- What's the typical cost range for AC installation in Ontario?
- Central AC installation in Ontario typically ranges from $3,500 to $7,500, depending on system capacity, ductwork condition, and whether your 1979-era home requires modifications. Ductless mini-split systems cost $2,000 to $5,000. Homes with original ducts may need upgrades, adding $500–$1,500 to the final bill.
- How do I know if my Ontario home needs a full AC replacement versus repair?
- If your system is over 15 years old, requires frequent repairs exceeding $1,200 annually, or uses R-22 refrigerant, replacement is usually more economical. Ontario's summer heat accelerates wear. Request a professional evaluation to compare repair costs against replacement—many contractors offer free assessments.
- Does Ontario's climate affect which AC system size I should install?
- Yes. Ontario's hot, dry summers require properly sized units to handle peak cooling loads efficiently. Undersized systems run constantly and fail prematurely; oversized units waste energy. HVAC professionals calculate tonnage based on square footage, insulation quality, and window orientation—critical for older Ontario homes with poor thermal envelopes.
