What we check on a Toshiba service or repair
When we open up a Toshiba unit, we follow a specific checklist. It’s the same process whether it’s a routine service or a fault-finding call.
- Fault codes and controller history: We pull the diagnostic history to see if the unit has been cutting out or defrosting incorrectly.
- Refrigerant pressure: We test the pressure to catch slow leaks before they damage the compressor.
- Coil and filter deep-clean: Toshiba units are prone to airflow restriction if the coil behind the filters gets clogged with dust and pollen.
- Electrical draw and connections: We check the power draw to ensure the unit isn’t working harder than it should.
- Outdoor unit condition: We check the siting, clearance, and drainage. If a Toshiba outdoor unit is boxed in or sitting on the ground, it will struggle to defrost on a frosty Christchurch morning.
How Toshiba units handle Christchurch conditions
Christchurch weather puts heat pumps through two extremes: the dry, dusty nor’west winds and the hard, clear frosts.
- The nor’west dust: The nor’west wind brings fine dust that clogs indoor filters and outdoor coils quickly. If you live on the western side of the city, your Toshiba will need its filters cleaned more often than the manual suggests, or the unit will lose efficiency and start to smell.
- Frost and defrost cycles: Toshiba outdoor units have a defrost cycle to melt ice off the coil. But if the unit is installed in a frost pocket (like the Selwyn plains) or a damp, shaded corner, the defrost cycle runs constantly, which eats into your heating efficiency. We check the outdoor siting during every service to make sure it can drain and defrost properly.

Sizing a Toshiba for your home
We see a lot of undersized units in older Christchurch villas and bungalows. Single glazing and minimal insulation mean the heat pump has to work much harder. Conversely, a Toshiba unit that is perfect for a draughty 1920s house will be massively oversized for a new, airtight townhouse in Halswell. We size the Toshiba from your rooms, insulation, and glazing, not just the floor plan. Sometimes that means a smaller unit than you expected.
Toshiba models we service in Christchurch
We work on the full range of Toshiba residential and light commercial units sold in New Zealand, including:
- High-wall units: The standard single-room installs (e.g., Toshiba Seiya, Alpine).
- Floor consoles: For rooms where high-wall mounting isn’t an option.
- Ducted systems: Whole-home or multi-room setups where the unit is hidden in the ceiling.
- Multi-split systems: One outdoor unit running several indoor units.
Do you install Toshiba heat pumps?
Yes. We fit Toshiba alongside Mitsubishi Electric, Daikin and Fujitsu. If you are building or renovating, we size the Toshiba unit from your house before recommending a model. We will tell you if a smaller unit will do the job. We also check the outdoor unit placement against the Christchurch District Plan noise limits, especially in denser suburbs like Riccarton or Addington.
Toshiba vs. the other brands we service
Toshiba units are generally excellent value and have strong heating outputs. If you are comparing Toshiba to Mitsubishi Electric or Daikin, we can talk you through the differences in noise levels, warranties, and controller features so you can choose what suits your home. Our best heat pump brands guide explains this in more detail.
What areas do you cover?
We service and repair Toshiba heat pumps in every Christchurch suburb, plus Lyttelton and the Selwyn towns of Rolleston, Lincoln, Prebbleton and Tai Tapu.
Toshiba heat pump service questions
My Toshiba heat pump is showing an error code. Can you fix it?
Yes. We carry diagnostic tools for Toshiba units and can pull the fault codes on-site. We will tell you if it's a simple fix or if it's worth replacing the unit.
How often should a Toshiba heat pump be serviced?
Once a year. Before winter is best. If you live in a dusty area or use the unit heavily, we recommend a coil clean every 12 months.
Do you supply Toshiba parts?
We source genuine Toshiba parts for repairs when needed.
Will a Toshiba heat pump work in a frosty Christchurch winter?
Yes, but the outdoor unit needs to be placed correctly so it can drain and defrost. We check this on every install and service.
