I am planning to run an 8 round conduit from basement to attic and in attic split that into four 6 conduit and take it into the middle of 4 bedrooms in the 2nd floor.
How to push all the cold air to upper floor.
So your upstairs has a natural tendency to be warmer than lower levels.
As the system tries to push more air into rooms.
Fully open each vent to allow for maximum air flow.
Locate all of the vents on the second floor and check to see if they are blocked in any way.
Unfortunately a forced air hvac system is not always the best solution for a 2 story home.
I will need to figure out how to have a valve system in place so that only the valve to the 6 duct will only.
Then it can mix all the air lowering the temperature.
They sit on the floor on casters and use an adapter kit to vent the hot air through a hose running through a window a wall or a sliding glass door.
Portable air conditioners are similar to window units in operation.
Forced air systems have a hard time providing a consistent temperature throughout your home.
All that hot air moves through your roof into the attic and ultimately into your top.
You can pay a hvac installer to install dampers in the air ducts so you can reduce the flow of force air feeding the basement by adjusting the dampers.
Remove any furniture blocking the air flow.
You can move them from room to room.
In this system a window opening in the lower part of the home brings air into the home which becomes cool from basement temperatures while an opening on the upper floor pulls hot air out.
If a heater or air conditioning unit sits in a basement and is separated from an upstairs bedroom by a garage attic and or crawl space air can get lost in those areas along the way reducing the amount of cool air that makes it to the upstairs room.
An inline duct fan near the bedroom ceiling vent will pull and an 8 duct fan in the basement will push.
Another fix is have them install a second thermostat to the hvac system and split the ducts into 2 zones.
They help prevent the cold air from settling near the floor of the upstairs rooms whisking it up in an airy cycle.
Sometimes the difficulty is caused by leaky joints ducts or even the layout of a home.
Physics is the challenge here because hot air rises and cold air sinks.
Your roof absorbs a ton of heat from the sun unless you have a lot of shady tree cover.
Main advantages they are easy to install and use.
The air conditioning system will have to push cool air up from the basement or first floor.
Upper floor rooms can be difficult to heat and cool.
