What Ottawa Homeowners Should Know
Our climate puts unique demands on HVAC systems:
Winter: Furnaces run 6+ months per year — efficiency and reliability matter more here than in milder regions
Summer: Hot, humid summers mean your AC works hard too
Temperature swings: -30°C to +35°C means your equipment handles extreme range
Housing stock: Ottawa has everything from century homes to new builds, each with different HVAC needs
Local codes: TSSA licensing and City of Ottawa permits are required for most HVAC work
Making Good Decisions
When choosing equipment: - Focus on proper sizing (bigger isn't always better) - Compare efficiency ratings (AFUE for furnaces, SEER for AC) - Consider total cost of ownership, not just purchase price - Check available rebates before deciding
When choosing a contractor: - Verify TSSA licensing (legally required) - Check insurance (WSIB coverage) - Read Google reviews (look for patterns, not outliers) - Get 2-3 written quotes for comparison - Ask about permits and inspections
Common Questions
How long should my equipment last? Furnace: 15-25 years. AC: 12-18 years. Heat pump: 15-20 years. With proper maintenance.
When should I replace vs repair? Generally, if repair cost exceeds 50% of replacement cost on equipment over 12 years old, replace.
Do I need permits? Yes — TSSA inspection is required for all gas work. City permits required for most installations.
Should I get a maintenance plan? For equipment under 15 years old, annual maintenance pays for itself in efficiency and prevented repairs.
The Bottom Line
Being an informed homeowner is your best defence against overpaying or making poor HVAC decisions. Take the time to understand your options, and don't rush major purchases.
