Cooler air settles into the lower areas of the house (usually where the thermostat is located); while heat from the outside begins to warm things up again. Because heat rises, the temperature on the second floor rises first, causing the second floor to feel warmer than the first floor.
Why is the second floor of my house so much hotter?
Blame physics: hot air rises while cold air sinks. That means your upstairs typically gets hotter than your lower levels, even if your air conditioner’s working in overdrive. Your roof’s hot, too: Unless you have shady tree cover, your roof absorbs a ton of heat from the sun.
Why is it hotter on the second story of a building than the first?
In winter and summer, a two-story home can have uneven heat distribution, with a hot upstairs and a cold downstairs. Heat rises, so excess heat collects in the second story, especially if you have a powerful air conditioning system on the first floor.
Is it hotter on the first or second floor?
If you live in a two-story home, you may have noticed that the second floor is significantly hotter than the first floor. Warm air rises and the naturally warm air is going to rise to the highest floor. If you have an HVAC unit on the first floor, hot air has to be pushed out so cool air can enter a room.
Why is upstairs always hotter than downstairs?
Why is my upstairs always too hot? Warm air rises. It’s a fact of nature: warm air rises above cool air. So at any given time in your home, your upper levels likely contain more warm air than the lower levels because warm air tends to gravitate up toward them.
Why is my upstairs so hot in summer?
Poor Sealing, Insulation, and Ventilation One of the biggest reasons the upstairs gets so hot is that the current sealing, insulation, and ventilation systems are not working correctly. To top it all off, improper ventilation can result in an inadequate amount of airflow, making it difficult to stay cool naturally.
How do you balance upstairs and downstairs temperature?
Here’s what you do: set your upstairs thermostat to your desired temperature goals, and then set your downstairs unit to be two degrees warmer. For most homes, this naturally encourages a temperature balance that’s comfortable and right at your desired temperature goals.
Why is my upstairs so much hotter than downstairs in winter?
The Simple Explanation for Why It’s Hot Upstairs and Cold Downstairs. Cold air is denser than warm air so it stays on the bottom while warm air rises. That’s why the downstairs can feel so chilly while the upstairs is toasty in the winter.
Are lower floors colder than upper floors?
The most obvious reason why your top-floor apartment is hotter than the lower units is sun exposure. Lower floor apartments are generally cooler because their sunlight exposure is limited to the side of the building. As a result, roofing materials have less of an impact on the amount of heat they receive.
Are higher floors colder?
The heat from the sun penetrates the upper floors and makes them more prone to warmer temperatures. The reverse applies in winter, the heat transfer from the upper floors to the external atmosphere is higher. Heat escapes relatively faster from the upper floors resulting in colder temperature in those floors….
Why is the second floor colder than the first floor?
You’re Losing Heat Through the Attic So, why is the second floor naturally colder than the first? Well, heat indeed rises. So, the heat keeps going past the rooms on the second floor. From there, it escapes through any uninsulated points — often through the roof.
Why is it best to place a room heater on the floor but an air conditioner near the ceiling?
The heater is placed near the floor because the air currents move upwards so the hot air fills up the whole room. Whereas, an air conditioner is placed near the ceiling because the cold breeze tends to settle down. So it is placed near the ceiling so that the whole room cools down.
How do you get airflow to the second floor?

Why is my house warm downstairs but cold upstairs?
This might be in a room downstairs that has the door closed. When that room is heated, the furnace will go off and leave the rest of the house at a temperature that is cooler. So moving the thermostat control or regulating whether the room is closed off may help. Need to adjust heat vents.
