Would closing the first floor vents cool the 2nd floor more?
Question:I have a two story townhouse and we just had the outside unit replaced. With alot of houses, the upstairs is really warm and the downstairs is really cold. I was wondering if I closed some of the a/c vents on the 1st floor if that would help the 2nd floor get more colder air. It might also keep the first floor from being so cold.
Answers:
It should help. I close my basement vent in the summer because I don't need a/c down there. I've also closed off two vents in the front of my downstairs to try to get more air in the back room, which is an addition. Do you have ceiling fans? They help circulate the air.
It certainly sounds like it makes sense since cold air goes down and heat rises; Try it for a month, and see.if it works.I can*t understand why some people keep their doors to the basement open for that very reason, after all the basement is already plenty cold.
That heating cooling thing is the very reason we opted to buy a ranch house rather than a two story/split level.
After visiting many display homes and finding just what you are describing.
If you only have one unit your problem maybe thats not enough.You could think about additional ductwork.You should also make sure you existing ductwork has no leaks.Sometimes there can be a tear around the evaporator coil and air is leaking.Tape everything really well.
Yes, it sounds good in theory, but, after we did that, our A/C man told us not to. Something about closing off the registers that makes the A/C work harder...bad for circulation?
Anyway, sorry I can't be more specific. Hopefully an A/C expert will sign on and answer your question in detail or prove my "expert" wrong.
Yes it will help- close all but 1 in each lower floor room,or all in lower floor rooms you don't use much.Heat rises so it's bound to warmer on higher floors,however closing lower vents will force more cool air to the upper floor.
I have closed a few vents in my basement and I have noticed a little bit of difference. I have heard that closing too many vents may also cause your unit to ice or freeze up. I've never had that happen though.
