AC installation in Oshawa, ON
Owner-operated, properly sized, and done right the first time. Beat the summer heat with a new AC system from a licensed Durham Region technician with 15+ years experience.
AC installation by someone who actually knows Oshawa
Oshawa summers are humid and hot, the kind of heat that makes a properly sized, properly installed AC system a real necessity. Zack has been installing air conditioners across Oshawa for over 15 years, from older homes in Lakeview and O'Neill that are adding central AC for the first time to newer builds in Windfields and Kedron replacing aging systems. He prefers Rheem WeatherKing but installs whatever system is right for your home and budget.
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 Weather King 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.

What Oshawa customers say
"Zack is very professional and honest. I would not hesitate to refer him. His work is 5-plus stars and his prices set him apart from the competitors. He did an excellent job installing our AC."
A note from Zack
The best time to think about a new AC is April or May, before the heat hits and everyone is calling at once. That's when we can take the time to look at your home properly, talk through whether central air or ductless makes more sense, and whether a heat pump might actually be a better investment than a straight AC replacement.
I've been installing AC systems across Oshawa for over 15 years. The older homes in Lakeview and O'Neill often need a different approach than the newer builds in Windfields. Getting the sizing right matters more than the brand, an oversized unit cools too fast and leaves your home clammy. I'd rather measure your home and get it right than guess and have you living with a system that doesn't perform. Call me and we'll figure out what makes sense.
