Every floor in your home should be a refuge that’s warm and cozy in the winter and cool and comfortable in the summer. However, residents in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could merely be due to the fact most thermostats in a house are on the first floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so they set the temperature according to how it feels on the first floor.
However, temperature differences between the upstairs and downstairs could also be because of problems with your HVAC system. Some of these challenges can be solved somewhat quickly while others might require more extensive and costly fixes. Here, the specialists at Air Concepts of Middle Georgia will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hot Upstairs?
The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be traced to several factors. For starters, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Insufficient insulation in the attic or roof can worsen this problem by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not strong enough to cool the entire home, causing it to fight to cool the upstairs adequately.
To tackle these issues, homeowners could add extra insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the air conditioner is the ideal size for the home, call an experienced HVAC company like Air Concepts of Middle Georgia inspect the unit. A skilled professional also can help select a unit that's better suited for your home if you require air conditioning installation or replacement.
Why Is My Upstairs Colder/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that makes for a frosty night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation lets cold air to seep through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on the upper levels. It’s important to make sure your home has a solid, level layer of insulation in the attic and proper insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a very important role in circulating conditioned air throughout different areas of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the right size or configuration, causing an uneven distribution of air between the floors. This can cause more warm air to go downstairs, which creates insufficient airflow—which is the heated air—on the upper story.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they are poorly positioned, it can limit air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, lowering the overall efficiency of the HVAC system and actually making the temperature difference worse.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted HVAC pros like the team at Air Concepts of Middle Georgia to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help improve airflow and ensure a more consistent temperature balance between the upstairs and downstairs.
How You Can Fix a Hot or Cold Upstairs?
If your upstairs is hotter or colder than the ground level of your house, an HVAC zoning system could be a great solution.
An HVAC zoning system breaks the household into different zones, which each have their own thermostat and damper system so the homeowner can modify the heating or cooling of each zone.
This system can be particularly beneficial in situations where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can regulate the temperature independently in each zone, enabling them to address specific hot or cold spots effectively.

Why Is My Upstairs So Humid?
In addition to the upper story being hotter or colder than the rest of the house, another problem in multi-floor homes is when the higher levels are more humid than downstairs.
A common cause for excess upper floor humidity is poor ventilation on the upper floor, which can result in greater humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may allow warm, humid air from outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also cause excess moisture in that level of a home.
To deal with humidity problems, homeowners can increase ventilation by getting fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help prevent external moisture from entering the upstairs. Finding and repairing any leaks or plumbing issues is also critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another helpful tool to manage humidity in your home.
