At Duncan’s Plumbing Heating and Air Conditioning, we provide comprehensive heating and cooling solutions, specialising in reverse cycle air conditioning. Our services include supplying and installing correctly sized units, providing precast bases and supports, and managing all necessary drainage and electrical connections. We also offer expert installation of gas ducted heating—whether in-ceiling or underfloor—and reliable servicing and installation of evaporative cooling systems.
Gas Ducted Heaters
Designed to efficiently heat your entire home, gas ducted heating systems can be installed under the subfloor, in the roof space, or externally. These units are compatible with both natural gas and LPG. The system works by drawing air through a return air grille into the heating unit, where it is warmed and then circulated throughout the home via a network of ducts and outlets, available in UPVC or metal. Once the desired temperature is reached, the programmable wall-mounted thermostat signals the unit to switch off, ensuring consistent comfort and energy efficiency.
Pros

- Ability to heat the entire house
- Instant warmth

Wall Hung Split System
Designed to heat a single room or open area, these units can provide the best of both worlds as they can heat and cool your home. These units are comprised of an indoor unit (also known as a head), this is located on the wall, and an outdoor unit (compressor and condenser) this is located externally in a convenient spot either on a concrete support or metal support brackets. Some Split systems can be made into a multi-system where several indoor units are serviced by one outdoor unit; this then gives the homeowner the ability to heat multiple rooms at the same time.

- Can effectively cool and heat the desired area (room)
- Easy and fast installation process

Evaporative Cooling
This is designed to cool the entire home using the warm air surrounding the house.
This unit sits externally on top of the roof surface with consideration of the position. An evaporative cooler draws in the warm air over moistened pads to cool the air down with a wet-bulb maximum temperature difference of 10°C. The cooled fresh air is then filtered throughout a series of ducts within the roof space and is distributed to the outlets (where located) into the house.
We recommend this cooling for those families who like to leave the doors and windows open during the summer months. The cold air is fresh and very different from a reverse cycle air conditioner system. The running costs are a lot cheaper than other forms of cooling and could be considered when thinking of family builds in Canberra.
Pros
- Slightly cheaper set up costs and significantly cheaper running costs
- The air inside your home is not re-circulated
- A natural process of air cooled by water means it won’t dry out the air, or irritate your skin, throat or eyes.
- As hot air is pushed out of the home, doors can be left open
- Works very well in dry climates
