O&S Services

O&S Services is a Denver-based HVAC contractor operating under license number N/A with a perfect 5.0-star rating gathered from six verified customer reviews. Founded in N/A, the company serves residential clients throughout the Denver metro area, including neighborhoods like Park Hill, Wash Park, and Capitol Hill. Homeowners who have worked with O&S Services describe the team as professional and trustworthy, with technicians who take time to explain system findings before recommending repairs.

What distinguishes O&S Services from other Denver contractors is their emphasis on transparency and accessibility. Multiple reviewers note the company provided same-day estimates when others were too busy to respond, and completed full furnace installations within the same week of initial contact. This responsiveness proves especially valuable for urgent situations like heating system failures in newly purchased properties where families need reliable warmth quickly.

Customer stories from recent reviews illustrate the hands-on approach that earns five-star ratings. When Roy Morales purchased a rental property with a failed furnace, O&S Services arrived the same day for an estimate and finished the installation within days despite other companies declining the job entirely. JATT 5.0 similarly praised the thorough post-inspection walkthrough of an entire HVAC system in a newly purchased home, noting the team reviewed the home inspection report before servicing.
