Does AC repair require a licence in Ontario?
Yes — refrigerant handling in Ontario requires TSSA certification (for gas-fired equipment) and EPA/Environment Canada certification for refrigerant work. Any company touching refrigerant must be properly licensed. Always ask for the technician's certification number.
AC repair vs replacement in Ontario
If your central AC is over 10–12 years old and needs a compressor or major coil repair, replacement is usually the better choice. A new central AC unit costs $3,500–$7,000 installed in Ontario, but comes with a 10-year parts warranty and 30–50% better efficiency than an older unit. For units under 8 years old, most repairs are worth doing.
