One system for every season

Reverse cycle air conditioning gives you heating and cooling from the same system, making it a practical choice for year-round comfort. Trimech can help you choose a system suited to your home, whether you need a split system for selected spaces or ducted air conditioning for broader coverage.

How one system changes with the seasons

A reverse cycle air conditioner uses the same system for heating and cooling, adjusting its operation based on the mode you select.

Cooling system

Cooling when the heat sets in

In cooling mode, the system removes heat from the indoor air and releases it outside, helping lower the temperature inside your home.
Heat pump

Reversing the cycle for warmth

When you switch to heating mode, the process reverses. The system draws available heat from the outside air and transfers it indoors to warm your home.
Seasons

Comfort from the same system

Because heating and cooling are handled by one unit, you can adjust your indoor temperature as the seasons change without switching between separate systems.

What does reverse cycle cost?

Reverse cycle air conditioning costs depend on the system type, capacity, brand and installation requirements. These general ranges can help you budget before requesting a tailored quote.

Split system pricing

A reverse cycle split system may cost around $1,500–$4,500+ supplied and installed, depending on the unit size and installation complexity. Smaller bedroom systems are generally on the lower end, while larger units for living areas cost more.

  • Around $1,500–$2,500 for smaller reverse cycle split systems.
  • Around $2,500–$3,500 for mid-sized reverse cycle systems.
  • Around $3,000–$4,400 for larger-capacity split systems.
  • Extra electrical work or difficult access can increase installation costs.

Ducted reverse cycle costs

Ducted reverse cycle air conditioning generally costs more because it conditions multiple rooms through one central system. A typical installation may range from $8,000 to $15,000+, depending on home size, zoning, system capacity, and installation requirements.

  • Around $8,000–$10,000 for smaller ducted reverse cycle systems.
  • Around $10,000–$15,000 for medium-sized whole-home installations.
  • Around $13,000–$18,000+ for larger or more complex systems.
  • Zoning, extra outlets and electrical upgrades can increase the final cost.

Frequently asked questions

Choosing a reverse cycle system can raise questions about heating, cooling, efficiency and system types. Here are some common questions homeowners want answered before getting started.

Is reverse cycle air conditioning good for heating?

Yes. Reverse cycle air conditioners are designed to both heat and cool, allowing the same system to provide warmth in winter and cooling in summer.
