The reviews speak for themselves — here's what your Front Range neighbors say about working with Colorado Bear.
"Nate was awesome, professional, and courteous. He explained exactly what he did and why he did it and answered every question that I had. A few hours after he had left he followed up with a phone call to ensure that everything was working properly. This level of professionalism is a rare find and I would happily recommend him to anyone needing their systems worked on. Thank you for everything!"

Why a Factory-Authorized Daikin Dealer?
As a Factory-Authorized Daikin Dealer we install and service Daikin's full lineup — heat pumps, furnaces, ductless mini-splits, and the Daikin One+ smart thermostat — and we register every install for Daikin's industry-leading 12-year parts warranty. That warranty isn't available through non-authorized installers.
Do you finance new HVAC systems?
Yes. We offer flexible financing through Synchrony, including special promotional terms on qualifying purchases. The application takes minutes, won't impact your credit to browse options, and puts a premium, energy-efficient system within reach. Apply on the financing page or ask your technician at the estimate.
What HVAC rebates can I get in Colorado in 2026?
Two main programs are active in 2026: Xcel Energy rebates for qualifying heat pumps and high-efficiency systems (up to several thousand dollars depending on equipment), and the Colorado state $1,000 point-of-sale heat-pump tax credit. Federal 25C/25D credits expired 12/31/2025. We handle the paperwork and apply qualifying credits at the invoice.
Do you offer a free second opinion on HVAC quotes?
Yes. If you have a quote from another contractor on a replacement install, we'll review the load calc, equipment match, warranty terms, and rebate stack — no pressure, no obligation. It's a credibility play: most Castle Rock buyers shop two or three quotes on $8k–$25k decisions, and we want to be the trusted technical second opinion.
Are you NATE-certified and licensed in Colorado?
Yes — every technician is NATE-certified and EPA-certified for refrigerant handling, and Colorado Bear is licensed and insured. License and insurance verification is available on request.
