Redline Heating and Cooling

Redline Heating and Cooling LLC has served Arvada and the northwest Denver area since 2004. The family-owned contractor holds a 4.8-star rating drawn from 218 reviews, with weekday service available 7:30 a.m. to 4:30 p.m. Monday through Friday. The shop operates from offices in Arvada, serving Westminster, Thornton, and surrounding communities with residential and light commercial projects spanning new installations, system replacements, and ongoing maintenance. A Carrier factory dealer, Redline offers access to manufacturer-backed parts and warranties on qualifying equipment.

Beyond standard split-system work, Redline handles ductless mini-split installations, whole-house zoning controls, and indoor air quality products including humidifiers and dehumidifiers. The Arvada shop draws on Carrier access for specialty replacement components, and maintains a commercial division that has supported a named construction company on ongoing development projects for over a decade. Reviewers specifically note the company correctly diagnosed a problem another contractor had misquoted, potentially saving a homeowner thousands in unnecessary charges.

Brandon appears by name across multiple five-star reviews, consistently described as patient, thorough, and communicative. For one reviewer, he arrived the same day to address heating system issues and spent time explaining every step of the repair process rather than wrapping up quickly. Another homeowner credited the team with identifying a $4,000 repair need that a previous contractor had misdiagnosed, calling the honesty and accuracy a standout experience. Ernie was named by a customer as the primary contact for an accurate diagnostic that avoided an unnecessary major expense.
