Reverse cycle air conditioning

Reverse cycle just means one air conditioner that heats as well as it cools. In summer it pulls heat out of the house; in winter it runs the same cycle backwards and pulls warmth from the outside air in — which is why it's a heat pump, and why it costs about a third of gas ducted to run for the same warmth. One head on the wall does a room, ducted in the roof does the whole home, and it's now the upgrade the VEU rebate is written for.

What you get

What’s in the price.

One machine that both heats and cools — a heat pump on the wall or in the roof. It's the cheapest way to heat a Melbourne home, it's now VEU-rebate eligible, and it comes in three shapes: a split for a room, multi-head for a few, ducted for the whole house.

One machine, both seasons. A reverse-cycle unit runs the refrigeration cycle both ways — cooling the house in February and warming it in July off the same box on the wall. No separate heater, no second system to service, no gas line to run.

How the job runs

What happens on a reverse cycle air conditioning install.

  1. 1

    Room-by-room heat-load calc

    We walk the home, check ceiling height, window aspect and insulation, then compute the actual kW load. Nothing gets guessed, a 5 kW room quote sizes to a 5 kW unit, not a 7.

  2. 2

    Written fixed-price quote in 12 hrs

    Back to you inside 12 business hours with the model number, capacity, line-set length, controller spec, warranty position and total installed price. No 'from $X' bait.

  3. 3

    Order stock, book install day

    Mitsubishi warehouse in Melbourne is same-day on common stock. We confirm your install day the moment the unit lands with us.

  4. 4

    Install day, usually one visit

    Single-split back-to-back is 3-4 hours on site. Multi-head or ducted is a full day. Drop sheets down, dust extraction on the wall cut, conduit colour-matched outside.

  5. 5

    Test, commission, walk-through

    We run it up, check refrigerant pressures, walk you through the remote and MELCloud Wi-Fi setup. You sign the job card when you're satisfied, not before.

  6. 6

    Compliance certificate emailed in 24 hrs

    Electrical and refrigeration compliance docs into your inbox by end of business the next day. Warranty registered with Mitsubishi in your name at the same time.

Common questions

What does “reverse cycle” actually mean?

It's an air conditioner that works both ways. In summer it moves heat out of the house to cool it; in winter it reverses and moves heat from the outside air into the house to warm it. That makes it a heat pump, and it's why one unit covers both jobs instead of a separate heater and cooler.

Is reverse cycle really cheaper than gas heating?

Yes, and by a wide margin on a Melbourne winter. A heat pump delivers roughly three units of heat per unit of electricity, so for the same warmth it costs about a third of what gas ducted does to run. The saving grows every time gas prices rise.

Split or ducted — which do I need?

A split heats and cools the room it's in, so it's the answer for a bedroom, a living room or a granny flat. Ducted puts one system in the roof and vents every room, zoned so you're not paying to condition empty bedrooms. Three or four rooms without going ducted is where a multi-head fits. We size it to your house at the quote.

Does it actually heat in a cold Melbourne winter?

Yes. Modern reverse-cycle systems hold their rated heating output down to around 2 °C and keep working well below that — the Mitsubishi Hyper Heating range in particular is built for it. For the frost pockets up in the hills we spec the cold-climate models rather than a standard unit.

Is reverse cycle eligible for the VEU rebate?

In most cases, yes. Reverse-cycle upgrades are a core Victorian Energy Upgrades activity, especially replacing an old gas or electric heater. Where your property qualifies we handle the paperwork and take the rebate straight off the installed price at the quote.

How much does a reverse-cycle system cost?

A single split starts from around $2,199 installed; a whole-home ducted system is a bigger job. Because the range is so wide we quote it to your house rather than a 'from' number, and the VEU rebate comes off where it applies. The written quote is the number you pay.

Quoted Mon, installed Fri

Took the old gas Rinnai out, dropped in a Reclaim heat pump, sorted the VEU rebate so it came straight off the price. Bloke on the phone is the bloke on the tools, refreshing.

Rebate handled, didn't lift a finger

The VEU paperwork looked scary online. They filled it all in, I signed once at the quote and once on the day. Rebate was already in the price. Painless.

Bedroom Mitsubishi went in before lunch. Neat pipework, brackets straight, temp checked before they left. Would use again for the lounge.

Actually got up in the roof

Had three quotes for a ducted system. These guys were the only ones who actually crawled into the roof. Middle of the pack on price but installed cleaner than the others would have.

Full ducted retrofit over two days. When they left the roof cavity was tidier than they found it and the driveway had been swept. Small thing but it matters.
