Anthony went above and beyond in routine maintenance, identifying related issues with our fireplace glass which had melted insulation. He put up a sign to not use the fireplace, which was a big help. Thank you!

Arrived on time and extremely polite. I have the service contract and it’s good knowing that my furnace is in good working order for winter.

Matt is always prompt and friendly and does a great job! My only complaint is when I call the office, they are rude and disorganized.

ANthony was very pleasant, helpful, and thorough. I feel confident the work was done well. In addition to performing maintenance on my HVAC system, he installed a smart thermostat and answered the questions I had about its use.

I've used Northern Air (previously Northern Colorado Air) for many years, and have always been happy with their service. The techs always arrive on time, and are very thorough in their inspection, giving me information on how my equipment is performing. They have kept my system running all season, every year. The most recent tech, Ethan Peck, was excellent.

Ken, came out because we suspected I had a coolant leak which was causing the A/C not to function properly. Ken found the leak in about 10 minutes added coolant (my words) and tested the system to ensure it was working properly. Highly recommend Ken as the service tech to work on your HVAC. With employees like Ken I recommend Northern Air- great customer service service!
