Every floor in your home should be a refuge that’s warm and cozy in the winter season 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 main floor.
This could merely be caused by the fact that most thermostats in a house are on the ground floor, which is where people spend the the majority 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 due to trouble with your HVAC system. Some of these issues can be fixed relatively quickly while others might necessitate more extensive and costly fixes. Here, the team at Evenaire Heating & Air Conditioning will help you determine 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. First, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Insufficient insulation in the attic or roof can worsen this problem by allowing 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 fight to cool the upstairs effectively.
To tackle these issues, homeowners could add additional insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the air conditioner is the ideal size for the home, call an experienced HVAC company like Evenaire Heating & Air Conditioning inspect the unit. A qualified professional also can help find a unit that's better suited for your home if you want air conditioning installation or replacement.
Why Is My Upstairs Always Cold/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 permits cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures upstairs. It’s essential 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 fundamental role in circulating conditioned air throughout different locations of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported cause for this is improper airflow balance. The ducts may not be the correct 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 upper level.
Another factor with ductwork is the layout of the supply and return vents. If there are fewer vents on the upper story or they are not correctly installed, it can limit air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can cause 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 checked by skilled professionals like the team at Evenaire Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help improve airflow and ensure a better temperature balance between the upstairs and downstairs.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the lower floors of your house, 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 control the heating or cooling of each zone.
This system can be especially beneficial in scenarios where the upstairs of a multi-story home is very hot or extremely cold while the main floor is comfortable. By setting up 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 problem in multi-floor homes is when the upstairs is more humid than the lower level.
A frequent reason for excess upper floor humidity is poor ventilation on the upper floor, which can produce 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 outside infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also cause extra moisture in that level of a home.
To correct humidity problems, homeowners can add more ventilation by installing fans or opening windows to promote airflow. Adding more 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 the residence.
