Your entire residence should be a refuge that’s warm and comfy 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 first floor.
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 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 issues with your HVAC system. Some of these challenges can be fixed somewhat quickly while others might necessitate more extensive and costly fixes. Here, the specialists at Evenaire Heating & Air Conditioning will help you figure out 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 attributed 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. Not enough insulation in the attic or roof can worsen this problem by permitting 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 struggle to cool the upstairs properly.
To tackle these issues, homeowners could put in extra insulation in the attic and make sure their home has proper ventilation. If there’s concern the air conditioning unit is the right size for the home, call an experienced HVAC company like Evenaire Heating & Air Conditioning inspect the unit. A knowledgeable 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 Colder/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that makes for a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it should 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 on the upper levels. It’s crucial to make sure your home has a thick, 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 disseminating conditioned air throughout different rooms of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported explanation for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, resulting in an uneven distribution of air between the floors. This can cause more warm air to go 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 not correctly installed, it can reduce air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can lead to air loss, decreasing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted experts like the team at Evenaire Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help increase airflow and ensure a more even 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 an effective solution.
An HVAC zoning system divides the home into distinctive 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 effective in instances where the upstairs of a multi-story home is quite hot or really cold while the main floor is comfortable. By installing a zoning system, homeowners can manage the temperature independently in each zone, allowing 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 higher levels are more humid than downstairs.
A frequent explanation for excess upper floor humidity is weak ventilation on the upper floor, which can produce higher humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may let 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 correct humidity problems, homeowners can improve ventilation by using 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 valuable tool to control humidity in the residence.
