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, owners of some homes with multiple levels 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 discrepancies between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these issues can be fixed fairly quickly while others might call for more extensive and costly fixes. Here, the team at Comfort Concepts Heating & Air Conditioning will help you solve 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 traced to several factors. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the ground floor. Insufficient insulation in the attic or roof can make this worse by permitting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not strong enough to cool the entire home, causing it to fight to cool the upstairs adequately.
To tackle these issues, homeowners could add extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the air conditioner is the proper size for the home, call an experienced HVAC company like Comfort Concepts 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 So Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that can cause an ice-cold 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 allows cold air to leak through the home’s attic or walls and contribute to heat loss, causing colder temperatures on higher floors. It’s important to make sure your home has a thick, 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 critical role in disseminating conditioned air throughout different areas of the building. However, problems with the ductwork can result in the upstairs being colder than the lower floor. A frequently reported reason for this is improper airflow balance. The ducts may not be the right size or design, creating an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing 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 level or they aren't well installed, it can limit air circulation and cause substandard heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, reducing 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 Comfort Concepts Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help improve airflow and ensure a better temperature balance between the upstairs and downstairs.
How You Can Fix a Hot or Cold Upstairs?
If your upstairs is hotter or colder than the rest of your residence, an HVAC zoning system could be an 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 customize the heating or cooling of each zone.
This system can be particularly beneficial in instances where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By setting up a zoning system, homeowners can regulate the temperature independently in each zone, making it possible for them to address specific hot or cold spots effectively.

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 higher levels are more humid than the first floor.
A common cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in greater humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may let warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also create excessive moisture in that section of a home.
To deal with humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Appropriate levels of 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 reduce humidity on the upper and lower floors.
