Aircon Servicing & Repair in Rolleston

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 chemical wash uses a cleaning solution to strip dirt and mould from the evaporator coil, blower wheel, and drain pan without dismantling the whole unit. Book one when a normal service no longer fixes weak airflow, bad smells, or water leaking from the indoor unit — typically every 12-18 months for heavily used units.

Most charge a call-out or diagnostic fee that covers travel and the first inspection; many waive or credit it against the repair if you go ahead. Confirm the fee, whether it is credited, and any surcharge for evenings, weekends, or urgent same-day visits before the technician is dispatched.

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.
