Minimize downtime and increase the comfort of your work environment
An HVAC system you can trust
The last thing you need to think about is a malfunctioning HVAC system. Endless repairs and inept installations cost you time, money and energy, all while making your work environment unpleasant.
DonAir has been keeping our clients and their employees comfortable for over 27 years by installing, repairing and maintaining heating, ventilating and air-conditioning systems for commercial and industrial use. Our fully-licenced technicians install only the best products and carry most parts and accessories needed for any job in our well-stocked trucks – all in the effort to reduce your company’s downtime.

Don’t make your customers sweat. Let DonAir help you keep your cool with a premium air-conditioning system.

Tired of shivering your way through winter? DonAir can warm you up to the idea of stable heating even through the most frigid temperatures.

Need a breath of fresh air? DonAir installs efficient ventilation systems for commercial and industrial use.
Quality Installation
Unless you’re investing in quality HVAC equipment, all you’re getting is a potential problem down the road. Our licensed specialists install only the highest-quality, dependable equipment so you get a hassle-free system.
Dependable Maintenance
Worn-out equipment not only breaks down more often, but it’s also more inefficient, leaving you with higher bills and more worries at the end of the day. We offer preventative maintenance that will keep your clients and your employees comfortable through every season.
Quick turnaround and Repairs
You need the repair done now, not when the part comes in. We keep our vans well-stocked, so when your HVAC system breaks down, we don’t need to get the part – we already have it.
We service Orillia, Barrie, Hamilton, Peel, Durham, Toronto, GTA, Oshawa and everywhere in-between!
Service you can trust with your business
You need to partner with people and companies who you’re confident can keep your business running smoothly.
At DonAir, we pride ourselves on establishing strong relationships with each of our clients. That means more than just providing service and products you can trust. We believe strong communication is key to giving our clients exactly what they need when they need it. This is our commitment to you.
