The right heat pump for the right room.

The heat pump problem

  • Too small for the room and it'll run flat out but never get warm.
  • Too big and it'll cycle on and off, waste power, and wear out early.
  • Right size, wrong spot on the wall, and it's blowing at the couch or straight past the bed.
  • A unit picked to make the sale, not to suit the room.

A heat pump is only as good as the model you pick and where you put it.

That's why we do a free site visit before we quote anything. We look at the room, the layout, the sun exposure and the insulation, then match it to the Mitsubishi model that actually suits your place.

Hundreds of installs across Whanganui. We know which one works where.

Sized at the site visit, not over the phone.

  1. Give us a call

    Tell us the room, the problem, and roughly what you're after. We'll book a look.

  2. Site visit and sizing

    We come out, measure the space, check the insulation and the sun, and work out the real heat load. That's what picks the model, not a guess.

  3. Clear quote, no surprises

    A fixed price with the unit, the install and the certification spelled out. You know the number before we lift a tool.

  4. Installed tidy

    Head mounted level, pipework run clean, outdoor unit sited well, all wired safe. We leave the place how we found it.

  5. Signed off and serviced

    Every install tested, certified, paperwork in your hand. Same crew back for servicing down the track.

Lossnay by Mitsubishi

Fresh air in. No heat lost.

A damp, stuffy house is a cold house. Lossnay fixes it at the source.

Lossnay pulls the stale, damp air out of the house and brings fresh, filtered air in from outside. Not attic air, real outdoor air. On the way through, it uses the heat from the outgoing air to pre-warm the incoming air, so you're not throwing your heating out the window with it.

Less condensation on the windows. Less mould in the corners. A house that feels drier and warmer on the same power.

In summer, it does the opposite. On hot days it bypasses the heat recovery and pulls cooler outdoor air in, cooling the house without opening a window.

What Lossnay solves:

  • Condensation on windows and walls
  • Mould in corners and around window sills
  • Stuffy, stale indoor air
  • Overheating in summer
  • High CO2 and allergen levels

Pairs well with your heat pump. Together they keep the whole house comfortable, not just the room the unit's in.

How Lossnay keeps a house fresh without losing the heat

Installed by us. Serviced by us. Same number in five years.

That's Southcombe.

    “Southcombe Electrical team in Whanganui went above and beyond when installing a heat pump for Mum. Unlike other companies that choose the easiest spot for themselves, Southcombe Electrical carefully assessed the room layout and Mum’s needs to find the most effective location for warmth and comfort. Their thoughtful approach and attention to detail truly stood out. Friendly, professional, and genuinely listened to what we wanted. It’s rare to find a team that values both technical quality and personal care so equally. Wonderful service from start to finish—a great company that’s clearly committed to doing things right. We are so happy with the quality heat pump and nice to be warm :-). Thank you, Holly and the Southcombe Electrical team!”

The questions people ring us with.

How do I know what size heat pump I need?

Depends on the room size, insulation, sun exposure, and how you use the space. That's why the free site visit exists, we measure up properly instead of guessing over the phone.

How long does a heat pump install take?

Most standard back-to-back installs take a day. Bigger jobs or trickier locations (villas, awkward cavities, multiple units) can take longer. We'll tell you exactly at quote time.

Can I add a heat pump to an old switchboard?

Sometimes yes, sometimes no. Old boards can struggle with modern loads like heat pumps. If yours is 25+ years old or has ceramic fuses, we'll check it during the site visit and give you an honest answer.

What's the warranty on the unit and the install?

Mitsubishi units come with 5-10 year manufacturer warranties depending on the series. Our workmanship is backed by our own guarantee, if something we did isn't right, we come back and sort it.
