A tech last week recommend that I have some dampers installed in my ductwork in order to properly balance the air flow in the house. There are two duct runs from the air handler. It is as follows:
1. First duct run (flex) ends in a distribution box with five flex ducts stemming from it. Two of the flex ducts go to the master bedroom, another duct runs to the water closet in the master bedroom, the other duct runs to the master bedroom, and the last one goes to the closet in the master bedroom. This master suite (Which the air handler is located right above) gets too cold and too hot (in summer and winter) relative to the house. This is particularly where I would like to have dampers installed. Currently, we have one register completely closed in the bedroom, and both closet registers completely closed (one in the water closet and regular closet). In other words, we only have two of the five vents open and that provides enough air. Does having too many dampers (reducing air flow) hurt our air conditioning system? Ideally, I would like to have dampers on all five of these ducts and completely shut off the closets and reduce air flow the rest of the vents. Would this be OK or will it hurt my system? I hope this would push air throughout the rest of the house more efficiently.
2. Second duct run (flex) goes to one distribution box with five runs, at the end of the box, more flex duct runs to another box with five runs, and finally more flex runs to a third box.
I had a tech at my house last week and he said the ductwork design is poor. He recommened dampers to help with the balancing. What do you think? Could I just have them installed on the individual duct runs that go to the master bedroom and bathroom?
some stats on the house. 3 ton air conditioner (Comfortmaker), roughly 1,500SF house located near Greensboro, NC. system was installed brand new in 1996. Recently was serviced and had one pound of freon added to the system.
Thanks for your help in advance!
