We had a new furnace/AC unit installed this month. From start to finish, Tonna was great to work with. I would highly recommend them when considering an HVAC company in Rochester. A+

Working with Tonna was a breath of fresh air after my experience with another HVAC place in Roch. Tonna was always super professional, they spent at least a half hour getting information and measurements to quote a complete new system. Never tried to upsell me. They also have a very good process and outstanding communication for a company like this. Install was really smooth, on time, and looks really good. Prices were fair and honestly I just never thought I could have such a good experience with an HVAC company. Keep training your tech well, it shows!!!

We called Tonna when our air conditioning unit went out at the beginning of the summer. My husband knew it needed replaced and they sent a representative within the hour who gave us all the options as well as added some refrigerant to help us get by. We priced a couple of other companies and Tonna’s was the most competitive. We chose the package to replace the furnace along with the air conditioning. Everything was completed within a week. Thanks Tonna for a very easy and seamless experience!
