Excellent knowledge and service
Silvio and Dominic did a great job. They always showed up when they said they would and did it all on the hottest days this summer.
My experience was amazing. I called Sunny at City Air who sent Sylvio to look at my air conditioner. Sylvio arrived and explained my different options of which I decided to purchase a replacement unit. The work went well and my home is cold. Thank you all at City Air for your help and expertise Julius from ScarboroughService: Install AC
