I hope theres someone here that can kinda help me. My mothers house has split system a/c and heating.
I dont know how many btu or anything about it.
The system 3 returns 1 upstairs, 1 down stairs in the open area, and 1 vent on the system.
2 ducts coming out of the top; which spilt off to many different ducts. Some upstairs and some downstairs.
The thing is she has all the one downstairs closed off. She doesnt want to heat downstairs now. But the returns down stairs are still open. And this is how its been since shes had the system installed.
Now She is going to call the guy out tomorrw but I would like to know.
Are having the ducts downstairs closed messing up the heating?
Does she just need to close off the returns downstairs?
Open the ducts and cool downstairs?
Thanks for the help.
