Working in this area

Humidity and basement moisture

The most humid climate in the province. Basement waterproofing, drainage and dehumidification deserve more attention here than elsewhere in Ontario.

Aluminum branch wiring

Present in some homes built in the late 1960s and early 1970s. It is an insurance issue and requires specific remediation by a licensed electrical contractor, not simple replacement of devices.

What heating and cooling work costs in Ontario

Ontario and federal rebate programs for heat pumps change frequently and can move the effective cost by thousands. Ask the contractor which programs they are currently registered to submit for - registration matters, because some rebates require the installer to be enrolled.

Questions to ask before you hire

Will you perform a heat loss and heat gain calculation, and can I see it?

Who on the crew holds the TSSA gas certificate, and at what level?

Is the equipment warranty conditional on registration or on installer certification?

What exactly is covered by your labour warranty, and for how long?

Does this quote include removal and disposal of the old equipment?

Which rebate programs are you registered to submit for, and do you handle the paperwork?

Warning signs

A replacement quote produced without anyone measuring anything or looking at your ductwork.

Sizing justified purely by matching the old unit.

Unsolicited door-to-door or phone offers for furnace or duct inspections. Ontario has a long history of aggressive HVAC door-to-door sales, and rules restricting it exist for good reason.
