    What Our Ottawa HVAC
    Customers Are Saying

    Our furnace broke down a few days before New Year’s. I called Dion Comfort and they immediately dispatched a technician. We were up and running in no time at all. Excellent service! Thank you!

    Rolland M.

    The service afforded to us as new home owners (facing a modest heating emergency) by that of Dion Comfort and specifically the controller (Dee) and onsite technician (Malcolm) was beyond superb.

    I caught myself thinking on multiple occasions throughout our emergency request and fulfillment thereafter how incredibly proactive, transparent, efficient and effective these representatives of Dion Comfort were and the level of genuine care put forth in our favour.

    We entered this nightmare scenario on edge, anxious and perplexed. Dee and team were able to provide us with peace of mind nearly immediately upon our service request and not only did so but delivered on their assurances in spades.

    I/we would highly recommend Dion Comfort to anyone seeking HVAC services, they have gone well beyond the call of duty for us and as a professional in client relationship managing it is obvious that this was not a one off scenario, they are truly vested in the best interest and outcome for their clients.

    Our sincere gratitude and thanks to Dion Comfort, Dee and Malcom.

    Replaced both our AC and furnace with Dion. They did a very neat job, very professional. I contacted them about a few details and they quickly came to touch up those concerns. Excellent service and fair pricing. I would gladly recommend to friends and family!
