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 multi-level residences find the upper floor is stubbornly hotter or colder than the main floor.
This could just be due to the fact most thermostats in a house are on the ground 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 variations between the upstairs and downstairs could also be due to issues with your HVAC system. Some of these challenges can be sorted out relatively quickly while others might call for more extensive and costly fixes. Here, the specialists at Taylor's Heating & Air Conditioning 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 getting hotter than the downstairs can be traced to several factors. For starters, 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 make this worse by allowing heat transfer from the roof into the upstairs rooms.
Another common reason is that the HVAC system is not strong enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To fix these issues, homeowners could add additional 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 Taylor's Heating & Air Conditioning inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you are considering air conditioning installation or replacement.
Why Is My Upstairs So 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 common reasons an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to leak through the home’s attic or walls and contribute to heat loss, causing colder temperatures on the upper levels. It’s crucial 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 very important role in circulating conditioned air throughout different locations of the building. However, issues with the ductwork can contribute to the upstairs being colder than the main level. A common explanation for this is improper airflow balance. The ducts may not be the correct 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 level.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they are poorly located, it can reduce air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can lead to 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 examined by trusted professionals like the team at Taylor's Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more 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 home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system separates the residence into different 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 useful in situations where the upstairs of a multi-story home is very hot or really 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 effectively.

Why Is the Humidity So High Upstairs?
In addition to the upper story being hotter or colder than the rest of the house, another challenge in multi-floor homes is when the upper floors are more humid than the lower level.
A frequent reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can cause greater humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may permit 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 extra moisture in that area of a home.
To correct 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 prevent external moisture from entering the upstairs. Finding and repairing any leaks or plumbing issues is also imperative.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another useful tool to manage humidity in your home.
