Champion HVAC Service

Champion HVAC Service has served Denver homeowners since 2014, when Derrick Arellano founded the family-owned business at 1630 Chestnut Pl in the LoDo neighborhood. With 41 verified reviews earning a 4.8-star average, the company fields NATE-certified technicians available around the clock, every day of the year, including holidays. The company holds Colorado state licensing and maintains full bonding and insurance coverage, serving the Denver metro area with particular depth in downtown, Capitol Hill, and the Highland neighborhoods.

What distinguishes Champion HVAC from larger competitors is their commitment to transparent, pressure-free consultations. Technicians arrive in marked vehicles, diagnose problems on-site, and present options without upselling. The company advertises same-day service availability and maintains a 24-hour emergency line for midnight breakdowns during Denver's brutal summer heat waves or winter cold snaps. Their service menu spans the full residential spectrum, from air duct cleaning and indoor air quality remediation to heat pump installations, thermostat programming, and complete furnace replacements.

Customer stories from verified reviews illuminate the company's operational philosophy. When Brad Benitez's furnace failed on a Saturday during a Denver cold snap, technician Jayden responded immediately, worked late into the night to ensure the family's safety, and installed a replacement furnace the very next day. Jaime Garcia's review describes a multi-visit consultation process where technician Maddox spent extra time explaining furnace options for a challenging installation space, then coordinated a two-person crew who fabricated a custom duct piece on-site at no additional charge.
