However this is second time we have had this technician + each time he has not sealed the furnace appropriately after cleaning. Last time the tape came off as soon as furnace came on. Another technician had to come + seal it properly. We usually have one of 2 other technicians come since that incident. I understand this appt. was set up quickly. Once again it was not sealed properly or neatly. There was a gap. My husband has put on some additional tape."
