Why HVAC Maintenance Matters in Ontario

Ontario temperatures range from -30°C in January to +35°C in July. Your heating and cooling system works harder here than almost anywhere else in Canada. Skipping annual maintenance shortens equipment life by 30–40% and voids most manufacturer warranties. A $195 tune-up today prevents a $4,000 furnace replacement in three years.
