What moves a quote up: a larger or two-stage/variable-speed furnace, re-routing the venting, a gas line change, a tight mechanical room, or after-hours emergency work. Get at least two written quotes that list the model number, the permit, removal of the old unit and the warranty.
Signs it's time to replace
- The furnace is 15 years or older and needs a major repair.
- Repairs keep coming back in the same winter.
- Heating bills are climbing even though your use hasn't changed.
- Rooms heat unevenly, or the furnace short-cycles or makes new noises.
- A technician finds a cracked heat exchanger. That is a safety issue, not a judgment call.
The rule of thumb many Edmonton contractors use: over 15 years old and the repair costs more than half of a new unit, replace it.
Permits: what a proper install includes
Furnace replacement in Edmonton needs City permits and an inspection. Contractors must be licensed with the City of Edmonton, and the permit application asks for the new furnace's make, model and BTU rating plus venting details. The new equipment has to be sized to the home's heat loss, so a good installer measures rather than just matching the old furnace's size.
Before you sign, ask: who pulls the permit, when is the inspection, and is a heat loss calculation included?
Thinking about a heat pump instead?
If your furnace is near the end of its life, you may be in exactly the situation the new federal heat pump rebate targets. A gas furnace on its own gets no rebate right now; a heat pump, or a heat pump with a furnace as backup, may. Compare the two for Edmonton winters or read the rebate guide.
Questions
Should I repair or replace my furnace?
A common Edmonton rule of thumb: if the furnace is over 15 years old and the repair would cost more than half the price of a new unit, replacement is usually the better buy.
Do I need a permit to replace a furnace in Edmonton?
Yes. Furnace replacement needs City of Edmonton permits and an inspection. Contractors must be licensed with the City and normally apply for the permits themselves. Ask to see the permit number.
How long does a furnace replacement take?
A straightforward swap is usually done in a day. Jobs that need new venting, a gas line change or ductwork can take longer.
Can I get a rebate on a new gas furnace?
Not on its own at the moment. Edmonton's Clean Energy Improvement Program will only finance a high-efficiency gas furnace when it's installed together with a heat pump, and the federal rebate is for heat pumps.
