What Our Customers Are Saying

Troy did an amazing job! He was so knowledgeable and made sure that we were fully in the know of what he was checking. We feel so much more at ease knowing that our gas appliances are safe! I would highly recommend.

Ben Singer

Recently had a new furnace installed. Service was excellent; arrived on time, laid floor cover and were careful with install, answered questions and ensured we had the app all set up. Would definitely recommend.

Amanda Weber

Jugraj has been extremely professional and helpful in fixing a leak that I had with my floor heating system. Airone has been very prompt in responding to my emergency and I would certainly recommend them.

Dennis Varghese

We needed our water heater replaced. Kyle and Matt explained options and gave helpful advice on a replacement type. Aire One made time to install it promptly, which was appreciated. Overall a great experience.

John Webster

Completed an annual service on my natural gas furnace. Arrived on time, with text and email notice before arrival. Manpreet went above and beyond by also installing a filter on the air intake pipe at no extra charge. Very happy with the service!

Sarah Wilkins Laflamme

Incredible service and attention to detail, I really appreciate JOSÉ and James’ taking their time to do it right and consult us on the heat pump placement so as not to disturb our neighbours!

Ben Miller

Fantastic work replacing our 15-year furnace! We had our furnace and A/C replaced and are very happy with the result. We went with Aire One after friends of ours used them to have their furnace replaced and we saw their work.
