A heat pump loses its edge quietly. Dust and mould build up on the filters, coil and fan barrel where you can’t see them, and the unit slowly works harder to deliver the same warmth – the power bill creeps up, the airflow weakens, and that musty smell appears when it starts. Left long enough, an unserviced unit fails early, and manufacturers can decline warranty claims on units with no maintenance record. An annual service reverses all of it.
We service and repair every make and model of heat pumps in the Manawatū – Daikin, Carrier, Mitsubishi Electric, Panasonic, Fujitsu and the brands we don’t even sell – including units installed by companies that no longer exist. The same qualified AC technicians and registered electricians who install our new systems do the servicing, as the dedicated heat pump arm of trusted electrician team Budget Electrical.
Heat pump servicing · Palmerston NorthA real service is more than a filter rinse. It reaches the parts you can’t see – the indoor coil, the fan barrel, the condensate drain – then checks the refrigerant pressures, tests the electrical connections, and measures actual heating and cooling output before we call it done.
No musty smell. No mystery rattle. No power-bill creep.
Here’s what a full service actually involves: we strip and wash the filters, deep-clean the indoor coil and fan barrel where the dust and mould really live, clear the condensate drain, wash down the outdoor unit’s coil, check the refrigerant pressures for leaks, and tighten and test the electrical connections. Then we run the unit in both heating and cooling and measure the air temperatures coming off it – the same commissioning test we give a brand-new install.
Once a year is the rhythm. Clean the filters yourself every couple of months (five-minute job – see the FAQ below), and book the professional service annually – ideally in late summer or autumn, before the first Manawatū frost finds out whether your unit is ready and before the winter rush books out the calendar. Homes with pets, dusty sections or all-day running benefit from a six-monthly clean.
We service all makes and models – including units other companies installed and brands we don’t sell. That matters for your warranty: most manufacturers require regular maintenance to keep cover valid, and a claim on a neglected unit can be declined. Every service ends with a written record of what was cleaned, checked and measured, which is the cheapest warranty insurance you can buy.
A standard high wall service takes about an hour and costs $249 including GST; ducted and multi-split systems take longer and we’ll confirm the price when you book. If the technician finds a genuine fault, you get a plain-English explanation and a price before any repair work starts – and if a unit is truly at the end of its life, we’ll tell you straight and show you the replacement options rather than charge you to keep a dying unit alive.
Annual service · All makes & modelsThe classic symptoms: it doesn’t heat like it used to, ice on the outdoor unit that never clears, water dripping from the indoor unit, error lights flashing, a rattle that wasn’t there last winter, or a unit that starts and stops in short bursts. A surprising number of “faults” are really just blocked filters and a dirty coil suffocating the airflow – those we fix on the spot with a deep clean. The genuine faults get diagnosed properly, not guessed at.
Because our technicians are qualified in air conditioning and our electricians are registered, we can chase a fault from the refrigerant circuit to the circuit board in a single visit – no second contractor, no “that’s the sparkie’s problem.” Repairs use genuine parts, and if your unit is still under manufacturer warranty, we’ll tell you before you spend a dollar.
We’ll also be honest about the maths. If an old unit needs a major part, a repair often doesn’t stack up against a new heat pump installed from $1,750 with a fresh 5-10 year warranty. You get both numbers and you make the call. The full detail lives on our heat pump repairs page.
Repairs · Diagnosed & fixedA pool heat pump works longer hours than anything else on your property, and it does it outdoors – leaves, grass clippings and airborne dust slowly choke the evaporator fins until the unit runs flat-out for less heat. An annual pre-season service means the pool is warm when the first hot weekend arrives, not three weeks and one repair bill later.
Ventilation systems only work while their filters are clean. If your home has an HRV, DVS or SmartVent system, a clogged filter means it’s pushing less air – and dirtier air – into the house every day. We replace ventilation filters and service the fans, sensors and controls on all the main systems, and if you’re weighing up a new system entirely, our home ventilation page covers the SmartVent range we install.
The practical move: book the heat pump and the ventilation filters as one visit. One team, one invoice, everything done on the same morning – and landlords get dated service records for the Healthy Homes file without chasing three different contractors for paperwork.
Pre-season heat pump servicing in Palmerston NorthAnyone with a hose can rinse a filter. A real service reaches the coil, the fan barrel, the drain, the gas pressures and the electrics – miss those and you’ve paid for a clean that changed nothing. Here’s what we commit to on every visit.
A heat pump is a refrigerant machine wired into your switchboard, and most faults could live on either side of that line. Our technicians hold air conditioning qualifications and our electricians are registered, so both halves get checked properly – in one visit, by one team.
Daikin to Fujitsu, three years old or fifteen, installed by us or by a company that vanished a decade ago – we’ll service it, repair it, and tell you honestly where it sits in its lifespan. No “we didn’t install it” runaround.
Every service ends with a written record of what was cleaned, checked and measured. That paper trail is what keeps manufacturer warranty claims alive if anything ever fails – and it slots straight into a landlord’s Healthy Homes file.
A standard high wall heat pump service is $249 including GST and takes about an hour. Ducted and multi-split systems take longer, so we confirm those prices when you book. If the technician finds anything beyond the service itself, you’ll get a clear price before any repair work starts – no surprises on the invoice.
Clean the filters yourself every two to three months, and book a professional service once a year – ideally in late summer or autumn, so the unit goes into winter clean, gas-checked and ready for the frosts. Homes with pets, dusty rural sections, or a unit that runs all day (or all night in summer) benefit from a six-monthly professional clean.
Yes, and you should – it’s a five-minute job. Turn the unit off, lift the front panel, slide the filters out, vacuum them (or rinse in cold water and let them dry fully), then clip them back in. That keeps the airflow strong between services. What it doesn’t reach is the coil, fan barrel, drain, refrigerant and electrics behind the filters – that’s the once-a-year professional part.
Filters stripped and washed, the indoor coil and fan barrel deep-cleaned, the condensate drain cleared, the outdoor coil washed down, refrigerant pressures checked for leaks, electrical connections tested and tightened, and the unit run in both heating and cooling with its output temperatures measured. You get a written record of what was done and how the unit performed.
It can. Most manufacturers require regular maintenance as a condition of their warranty, and a claim on a unit with no service history can be declined – an expensive way to save a service fee. Every service we do ends with a dated written record, so if you ever need to claim, the paper trail is already in your favour.
That smell is mould and bacteria on the indoor coil and fan barrel – the unit is warm and damp inside after every heating cycle, and airborne dust gives mould something to grow on. A filter rinse won’t fix it because the growth is behind the filters; a professional deep clean removes it at the source. If the whole house smells damp, that’s a different problem – see our home ventilation systems.
All the time – it’s most of our servicing work. We service and repair every make and model: Mitsubishi Electric, Daikin, Carrier, Panasonic, Fujitsu and older or discontinued brands too. If a unit is on its last legs we’ll say so honestly and show you the replacement options with real installed prices, so you can decide with both numbers in front of you.
