Best Hvac Maintenance in Washington DC

We had a great experience and would definitely recommend to anyone! We called around 8:30am and they were able to give us a same-day appointment, for which we were grateful. The technicians arrived by 12pm and had our AC working within 15-20 minutes. It couldn't have gone any better!

These guys really know their stuff! After struggling for months with hot water and heating problems which other technicians told me they didn't know how to fix or couldn't be fixed, Frederick solved both problems in no time at all. Can't recommend this business enough, and already planning on using them for other work!

Wore KN-95s; fixed the problem quickly.

Jose from Sila came over the other day for a seasonal maintenance service and he was great. He was on time (rare with service companies); answered all of my questions, and was very thorough in his checkup of my HVAC unit. They also have a great deal where they offer two maintenance appointments for $149, which is a good deal. Will definitely be using them again!

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!

They the job professionally and quickly. Will definitely call on them again.

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.

Fantastic experience. Best price and service was outstanding. Would recommend highly.
