Buyer guide

Hiring a HVAC company in Ottawa

What separates a great HVAC company from a cheap quote, and the questions worth asking before you sign.

  • Size the equipment, do not just swap it

    A furnace or heat pump that is oversized short-cycles and wears out early. A good Ottawa installer does a heat-loss calculation for your home rather than matching the old unit's number.

  • Ask about heat pumps and rebates

    Cold-climate heat pumps now work through Ottawa winters and can cut energy costs. Rebate programs change year to year; ask which current federal or provincial rebates your project qualifies for.

  • Confirm the licence and the permit

    Gas and HVAC work is licensed in Ontario. Confirm the company is licensed and pulls the required permit, and get the model numbers and warranty in writing.

  • Get a maintenance plan

    An annual tune-up before winter catches worn parts before they fail on the coldest night. Ask what a maintenance plan covers and whether it includes priority emergency service.

Common questions

HVAC in Ottawa, answered

How much does a new furnace cost in Ottawa?
A high-efficiency furnace installed in Ottawa typically runs 4,000 to 7,000 dollars depending on size and model. Cold-climate heat pumps cost more but may qualify for rebates; get a written, sized quote.
Do HVAC companies in Ottawa offer emergency service?
Many offer 24/7 emergency service through the winter, which matters when a furnace fails in a cold snap. Confirm after-hours availability and rates before you sign a service agreement.
How often should I service my furnace?
Once a year, ideally in early fall before heating season, keeps an Ottawa furnace running safely and helps hold the warranty. Air conditioners benefit from a spring check.
Is a heat pump worth it in Ottawa?
Modern cold-climate heat pumps heat efficiently well below freezing and pair with a furnace or electric backup for the coldest days. Whether they pay off depends on your energy rates and available rebates; ask for a payback estimate.
How long does a furnace last in Ottawa?
A well-maintained furnace lasts about 15 to 20 years in Ottawa. If yours is near that age and needing repairs, ask whether replacement is the smarter spend.
