What Our Clients Say?
Jeff Kroll2025-09-26 Great service and good knowledge of systems. D E2025-09-13 Nixon was great! When I was unable to resolve my hot water heater pilot issue myself, I feared the repairs would be costly. Not only did Nixon repair the problem within an hour, but did so within their standard service call fee. nicholas smith2025-09-09 Nixon is a true professional, he got straight to the point and explained everything in detail. Everything on the invoice was absolutely perfect and will be using/recommending them to anybody that needs good hvac work.Thanks Guys!!! Elaine A2025-08-22 Nixon was super helpful and did excellent work for a reasonable price. The previous owner of the house needed the furnace fixed and only did the bare minimum so Nixon was honest about how it might give us problems during the winter so we went ahead and got a whole new setup. Very happy with the service provided and highly recommend Fireside! Ravi Patel2025-07-24 It’s good Todd Wiseman2025-07-23 Don't think there is a better HVAC company in the Denver area right now. Great work at a reasonable price and very timely and responsive. Installed a new AC unit. Highly recommended. Update: had them back for a furnace replacement in another house with a 40+ year old unit that was end of life about a year later. Same great experience. Update: 3rd AC / furnace unit in a year. Had it up and going super quick. Could not be more happy. Pics to show the quality of work done. Update: Just did a new furnace to replace a very old one in a condo, and also a cleaning service for an existing 2012 Amana AC Unit. Nixon replaced some insulation that went bad to make it work more efficiently Service went well as always - very prompt - and communication was excellent. His customer service system always works great too in letting me know when jobs are started and done without even asking. Recommended.... Paul Zwiebel2025-07-23 Responsive, diligent, professional. Communicates well. Steven Betts2025-07-23 Fireside was prompt, courteous, and professional. Didn’t try to oversell and quickly fixed my problem. Highly recommend them! David Moore2025-07-09 Fireside put in a new hvac and furnace for me. The cost was well under competitors for the same brands, and the service was excellent. You can pay a premium to work with a big company just looking to put you through their revenue engine if you want, but with Fireside you get people obsessed with their trade, rapidly responsive and willing to go the extra mile for quality and service. Highly recommended. Jody Kuhns2025-07-02 Nixon was amazing. He answered every call and got me accurate information quickly. He did not try to upsell me something I did not need. He did a spectacular job for a reasonable price. Super honest, professional and dependable!Load more
