Second Floor Too Hot?

Have you ever wondered why the second floor of your home is much hotter than the first floor? Even though you’ve tried turning up the air conditioning, and lowering the temperature in your home, it still seems that the second floor is too hot. Why does this happen? First off, heat has a natural tendency to rise. Below we’ve listed some of the most common reasons why your second floor in your home is hotter than the first floor.

Hot Air Rises

Most commonly, heating and air conditioning units are installed on the first floor of a home so when the system is pushing cool air into your house, it is pushing the hot air upwards. There are a few ways to tell how hard your system is working to cool off the second level of your home: How old your home is, how many rooms there are within your home, and how well equipped your system is for cooling.

Insulation, Seals, and Ducts

Your air conditioning unit will have to work much, much harder if you insulation and ductwork is faulty. This can not only make it more difficult to cool your home, but also take a chunk out of your wallet as well. Ducts distribute the cool air from your system throughout your house and if the ducts are leaky, or improperly installed, your system will have to work much harder to cool your home. This means your system is working inefficiently, which make your system work overtime and drive up your monthly costs!


The third most common reason why your second floor is hotter than the first floor in your home may be due to a hot roof. If your roof is exposed to direct sunlight instead of being blocked by trees and shading, this can also cause your second floor to heat up. Heat travels through the attic to the second floor which also makes it more difficult to keep the second floor cool.

How To Fix It

Now that we have identified the cause of the issue, we can figure out how to fix it! There are many ways to reduce the heat on the second level of your home and some of them include changing filters, insulating your attic and windows, and fan settings just to name a few.

Change Your Filters

Changing dirty filters is one of the easiest and quickest ways to reduce heat in your home. Dirty filters trap conditioned air from getting through to your home. Make sure filters are changed every three to six months for optimal air conditioning results.

Insulate Windows

This is important especially in homes that are older. Windows with cracks in the sealing, or holes and gaps allow hot air from outside to enter the home. By replacing, fixing, and insulating cracked windows, the hot air especially on the second floor of your home will be reduced.

Insulate The Attic

Insulating your attic properly will also do wonders to the heat level in the second level of your home. Adding an attic fan will also help reduce the amount of hot air in your home and can help keep moisture out as well.

Fan Settings

Turning your HVAC system settings from “auto” to “on” on the thermostat will also help push out hot air on the second floor. Keeping the fan running allows your system to cycle less often so it won’t use as much energy.
