Heat pump installation in Windsor
Most Windsor homes had a heat pump by 2018, so plenty of them are now eight years old or more. Mahdi and our heat pump installer swap tired units for new ones, and put first heat pumps into the homes still heating another way.

Out: Old heat pumpIn: a heat pump sized to the room
A heat pump’s working life is about 15 years, so a unit put in around 2011 or earlier has had its run.

Mahdi and our heat pump installer do every job together: the unit, the pipe run and the wiring. At the quote visit, Mahdi looks at the room, where the outdoor unit can go and your switchboard’s capacity, then quotes.
About Mahdi and the teamWhat we do in Windsor
For a Windsor home with an older heat pump, the job is a replacement: the old indoor unit off the wall, a new one sized for the room, and the outdoor unit set where it has space to breathe. If the lounge has been opened up to the kitchen since the first unit went in, Mahdi sizes the new one for the bigger room.
We also put in first heat pumps, multi-room systems so the bedrooms are warm too, and fixed heat pumps for Windsor rentals that need heating in the main living room.
On the quote visit Mahdi reads the old unit’s label, looks at the wall it’s on and the space the outdoor unit has, and checks the circuit it runs on. If the old one never warmed the far end of the lounge, he sizes up or moves it; if it did, the new one goes straight back in its place.
Heating a Windsor home
Windsor took to heat pumps early, and fewer homes here lean on a wood burner than across most of the city. That makes it a replacement suburb. A unit that went in before 2018 is at least eight years old now, and one from the early 2010s is close to the 15-year working life of a heat pump.
Windsor sits inside the Invercargill airshed too. Any wood burner put in before September 2005 can’t be used any more, so a house still keeping an old burner as a backup is better off with a second heat pump. Mahdi checks the old unit when he comes to quote and tells you straight whether a service will carry it another winter or it’s time to swap it.
Whichever way it goes, the swap is planned around you: the old unit stays in service until install day, so the house is never left without heat.

Use the form with a photo of the wall and the old unit or heater, or call 0800 164 106.
Mahdi comes out and quotes
He looks at the room, where the outdoor unit can go and your switchboard’s capacity for the new circuit, then quotes the heat pump and the wiring together.
Install day
Mahdi and our heat pump installer take the old unit down if there is one, put the new indoor unit up, set the outdoor unit and run the pipes, and Mahdi wires it in from the switchboard.
Warm and handed over
We run it on heat, set the timer with you and show you the filter: a clean once a month through winter keeps it working well.
A great job well done. Mahdi is professional but friendly, as well as honest and efficient. This is the third time he has done work for us and we will certainly call him again.
Very happy with Mahdi’s work. He was professional, reliable, and easy to communicate with. 5 stars service. Highly recommend.
Great job, well priced and appreciated going the extra mile to complete the job on a saturday as well
Tips for Windsor homes
- Photograph the label on the side of your old indoor unit: it tells Mahdi the model and roughly when it went in.
- If the old outdoor unit sits in a corner or right under a window, ask about moving it while the new one goes in.
- Book the swap in spring or summer, before the frosty months.
- Tell us if a second room needs heat too: two units quoted together share one visit.
Windsor questions
Can the new heat pump go where the old one was?
Where the old unit heated the room well, yes: the new one goes back on the same wall. If it sat in a corner or never kept up, Mahdi suggests a better spot when he comes out to quote.
How old is too old for a heat pump?
A heat pump’s working life is about 15 years. Past that, or with a big part gone, a replacement is the better spend.
Do you replace heat pumps in Windsor rentals?
Yes. A fixed heat pump in the main living room is the heating a rental needs, and we set install days that suit your tenants.
We also put heat pumps in nearby in Rosedale, Gladstone and Richmond. All areas
