    5 star review  Old furnace died in the new year holidays, as all the shops were closing, during covid lockdown. I didn't have much hope it could get fixed or replaced any time soon. Called City Air Toronto, and Sylvio came that day, assessed the situation and gave me the repair versus replace options. He was able to replace it and have the heat back on, so the kids could sleep warm, that very night.

    5 star review  Originally called Reliance Home Comfort for A/C relocate as they are who installed the unit back in 2016. Reliance gave us a huge runaround. Spoke with Sunny from City Air on Monday and Julian was at my home Wednesday Morning. Julian was so professional and polite. It has been a pleasure dealing with City Air and our unit looks great. Julian left the workspace spotless. 100% Recommendation, we will be calling City Air for all of our heating-A/C and Duct work from now on!!

  • 5 star review  I called to get a quote and they sent someone over in less than 2 hours. The owner (Sunny) was very helpful and kept me fully informed and updated every step of the way. Julian is an amazing installer. He worked efficiently with Matt and was respectful about keeping my house clean. I would recommend them to anyone that wants fast and friendly service.

    5 star review  My father-in-law's air conditioner wasn't working the first really hot day of the summer. I called City Air Toronto after seeing their favorable reviews on BBB. The technician, Enrico came over within an hour and quickly troubleshoot the problem to be a blown capacitor in the outside compressor unit. He had to go back to the warehouse to get a replacement part but returned very quickly to repair the A/C. He was very courteous and explained the problem professionally. The total repair bill was very reasonable and matches exactly as their posted rates. I will definitely use them again if I need A/C or heating service.
