AC installation in Whitby, ON
Owner-operated, properly sized, and done right the first time. Beat the Whitby summer heat with a new AC system from a licensed Durham Region technician with 15+ years experience.
AC installation by someone who actually knows Whitby
Whitby summers are hot and humid, a properly sized AC system isn't a luxury here, it's a practical necessity. Whitby's housing stock spans older homes near the historic downtown core and Lynde Creek to newer builds in Rolling Acres and Pringle Creek. Zack has been installing AC systems across Whitby for over 15 years and knows what each neighbourhood's homes typically need.
Proper sizing
An oversized AC cools too fast and doesn't dehumidify. Undersized and it never keeps up. We calculate the right size for your home, not just what fits.
You own it outright
No rental contracts, no monthly fees, no surprise clauses when you sell. Every system we install is yours, maintained on your schedule.
Single-day install
Most central AC and ductless installations are completed in a single day. We leave the work area tidy and the system fully tested before we go.
Honest recommendation
If a heat pump would serve you better than a straight AC replacement, we'll tell you. No pressure toward the more expensive option.
What we install
The right system depends on your home's size, age, and existing setup. Here's what we carry and install:
Central AC (ducted)
Homes with existing ductwork looking for whole-home cooling. The most common installation in Oshawa, efficient, quiet, and effective for hot humid summers. We prefer Rheem WeatherKing but install all major brands.
Ductless mini-split
Additions, garages, basements, or older Oshawa homes without ductwork. Individual room control, no major renovation required, installed in a single day.
Heat pump as AC replacement
If your AC is due for replacement, a heat pump delivers the same cooling plus efficient heating, often at a comparable cost and eligible for HRS rebates. Worth considering before replacing like-for-like.
New build / first-time install
Adding central AC to a home that's never had it, or a full system for a new build. We assess your ductwork, load, and layout before recommending anything.

We come to your home, assess your space, and give you a written quote with transparent pricing. No phone estimates. We need to see the home to size the system correctly.
Honest system recommendation
We recommend the system that's genuinely right for your home and budget, not the most expensive option. If a heat pump would serve you better, we'll tell you.
Installation, typically one day
Clean, careful work. Most central AC and ductless installations are completed in a single day. We treat your home with respect and leave the work area tidy.
Testing & commissioning
We test the system thoroughly before we leave and confirm it's cooling properly. No guesswork, the system has to perform before we close up.
Walkthrough & ongoing support
We walk you through the new system, explain thermostat settings and filter maintenance, and answer any questions. If anything isn't right after we leave, call us.
What Whitby customers say
"Zack rescued us last summer and rescued my mother and brother this summer! Respectful, responsive, and reasonable, kind and considerate. We would recommend HVAC Zack over and over again."
A note from Zack
The best time to think about a new AC is before the heat hits. April or May, when we can take the time to look at your home properly and recommend the right system without urgency driving the decision.
I've been installing AC systems across Whitby for over 15 years, from the older homes near the downtown core to the newer builds in Rolling Acres. Getting the sizing right matters more than the brand. Call me and we'll figure out what makes sense for your home.
