Hottest day of the year, Air went out. Mike came to the rescue and got us fixed. Would highly recommend Tri State and Mike Molden

Mike was SO helpful. Our AC unit went completely out when it had just gotten into the 90’s… I’m getting married in two weeks and of course panicked because of the price. we were quoted $4,000-$11,000 from various different companies. We would have needed to replace our unit and coils due to the new units not working with our old coils. Mike went out of his way to find us a new unit that was last years model that WOULD work with our current coils. Instead of paying $4,000… we were only out $2,600. We are so unbelievably grateful for him! 🙌🏼 I could not recommend them any more. Don’t waste your money if you don’t have to.

Mike was able to make a last-minute stop at my house to fix my AC when all other area companies said it would be at least 48 hours before they would be able to come. He was able to rapidly diagnose and repair the issue. I would highly recommend his services!!

Showed up on time, knew what he was doing and got my central air unit up and going in no time! Very reasonably priced. Definitely recommend!

Called him about a heating problem. He was able to tell me over the phone a couple of things to try. Problem was resolved quickly. Good guy!

What Tri-State Heating & Cooling is registered to do
The State classifies Tri-State Heating & Cooling as plumbing/heating & a/c contractors. That classification comes from the registration itself, not from us — it describes the work the business registered to perform, and it is not an assessment of skill or a limit on what they may quote for.
