Everything Kocev Services does
Seven trades, one registered tradesman, Auckland-wide. Heat pumps and the wiring behind them are done by the same person on the same day, which is the whole reason this list is as long as it is.
Three jobs we're set up for
These are the jobs booked in most weeks, each with a page of its own covering what's included, how it is done and how long it takes.
Heat pump supply & installation
- Sized to the room, not guessed
- Single room and multi-room systems
- Installed, tested and warranty registered
- Usually a single day on site
Switchboard upgrades & replacements
- Ceramic fuses and old boards replaced
- RCD protection on every circuit
- Circuits labelled, board photographed
- Certificate of Compliance supplied
Cabin & minor dwelling fitouts
- Sub-main run from the house board
- Sub-board, points, lighting, smoke alarms
- Heat pump wired in at the same time
- Certified and ready for sign-off
Everything else we're licensed and equipped for
Heat pump work and electrical work usually turn up on the same house. Having both under one contractor is what saves you the second booking, the second callout fee and the argument about whose job the wiring was.
Air conditioning & heat pumps
Supply, install, service and repair, any brand, whether we put it in or not.
- Heat pump supply and installation
- Split system installations
- Multi-room heat pump systems
- Heat pump servicing and repairs
- Preventive maintenance
- Fault finding and diagnostics
Ducted air conditioning
Whole-home systems, hidden in the roof space, zoned so you only heat the rooms you're using.
- New ducted system installations
- Replacement of existing systems
- Zoning systems
- System upgrades
- Repairs and servicing
Home ventilation & heat recovery
Condensation on the windows, mould in the corners, a musty smell in the wardrobes: that is the air not moving, not the house being old. Set up properly, a ventilation or heat recovery system fixes it quietly, in the background, for a few cents a day.
- New system supply and installation
- Positive-pressure and balanced-pressure heat recovery
- Filter replacement, G3, G4, F7 and allergy grades
- Wall controller resets and reprogramming
- Full system checks and airflow testing
- Motor, ducting and roof intake repairs
- Servicing and maintenance, any brand
- Replacement once a repair is no longer worth it
We work on HRV, DVS and SmartVent (Simx) systems whoever installed them. Once yours is out of warranty you are free to have it serviced by any qualified technician, which usually means the same job sooner and for less. Filters want replacing about every 12 months, sooner if you are near a main road, on gravel, or someone in the house has asthma or hay fever.

- Alarm system installation

- Remote viewing setup

Appliance installation & repairs
The hard-wired appliances that need a registered electrician, not a delivery driver.
- Whiteware appliance installation
- Oven installation
- Cooktop installation
- Rangehood installation
- Dishwasher installation
- Washing machine installation
- Dryer installation
- Fault diagnosis and repairs, where applicable
TV & home entertainment
Mounted level, cables out of sight, everything working before we leave.
- TV wall mounting
- TV installation and setup
- Cable concealment
- Soundbar installation
- Home entertainment system setup
Two things we don't do, so you're not left guessing: large commercial fitouts, and anything needing more than one person on site. Kocev Services is one registered tradesman, and the work is quoted on that basis.
