I ultimately ended up fixing the issue myself (C line ended up not being properly connected in furnace lol) but when I was looking for pros, James reached out and gave me some really helpful advice over the phone and troubleshooted with me. He was upfront about call out and hourly costs and extremely professional. When I’m in need of a HVAC specialist in the future for servicing, or need to refer someone for help, James and Old Line Heating and Air will absolutely be my go to. Thanks again for being an honest professional.

Kevin and Andrew repaired our kitchen sink piping and installed a disposal. They identified the sink leak, was a leaky strainer which the previous plumber, kitchen renovation 5 years ago, had band aided the strainer with a loose collar by packing plumber's putty to hold together. They installed the correct collar and the disposal and their fee for the both of them was very reasonable. Previous estimate I received was twice as much. They were both personable and knowledgeable.

Details: Yes, repair is urgent • No, the building is not currently flooded • Leaking pipes • Other pipe issue • Sink • House
