We had Shay convert our furnace from oil to propane. He did such an amazing job. You would think there would be a big mess but he is so neat and the install was perfect. The ducts were cleaned after he left and THEY even mentioned how amazing his install was. We also got him to install an AC unit and it is top notch. He walked us through the new nest programming. You should call him if you need any A/C or heating needs.
