Thermal Air replaced my A/C and furnace. They did excellent work making sure everything looked good and were up to code. They replaced all the bad wiring. They were very professional ensuring everything was done and cleaned up before leaving. I would recommend them for any of your heating and air-conditioning needs.

After many years in our house my wife recently suggested we test for radon. We purchased a charcoal test and sent it in for analysis. The result was 29. EPA recommends remediation if above 4. I borrowed a digital tester from our local library and it confirmed high levels in the basement. I searched websites of local companies that do radon mediation and saw Thermal Air specifically dealt with it. I also found them listed on the ND State Health department site and had a good recommendation from a local City official. I called Thermal Air and Terra returned my call promptly. She scheduled an appointment for Darrel, the owner, to come out and review the situation. He came out after business hours because he was attending classes on a certification. He arrived with a technician and spent an hour reviewing and discussing options. We have 2 sump pits and I thought we may need to pipe them both. Darren said we should cap both pits but only pipe one. Plan B would be to add a 2nd fan if needed. He submitted a price within 2 days and we it was reasonable and fair. We worked with Terra on getting the proposal signed. They scheduled us for the following week. The technician, Nick, was on time, efficient and personable. He kept us posted as to his progress and had the work done in 5 or 6 hours. He said he had completed quite a few of these systems. Nick was easy to get along with and projected a trustworthy personality. Terra said they will return after two weeks to test the air using their high end tester which is currently underway. This test takes 48 hours. I kept the library tester for my own curiosity. The readings have been all under 0.50. The system is definitely working. We highly recommend Thermal Aire for radon systems.

Absolutely delighted with the service provided by Thermal Air! They recently installed a new heating system in my home, and I couldn’t be happier. The team was not only friendly and efficient but also took the time to educate me thoroughly about my new heater. They ensured I understood how to operate it effectively and shared tips on maintaining its efficiency. It’s rare to find such dedicated customer service these days. Highly recommend Thermal Air for anyone looking to upgrade their heating system with a reliable and professional service. Five stars all the way!

We had them install a new furnace in our house. Thermal Air is by far the best place to go in the Grand Frorks area. The Professional well trained staff get it done right, and the service is top notch.
