Is it cheaper to repair or replace my furnace?

If your furnace is under 15 years old and the repair costs less than 50% of replacement, repair is usually better. Over 15 years, or if you're facing repeated $500+ repairs, replacement with a high-efficiency unit saves money long-term and may qualify for rebates.

What is the difference between a heat pump and a furnace?

A heat pump moves heat from outside air (even in cold weather) and can both heat and cool. A furnace burns gas to produce heat. Heat pumps are more energy-efficient but may need a furnace backup below -20°C in Ontario winters. Many Ontario homeowners are switching to hybrid systems.

What questions should I ask before hiring an HVAC contractor?

Ask for their TSSA registration number, liability insurance and WSIB certificate, manufacturer certifications (Lennox, Carrier, etc.), a written quote with equipment model numbers, warranty terms, and references from recent Ontario jobs. Never hire without verifying TSSA registration.

Is the HVAC contractor licensed and insured in Ontario?

All HVAC contractors in Ontario must be registered with the Technical Standards and Safety Authority (TSSA) for gas work. Verify registration at tssa.org. They should also carry $2M+ liability insurance and WSIB coverage — ask for certificates before signing.

Do HVAC contractors need a TSSA registration number in Ontario?

Yes. Any contractor installing, servicing, or repairing gas-fired equipment (furnaces, boilers, water heaters) in Ontario MUST have a TSSA registration number. This is a legal requirement. Verify at tssa.org/contractor-search. Hiring unregistered contractors voids warranties and insurance.

How often should I service my HVAC system in Ontario?

Service your furnace annually in fall and your AC annually in spring. Regular maintenance extends equipment life by 5-10 years, maintains warranty coverage, and can reduce energy bills by 15-20%. Most Ontario HVAC companies offer maintenance plans for $150-$300/year.

What size furnace do I need for my Ontario home?

Furnace sizing depends on home square footage, insulation, window quality, and ceiling height. A 1,200-1,800 sq ft Ontario home typically needs 60,000-80,000 BTU. Oversized furnaces short-cycle and waste energy. A proper Manual J heat load calculation is essential.

How long does a furnace last in Ontario?

A gas furnace in Ontario lasts 15-20 years with regular maintenance. Heat pumps last 12-15 years. Central AC units last 15-20 years. Ontario's harsh winters can shorten lifespan if maintenance is skipped. Plan to replace at 15 years to avoid emergency breakdowns.

What is the most energy-efficient heating system for Ontario?

Cold-climate heat pumps (like Mitsubishi Hyper-Heat) are the most energy-efficient, using 50-60% less energy than gas furnaces. However, they perform best as hybrid systems with a gas furnace backup for days below -25°C. Geothermal heat pumps are the most efficient overall but cost $20,000-$35,000.

Should I get a smart thermostat with my new HVAC system?

Yes. A smart thermostat (Ecobee, Nest, Honeywell) saves 10-15% on heating/cooling bills, or $150-$300/year in Ontario. Many HVAC contractors include one with new installations. Enbridge offers rebates up to $75 on qualifying smart thermostats.

What HVAC brands are best for Ontario winters?

Top-rated HVAC brands for Ontario include Lennox (best efficiency), Carrier (best reliability), Trane (best warranty), and Daikin (best heat pumps). All are widely serviced across Ontario. Avoid unknown brands — parts availability matters when it's -20°C.

Can I finance a new HVAC system in Ontario?

Most Ontario HVAC contractors offer financing through programs like SNAP Financial or Financeit, with 0% interest for 6-12 months or low rates over 5-10 years. Enbridge also offers rental programs for furnaces and water heaters. Monthly payments typically run $80-$150.

What is a two-stage or variable-speed furnace?

A two-stage furnace has high and low settings, running on low (65% capacity) most of the time for quieter, more efficient operation. Variable-speed furnaces adjust continuously for maximum comfort and efficiency. Both cost $500-$1,500 more than single-stage but save 15-20% on energy.

Do I need ductwork modifications for a new HVAC system?

Possibly. Older Ontario homes (pre-1970) often have undersized ductwork that restricts airflow with modern high-efficiency systems. A duct assessment costs $200-$400. Duct modifications run $1,000-$3,000. Ductless mini-splits ($3,500-$8,000) are an alternative for homes without ducts.
