Kathy M. “Thank you for all your help when part of the furnace filter fell down into the furnace. Your instructions and patience (especially waiting while I looked for tools) on how to do this were terrific. I didn’t know you had even called back before you left work, to check that all was okay, as I wasn’t home until later that evening-because I had to leave the house again as soon as the furnace was working. Thank you very much!”
