This organization has been calling twice a day for the past three weeks. I finally answered the phone today. They tried to sell me duct cleaning and a furnace tune-up for $59. They tried to schedule me for next week. I let them keep talking then told them I owned and HVAC company and didn't need them. They apologized and thanked me. Received another call less than 1 hour later. When I answered the call it was a dead line. They never mentioned their name.
In Pasadena, MD, get calls weekly from these jerks. There will be a special place in Hades for these people. Everybody's gotta make a buck but seriously I've had it.
