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.

Had Aire one install a new system. The service and installation were amazing. Great experience provided by Pat and Daniel. They explained every detail as I had questions about operations. They didn’t hesitate to stop working to answer my questions.

Jacob Abraham

Pat and Daniel replaced our furnace and tankless water heater and softener today. They finished the work professionally within the short time. They took all the scrap stuff. They both were polite and friendly.

ZAINAB SHAIKH

I recently replaced a leaking water heater and some aging valves. AirOne has provided me with a great experience. I had the pleasure of working with Marco, Judson and Matthew for the issues with the valves, Chris Klisouris who provided me with a fair quote for the water heater and then Kyle + Matt, installed the unit. Thank you for making this issue as painless as possible.

Tom Herr

Hasan, Darren and Jason arrived to service my hot water heater today and was excellent!! He was very thorough and explained to us what was needed and why!

Leah MacLeod

Big shout-out to Randy Ryan and his team! They installed our new AC today and the experience was fantastic from start to finish. Randy is a real pro—you can tell he’s incredibly skillful. I wholeheartedly recommend him. You won’t be disappointed! Five stars, without a doubt!

Ajay Lenin

We are pretty happy with Jose and Hasan’s amazing team work and professionalism. Huge thanks to Alex McDermott for his quick and efficient help! He identified the issue with my furnace within seconds. Incredible service and responsiveness!

Bill, Flo and Edwardo came to service our AC and furnace today. The team really made the whole process really smooth. They took the additional time to put down mats to prevent damage to the floors. They explained everything really well – we love how cold the house gets!!

Adam E

I wasn’t sure what to do about my humidifier because it was very old. Tarinder came by and showed me exactly what was wrong and why it won’t work anymore. I felt confident because even if it couldn’t be fixed the cost of the service call didn’t go to waste. I can put the cost towards the new unit I need.

Keehan Koorn

Excellent company with friendly knowledgeable service techs and supportive in office staff. They servuxe your needs. I have the gold star maintenance plan which has been a great value for years!

Diane Inkster

I scheduled a system tune up and Pat and Dan showed up early morning, they were quick and efficient. Super respectful and tidy. Really appreciate the thorough inspection

Gloria Leung

Pat and Owen installed my A/C, tankless water heater unit and thermostat. They also removed my existing water heater. Their service was exceptional and professional. Great job guys thanks.

Dante McKenzie

Just awesome service. The phone calls are friendly, they came out right away. Dave C quickly figured out the issue, (snow covering the vents…duh) and made my night. Now we’re getting heat and I am thrilled. Thank you so much!

Joel Robinson

Bill and Eric were great! Super helpful and efficient. Would definitely recommend going to this company. Very quick and well done they did a great job installing and explaining how to use the high tech thermostat.

Should I replace my 20-year-old AC?

If your AC is 20 years old, it’s likely less efficient and more prone to breakdowns, using outdated technology like R-22 Freon, which is no longer produced. Replacing it with a modern, energy-efficient unit can save on energy bills and repairs.

Is a window AC or central air more cost-effective?

Window AC units, costing $150–$600, are cheaper upfront and ideal for small spaces or homes without ductwork, but they’re less efficient for whole-home cooling. Central air systems ($3,500–$8,000 installed) are more cost-effective long-term for larger homes due to better energy efficiency and even cooling.

How long do air conditioners and furnaces last?

Central air conditioners typically last 15–20 years, while furnaces last 15–25 years with proper maintenance. Regular tune-ups can extend lifespan, but older units may lose efficiency or require costly repairs.

What size AC do I need for a 1,500–2,000 sq. ft. home?

For a 1,500–2,000 sq. ft. home, a 2.5–3.5-ton AC (30,000–42,000 BTUs) is typically recommended, depending on insulation, climate, and home layout. A Manual J load calculation by a professional ensures proper sizing.

What does BTU mean, and why does it matter for AC sizing?

BTU (British Thermal Unit) measures the heat an AC can remove per hour. For example, a 1-ton AC removes 12,000 BTUs/hour. Proper BTU sizing ensures efficient cooling without overworking the unit, which can reduce lifespan or increase energy costs.
