Can I close up vents in rooms not being used to improve air flow? Does it save money?
Generally, it is not a good idea to close off vents unless you know the layout of the ductwork. One room's supply vent may not be off the same trunk line as the other room that you are trying to improve. Also, the savings are usually insignificant and you run the risk of increasing humidity in the house. Contact us, we are happy to look at your situation and give you a recommendation.
Here are some of the problems we have found:
- The supply duct size to the room needs to be larger.
- A return needs to be added or increased
- The overall humidity in the house is too high
- Ductwork is leaking.
- Dirty filters
