Every floor in your home should be a retreat that’s warm and cozy in the winter season and cool and comfortable in the summer. However, residents in some two-story homes find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could just be caused by the fact that most thermostats in a house are on the main floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so it makes sense to set the temperature according to how it feels on the first floor.
However, temperature differences between the upstairs and downstairs could also be due to issues with your HVAC system. Some of these difficulties can be fixed fairly quickly while others might necessitate more extensive and costly fixes. Here, the team at Mayeuxs AC & Heating will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is My Upstairs So Hot?
The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Lack of insulation in the attic or roof can exacerbate this issue by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the HVAC system is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.
To fix these issues, homeowners could add extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioning unit is the correct size for the home, call an experienced HVAC company like Mayeuxs AC & Heating inspect the unit. A qualified professional also can help find a unit that's better suited for your home if you want air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to leak through the home’s attic or walls and contribute to heat loss, causing colder temperatures upstairs. It’s essential 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 distributing conditioned air throughout different areas of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the correct size or configuration, resulting in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they are poorly located, it can reduce air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by experienced experts like the team at Mayeuxs AC & Heating to identify any imbalances, leaks or inadequacies. Sealing leaks and installing additional vents or adjusting existing ones can help increase airflow and ensure a better 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 useful solution.
An HVAC zoning system divides the home into distinctive zones, which each have their own thermostat and damper system so the homeowner can customize the heating or cooling of each zone.
This system can be particularly helpful in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By installing a zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots effortlessly.

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 the lower level.
A common reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can cause higher humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may let warm, humid air from outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also create unwanted moisture in that area of a home.
To correct humidity problems, homeowners can improve ventilation by installing fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Finding and repairing any leaks or plumbing issues is also imperative.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another useful tool to reduce humidity on the upper and lower floors.
