How does forced air work?
Whenever your AC unit is running, it is drawing air in through return vents, cooling the air, and then forcing the air back out through the supply ducts and into the living space. When the temperature in the living space drops to the setpoint, the thermostat responds by shutting the AC down. 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. This cycle of cooling down and heating up is one of the main reasons homes with forced-air heat never truly enjoy a consistent temperature, but there are some things you can do to minimize the upstairs/downstairs difference.

Why is my upstairs room hot?
One of the biggest reasons the upstairs gets so hot is that the current sealing, insulation, and ventilation systems are not working correctly. On the sealing side of things, gaps in the home’s structure can go unnoticed and quickly add up, causing air conditioning to be wasted.
Why is the attic hot?
This is most notable in the case of attics. Since attics are often under-insulated, poorly sealed, and poorly ventilated, the temperature environment can be drastically different in an attic than in the rest of the home. During the summer, this leads to the hot air from the attic seeking out the cooler, conditioned floors below. This makes it harder for your cooling system to do its job efficiently, driving up energy costs and bringing down home comfort.
What happens if you have an air conditioner on the first floor?
If there is an air conditioner on the first floor and nowhere else, the home is going to be working too hard to push conditioned air throughout the entire building.

What is the biggest source of air leakage in a home?
One of the biggest improvements comes from sealing and insulating the attic access, one of the biggest sources of air leakage in the home. When the attic and attic access are not properly sealed and insulated, the hot air coming in through the roof can leak into the lower floors of the home.
