
Noise. A loose panel, a worn fan, or the outdoor unit's mounting.
Flashing lights or a code. The unit's own fault code. Note it for the engineer.

Rinse the indoor filters every three months yourself. Anything to do with the refrigerant needs an F-gas certified engineer: see F-gas.

Questions we get asked

How much is an air con service in Ireland?

€80 to €210 a unit. Each extra indoor unit adds to it.

Why is my air con leaking water?

Usually a blocked condensate drain. It's a quick fix at a service.

Does air con need regassing every year?

No. A sealed system shouldn't lose gas. If it needs regassing, there's a leak to find and fix first.

Who can regas an air conditioner?

Only an engineer with an F-gas certificate, working for an F-gas certified company.
