Is Zoned/Heating Cooling worth it?
We live in a 2 story home that is around 3900 sq. feet. It has a 2 story open foyer so only have 1 zone heating/cooling the main floor and uppper level.
Now I am finishing my basement. The finished area will be around 1300 square feet.
Right now when we walk down to our basement we have 2 doors. One goes to the utility area and the other goes to the unfinished area.
We were thinking of removing the door to the unfinished area. We felt that it will look nicer to walk into an open area and make basement look like a part of the home.
A friend of mine pointed out that removing the door will result in heat escaping up easily. He also recommended making basement a separate zone.
We live in MN so summers are not a problem. However winter heating costs can be high.
HVAC work is nearly finished. I am trying to determine if I should spending the money for keeping basement on a separate zone. How much should I expect to pay?
Will removing the door make things worse with our without a separate door?
I have to make my decision today so I will appreciate any thoughts you have on this.
