Your roof absorbs a ton of heat from the sun unless you have a lot of shady tree cover.
Cold first floor hot second floor.
I have a 12 year old house with a basement and a first and 2nd floor.
My 2nd floor of my 12 year old house is really hot.
If your hvac unit is on the first floor it has to push hot air out as cooler air enters a room.
The number of rooms in.
Physics is the challenge here because hot air rises and cold air sinks.
Additionally for homes with vaulted ceilings much of that.
There are a few factors that determine how hard your hvac unit has to work to cool your second floor.
That means the system has to work harder to distribute cool air to the second floor.
With a cold first floor or a warm second floor balance has to be restored in order to rectify the situation.
Reducing the airflow to the first floor with also ensure longer cycle times as your thermostat is most likely on the first floor as well.
Zoning systems allow you to control the temperature independently from a thermostat placed on each floor.
How to keep a second floor warmer.
For 3 in theory this method should allow more places for the hot air to be moved out of a second floor but may also suffer from limitations due to your homes construction the limits of your present central air system and the location of the added vent ducts.
When the first floor reaches your target temperature it shuts off cooling or heating for the whole house regardless of whether the second floor has also reached that temperature.
Keep in mind that heat rises.
I have even closed all of the vents on the 2nd floor and it is still hot.
In the majority of homes it means making improvements to how the home is air sealed how it s insulated and how it s ventilated.
This just started happening last winter.
During system operation while the ground floor of the home remains stubbornly chilly the upper level rooms become unpleasantly warm.
Longer cycle times mean more cool air is getting to the second floor.
The goal obviously is to create air balance throughout the home year round so it is heated and cooled more evenly.
Two story homes often require more cool airflow to the second floor during the summertime and more warm airflow on the first floor in the wintertime.
All that hot air moves through your roof into the attic and ultimately into your top floor.
If the second floor of your home stays cold in the winter even when the first floor is toasty it may indicate that your home is improperly insulated or ventilated.
Slightly restricting airflow to your first floor will increase the volume of cool air to your second floor balancing out comfort.
I would appreciate any help.
