Your entire residence should be a refuge that’s warm and cozy in the winter season and cool and comfortable in the summer. However, residents in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the first floor.
This could just be due to the fact most thermostats in a house are on the main floor, which is where people spend the the majority 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 differences between the upstairs and downstairs could also be because of problems with your HVAC system. Some of these issues can be resolved somewhat quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Bain Heating & Air Conditioning will help you solve 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 common for the second floor of a home to get hotter than the ground floor. Poor 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 conditioner is not big enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.
To address these issues, homeowners could add additional insulation in the attic and make sure their home has adequate ventilation. If there’s concern the air conditioning unit is the ideal size for the home, call an experienced HVAC company like Bain Heating & 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 Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly 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 should are the insulation levels and the ductwork.
Inadequate insulation allows cold air to seep through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s crucial 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 fundamental role in circulating conditioned air throughout different rooms of the building. However, issues with the ductwork can result in the upstairs being colder than the main level. A frequently reported cause for this is improper airflow balance. The ducts may not be the correct size or configuration, creating an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, which creates insufficient airflow—which is the heated air—on the upper level.
Another possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper story or they aren't well positioned, it can limit air circulation and cause inferior heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced experts like the team at Bain Heating & 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 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 ground level of your home, an HVAC zoning system could be an effective solution.
An HVAC zoning system breaks the home 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 very useful in scenarios where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By implementing a zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots easily.

Why Is the Humidity So High 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 upstairs is more humid than the first floor.
A typical reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can cause 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 outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also lead to excessive moisture in that section of a home.
To address humidity problems, homeowners can add more 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 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.
