Sizing before selling
A replacement furnace should be sized to the house as it is today, after any new windows, insulation or additions, not copied from the old unit's label. The sizing guide explains how that calculation works.
Work is performed by TSSA-certified gas technicians. For air conditioners and heat pumps, work is performed by 313A refrigeration and air conditioning mechanics.

My Hamilton house has small ducts. Can I still get air conditioning?
Usually. Central air needs more airflow than many older duct systems were built to carry, which leads to loud vents and upstairs rooms that never cool. A ductless system avoids that by putting indoor heads in the rooms that need them, connected to an outdoor unit by a small line set. A ductless heat pump can also share the heating with your furnace. See air conditioning installation and heat pumps.
Is there a tax credit or government rebate for a new furnace?
Programs come and go, and the rules change often. Federal and provincial support has tended to favour heat pumps and higher-efficiency equipment over a straight furnace swap. Some programs require an energy assessment before the work starts, so the order you do things in matters. We check which programs are open at the time we quote, so you know before you commit. Keep your invoices and equipment model numbers, since applications usually ask for them. Our guide on rebates and tax credits explains what to check.
Can I get a rebate for an air conditioner in Ontario?
A standard central air conditioner rarely qualifies for a rebate on its own. Heat pumps often do, because they cool in summer and also heat in the shoulder seasons. A cold-climate heat pump paired with your existing gas furnace is a common way to replace an ageing air conditioner and become eligible for whatever program is running. We look up the current programs when we prepare a quote. Read about hybrid set-ups on our heat pumps page.
