I recently had a new air condition unit installed in my house. It does not appear to be working properly although the company that installed it says it is. Below are the problems I am having and the specs on the house/AC. Any comments would be appriciated.
House is 2600 sq/ft.
Original furnace (Installed 1976)is a Westinghouse Mod#foud154rd, Series 1kue, it has a single speed fan.
Original AC (Installed 1976)was a 4 ton unit. Its gone now so thats all I have on it.
New AC unit is an Armstrong 4 Ton, 12 Seer.
I keep the thermostat set on 72. When outside temp gets above 90, inside temp goes up. At 95 outside, 79 inside.
When the humidity outside is above 45% the inside humidity is 50% or higher. As the outside humidity goes up, so does the inside. We have condensation on our doors/windows at times and never had this happen before the new unit.
The duct work sweets to the point that its ruining the cieling tiles in the basement.
The unit once took six hours to drop the temp from 80 to 78. This was from 4:30pm to 10:30 pm, not during the heat of the day.
The old unit never caused any of these problems, kept the house at whatever temp I set it on no matter what the outside temp was.
