Castle Rock AC Repair From a Team You Can Trust
Castle Rock sits at a higher elevation than much of the metro, which means slightly cooler average temps — but that doesn’t make a broken AC any more tolerable on a 95-degree July afternoon. When your cooling system fails, Done Plumbing, Heating, Cooling & Electric is ready to respond same day, any day of the week.
Our technicians service all major central air brands as well as ductless mini-split systems. We diagnose the problem on the first visit — low refrigerant, a worn contactor, a failed blower motor, or a system that’s simply past its useful life — and explain your options honestly before recommending a path forward. We’ll repair when repair makes sense, and we’ll be straight with you when it doesn’t. Pricing is flat-rate and given upfront, with no hidden charges after the job is done.

Call NowAbout our work in Castle Rock
Local knowledge, local response
Done! Plumbing, Heating, Cooling & Electric has kept Castle Rock and Douglas County homes comfortable since 1999, with licensed plumbers, HVAC techs, and electricians on call across the South Metro. One call covers heating, cooling, plumbing, drains, electrical, and water quality — and our crews answer 24/7 when something fails after hours.
We work in neighborhoods like The Meadows, Founders Village, Plum Creek, and Crystal Valley and know the area around the Outlets at Castle Rock, the Rock at Rock Park, and Philip S. Miller Park. Local homes run to a historic downtown surrounded by newer master-planned subdivisions, so we size repairs and replacements to what Castle Rock actually has.
Castle Rock sees hot, dry summers and cold, snowy winters that push heating and cooling systems hard, which is hard on furnaces, AC systems, and water heaters. We tune, repair, and replace them before a Colorado cold snap or a July heat wave turns a small problem into an emergency.
