Using separate central air conditioning units for each floor allows you to maintain a.
Air conditioning second floor only.
As air heats the density decreases.
Less dense air rises above colder more dense air.
Ductwork services second floor rooms through ceiling registers.
You could turn the ac down even more.
Ducts run through closets on their way to first floor rooms.
In some cases it s because the system is outdated.
The hot summer days and especially the nights bring back one of the most common home comfort problems.
The most common complaint regarding imbalanced temps and hvac units is that it cools the first floor but not the second floor.
The challenge is to install adequately sized ductwork from the second floor hallway to the basement or furnace room.
We re thinking of putting central air in our house.
Units older than 10 years should be upgraded.
Depending on the size you get you can spend as little as 150 or a good unit and less than 20 each month to run it every day.
The hot air from the second floor rooms can be collected in the hallway and sent back to the air conditioner.
To maintain balance a return duct allows air back into the fan and coil system and a filter placed inside the duct keeps the cooled air free of airborne dust and dirt.
Of course this means that your second floor has not yet sufficiently cooled.
However when the thermostat senses that the temperature on the main floor is the temperature your hvac system has been set for it will turn off the ac.
Central ac on second floor only.

Positioning a window air conditioner in those places will allow the unit to better regulate the heat on your second floor.
You can even air seal your attic to prevent heat from seeping in.
Window ac units are quite affordable too.
Trees shading the second floor reduce the impact of direct sunlight.
Hot air rises so the second floor is naturally going to be warmer.
The second floor is often much warmer than the first so one area of the house often seems too hot or two cold.
Ideally we d like a two zone system or two separate systems one located in the attic to serve the second floor and one in the basement to serve the first floor but we aren t sure if we can currently afford that.
The temperature differences are more pronounced the greater the height of the column of air.
Despite your air conditioner repair man saying the ac is tuned up and running properly the bedrooms on the second floor are so hot many in the family choose to sleep downstairs.
Also adding an attic fan will help cool things down by circulating the air up there and decreasing the amount of hot air reaching your second floor.
Different temperatures on different floors of your home can signal an issue with how your air conditioning system works.
