AC Services We Offer in Ajax
Air Conditioner Repairs
Running but not cooling, cycling on and off, tripping the breaker, or dead in a heat wave? We diagnose it same or next-day. In Oshawa’s older homes, the culprit is often leaky ductwork or an aging system working too hard, and sometimes it’s a simple capacitor or refrigerant fix. We find the actual cause, explain it, and repair it when repair makes sense. We don’t upsell. Call 905-240-6055.
Our Diagnostic Service Calls are $135+HST. Parts and Repairs are extra.
Air Conditioner Sales and Installation
We offer free no-pressure, in-home AC installation consultations in Oshawa.
We size it to what your Oshawa home actually needs, factoring in duct condition and layout, not a generic square-footage number. You’ll get clear options and honest guidance so you can pick the right fit for your home and budget.
Central Heat Pump Cooling
A heat pump handles both heating and cooling from one system and can lower operating costs for the right Oshawa home. Certain systems and homes may qualify for Ontario government grants. We’ll assess honestly whether it fits your home, what backup heat you should keep, and whether your ductwork and insulation need attention first, which matters in Oshawa’s older housing stock.
Ductless Heat Pump Split Systems
Ductless split systems don’t need ductwork, so they’re perfect for Oshawa’s older homes, finished basements, or any room that’s tough to keep comfortable.
They heat and cool from one system, and we’ll lay out the honest pros and cons so you can decide with confidence. No pressure.

Aeroseal Duct Sealing For Uneven Cooling and Airflow
AC running non-stop but rooms still feel warm, or the second floor never cools? In older Oshawa homes, ductwork can leak a large share of your cooled air before it reaches you. A bigger unit won’t fix that. We check dampers and connections first, then assess whether Aeroseal Duct Sealing is right for you.
It seals up to 90% of ductwork leaks in one visit, includes whole-home duct cleaning, and works from the inside out.
