frequently asked questions

Everything you need to know about our heating and cooling services, installations, and rebates.

Do you help with government rebates?

Yes. We help customers understand what government rebate options may be available when upgrading to eligible heating, cooling, or hot water systems. We can guide you through the process, explain what may apply, and help you take the next step with a free quote.

Depending on the system you are replacing and the new energy-efficient system being installed, you may be eligible for a rebate of up to $5,000. In many cases, upgrading can also help reduce ongoing energy costs, with average household savings ranging from $120 to $1,100 per year.

Eligibility can depend on your current system, the type of replacement being installed, and current program requirements. In many cases, replacing an older gas heater with an energy-efficient air conditioning system may open up access to larger discounts.

We supply and install split systems, multi-split systems, ducted reverse cycle air conditioning, gas ducted heating, evaporative cooling, add-on cooling systems, and hot water heat pump systems. Rebate opportunities are generally linked to selected energy-efficient upgrades using approved products.
