Best Air Conditioner Service And Installation in Washington DC

They were professional, honest and great. Happy i proceeded with them as opposed to the first 2 contractor referrals that my home warranty company tried to send. They were honest and good

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.

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

Pricing is reasonable and billing is very clear. They are the most work focused and responsive company I've worked with in a long time. I represent multiple residential clients and they have been incredibly responsive and thorough without fail. Highly recommend.

Those guys are real professionals and they do their job perfectly. Evertime I call them they get to my place right away and fix all my plumbing, heating, and cooling issues.
