Greg Our tech was great and knew what to look for after I explained the issue we were having. He explained everything he was going to do to check things out and to repair our generator. Everyone I spoke with at Tristate were great to work with and very helpful. I’m very pleased with the service. Thank you, Mark and Susan

Tri State Water and Air absolutely exceeded our expectations! Huge thanks to Derek Ham for providing immediate, clear answers to every question we had and for jumping right into action to get everything scheduled. From the moment I made the first call to the final setup, the entire process was seamless and stress-free.
In less than 48 hours, we had a brand-new permanent generator fully installed and ready to go. The team was professional, efficient, and clearly knew exactly what they were doing. In a time when peace of mind really matters, they delivered in a big way.
If you’re even thinking about a generator, don’t hesitate—call...⭐⭐⭐⭐⭐

Greg did not fix the problem my Generac is still not working and have not worked since Nov 19, 2025. He told be it need a Rotor part on December 31. Will take 2 weeks to order the part. He just now coming out to try to fix it today March 3. Come to find out he did not bring the new part with him today. So he told me he got to order the same part he was supposed to have ordered ack in December. I am still sitting here with no generator going on 5 months. I am very disappointed after I paid 14,700 for this product and Tri State cannot fix it. Why I cannot get a new one I which someone tell me instead of selling me dreams. Someone needs to step...Greg did not fix the problem my Generac is still not working and have not worked since Nov 19, 2025. He told be it need a Rotor part on December 31.

Someone needs to step up and make a decision because this is not the way you treat a customer after I paid that kind of money!!! Please Help

Kevin May came out and performed a checkup service on my generator, and did an amazing job. After he was done he explained everything he did and all the work and checks that were performed. He was extremely professional, thorough, and knowledgeable about everything. I cant recommend him enough

Aaron did a fine job replacing our old system. The job was completed in less than 3 hours. Aaron did a great job in planning and had everything he needed. He was very polite and explained how the system worked as he worked and after completion. Thank you Aaron.
