See Why Our Customers Love Us
Old Line has been to our house a few times, most recently they discovered we had duct issues. The repair was faster than they originally thought and now not even 24hrs later it is feeling much better in our home. Can’t say enough good things.
My wife contacted them. They came out very professional and we decided on a new unit. Price was very fair. We already had estimates. One week later unit was installed and now very comfortable. Excellent communication, professional and fair prices.
Old Line came for a leak in my water heater. Not only was the fix cleanly done, but he explained what he was doing every step of the way. Really appreciated the honest service and pricing – would strongly recommend!
