I hope you folks can shed some light on this for me. For 3 years now i've been in my house, it was new when i bought it. I've got a 3 ton unit outside that runs both the upstairs and downstairs, my whole house is only about 1600 sq feet. I live in the South and of course in the summer my upstairs get really warm, my upstairs consists of 2 small bedrooms of about 121 square feet each, a small hallway that is about 50 sq feet and a full back about 50-60 square feet for a total of about 350 square feet total upstairs. I've gotten 3 quotes and each one of them suggests installing a new 1.5 ton unit and none of them have mentioned anything about dampners. The other day i got a quote from a friend of mine who told me that this space is too small for a 1.5 ton unit and it would not get rid of all the humidity in the upstairs and he recommended dampners. This is somthing new for me and he explained to me that he would install a second thermostat upstairs and it would control the opening and closing of the dampners. My biggest question is why didnt the other 3 quotes i got mention something about dampners and also can someone tell me if they have dampners do they work fairly well?
Thanks in advance.
