Best A/C System Maintenance in Washington DC

Two properties and both AC units from 10 years ago are a go! Very professional at a reasonable price!

I contracted with Al's Twin Air to get a sewer line camera inspection and sewer pipe location service performed. From the office administration staff to the service personnel I was extremely satisfied with the company's professionalism, customer service and helpfulness. All of my interactions were positive and the staff graciously answered all of my questions and earned my business. The service personnel answered a number of specific technical questions I had so that I knew exactly what I could expect on the service date. In addition, on the service date the technicians gave me, in addition executing the service, a wealth of in-depth knowledge about residential plumbing, HVAC and water systems. In fact, much of the information they generously offered extended far beyond the specific nature of the service call. In all, the customer service experience was fantastic and the information the service personnel shared has made me a much more competent and well-informed homeowner. I was very satisfied with the service.

Frederick was great! He fixed a Navien tankless water heater issue that had flummoxed two other plumbers. Next, he fixed the HVAC wiring to our Nest thermostat which one other electrician and one Nest technician could not figure out. In short, in one afternoon he fixed issues that four other professionals could not. If you have a Navien issue, call Charles & Sons first. If you want a problem solver ask for Frederick.

Excellent job - I couldn't be happier with the work and the price. If I do need a plumber again I would use them again. I would also refer them to anyone that needs a plumber.

The service was prompt and easily fixed. I appreciated the work and instructions on how to maintain our need so not to happen again. #2036 (Lal) was very professional and would request him again in the future.

Had the pleasure of working with them and definitely recommend. They were down to earth and followed through on their promise, which is very important to us as well.

HORRIBLE COMPANY

Henry Leon and the Lion Plumbing company are amazing! Henry came in, found out what the problem was and fixed all in an 1 hour! Thank youuu so much.

This business has been a life saver for me and relatives to whom I have referred A H Jordan. They are reasonable, always professional and competent. Never have I had to re-hire another to complete or finish a job where I have called Jordan.

Moved into a new place and found that the toilet kept clogging every single time! Called Plumbline Plumbers and they were able to come out in no time. Super friendly and quick work.

Extremely fast plumbing — fixed toilet, shower drain, and sink water pressure in about half an hour. Had Dave as a technician. Quick and professional
