Physics is the challenge here because hot air rises and cold air sinks.
Upstairs and downstairs air conditioning.
Enough air must go through the air conditioner.
If you re trying to get the most efficiency out of a central air conditioner.
Be careful not to fully close all downstairs air supply registers.
You are literally rerouting the circulation of the air pushed out through your air conditioner.
Leave all of the upstairs doors open.
Less dense air rises above colder more dense air.
Key reasons it gets hotter upstairs.
So your upstairs has a natural tendency to be warmer than lower levels.
As a result two story homes are commonly cooler downstairs than they are upstairs.
Increasing the air conditioning in.
A lower cooling load in upstairs living spaces allows more moderate a c thermostat settings and avoids over cooling downstairs rooms.
Why is my air conditioning working upstairs but not downstairs.
Your roof absorbs a ton of heat from the sun unless you have a lot of shady tree cover.
Central air conditioners work by blowing chilled air into the home.
If you ve been having problems sleeping during the summer because it s too hot upstairs you re not alone.
Opening upstairs cold air supply registers fully and all but closing downstairs air supply registers helps direct the cold air upstairs.
As air heats the density decreases.
It happens because of the laws of thermodynamics.
