100% Service, Inc.

100% Service, Inc. has served the Denver community for decades as a family-owned HVAC contractor, built on a foundation started by the brothers' father and now operated by Anthony and Frankie. With 215 five-star reviews, the company maintains an unblemished reputation among homeowners throughout the Denver metro area. Yvonne Litle's experience captures their commitment: after her urgent call about a water heater, the team had a new unit installed by 11:00 a.m., delivering every commitment made. Emily in the front office coordinates service calls, ensuring technicians reach customers the same day for urgent repairs, as Patricia Spindler experienced when her furnace failed in the afternoon.

What distinguishes 100% Service is their willingness to stand behind problems they did not originally install. Sean Marshall, a new homeowner, encountered an issue with a boiler system installed before his purchase. The team arrived, diagnosed the problem, and resolved it as if it were their own work, refusing to pass off responsibility. This approach extends to their installations of heat pumps, water heaters, and boiler systems, where technicians maintain clean worksites and complete projects efficiently. The brothers' father established standards emphasizing transparent pricing, and several reviewers note reasonable fees compared to other contractors.

Jake and Isaiah earned specific praise from a reviewer who called them amazing, describing the pair as courteous, respectful, knowledgeable, professional, thorough, and funny. Anthony appears across multiple reviews, coordinating with Emily and Diego to guide homeowners through every step. Yvonne Litle's review highlights the team's speed and communication: her same-day water heater installation was completed by 11:00 a.m. after a speedy reply to her call, with every commitment honored. The consistent naming of specific technicians across 215 reviews reflects a stable team that Denver homeowners return to decade after decade.
