Caller says his name is Jim. Wants to give me a deal on duct cleaning. I told him I had 9 floors, he replied no problem. I told him we were radiated heat, he said we still needed our ducts cleaned. I told him we have 70+ units, again no issue. Booked an appointment for next week. Gave him a shopping plaza address, told him to ask for Richard as he would let him in. Good luck finding th duct work there.
