Every floor in your home should be a sanctuary that’s warm and cozy in the cold months and cool and comfortable in the summer. However, residents in some two-story homes 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 first floor, which is where people spend the greatest amount 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 variations between the upstairs and downstairs could also be because of problems with your HVAC system. Some of these challenges can be resolved somewhat quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Redhawk Heating & Air Conditioning will help you determine 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 common for the second floor of a home to get hotter than the ground floor. Not enough 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 conditioning is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.
To tackle these issues, homeowners could put in additional insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the AC is the correct size for the home, call an experienced HVAC company like Redhawk Heating & Air Conditioning inspect the unit. A qualified 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 could result in an ice-cold 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 higher floors. It’s crucial to make sure your home has a solid, 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 critical role in circulating conditioned air throughout different locations of the building. However, problems with the ductwork can cause the upstairs being colder than the lower floor. A common reason 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, which creates insufficient airflow—which is the heated air—on the higher floors.
Another factor with 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 restrict air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, decreasing 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 examined by skilled experts like the team at Redhawk Heating & Air Conditioning 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 rest of your home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system breaks the residence 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 useful in situations where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By implementing a zoning system, homeowners can control the temperature independently in each zone, enabling them to address specific hot or cold spots effortlessly.

Why Is My Upstairs So Humid?
In addition to the upper story being hotter or colder than the rest of the house, another challenge in multi-floor homes is when the upstairs is more humid than the first floor.
A common reason for excess upper floor humidity is poor ventilation on the upper floor, which can result in greater humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may allow warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also cause excessive moisture in that section of a home.
To deal with humidity problems, homeowners can add more ventilation by installing fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Finding 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 helpful tool to reduce humidity on the upper and lower floors.
