Best Heating System Maintenance in Washington DC

mr super plumber renovated our bath room and did a great job at a great price , they were extremly proffesional. I strongly recommend this company. We very happy with our new bathroom. Thank you mr super plumber!!!!!! shaqita breeden silver spring md

Sorry but I was very disappointed with the service and price.

My main complaint is that they didn’t fix the problem and didn’t even do what they said they were going to do to try to fix it.

Beyond that, the price was absurd. They charged $120 for materials for maybe $5 worth of duct sealant (and didn’t even use enough to seal the ducts!)

They charged 12 hours of labor at $90 an hour, but the guys were here for about 2.5 hours, and most of that time was spent waiting for another guy to bring over duct sealant. I called and pointed this out and they reduced it to 6 hours of labor.

They were on-time, very nice, easy to make an appointment. I just don’t know what I got for $800.

I had a VERY good experience with this company for a water heater replacement. Frederick was fantastic. Professional, polite, funny, and clearly good at his job. Price was good, service was great and fast. Strong recommendation.

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

Sila repaired one of my HVAC systems after another firm insisted I should replace it. They’ve provided seasonal inspections on both my systems and are thorough and knowledgeable. Highly recommend.

Very fast professional and friendly service

This is my go-to for plumbing and heating in DC. The workers are very familiar with old houses and related issues. Reasonable prices and fast service!

We had a great experience with Plumbline. Their knowledge and experience helped us save a ton of money and get our problem solved quickly. We were in a pinch and they showed up quickly at night. Great choice if you’re looking for a veteran plumber who doesn’t mince words and is honest about the trade.

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.

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.

Highly recommend. When my HVAC died I called three companies for estimates. The first (Gary Frank Heating and Cooling) never showed for their appointment. The second (John C. Flood) showed on time but asked an obscene $11.6k for a new HVAC unit. The third (Jimmy Gusky) showed on time and quoted me $4k less than John C. Flood for a comparable unit. So if you’re looking for an honest business to replace your HVAC or heat pump, this is it.
