Your entire home should be a sanctuary that’s warm and comfy in the winter and cool and comfortable in the summer. However, owners of some homes with multiple levels 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 main 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 variations between the upstairs and downstairs could also be caused by issues with your HVAC system. Some of these issues can be solved relatively quickly while others might necessitate more extensive and costly fixes. Here, the team at Redhawk Heating & Air Conditioning will help you solve 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 getting hotter than the downstairs can be traced to several factors. Number one, heat rises, so it’s common for the second floor of a home to get hotter than the first floor. Poor insulation in the attic or roof can exacerbate this issue by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the HVAC system is not strong enough to cool the entire home, causing it to struggle to cool the upstairs properly.
To deal with these issues, homeowners could install additional insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the air conditioner is the ideal size for the home, call an experienced HVAC company like Redhawk Heating & Air Conditioning 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 Colder/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that can cause a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it ought 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, causing colder temperatures upstairs. It’s crucial to make sure your home has a deep, 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 critical role in circulating conditioned air throughout different rooms of the building. However, issues 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 right size or design, causing 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 level.
Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly installed, it can reduce air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted professionals like the team at Redhawk Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help increase airflow and ensure a better 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 house, an HVAC zoning system could be an effective solution.
An HVAC zoning system separates the home into distinct zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.
This system can be very useful in scenarios where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By installing a zoning system, homeowners can control the temperature independently in each zone, enabling them to address specific hot or cold spots easily.

Why Is it So Humid 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 the lower level.
A frequent explanation for excess upper floor humidity is weak ventilation on the upper floor, which can cause 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 infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also cause extra moisture in that level of a home.
To address humidity problems, homeowners can improve ventilation by getting 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. Locating 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 helpful tool to manage humidity on the upper and lower floors.
