Daikin is the largest heating and air conditioning manufacturer in the world and has won the ENERGY STAR Most Efficient Product award for three years in a row in Canada. With a commitment to innovation, quality and technology, Daikin is a brand that A1 is proud to install.

Genius is a more affordable option but also has all the modern features you want and the reliability you need. The Genius line of high-efficiency HVAC products is so good, we put our name on it – Genius is our very own signature brand.

A1 did what they do best and satisfied our needs. In this case, they recently overcame the COVID related parts supply chain stocking issues and found a difficult to find replacement part to fix our A/C system and just in time for the hottest day of the year! A1 has been consistently exceeding our expectations as our HVAC service/systems supplier for over 12 years now and we do not hesitate to recommend them.
