Claim This BusinessDC Air Conditioning & Heating operates as a locally owned HVAC and plumbing contractor serving Washington DC residents from its 14th Street NW headquarters in the Adams Morgan neighborhood. With 397 customer reviews yielding an exceptional 4.9-star rating, the company fields a team of licensed technicians available around the clock, every day of the year. The business serves the full district including Dupont Circle, Glover Park, Woodley Park, and surrounding neighborhoods, responding to both residential and light commercial calls for heating, cooling, and plumbing repairs.
What distinguishes this contractor is its commitment to transparent pricing and customer education. Multiple reviewers specifically note that technicians explained repair options and costs before beginning work, with no pressure to purchase unnecessary services. The company advertises flexible financing options through HAVC, making larger system installations more accessible. Their website references refrigeration services alongside standard HVAC offerings, suggesting broader capability than typical residential-only contractors. Technicians routinely walk customers through system operation and maintenance, turning single visits into ongoing relationship opportunities.

Dario Caldara credits the same technician with arriving at 8 PM on the same day during a cold snap, completing the repair despite late hours. Alicia describes receiving price estimates via phone before any house call, allowing informed decision-making without surprise charges. Multiple reviewers praise Mohamed by name for same-day response, diagnostic clarity, and respectful treatment of customers and their property.
