After years on the back burner, heat pumps go mainstream with sizzling hot sales

Luise Cox is upgrading her 1960s bungalow in Mississauga, Ont., this week by tearing out and hauling away the old air conditioner and natural gas furnace. Instead, crews are replacing those units with a brand new heat pump (and some extra insulation in the attic, too).
"We needed to upgrade, and environmentally it's better," the 85-year old said. "We're spending a lot on heating and cooling, so hopefully this will help."
Heat pumps, which have been promoted for years, have failed to gain traction with the public. But that's starting to change with rising temperatures, improved technology and government rebates, among the reasons why.
HVAC specialist Peter Messenger says they've gone from 10 per cent of his company's installations to about half almost overnight.
"I'm surprised at how quickly the general public's mindset has changed on heat pumps," said Messenger, owner of A1 Air Conditioning and Heating in Oakville, Ont., west of Toronto. "I always knew it would happen, I just didn't know it would happen this quickly."
He said heat pumps accounted for about 10 per cent of his sales last year but now make up about 50 per cent.
Sales are growing so quickly that Messenger said he wonders whether heat pumps could even wipe out the sales of new air conditioners in homes in a few years and put a significant dent in the number of natural gas furnaces.
A heat pump often looks like an air conditioner and can function the same way. They cool a home by absorbing the heat inside and releasing it outside. But unlike an air conditioner, they can reverse the process in winter — heating a cold house without the need of a burner like a furnace, by transferring heat from where it's not needed to where it is: inside.
"We won't sell air conditioners. Everything will be a heat pump" in a few years, Messenger said. "People may still keep their gas furnaces, but as time goes on, I think we're going to see less and less gas meters on people's homes."
Heat pumps existed for decades, and more than 400,000 were installed in Canada in 2000, but
