Every floor in your home should be a refuge that’s warm and comfy in the winter season and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could just 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 as a result they tend to set the temperature according to how it feels on the first floor.
However, temperature differences between the upstairs and downstairs could also be because of issues with your HVAC system. Some of these challenges can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the team at HCE Systems will help you figure out why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hotter 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 normal for the second floor of a home to get hotter than the first floor. Insufficient insulation in the attic or roof can make this worse by allowing 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 fight to cool the upstairs sufficiently.
To fix these issues, homeowners could install extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the AC is the right size for the home, call an experienced HVAC company like HCE Systems 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 Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation lets cold air to seep 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 very important role in circulating conditioned air throughout different rooms of the building. However, issues with the ductwork can cause the upstairs being colder than the main level. A common cause 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 flow 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 not correctly positioned, it can reduce air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by skilled experts like the team at HCE Systems 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.
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 useful solution.
An HVAC zoning system breaks the home into distinctive 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 beneficial in situations where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By investing in 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 problem in multi-floor homes is when the upper floors are more humid than the first floor.
A frequent cause for excess upper floor humidity is weak ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing issues on the upper floor, that can also create unwanted moisture in that section of a home.
To correct humidity problems, homeowners can add more ventilation by installing fans or opening windows to promote airflow. Appropriate levels of 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 critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another helpful tool to control humidity on the upper and lower floors.
