Best Commercial Hvac in Washington DC

I have used Al's Twin Air for several years for all my HVAC needs, for my primary residence and rental property. The staff are always professional. They arrive on time, complete the job as promised. The lady in the office is excellent. When I called requesting emergency service when my air conditioner died during the extreme heat, she worked her magic (lol) to get someone to my home very quickly. I have recommended Al to all my friends. They have had the same professional experience.

I got my HVAC system repaired by them and they were very thoughtful and open with questions. I can't say the same with other companies who tried to overcharge.

I had a serious and widespread plumbing issue in my condo caused in part by the faulty installation of pipes years ago. Elie and his team correctly diagnosed the situation using a hi-tech camera (which produced a video of the interior of the pipes so I could see exactly what the problem was) and set to work replacing and correctly reinstalling a large part of the plumbing tree in my ceiling. What a relief! Elie and company know what they are doing and accomplish the work for a fair price.

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.

Had them do a new AC and Heating unit install in August which went great. About 3 months later had an issue with our ventilation system which they did not install (carbon monoxide) and they came out three times in same day I called to clear it up (at no charge). Great service and responsiveness. Would highly recommend!
