Mr Cool Mr Heat has been keeping Melbourne homes comfortable for over a decade. The person who quotes your job works for the same business as the person who installs it — and the same business you ring two summers later.

What we set out to do

Our goal is simple enough to state: every home in Melbourne should have access to dependable, environmentally sound and affordable heating and cooling. Nobody should have to choose between a comfortable house and an energy bill they can live with.

In practice that has meant leaning hard into efficient reverse cycle split systems and cassette air conditioners, supplied and installed by our own team. Melbourne's climate suits heat pumps almost perfectly, and swapping a tired old unit for a modern inverter through our new for old replacement service is one of the biggest levers most households have on running costs. We have helped customers avoid well over ten thousand kilograms of CO₂ through those upgrades.

How we work

  • We size systems on the actual space, not a rule of thumb
  • We quote fixed prices in writing, with the model named
  • We tell you when repairing is smarter than replacing, even though replacing pays us more
  • Every job comes with a compliance certificate
  • We turn up when we said we would, and we clean up before we leave

Credentials

What we are licensed to do

ARC refrigerant licence

Refrigerant handling in Australia requires an Australian Refrigeration Council licence. Venting refrigerant to atmosphere is illegal and environmentally serious — we recover it properly on every removal.

Registered electrical contractor

All electrical work is carried out and certified by a registered electrical contractor, and you receive a Certificate of Electrical Safety on completion.

Fully insured

Public liability insurance on every job, and our own team on site rather than a rotating cast of subcontractors.

Licensed, insured and accountable

Every installation is carried out by licensed tradespeople and certified to Australian standards.

Efficient timely and expert installation of our Mitsubishi split system. So much better for health and pocket than cumbersome gas ducted heating. Thankyou
