Sub Zero Technical Ltd. Family owned and operated. We have been serving Calgary since 1995.

We’re experts in commercial HVAC systems. ✅

No two buildings are the same, and commercial setups are almost always custom, designed around your layout, occupancy, equipment needs, and controls.

That’s why experience matters. We have the knowledge and expertise to install, repair, and maintain commercial systems so they run reliably, efficiently, and with minimal downtime.

Summer tends to ramp up fast in Calgary, and once the first real heat wave hits, install and service schedules fill up quickly. ☀️

If you’re thinking about a new A/C or you want to make sure yours is ready, now’s the time to book an install or tune-up.

A pre-season check can improve performance, help avoid mid-summer breakdowns, and keep your home comfortable when it matters most.

HVAC is a lifestyle. ❄️☀️
