You would feel that when you live in an house building, most people would have the same heating or cooling system. I can tell you that isn’t the case, however my house doesn’t get nearly as much cooling system as the house next to me. I was jealous of their cooling system. I used every reason I could feel of to visit my neighbors, because I had cool air for a few minutes. My house wasn’t hot, however it was warmer than someplace else I had been in the building. I called the repair person and told him about the cooling system, but he said he didn’t have any complaints from anyone else, so he thought maybe it was just me. I wanted him to come look at the air vents and see if there was anything wrong. He wasn’t thrilled to be called, although I needed more cooling system. When he got to my apartment, he looked at the thermostat, however it was working well. He then checked the air vents. He said they were entirely dirty and was going to vacuum them out. Half an hour later, he was back with an industrial vacuum cleaner. The more he sucked out, the more he was finding in the air vent. He asked if I was having a beach party here. He didn’t know the air ducts were that dirty. He said I would need to take what I had because he had to call the Heating and A/C company and get the air duct cleaned before I had more cooling system. I would thrilledly wait if it was going to be cooler in my apartment.
