What does central air conditioning cost in Brockville and Kingston?
Expect $3,000–$8,500 installed for a central AC system, with the Ontario provincial average for a 2-ton unit landing around $5,500. Price depends on tonnage (system size), SEER2 efficiency rating, and whether existing ductwork can be reused.
What's the difference in cost between central air and a ductless mini-split?
Central air costs more upfront if ductwork is already in place, but a ductless mini-split often costs more per square foot of coverage because each zone needs its own indoor unit.
| Central Air (ducted) | Ductless Mini-Split | |
|---|---|---|
| Best for | Homes with existing ductwork | Additions, homes without ducts, room-by-room control |
| Typical installed cost | $3,000–$8,500 whole-home | $3,000–$6,000 per zone |
| Install time | 4–12 hours (single day) | Half day to 1 day per zone |
| Efficiency | Good; whole-home even cooling | Excellent for targeted zones |
| Rebate eligibility | Standard AC — generally not rebate-eligible | Heat pump models qualify for Ontario HRS rebates |
What factors change the price of my quote?
The biggest swing factors are home square footage, whether ductwork needs modification, electrical panel capacity, and system efficiency tier. Add-ons like a smart thermostat or new filtration typically add a few hundred dollars, not thousands — get these itemized separately in any quote.
How long does AC installation take and when should I book it?
Most single-system installs are completed in one day, from as little as 4 hours for a straightforward swap up to 12 hours for a full install with ductwork changes. Book in spring, before the summer demand rush — contractors across Eastern Ontario report tighter scheduling June through August.
