Heat pump installation in Rosedale
Rosedale and Hargest, home to James Hargest College’s two campuses, took to heat pumps early, and most homes here are owner-occupied. That makes it replacement country: Mahdi and our heat pump installer swap worn units for new ones sized for the room as it’s used today.

Out: Old heat pumpIn: a heat pump sized to the room

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 Rosedale
A replacement here is often more than like for like. If the old unit ran flat out every winter, or the living area has opened up since it went in, Mahdi sizes the new one bigger, or adds a unit for the bedrooms.
Where a unit still has years in it, a service before winter keeps it heating well, and Mahdi tells you straight which way he’d go.
A Rosedale swap starts with the old unit’s label and a look at how it has been used: a lounge-only unit asked to heat the whole house runs flat out every winter. Mahdi sizes the replacement for the job it really does, and adds a second unit where the house needs one.
Rosedale’s early heat pumps
Rosedale and Hargest had heat pumps in more homes by 2018 than almost anywhere else in Invercargill. That’s a lot of units now eight years old or more, and the first ones are close to the 15-year working life of a heat pump.
The area is inside the Invercargill airshed. Non-compliant burners from 2005 to 2010 must stop by 1 January 2030, though a burner on the national authorised list isn’t caught. Either way, a heat pump is the simpler heat to live with.
Early heat pumps are due all over Rosedale. Book the swap in the warmer months and the new unit is in and run up well before the frosts.

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.
Power Surge Ltd has done an excellent job at our house. They went above and beyond to deliver the work on time and the quality is very high. Not only was he work well done, the communication and response time was great. Would definitely recommend 😃
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.
Tips for Rosedale homes
- Note what the old heat pump does on a frosty morning: it tells Mahdi whether to size up.
- Photograph the old outdoor unit and where the pipes run: the route may suit the new one.
- Ask for the replacement and a service quoted side by side if the unit is borderline.
- Ask about a multi-room system if the old setup was a lounge unit and plug-in heaters in the bedrooms.
Rosedale questions
Will the new unit be bigger than the old one?
If the old one ran flat out every winter or the room has changed, yes. Mahdi measures the room as it is now.
Can the new unit use the old pipe route?
Where the route suits, the new pair goes back the same way. Mahdi checks it on the quote visit.
Do you add heat pumps for bedrooms?
Yes: a second unit, or a multi-room system off one outdoor unit.
We also put heat pumps in nearby in Windsor, Glengarry and Waikiwi. All areas
