Aircon Servicing & Repair in Gisborne

The most common cause is a clogged condensate drain line — dirt and algae block the pipe and water backs up into the room. Other causes are a dirty evaporator coil that ices over and then melts, a cracked drain pan, or an incorrectly sloped drain pipe. A drain flush during a standard service usually fixes it.

A chemical wash cleans the coil, blower, and drain pan in place. A chemical overhaul dismantles the indoor unit completely, soaks the parts, checks bearings and seals, and reassembles it. Choose an overhaul when a wash has not fixed persistent leaks, noise, or weak cooling, or for units neglected for years.

A common rule: if the repair costs more than half the price of a new unit, or the system is over 10-12 years old and needs a compressor or coil replacement, replace it. Newer inverter units are typically 30-50% more efficient, so heavy users recoup part of the cost through lower bills.

Once a year is the minimum for a system used seasonally; every 3-4 months if you run it daily in a hot climate. Regular servicing keeps coils and filters clean, which protects the compressor — the most expensive part to replace — and keeps energy use down.

A standard single-unit service is typically $120-$250, with multi-unit discounts. Deep hygiene cleans of mouldy indoor units run $200-$350. Winter is peak season in NZ since heat pumps are primarily used for heating — book a service in autumn.

Under the Healthy Homes Standards, rentals must have fixed heating capable of heating the main living room, which is often a heat pump — and the landlord is responsible for keeping it in working order. Tenants should clean filters and report faults in writing.
