Reviews of local pros in Boulder, Colorado

Service was great, quickly found the problem and fixed it, very professional and went above and beyond!! Thanks!!

Thank you D.N.I. Dean did good work and in a timely fashion

Dean was great to work with again what an amazing company

Dean and all the folks at dni did an absolutely fantastic job on my new system

Had an issue with the heating system constantly calling for heat and running up my propane bill. D.N.I. located and resolved the issue in a timely, professional manner.

Mr. Dean Fornsworth is very dependable. Always able to answer my questions about my system. Always on time.

The responded very quickly and was at my house early. It was a quick fix and they were very professional. Will use them for all my AC / heating needs.

Thanks Dominic for coming out and fixing our water heater. You were very professional and quick! Everything is working great!!

Derick White was great!!!

They came out to move my AC unit temporarily for some yard work we were having done and went above and beyond what I asked for. They were upfront about cost and we had a great experience with both the scheduling and technicians. Would use this company again for anything AC related.

Realized I needed an emergency unscheduled visit for a quick service on a Friday. DNI had someone to my house before end of day! DNI is always responsive to their customers. Awesome service!

D.N.I. Heating-Cooling-Refrigeration-Plumbing appears to be a reputable company with a strong reputation for providing quality services to its customers. While there may be some room for improvement in terms of communication and pricing transparency, the majority of customers seem to be satisfied with their experiences with the company.

Jordan and his associate were sure to give clear explanations of what they needed to do to fix the problems and gave me options and ideas how to prevent these kind of plumbing & heating issues from happening in the future. Great job guys and thanks DNI.

Jessie Swanson of DNI did a great job replacing toilet and all the worn out shut off valves in my 20 year old home recently purchased. Worked hard, answered all my naive questions too! Thank u DNI for your responsiveness and professionalism!

I rarely leave reviews.
I do not know, how everyone else had 5 star left reviews. Two technician came on 8/8/2023. They came in my store 1:29PM and They found out what was problem 2:08pm(tooks 39min). They go back to my parking lot 2:10pm and they left 3:03pm. When they check my cooler, They did not know what was the problem first. They called someone to check the problems. The other technician is not technician. He was helper(he did not know anything). Than DNI charge me $772.50. They only found problems. I didn't even fix it.
Does this make sense?(39 minutes of work). Avoid this company if you can

Damn Dean was the best technician I’ve ever seen in my life. That man is amazing.

I've been using DNI for years now to do annual equipment inspections. The Techs are experienced, professional, on- time, and communicate well, hence my 5-star rating.

However, like most places, the cost of their 30-minute inspection just continues to climb. A few years ago, is was around $300/year for both inspections. My next check up will cost $230, so $460/year for both A/C and furnace. Aside from piece of mind, on an older, out-of-warranty HVAC system like mine, their inspection gives you a 10% discount on any needed repairs. So, I won't break even unless I have a repair that costs over $4600, which is something MAJOR (or more the longer it is and more services are done before a repair is needed). They have unfortunately priced themselves out of my market, so I will continue cleaning my own furnace, replacing my own filters, cleaning my own A/C compressor fins, and servicing my own steam humidifier, and forgo the biannual service checks.

Brayden Goodrich did a fantastic job servicing us! We always appreciate the work he does for us at Freddy’s and look forward to working with him in the future!

Jordan, Rob and Armando were speedy, professional and such a pleasure to work with. My outdoor plumbing issue was remedied in less than a day. Highly recommend!

Cole and Justin were very helpful and knowledgeable. Quick and efficient work and gave an excellent rundown once they were finished.

WOW! HVAC is so cool! Such a great team that helped! Damian was by far the best!
