Aircon Servicing & Repair in Manukau City

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.

If you run multiple units daily, yes — contracts usually price each visit 15-30% below one-off rates, include priority booking during heatwaves, and some include minor parts. For a single, lightly used unit, paying per visit is usually cheaper.

Check the simple things first: thermostat mode and setpoint, dirty filters, and blocked outdoor unit airflow. If those are fine, the usual culprits are low refrigerant from a leak, a failed capacitor or fan motor, or a dirty coil. Low refrigerant always means a leak — a technician should find and fix the leak, not just top up the gas.

Inverter units vary compressor speed instead of switching on and off, so they hold temperature more steadily and cost 20-40% less to run for long daily use. Non-inverter units are cheaper upfront and fine for rooms cooled a few hours a day. For daily whole-day use, the inverter premium usually pays back in 2-3 years.

Dirty coils and filters make the compressor work harder for the same cooling — energy use can rise 15-30% before you notice weaker airflow. A failing capacitor or low refrigerant has the same effect. A service that restores the unit to spec usually pays for itself in a hot season.

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.

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.
