Best Extensive Plumbing in Washington DC

DO NOT HIRE THIS COMPANY. A technician visited to service an HVAC unit that was not working but left part way through the visit, mentioning that they didn't have a part and were going to go get it to finish the job. The never returned. Not only did they not return, but they didn't call to update us with what was going on either. We were just left waiting and wondering with no heat in below freezing temperatures. I called the number listed for the company for more information -- as it turns out, the technician simply didn't know how to fix the problem. It had nothing to do with a missing equipment part. Lied to and left hanging.
