HVAC reviews in Hillsboro, North Dakota

Great service from start to finish. They were friendly, showed up on time and didn't waste a lot of time. I highly recommend them.

Dennis was very reliable and went above and beyond. Came back and checked in to make sure everything was working at no extra cost. Highly recommend!

These guys are the real deal. Showed up on time, fixed the problem fast, and didn’t try to upsell me on stuff I didn’t need. Honest, professional, and solid work all around. My system’s running better than ever. Can’t recommend them enough.

Dennis came out immediately and resolved our heating issues. He shows up when he says he will be there and was reasonable as far as cost goes. Will certainly use him again in the future.

Dennis has been amazing! He showed up when he said he was going to, and he came back to check on everything to make sure it was working. The best part about working with Dennis is his quote was exactly what his invoice was, which isn't very common these days!

Dennis was great to work with in replacing our furnace and AC. He was quick with his price quotes and even during the estimate provided a carbon monoxide detector for us to use until the new furnace was installed. He showed up when he said he was going to and his pricing was very fair. Will definitely use him again in the future!

I cannot recommend this HVAC company enough! From start to finish, the service was absolutely top-notch. They were professional, honest, and incredibly knowledgeable. It’s so hard to find a company these days that truly cares about doing the job right — but they absolutely do.

They showed up on time, explained everything clearly, and made sure we understood our options before moving forward. No pressure, no upselling — just genuine, hardworking service. The quality of the work speaks for itself. Our system is running better than ever!

If you’re looking for reliable, trustworthy HVAC professionals who treat you like family and take pride in their work, this is the company to call. You won’t be disappointed!

I can’t say enough good things about EnviroTech! They came in and installed a brand-new heating system and full duct setup in my home, and the entire process was smooth, professional, and done right the first time.

The technician was absolutely wonderful — kind, warm, and personable — and took the time to explain everything to me in a way that made sense. You could tell he genuinely cared about doing quality work and making sure I felt comfortable with the whole process. That level of trustworthiness and attention to detail is hard to find these days!

Everything looks clean and works perfectly, and I can already feel the difference in how evenly my home heats up. It’s so nice to see a small, local company that takes such pride in their craft and treats customers like neighbors instead of just another job.

If you’re looking for an HVAC company you can truly trust, I highly recommend EnviroTech. Honest, reliable, and an absolute pleasure to work with — five stars all the way!
