Best Hvac Maintenance in Washington DC

They submitted a bid on a commercial project then ended up not returning calls or emails, either from the estimator directly or from the office. Set us back quite a bit.

I had a water heater replacement right before Christmas. I called 3 HVAC companies. Mr. Charles' quote, advice and professionalism won my business. The great job he and his assistant did with the replacement and other follow-up work kept my business. I'll be calling him with any future plumbing and HVAC needs.

Had a clogged main sewage line. They came within 30 minutes and resolved the problem in 1 hour. Great service!

Exceptional professional service per their norm over several years.

Great, quick, and efficient service! I had one of their plumbers come fix what I thought was a shower valve issue since I wasn't receiving hot water on it (which i googled), their experts let me know that they needed to install a spool & cartilage to my shower to fix it. Of course they knew the issue and resolved it there asap!

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.

WL Gary proudly says they've been in service for 120 years but they still never learned how to work with customers.

My advice to you before you work with this company is to ask for a free estimate. This way you can get a quote on how much it will cost and their recommendation so that you can compare it with other companies. If they don't provide a free estimate, other companies will. Take your hard earn money else where.

I made a mistake of having them come without asking for a free estimate. They failed to let me know that the visit will cost money, they failed to tell me that there will be a service charge, and they failed to tell me what their rate is. I ended up having to pay for their visit despite: (1) never telling me what their rates and service charges are or that there will be one and (2) giving me the wrong diagnosis and wrong recommendation.

I was having water leaks because of condensation. WL Gary recommended I replace the whole HVAC unit and hungrily wanted to charge me $4,000+ and that this was the only way. I had another company come give me a free estimate and this other company said I just needed to replace the insulation around my pipes for $300+ and adjust my water pan. I decided to go with the other company and have the insulation replaced. After replacing my insulation and adjusting my water pan, it fixed my leak 100%.

After their poor customer service which was a huge red flag for me and lack of interest in giving back money they charged me for doing nothing other than give me a wrong recommendation, I am really glad I did not trust WL Gary.

Beware of this company and make sure you get a free estimate from different companies.

Decline! But this company needs to consider a live rep to answer their phones!
