Your entire home should be a refuge that’s warm and comfy in the cold months 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 first floor.
This could just be caused by the fact that 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 as a result they tend to set the temperature according to how it feels on the first floor.
However, temperature discrepancies between the upstairs and downstairs could also be caused by issues with your HVAC system. Some of these difficulties can be fixed somewhat quickly while others might call for more extensive and costly fixes. Here, the team at Paniccia Heating & Cooling will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hotter Upstairs?
The phenomenon of the upstairs of a two-story home feeling hotter than the downstairs can be traced to several factors. First, 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 exacerbate this issue by permitting 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 struggle to cool the upstairs adequately.
To tackle these issues, homeowners could install extra insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the AC is the correct size for the home, call an experienced HVAC company like Paniccia Heating & Cooling 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 Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to seep through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures upstairs. It’s important to make sure your home has a thick, 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 fundamental role in circulating conditioned air throughout different areas of the building. However, issues with the ductwork can cause the upstairs being colder than the lower floor. A common explanation for this is improper airflow balance. The ducts may not be the correct size or design, creating an uneven distribution of air between the floors. This can cause more warm air to flow 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 aren't well installed, it can restrict air circulation and cause substandard heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, decreasing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by skilled experts like the team at Paniccia Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help increase airflow and ensure a better temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the ground level of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system breaks the residence 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 very useful in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can control the temperature independently in each zone, allowing them to address specific hot or cold spots effectively.

Why Is it So Humid Upstairs?
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 upstairs is more humid than the first floor.
A frequent cause for excess upper floor humidity is poor ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing concerns on the upper floor, that can also cause unwanted moisture in that area of a home.
To correct humidity problems, homeowners can add more 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 protect against external moisture from entering the upstairs. Identifying 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 useful tool to manage humidity on the upper and lower floors.
