Amazing service. Fixed my dryer vent and installed the new dryer in just about 30 minutes. It was done expertly, and kept the drywall perfect. Very exceptional job.

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.

I hired them to diagnose a problem with my electric HVAC unit. They replaced a sensor and charged me $706, but the issue remained completely unresolved. I eventually brought in a different HVAC company, whose technician identified a completely different issue and fixed it properly. When I informed the original company, the owner messaged me saying they would reimburse me, but that never happened.

Team was responsive, knowledgeable, and addressed our plumbing concerns with the kitchen sinks.

My office AC was not working correctly and they came out the same day. They were able to get my AC pumping out cold air within the hour they arrived. Fast response and great service! šŸ‘

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.

Great experience, quick service

My new water heater was installed today and I couldn't be more pleased. Owner James came out to assess the project and give me my options in a timely manner. When I chose to get a new system, he worked with me on price and installation time. He sent 2 men to install, Mark and Dillon. They were respectful, professional and polite, did a great job, left the area clean and took the old system away. I couldn't be hapoier. I highly recommend them!!
