Best Vrf/Vrv in Washington DC

In years of using plumbers both personally and professionally I've never encountered pricing policies as opaque as WL Gary's. They charged over $250 for the plumber to buy basic toilet repair parts. They charged for the plumber's time to generate an invoice even though it's automated. They charge for a full day's rental of a plumbing repair device that's stocked on the truck and was used for less than an hour. The basic quality of the real plumbing work appears to have been good, and the plumber was pleasant to deal with, but he did have to return to fix a problem with that expensive toilet repair. All in, I can't recall having felt so gouged by a company's pricing and will never darken their doorstep again.
