What our clients are saying

R. Larson

Extremely happy with my decision to use DNI. Installed cash price of my new furnace & AC unit was about 23% lower than the competition. Chris was very knowledgeable, conscientious, and top notch! The whole crew was excellent!

R. Barcklow

DNI and Chris specifically were amazing. My furnace went out with the first Colorado storm and they were able to come out the next day and provided me with honest, transparent service so I could make the best decision for my budget. There was never any pressure from Chris between buying a new furnace and fixing my old one. I felt like they were patient and willing to work with me and my needs. I would highly recommend DNI for heating services.

J. Jacobs

The service personnel were top-notch – friendly, professional, and dealt with some unexpected issues without missing a beat! Plus, they were dog lovers and made friends with my best buddy Highly recommended!

K. Kitten

Trustworthy, fair and will advocate for their clients. Whether it is maintenance or replacement DNI is wonderful. As a small business, the options are limited and expensive for replacing a unit that is original to the building. Chris L. worked exceptionally hard to ensure that our needs were met, ultimately finding the most cost effective solution.

M. Southworth

DNI Heating got out to my house, assessed the problem and installed a new furnace for us within hours on a Friday afternoon. We did not have to worry about the 0 degree temperatures coming in that weekend. The service was great from the minute I called to helping us register our furnace.

D. Johnson

This crew has saved me on multiple occasions. From heating to ac service they have done it all for me. Always great customer service and a quick response time! Thanks for the continued great service DNI!
