Your entire residence should be a sanctuary that’s warm and cozy in the winter 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 rooms on ground level.
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 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 problems with your HVAC system. Some of these issues can be fixed fairly quickly while others might necessitate more extensive and costly fixes. Here, the team at Appalachian Heating 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 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 ground floor. Lack of insulation in the attic or roof can make this worse by allowing heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioner is not big enough to cool the entire home, causing it to struggle to cool the upstairs properly.
To deal with these issues, homeowners could put in more insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the air conditioner is the right size for the home, call an experienced HVAC company like Appalachian Heating inspect the unit. A skilled professional also can help locate 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 could result in a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation lets cold air to seep 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 solid, 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 very important role in distributing conditioned air throughout different locations of the building. However, issues with the ductwork can result in the upstairs being colder than the downstairs. A typical explanation for this is improper airflow balance. The ducts may not be the proper size or configuration, causing an uneven distribution of air between the floors. This can cause more warm air to flow 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 not correctly installed, it can restrict air circulation and cause substandard heating or cooling. Additionally, 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 checked by skilled professionals like the team at Appalachian Heating to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help increase 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 rest of your home, an HVAC zoning system could be an effective solution.
An HVAC zoning system breaks the residence into distinct 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 situations where the upstairs of a multi-story home is quite hot or really cold while the main floor is comfortable. By implementing a zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots easily.

Why Is My Upstairs So Humid?
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 higher levels 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 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 the house infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems on the upper floor, that can also create unwanted moisture in that section of a home.
To manage humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help stop external moisture from entering the upstairs. Locating 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 on the upper and lower floors.
