Your entire home should be a sanctuary that’s warm and toasty in the cold months and cool and comfortable in the summer. However, owners of some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could simply be due to the fact most thermostats in a house are on the main floor, which is where people spend the the majority 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 differences between the upstairs and downstairs could also be due to issues with your HVAC system. Some of these difficulties can be solved relatively quickly while others might require more extensive and costly fixes. Here, the team at J.L. Brady Company LLC will help you figure out 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 getting hotter than the downstairs can be attributed to several factors. For starters, heat rises, so it’s natural for the second floor of a home to get hotter than the ground floor. Insufficient insulation in the attic or roof can exacerbate this issue by allowing 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 sufficiently.
To fix these issues, homeowners could put in more insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the AC is the right size for the home, call an experienced HVAC company like J.L. Brady Company LLC inspect the unit. A skilled professional also can help find a unit that's better suited for your home if you need 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 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 should are the insulation levels and the ductwork.
Inadequate insulation allows cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s important to make sure your home has a deep, 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 distributing conditioned air throughout different locations of the building. However, problems with the ductwork can contribute to the upstairs being colder than the main level. A common cause for this is improper airflow balance. The ducts may not be the correct size or configuration, causing an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing insufficient airflow—which is the heated air—on the upper level.
Another possible issue with the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they are poorly positioned, it can limit air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can lead to air loss, reducing the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced HVAC pros like the team at J.L. Brady Company LLC to identify any imbalances, leaks or inadequacies. Sealing leaks and adding 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 useful solution.
An HVAC zoning system separates the household into different 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 extremely cold while the main floor is comfortable. By implementing a zoning system, homeowners can regulate the temperature independently in each zone, making it possible for 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 upper floors are more humid than the lower level.
A common cause for excess upper floor humidity is weak ventilation on the upper floor, which can produce higher 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 outside the house infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems on the upper floor, that can also cause excess moisture in that level of a home.
To correct humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help prevent 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.
