The Heating, Ventilation, and Air Conditioning system that controls a home's temperature and air quality. In Ontario homes, this typically includes a furnace (gas or electric), an air conditioner, ductwork, and possibly a heat recovery ventilator (HRV). HVAC systems have a lifespan of 15 to 25 years for furnaces and 10 to 15 years for air conditioners.
Why It Matters
HVAC is one of the most expensive systems to replace -- a new furnace and AC can run $8,000 to $15,000+. During an inspection, check the age, maintenance history, and efficiency rating of the system. Also find out if any equipment is rented (a common practice in Ontario that comes with transfer obligations).
Real-World Example
You are buying a detached home in Mississauga and the inspection reveals the furnace is a 22-year-old mid-efficiency model and the air conditioner is 16 years old. Both are beyond their typical lifespan. The home also has a rental hot water tank from a third-party provider with a buyout cost of $1,200. You estimate $10,000 to $14,000 to replace the furnace and AC, plus the water heater buyout. You negotiate a $12,000 price reduction to offset the near-term replacement costs.
Ontario & GTA Context
Ontario has unique HVAC quirks that buyers should know about. Rental water heaters and furnaces are common -- companies like Enercare and Reliance place equipment in homes under long-term rental contracts that transfer to the new owner on purchase. The buyout costs can be $2,000 to $5,000 or more. Additionally, Ontario's building code requires carbon monoxide detectors near all sleeping areas in homes with fuel-burning appliances, and all furnace replacements must meet current high-efficiency standards.
How It Works in Practice
During the inspection, ask about the age of the furnace, air conditioner, and water heater. Check whether any equipment is rented and what the transfer or buyout terms are. Factor these costs into your negotiation. A furnace and AC replacement typically costs $8,000 to $15,000 combined. Getting quotes from multiple licensed HVAC contractors is recommended.
