  • 5 star review  I have an old water boiler heating my home, and every other company I called insisted on installing a new system. Some of these solutions were priced upwards of $15,000, or were contract based with a monthly fee of close to $200 on a 10+ year term. Sonny (the owner) came by and immediately recognized that the water pump was broken, and had Silvio (his employee) fix it the next day. Silvio also identified which parts to replace in the future, should any others break down. I can't recommend Sonny's company enough, and will be referring him in the future.

    5 star review  We have always used City Air Toronto Heating & Air Conditioning for our 100 year old building furnace which they continue to have running. They are very knowledgeable and experienced and can repair and troubleshoot the problem quickly-- Sylvio repaired our furnace and it works like brand new.

  • 5 star review  Sylvio came out to relocate my AC unit. I didn’t have levelling gravel so he picked some up at a landscaping store and laid it down.l first. Came by on time and did a great job, cleaned my AC unit as well as there’s a dusty condo development happening across the street. He spoke with the neighbour and even cleaned their unit for free. Great service…he really cared about doing a good job. Above and beyond.

    5 star review  When our AC blew in the middle of July, these guys really saved us! They were on site within 3 hours of the initial call, and were able to give us a thorough breakdown of what our issue was. We ended up needing a whole new AC unit, and they were able to have a new unit installed within 24 hours of the initial visit. The price is super affordable given the quality of service, and the quality of the unit installed at our home! They were quick, efficient, and so kind. Any questions or concerns we had were handled with ease and guarantee. I would highly recommend this company to others who are in need of these services! Will definitely be calling them with any HVAC needs in the future.

    5 star review  I am extremely pleased with the services they offer. They were super quick and helpful with fixing heating issue in the middle of winter when the main competitor wasn't able to help at all for several days... Now I am working with them every time I need, super reactive. Take time to explain and discuss. Good price and quality. Silvio is super nice and professional. I am so glad I found them! Totally recommend them.

  • 5 star review  A 16 year old furnace at a rental stopped working the other day. I called City Air and they dispatched the technician. Sylvio was onsite in Newmarket quickly and reported the furnace was not worth repairing given its age and he recommended replacing it. He also mentioned he had recently purchased a dented furnace at a discount clearance and would sell it to use for $600 off discount. I approved the work and Sylvio had the replacement in and everything cleaned up early evening. He also cleaned up the gas pipe that ran from the furnace to the water heater to give us more room to move around at no charge. The next day I called him asking for a little cleanup of the expanding foam and caulking where the exhaust piping reached outside. Sylvio was back on site within an hour to do the clean-up. Very impressed with the quality of work, attention to detail, and the good price.

    5 star review  City Air was very thorough and professional with their work they did for me. Also the price was okay. I highly recommend City Air for anybody who needs a new furnace, furnace maintenance, or a new air conditioner for your home or business. They also did a great job servicing my hot water heater. And I like the fact that they put tarps down wherever they walk, so they left my house very clean.

    5 star review  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
