Whitby AC Services
Expert Air Conditioning Installation for Whitby Homes
Whitby has grown fast over the last two decades. What started as a small lakeside town is now a sprawling Durham community with over 130,000 residents across Brooklin, Williamsburg, Rolling Acres, Pringle Creek, and the original downtown core. That growth means a huge mix of housing — from pre-war cottages in Port Whitby to 3,500 sq ft executive homes in Brooklin — and each needs a different cooling approach.
We install central AC and ductless mini-split systems across all Whitby neighbourhoods. Central AC is the best choice for homes with existing furnace ductwork — it provides whole-home cooling at a consistent temperature through your existing vents. For pre-1990 homes in Downtown Whitby and Port Whitby that lack ductwork, ductless mini-splits are the practical alternative, avoiding the $5,000 to $10,000 cost of installing new ducts.

Common Questions
AC Installation Whitby — FAQ
How much does AC installation cost in Whitby?
Central AC installation in Whitby typically runs $3,500 to $5,500 depending on system size, SEER rating, and any ductwork modifications. Ductless mini-splits start at $3,000 for single-zone and $6,000+ for multi-zone. Larger Brooklin homes above 2,800 sq ft may need a 4 to 5 ton unit. Free in-home estimates with transparent pricing.
What size AC do I need for my Whitby home?
Most Whitby townhomes and 1,200-1,500 sq ft bungalows need a 2 to 2.5 ton unit. Two-storey detached homes in Williamsburg or Rolling Acres (2,000 to 2,800 sq ft) typically require 3 to 3.5 tons. Executive homes in Brooklin with 3,000+ sq ft often need 4 to 5 tons or dual-system configurations. Our Manual J load calculation confirms the right size on every free estimate.
Should I choose central AC or ductless for my Whitby home?
If your home has ductwork from a forced-air furnace, central AC is usually the most cost-effective choice. For older Port Whitby and Downtown homes without ducts, ductless mini-splits avoid the $5,000+ cost of adding ductwork. Some Brooklin homeowners pair central AC on main floors with ductless units in finished basements or over garages.
How long does AC installation take in Whitby?
Most central AC installations are completed in one day — typically 4 to 8 hours. This covers setting the outdoor condenser, connecting refrigerant lines, electrical wiring, thermostat setup, and full system testing. Ductless mini-split single-zone installations take 3 to 5 hours. Multi-zone ductless systems may take one to two days.
Can I get a rebate on a new AC in Whitby?
Not on the AC itself — only cold-climate heat pumps qualify for Ontario’s Home Renovation Savings rebate, not standalone air conditioners. Swapping your AC for a cold-climate heat pump gets you cooling plus heating and can qualify for up to $7,500, with the most going to oil-, propane-, or electrically heated homes (gas-heated Whitby homes qualify for less). The rebate is filed by a program-registered contractor, so confirm your installer’s status. We also offer Enbridge Sustain $0-down financing on new systems.
