Built one job at a time.
Capitol Climate Systems started with a single van and a handful of rowhouse customers. Today we service over 2,000 DC homes and a growing roster of multifamily buildings — and we still answer the phone ourselves.
A boring story we're proud of.
We're a DC-based HVAC company that grew up working on the District's trickiest housing stock — narrow rowhomes, finicky converted condos, prewar apartment buildings with mechanical rooms that haven't been updated since Carter was president.
Along the way we earned the trust of property managers and developers who needed someone to handle entire buildings, not just one-off service calls. That's how the commercial side of the business was born — and why our portfolio now spans nine buildings across the District.
We show up on time, we tell you what it'll cost before we start, and we stand behind our work with a five-year workmanship warranty. That's it. That's the whole pitch.
