Warm in winter, cool in summer.
Mitsubishi, Daikin, the lot. Sized right for your space, installed and serviced properly by a local crew who'll still pick up the phone later.
Cold house, big power bill, no idea which one to buy.
Every brand says theirs is the best. The box at the hardware store looks the same as the one the installer quotes double for. And the wrong size unit will either never warm the room or burn power trying. You don't want a sales pitch. You want someone who'll look at your actual house and tell you straight what it needs. That's the job.
Sized right, installed properly, serviced later.

Six Mitsubishi models, one that's right for your room.
No prices on the wall and no upsell. The site visit picks the model, not the brochure.
High Wall
The one most people picture on the wall. Quiet, efficient, does the everyday job well.
Good for: lounges, bedrooms, the main living space.
GS Series
The honest workhorse. Solid heating and cooling without paying for extras you won't use.
Good for: bedrooms, sleep-outs, keeping the budget tidy.
AP Series
The step up. Better efficiency, quieter running, smart control from your phone.
Good for: living areas you run a lot, colder rooms, lower power bills.
EF Designer
Flat-faced, clean lines, made to look good on the wall instead of shouting for attention.
Good for: renovations and new builds where the room's had thought put into it.
LN Black Diamond
The premium designer unit. Black or silver finish, the quietest in the range, a statement piece that also happens to heat the room.
Good for: architectural homes, feature walls, anyone who wants it to disappear or stand out.
Floor Console
Sits low on the wall like a radiator. Great where you can't mount up high, and it throws heat at floor level where you actually feel it.
Good for: villas, rooms with limited wall space, warming a cold floor.
Fresh air in. No heat lost.
A damp, stuffy house is a cold house, and Lossnay fixes it.
Lossnay pulls the stale, damp air out of the house and brings fresh air in, without 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. It pairs with your heat pump so the whole place is comfortable, not just the room the unit's in.
Only the gear we'd put in our own homes
We fit the brands worth fitting, with the manufacturer warranty (usually 5 to 10 years depending on the model) on top of our own workmanship guarantee.

Tell us the room, the problem, and roughly what you're after. We'll book a look.
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.
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.
Installed tidy
Head mounted level, pipework run clean, outdoor unit sited well, all wired safe. We leave the place how we found it.
Tested, certified, serviced later
Fully tested and signed off with the paperwork in your hand. Give us a ring down the track for a clean or a service and we'll sort it.
Heat pump questions, answered straight.
What size heat pump do I need?
Depends on the room, the insulation, the sun and how you live in it. That's exactly what we work out at the site visit, so you get the right size instead of a unit that's too small to keep up or too big and wasting power. We'll tell you straight.
Which brand is best?
The one that suits your room and your budget. We fit Mitsubishi, Daikin and a few others, and we'll be honest about where the extra money is worth it and where it isn't. No pushing you to the dearest unit on the wall.
Can you service the heat pump I already have?
Yes, any brand. A unit full of dust works harder, costs more to run and dies early. We clean, service and re-gas existing heat pumps and let you know if yours is worth keeping or near the end.
How long does an install take?
Most straightforward high wall installs are done in a day. We'll tell you at the quote exactly what your job involves so there are no surprises on the day.
