Commercial Services


Optimizing the comfort, health, safety and energy efficiency of the commercial space is good for business. Taking good care of your workers, customers, essential systems and property elevates the quality of your brand, proves your commitment to best practices, complies with codes and reduces expenses. For commercial services taken to the next level of benefits, reach out to the experts from DNI Heating, Cooling, Refrigeration, & Plumbing, Inc..

At DNI Heating, Cooling, Refrigeration, & Plumbing, Inc., we are committed to increasing energy efficiency while minimizing risks for our commercial customers. Ask us about the installation, replacement and essential cleaning of kitchen exhaust systems. By regularly degreasing your system, our professionals eliminate extremely flammable residues, promote superior airflow, improve equipment performance, decrease the potential of contaminated breathing air and protect system reliability and longevity.

DNI Heating, Cooling, Refrigeration, & Plumbing, Inc. highly encourages the advantages of a make-up air system. This innovative HVAC solution pulls fresh air from outside to replace air in the building that has been removed via exhaust fans. Due to tighter thermal envelopes, make-up systems are an essential addition to avoid depressurization.

While this alternative supplies fresh air the same as a standard ventilation fan, the make-up air system regulates the temperature to improve comfort and energy efficiency.
Putting over 25 years of in-field experience to work for our customers, DNI Heating, Cooling, Refrigeration, & Plumbing, Inc. further specializes in commercial chillers. Requiring less energy than more conventional air conditioners, chillers use water rather than refrigerant, significantly trim costs, provide powerful cooling output and handle the demands of larger buildings with ease.

Contact DNI Heating, Cooling, Refrigeration, & Plumbing, Inc. for more information and scheduling across Longmont, Boulder, and Loveland Colorado. We cover all commercial services from new installation, replacements and maintenance to 24/7 emergency repairs.

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!
