Tonna Mechanical: Heating, A/C, Water Treatment, Plumbing & Duct Cleaning 1440 Industrial Drive Northwest, Rochester, MN 55901

"Brian did a phenomenal job!! I am so impressed! He was very informative. He explained things thoroughly and at a level that I was able to understand. Everything from the layout of the piping to the placement of the unit he meticulously thought it through before he started and had great suggestions for the efficiency of the unit as well as convenience. He did a beautiful job with installation as well. Everything looks clean and organized!"

"We pay a monthly service fee to Tonna for furnace and air-conditioning. That turned out to be a good thing for us as our furnace went out on March 2. It was a Saturday and I can’t imagine what the service fee might have been if it weren’t for the contract. Tried two different parts on our furnace and got the second one to work. Fortunately, it was not bitter cold outside this weekend, but the temperature in the house was down to 61°. Skyler was there in less than an hour after we called. Very prompt service. The furnace is working again. Did not cost us a dime today. Thank you."

"I was very happy with the service provided. Jamie was very knowledgeable and let me watch the diagnostic process. Most importantly, he fixed my the problem with my heating, but he also made me feel comfortable and confident in what he was doing by explaining what he was doing. He seemed honest and trustworthy. He also gave me advice about my system unrelated to the problem and answered all of my questions. Scheduling also went smoothly, and I was so happy they had availability to come out quickly."

"Easy to work with. I have a very complicated heating system. (Boiler, hydro coil, indirect water heater, and in floor zone heat). They install a new water heater, 6 months later I had found out that the water heater would heat when the floor zones called for heat. They came back and fixed the issue under the install work at no charge. I appreciate the professionalism and dedication to do the job right."

"Update: Since I had such a good experience using them for our furnace I decided to call them when we had a leak from our toilet. I did feel silly when I learned it was just the water supply line from the value to the toilet but it was a busy week and I didn’t even have a chance to look at the problem. I knew the price of the service call, but I didn’t realize that the service call didn’t cover any of the labor or parts. If I had realized that I wouldn’t have used Tonna for such a small item. The breakdown: Service call: $129 Commode Supply (aka, the cost of the job): $92 Total: $221 Yeah, a big part of this is me not paying attention to the pricing model but I wouldn’t recommend Tonna for little things like plumbing repair. Find someone else or see if it something that really needs a plumber first. When I called to cancel my membership the customer service was wonderful, honestly a lot of this is on me for not understanding the pricing model. I was a member but since plumbing issues are rare and we replaced our furnace, it doesn’t make sense for us to pay $10 a month if it ties me to a company I won’t use because of the price. Just no one tell my dad about this experience, he would be so disappointed. —————- I recently had my furnace and AC replaced by Tonna. They were punctual, neat, and fast. I haven't had the system long enough to review that but the service has been amazing. The best thing about them is how they handle communication. They send an estimate, invoice and any communication via email, which is great when you dislike the phone. We were able to set up an appointment via text message, it is great! The also sent us everything we need for the various rebates. All I had to do was a couple pieces of information and mail it out."
