Your entire residence should be a sanctuary that’s warm and cozy in the winter season and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could simply be caused by the fact that 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 it makes sense 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 trouble with your HVAC system. Some of these difficulties can be solved relatively quickly while others might call for more extensive and costly fixes. Here, the professionals at 1st Choice Heating & Air Conditioning will help you solve 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 chalked up to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the ground floor. Not enough 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 conditioner is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs effectively.
To tackle these issues, homeowners could install additional insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the air conditioner is the correct size for the home, call an experienced HVAC company like 1st Choice Heating & Air Conditioning inspect the unit. A skilled professional also can help select 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 a frosty 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 lets cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on the upper levels. It’s crucial to make sure your home has a thick, level layer of insulation in the attic and adequate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a critical role in distributing conditioned air throughout different rooms of the building. However, issues with the ductwork can contribute to the upstairs being colder than the downstairs. A frequently reported explanation for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, causing an uneven distribution of air between the floors. This can cause more warm air to go downstairs, causing 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 limit air circulation and cause substandard heating or cooling. Additionally, 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 find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted professionals like the team at 1st Choice Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help enhance airflow and ensure a more even 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 residence, an HVAC zoning system could be a great solution.
An HVAC zoning system divides 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 particularly effective in scenarios where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By installing a zoning system, homeowners can control the temperature independently in each zone, making it possible for them to address specific hot or cold spots effortlessly.

Why Is the Humidity So High Upstairs?
In addition to the upper story being hotter or colder than the rest of the house, another issue in multi-floor homes is when the upstairs is more humid than downstairs.
A common cause for excess upper floor humidity is inadequate 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 permit warm, humid air from outside infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also cause unwanted moisture in that area of a home.
To fix humidity problems, homeowners can improve ventilation by using fans or opening windows to promote airflow. Adding more insulation in the attic and better sealing the attic and walls can help stop 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 reduce humidity in the residence.
