Your entire residence should be a retreat that’s warm and toasty 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 main floor.
This could merely be due to the fact most thermostats in a house are on the first 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 caused by trouble with your HVAC system. Some of these difficulties can be sorted out relatively quickly while others might necessitate more extensive and costly fixes. Here, the professionals at B&D 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 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 main floor. Lack of insulation in the attic or roof can exacerbate this issue by permitting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioner is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs effectively.
To fix these issues, homeowners could add more insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioner is the correct size for the home, call an experienced HVAC company like B&D Air Conditioning inspect the unit. A qualified 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 extremely chilly upstairs, that can cause a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation permits cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. It’s important to make sure your home has a deep, 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 distributing conditioned air throughout different areas of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the correct size or design, 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 potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper floor or they are poorly installed, it can reduce air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can lead to air loss, reducing the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by experienced experts like the team at B&D Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help enhance 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 rest of your house, an HVAC zoning system could be a great solution.
An HVAC zoning system divides the household into distinct 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 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 implementing a zoning system, homeowners can control the temperature independently in each zone, making it possible for them to address specific hot or cold spots effectively.

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 lower level.
A common cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in increased humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may allow warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also lead to excessive moisture in that section of a home.
To manage humidity problems, homeowners can increase 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 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 valuable tool to reduce humidity in the residence.
