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: $129Commode Supply (aka, the cost of the job): $92Total: $221Yeah, 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.

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.

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.

I've been a member for several years now of their "Comfort Club" program. Purchased a new furnace and A/C through them. I usually call in around this time of year to schedule my included (paid for) A/C maintenance and they're telling me they can't come out until August, which at that time of summer, what's the point? No email, text or phone call reminder to schedule. I would think that repeat customers be treated with more priority.

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!

Temp was dropping lower than temperature set point. Tonna Mechanical came out and diagnosed problem was air in the line from the hot water heater. We have a high velocity system that uses hot water from the hot water system to heat the home. They bled the hot water heater to get rid of the air in the line. That solved the problem. Special thanks to technician Jamie Bicknese. Jamie diagnosed the problem and took the time to explain how it happened and how to prevent it happening in the future. He was extremely helpful, polite and knowledgeable. We’re members of the Comfort Club, a very good value in my opinion. We’ve been using Tonna Mechanical for years and have never had a bad experience.

Corey was prompt, professional, and knowledgeable. He explained everything he would be doing, provided updates during the process, and offered recommendations for future service. Outstanding experience! I wouldn’t hesitate to call Tonna again for service on my furnace. Highly recommended!

Arron was very knowledgeable even though Tonna doesn't carry my furnace's brand and the installation is very "unique". He was the friendly, professional, courteous tech I have come to expect from visits from Tonna.

Tonna installed an Carrier Infinity Furnace in our home today, replacing our 35 year old one. Our Tonna installer Jacob worked non stop, diligently until the installation was complete. Jacob answered all our questions, explained everything in detail perfectly and professionally. Dan worked worked with us all through the estimate and installation process, thank you Dan for all your patience. Tonna delivered again 5-Star Service from beginning to end. 🌟🌟🌟🌟🌟In addition to Tonna installing our new Carrier furnace, Tonna also cleaned all our HVAC ducts. Wyatt, the Tonna technician, was respectful and professional while cleaning our ducts. After he finished the duct work, he cleaned up any mess, as if he had never been there. We were very impressed and pleased with Wyatts work, thank you 🌟🌟🌟🌟🌟

My garage furnace had a cracked heat exchanger and needed replacing. Kyle installed a new one yesterday and it is amazing! Excellent installation and it looks great! Had to have an electrician come to the house to finish wiring, and was completed the same day. Another amazing job by my friends at Tonna! Will continue using them for all my heating and cooling needs. Thank you Tonna and Kyle!Service: Heating system installation

I had ordered a dual head replacement shower head and valve from a big box store. Jeremy expertly assessed the situation, explained that installation would be a significant project, and pointed me toward more economical options. This outfit is truly professional. 5 stars.

Mr. Zimmerman is a very personable, professional, knowledgeable and right down good guy.We absolutely love his service. We have had him as a technician in the past, but we felt he deserves some extra recognition this round.Aaron really does go above and beyond for the call of duty.

Jamie is clearly very knowledgeable and enjoys his job -- a winning combination. Explained the physics of the machinery and made a few "tweaks" to improve its efficiency. A new employee, Ella, was working with him, and she fixed a problem with my Carrier app that the central "help desk" was unable to solve. Overall, excellent service.

Rob was very efficient and we discussed the settling of our air conditioner outdoors. I also love the new furnace filter he installed. I absolutely HATE dusting and my husband has some seasonal allergies. If this helps both of us we will really have to thank Rob again!

I am so impressed with this company. The person that answers the phone the times I have called represents how wonderful the talented personnel are behind the scene. I have had three quotes from them and am trying to install their suggestions as I can afford. We had them install a heated house humidifier for the winter, This has made so much difference in our static as well as our breathing. The dust actually seems to be less with it as well. I like integrity and we have found that to be the case with the people we have had the privilege to work with.

The service was fine. But I have not dealt with such a condescending, rude, and secretive customer support team in my life. I would never do business with this company again. All I asked for was a simple explanation of a bill that I had already paid and they bent over backwards in at least five different emails to not answer my questions. Finally they basically told me to get lost and that I wasn't needed as a customer any longer. Conveniently waiting until after they charged me yet another monthly service fee to their maintenance club. I am absolutely dumbfounded. All I wanted was some explanation to the charges on my bill that I had already paid. I just wanted to know what I had paid for.

These guys are amazing!! I used them for duct cleaning in September and now I just had them replace my furnace. My furnace died in the middle of the night when it was -11 degrees out and they responded immediately! They had me toasty warm by the next day! Their professionalism and customer service is fantastic! I can't recommend them enough.

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 had a great experience with an AC and furnace replacement with Tonna. The installation was much quicker than I expected. The guys who did the work were friendly, efficient and very respectful of my home. Would 100% recommend.Services: HVAC system repair, HVAC system maintenance, A/C system maintenance, A/C system repair

Kyle was prompt, friendly and informative. I appreciate that he took great care as he came in/out of the house carrying parts and equipment, as well as leaving the work area clean. Tonna is fortunate to have him on their team!

I am very pleased with the service and care provided by Jeremy. He helped me deal with a minor problem and a more serious problem. He did a beautiful install for my sink and fixed a leaky pipe that was a surprise in the day.

I contacted them for an estimate to replace a toilet and they said they needed to see it before giving me one. To do this they HAD TO CHARGE a FEE just to give me an estimate. If I chose to "join" their club, then the fee would be waivered. I contacted other business for an estimate that they could do over the phone for free.Talk about nickeling and diming the customer.

I called four different companies to get quotes about cleaning my air ducts. The first three people were so crabby! Tonna was great from the beginning. The lady on the phone was so nice and very helpful so I looked no further.A week later the Tonna tech (Wyatt) came out and was so nice and explained everything from the very beginning on what he was doing. He was great. Cleaning the furnace and dryer vent was included. The price was very reasonable. I would highly recommend using Tonna.

Jamie is very knowledgeable and gave me the facts I needed to make an informed decision. Getting the straight truth is much appreciated…. Jeremy did a great job of replacing toilet, working great. I had previously left an unkind review, a misunderstanding on my part in regard to cost Cindy in the office guided me through and went the extra mile for me. Thank you, your help made my day!! Rob inspected my a/c today and gave me tips on how to more efficiently use the furnace that was installed a short while ago. Ensured that all was running properly. Very courteous and knew his stuff. Two thumbs up to Tonna and Rob!Wyatt cleaned my ductwork today, neatly done and cleaned up after this messy job. All vents back on and clean. Thanks Wyatt great job. 👍🏻

Big, big thanks to Caleb, who diligently investigated and showed his detective skills to find the source of our low water pressure issue. He was kind, showed great customer service and explained what was going on or what he was thinking along every step of the way. He delivered great work installing the new water softener (which had caused the problem). Thanks!

Tonna responded promptly when our water heater stopped working. Hunter was great - knowledgeable and personable. He explained the issue, and how he was going to repair it. And then he promptly completed the repairs. Al and I would highly recommend Tonna.

We are very satisfied with our new Carrier equipment.Jacob also did an excellent job installing a Broan Air Exchanger in a very timely manner.We are very satisfied with this new equipment!
