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. (Serving Markham, Ontario.)
