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 because most thermostats in a house are on the first floor, which is where people spend the the majority of time—in the living room, kitchen, etc.—so they 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 problems with your HVAC system. Some of these issues can be resolved relatively quickly while others might necessitate more extensive and costly fixes. Here, the team at Childress Heating & AC will help you figure out why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hot Upstairs?
The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be traced to several factors. For starters, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Lack of 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 air conditioner is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To deal with these issues, homeowners could add extra insulation in the attic and make sure their home has proper ventilation. If there’s concern the AC is the right size for the home, call an experienced HVAC company like Childress Heating & AC inspect the unit. A qualified professional also can help locate 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 could result in a frosty night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to filter through the home’s attic or walls and contribute to heat loss, creating colder temperatures on higher floors. It’s essential 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 fundamental role in distributing conditioned air throughout different rooms of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the downstairs. A typical reason for this is improper airflow balance. The ducts may not be the proper size or configuration, creating an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, leaving insufficient airflow—which is the heated air—on the upper story.
Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they are poorly positioned, it can restrict air circulation and cause inadequate 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 determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by skilled professionals like the team at Childress Heating & AC to identify any imbalances, leaks or inadequacies. Sealing leaks and installing additional vents or adjusting existing ones can help improve airflow and ensure a more even 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 home, an HVAC zoning system could be a great solution.
An HVAC zoning system breaks the home 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 too hot or extremely cold while the main floor is comfortable. By investing in a zoning system, homeowners can regulate the temperature independently in each zone, allowing them to address specific hot or cold spots easily.

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 higher levels are more humid than downstairs.
A common explanation 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, poor 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 lead to excessive moisture in that area of a home.
To address humidity problems, homeowners can increase ventilation by installing 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. Locating and repairing any leaks or plumbing issues is also imperative.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another valuable tool to control humidity in the residence.
