One level, a walk-in roof space and a gas heater that has been up there since the house was built. Carrum Downs homes suit ducted reverse cycle on new R1.5 insulated ducts better than almost anywhere we work.
Almost every house in Carrum Downs was built with ducted gas. The suburb grew between the 1980s and the 2000s, when a gas heater in the roof and a row of ceiling vents down the hallway was simply what a new family home came with. Some of those heaters have been replaced once. Many are original, which makes them twenty to forty years old, and the flexible ducts attached to them are the same age.
The good news is the shape of the house. With a single storey and a tiled hip roof there is room to stand in the roof space and reach every duct run. That lets us do the swap the way it should be done: gas heater out, old ducts out, ducted reverse cycle unit in, new R1.5 insulated ducts sized to that unit run to every room. Nothing has to be left behind because it cannot be reached.
It also brings cooling to every room, not only the lounge, and heats for around a third of the running cost of gas heating. A family home with the kids' bedrooms shut all day gets the most from zoning, so we plan the zones with you before quoting. Read about the rest of our Carrum Downs work.
Braemar, Mitsubishi Electric and Hisense ducted units, AirTouch 5 control, and our own crew on the refrigeration, ducts and wiring.
We work out the heating and cooling load from the floor area, ceiling height, glazing and insulation. The old gas heater's rating is not a guide, because cooling a west-facing living room asks for something quite different.
Gas-era ducts were sized for hot air only and have usually gone brittle or been flattened by decades of people crawling over them. We remove them and run new R1.5 insulated ducts with the diameters the new unit needs, plus a properly sized return air.
AirTouch 5 with a sensor in each zone. A common layout is living and kitchen together, the main bedroom on its own and the other bedrooms as a third zone, so nobody pays to heat empty rooms during school hours.
A converted garage, a rumpus room added out the back or a home office in the shed sits outside the ducted layout. A Mitsubishi Electric or Hisense split handles it and is fitted in a few hours.
The full range is on our products page.
Ducted reverse cycle, including the Dominator for homes where the existing ducts have to stay.
Ducted units for tight roof spaces, plus split and multi-head systems.
Ducted and split systems, with anti-corrosive Golden Fin coils on the ducted range.
Zoning control for ducted systems, with a sensor in each zone and control from your phone.
There is no Carrum Downs case study yet. These are from Narre Warren South, Doreen and Cairnlea, all gas ducted family homes.
A 23.5kW ducted reverse cycle system through a whole family home in Narre Warren South, on R1.5 insulated ductwork with 16 round outlets and six AirTouch 5 zones. The owner said solar and a battery would be next.
In Doreen, gas ducted heating made way for a 23.5kW ducted reverse cycle system with 12 vents and seven AirTouch 5 zones. A Reclaim heat pump and an induction cooktop went in during the same job.
The gas ducted system in this Cairnlea home was decommissioned to qualify for the rebate and replaced with an 18kW Mitsubishi Electric ducted unit serving ten vents. The rebate on that job was $6,300.
Ducted reverse cycle on new R1.5 ducts is typically one to two days on site.
We measure the house, count the outlets, look at the insulation and check where the return air and the outdoor unit can go.
Unit capacity comes from the numbers. Zones come from asking who is home and when.
Unit, ducts, outlets, zoning, electrical work and the after-discount price on one page.
Heater and ducts come out through the manhole. The new unit, ducts, dampers and a dedicated circuit go in.
We set the airflow to each room, run heating and cooling, and put the controller app on your phone.
A discount up front, a cheaper winter, and a summer the house can finally handle.
A ducted system is the biggest electrical load most homes will ever have, and Carrum Downs roofs are well suited to covering it. We size both together: see solar and battery in Carrum Downs.
Carrum Downs is in the VEU area. The discount on efficient reverse cycle is at its largest when a gas ducted heater is decommissioned and replaced, which describes nearly every job we quote here. It comes off the quote.
Once the heater is electric, hot water and the cooktop are usually all that keep the gas account open. Replace those and the daily supply charge ends as well.
A single-storey home gives no excuse for leaving thirty-year-old ducts in the roof.
Our default on a Carrum Downs house is full duct replacement. A Braemar Dominator on existing ducts is kept for homes where ducts cannot be replaced, usually two storeys.

Because in a single-storey home there is no reason to. Old gas ducts are sized for heating only, lose more through thin insulation and are often split. New R1.5 ducts sized to the unit are what make the cooling work in February.
It depends on floor area, ceiling height, windows and insulation, so we calculate it for your house. Guessing from the size of the old gas heater leads to a unit that is wrong for cooling.
If it is twenty years old or more, yes. You pick the timing, the VEU discount applies when gas heating is replaced, and you are not left choosing in a hurry in the middle of winter when it fails.
Sometimes. Outlets placed for a gas heater do not always suit cooling, and extensions added since the house was built may have none. We mark any changes on the plan before you agree to the quote.
Three or four suits most three and four bedroom homes here: living areas, main bedroom and the other bedrooms, with a study or rumpus as a fourth if you have one.
Ducted reverse cycle with new R1.5 ducts is typically one to two days from the old heater coming out to the new system running.
We measure the house and the roof space, plan the zones with you and send a written after-VEU price. No obligation.
