Your entire home should be a retreat that’s warm and cozy in the cold months 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 main floor.
This could merely be caused by the fact that most thermostats in a house are on the first floor, which is where people spend the most 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 caused by problems with your HVAC system. Some of these challenges can be fixed somewhat quickly while others might call for more extensive and costly fixes. Here, the specialists at Appalachian Heating 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 common for the second floor of a home to get hotter than the ground floor. Poor 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 HVAC system is not big enough to cool the entire home, causing it to have difficulty cooling the upstairs effectively.
To tackle these issues, homeowners could add additional insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the air conditioning unit is the correct size for the home, call an experienced HVAC company like Appalachian Heating inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you are considering air conditioning installation or replacement.
Why Is My Upstairs Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to seep through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s crucial to make sure your home has a thick, level layer of insulation in the attic and appropriate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a fundamental role in disseminating conditioned air throughout different rooms of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported explanation for this is improper airflow balance. The ducts may not be the proper size or design, resulting in 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 potential problem area in the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they aren't well positioned, it can limit air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted professionals like the team at Appalachian Heating to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in more 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 lower floors of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system divides the home 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 especially beneficial in scenarios where the upstairs of a multi-story home is quite hot or extremely 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 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 upper floors are more humid than downstairs.
A typical explanation for excess upper floor humidity is weak 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 permit warm, humid air from outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing concerns on the upper floor, that can also cause excess moisture in that area of a home.
To correct humidity problems, homeowners can increase ventilation by using 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. Identifying and repairing any leaks or plumbing issues is also extremely important.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another valuable tool to control humidity in your home.
