Tonna sent a professional to my home to install a Water Softener and a Reverse Osmosis Water System. Both are from Hellenbrand name. The staff, Clint, had advised us about the effectiveness of a Water Softener and a Reverse Osmosis Water System before we ordered the systems. Both installations worked as scheduled and after installation, the staff advised us how to use the system more effectively. The prices were reasonable. Would hire again. In fact, our Water Heater was also installed by Tonna.

Jamie gave us the good news and bad news. They also did a refrigerant charge on my old unit to get us by until they were able to install the new AC and furnace. Also caught the need for grounding of our gas line to bring it up to current building code.

Excellent in every way I can think of. Exceptional knowledge of what a customer will benefit from, patient--even with an unreasonable inspector, These are people you want to work with! Worthy of your trust when you're not sure yourself what you need or what's best for you. (I don't give many glowing reviews!)

First visit (1/27/15): I had contacted Tonna to check the flame sensor on my furnace. the burner was cycling often. During the first visit the technician confirmed my suspicion that the flame sensor was bad. He also found that the drain for the exhaust fan was plugged and the burners were rusted (propane furnace). He cleaned out the drain. He also cleaned the flame sensor as best he could until he could come back with a new one. He was very careful cleaning the drain to make sure water didn't spill on any electronics. Second visit (1/29/15): The technician installed the new burners and the new flame sensor. The labor seemed a bit excessive since he had to make two trips.
Description of Work: The technician cleaned out the water drain for the exhaust blower, replaced the flame sensor, and replaced the burners.

They planned a new system for me that meets my needs exactly. Communications were prompt and helpful. The price was noticeably below the other bidder. The installation was done quite well. The installer put in a tough 12.5 hour day so I would have a functioning system when he left. I am completely satisfied!

The work took most of the day, but was done and operating well at the end of the day. The job site was left in good condition. The installer went through all the components and the operqation of the systems before he left. It is amazing how quiet the new system is and all the new options on how we can run the system.

The technicians called to let me know they were coming and asked if they could show up a few minutes early! They were both courteous, professional, and explained the maintenance steps they were going to take. When a problem was found, they showed me the bad part and/or issue, took me through the options, and let me decide which path to take to resolve or just note and watch for now ... no pressure. They worked efficiently and effectively together and completed their work on time as estimated. Overall, a pleasant maintenance service experience.

The technician performed a furnace checkup. We'd purchased a house that had been a rental property so wanted to make sure that the furnace was in good working order. The tech. checked for gas leaks, and tested to make sure the blower was working and that no parts were malfunctioning. He also gave me an idea of how old the furnace was and whether or not it was showing wear and tear. He was very thorough and polite. I sort of hovered nearby because I wanted to see what he was checking and why, and he was patient in answering my questions.
Description of Work: Tonna performed a furnace inspection and tune-up on the furnace in the home we'd recently purchased.

The Tonna team installed a new central air unit and furnace. The estimate was very detailed, and the job was completed exactly as described. I specifically waited several months to post this review to assure that everything worked well through the winter months. Everything has been excellent. The bid was received on 8/21/13, and the work was completed in one day, 8/22/13. I would not hesitate to refer Tonna Mechanical, they were extremely professional, thorough and easy to work with. Tonna Mechanical also installed a humidifier on my new furnace a couple months later and it has worked flawlessly.

Tonna was in transition and moving away from doing commercial work. Our project got caught in this transition which resulted in delays and some miscommunication. In the end, we were very happy with the work performed and the pricing, but it caused stress along the way.

We have been extremely happy with anything they’ve ever done for us. They’re always here when say they are going to be here. They clean up well after themselves. Our utility room is a very tight space and they did a really great job making the units work within that space and explained to us what would work best. They were very good about this. Another reason we went with Tonna Mechanical is we had called a different company who never came out; Tonna Mechanical came right out. We did have one issue after the installation due to an issue with the manufacturer, and they came out right away to take care of it. Their prices are in-line other companies. We would and have recommended their service to others.
Description of Work: They replaced our water softener, water heater, and our iron filter. The work took a day for one person to complete. We’ve used their services since 2008.
