Our customers are the biggest part of our company story. Many of our customers stay with us for many years – we take that as a compliment. Some even bake cookies for us! And we are grateful for that patronage, but never take it for granted.

Our strong work ethic and high standards mean that all A1 customers get the very best products, service and installation in the business. We stand behind everything we do.

Our expert A1 Technicians are triple-certified – all our customers benefit from this top-of-the-line training. Better equipment. Better installations. Our Technicians are long time A1 employees – we never use contractors.

Yes, our core business is about heating and cooling the air in your home, but we also provide expert advice on products to improve the air quality in your home – clean air is better air. We can help you learn more about air purification, fresh air ventilation and UV lights to remove bacteria and viruses.

And when you need us, we’re here. When you call A1, a real person will answer the phone. Our third-generation owner Peter Messenger has been known to make service calls on Christmas morning. We have a can-do attitude that is reflected in every single one of our employees. This is who we are.

So, take the next step and give us a call so we can get to know you. Get closer to having that perfect temperature, humidity just right and air that is clean and filtered to help you stay healthy and happy.

Own your air. We can help.

The history of A1 Air Conditioning and Heating

Walter Messenger first learns about refrigeration during WWII as a royal engineer tank mechanic for the British army. After the war, Walter is hired as a London bus mechanic.

1940-1950s

Walter and the Messenger family immigrate to Canada and Walter decides to open his own business. A1 Air Conditioning & Heating is born.

1960-1967

Walter’s son Paul Messenger joins the Canadian navy to work as an aircraft mechanic. After finishing his service, Paul returns home to enroll in the very first refrigeration class held at Mohawk College in Hamilton, Ontario.

1968-1974

A1 moves its head office into the original Township of Trafalgar office building on Chartwell Road in southeast Oakville. Upon Walter’s retirement, Paul takes over the family business.

1980-1982

A1 creates the SuperCare Protection Plan program, the first of its kind in the industry, providing customers with the opportunity to enroll in an annual maintenance program offering yearly tune-ups and other included services.

1984

A1 expands its product line to include indoor air quality products, including air purifiers, ventilators and humidifiers. Paul’s son Peter seeks to continue the family business by achieving licenses as a gas fitter, electrician and refrigeration mechanic.

1989

A1 offers a revolutionary 10-year warranty, including parts and labour, on all its installations. This industry-leading warranty is the first of its kind in southern Ontario.

After years of offering a vast range of HVAC brands, A1 becomes the first Daikin dealer in Canada. Daikin’s commitment to innovation, quality and technology lines up perfectly with our A1 values. Founded in 1924 in Japan, Daikin is the largest heating and air conditioning manufacturer in the world.

2013
