Your entire residence should be a refuge that’s warm and cozy in the winter and cool and comfortable in the summer. However, families who live in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the main floor.
This could just 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 they 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 trouble with your HVAC system. Some of these issues can be resolved relatively quickly while others might require more extensive and costly fixes. Here, the specialists at Classic Air 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 feeling 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 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 struggle to cool the upstairs effectively.
To fix these issues, homeowners could add extra insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioning unit is the proper size for the home, call an experienced HVAC company like Classic Air inspect the unit. A qualified professional also can help select 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 freezing upstairs, that could result in a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to seep through the home’s attic or walls and contribute to heat loss, creating colder temperatures on the upper levels. It’s essential 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 fundamental role in circulating conditioned air throughout different rooms of the building. However, problems with the ductwork can contribute to the upstairs being colder than the main level. A typical explanation 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 go downstairs, leaving insufficient airflow—which is the heated air—on the upper story.
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 poorly located, it can reduce air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can cause 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 examined by trusted experts like the team at Classic Air to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help enhance airflow and ensure a more consistent 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 a highly effective solution.
An HVAC zoning system separates the home into distinctive zones, which each have their own thermostat and damper system so the homeowner can modify the heating or cooling of each zone.
This system can be very helpful in situations where the upstairs of a multi-story home is very hot or really 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 My Upstairs So Humid?
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 downstairs.
A frequent reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may allow warm, humid air from outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also cause excess moisture in that area of a home.
To address humidity problems, homeowners can improve ventilation by using fans or opening windows to promote airflow. Proper 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 on the upper and lower floors.
