Third Floor Hot Because Heat Rises

Unfortunately for many owners of two story homes varying heat loss or heat gain is a common problem.

Third floor hot because heat rises. Physics is the challenge here because hot air rises and cold air sinks. These small heating and cooling systems focus on one room so you can control the temperature independently in each room where a unit is installed. Heat from any source naturally rises. Don t wait until summer to correct this issue.

In an enclosed room the hottest air will always be at the top or near the ceiling which is why ceiling fans are used to circulate heated air from top to bottom. This is because heated air is thinner and less dense than cooler air. So your upstairs has a natural tendency to be warmer than lower levels. Although true this is far from the main culprit of an uncomfortable upstairs and there is plenty that can be done to even the temperatures in your 2 story home.

Your roof absorbs a ton of heat from the sun unless you have a lot of shady tree cover. As the weather warms up indoor temperatures are starting to rise as well. Your third floor is hotter than the rest of the house in the summer because the heat gets trapped there. All that hot air moves through your roof into the attic and ultimately into your top.

First why is the second floor hot. The most common rationale for a warmer second floor is that heat rises.
