Claim This BusinessAbout Fusion Heating & Cooling
Founded in 2012, Fusion Heating & Cooling is a family-owned HVAC contractor headquartered at 13845 W 85th Dr in Arvada, Colorado. Founder Roger Arellano built the company from the ground up, and today his team holds NATE certifications and maintains full licensure while serving Arvada, Westminster, and Wheat Ridge. The company earns a 4.8-star average from 48 homeowner reviews and operates every day of the year, a critical detail for a Front Range community where sub-zero winter nights and peak-summer heat waves arrive without warning. Licensed, bonded, and insured, Fusion has spent more than a decade earning trust in the Denver metro area.
What separates Fusion from neighboring contractors is the combination of NATE-certified training and around-the-clock availability. While many HVAC companies close on Friday afternoons, Fusion fields calls 24 hours a day, 7 days a week. Same-day and emergency service is listed on the website, and the technicians hold industry-recognized credentials that the average homeowner can verify independently. The service catalog covers air duct cleaning, air handlers, heat pumps, thermostats, new AC installations, furnace and heating repair, and indoor air quality solutions.
Reviewer Frank Zavala called out technician Troy by name after a weekend furnace failure. Troy arrived within 30 minutes, walked Zavala through his options, and placed space heaters in every room while the system was being repaired over five days. Zavala noted that Fusion helped a household on a fixed income without pressure. Samantha McCann described a pre-holiday furnace failure and a technician who fit her into a tight schedule, sourced parts for an aging system, and returned the same day when a secondary issue surfaced. Jerome Weeks credited Troy with a last-minute Friday afternoon appointment and a fast diagnosis of a clogged condensation line followed by a same-day repair. Across all three stories, a single technician answered urgent calls with clear explanations and thorough work.
What Customers Say
Across 48 homeowner assessments, emergency response and technician skill drive the strongest praise. Troy earns direct mentions in every 5-star review, with reviewers consistently noting arrival within 30 minutes, detailed repair explanations, and same-day solutions for urgent furnace and AC failures. Negative feedback touches on pricing, while positive reviews highlight diagnostic accuracy and genuine care rather than upsell pressure.
