Every floor in your home should be a retreat that’s warm and comfy in the winter and cool and comfortable in the summer. However, families who live in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the main floor.
This could just be caused by the fact that 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 they set the temperature according to how it feels on the first floor.
However, temperature variations between the upstairs and downstairs could also be because of problems with your HVAC system. Some of these issues can be sorted out fairly quickly while others might call for more extensive and costly fixes. Here, the team at Myers Furnace Company will help you figure out 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 chalked up to several factors. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Lack of 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 big enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To fix these issues, homeowners could put in more insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioning unit is the proper size for the home, call an experienced HVAC company like Myers Furnace Company inspect the unit. A qualified professional also can help select 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 makes for a frosty night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation allows cold air to filter through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s important to make sure your home has a solid, level layer of insulation in the attic and appropriate 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 rooms of the building. However, issues with the ductwork can contribute to the upstairs being colder than the main level. A typical reason for this is improper airflow balance. The ducts may not be the proper size or design, causing 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 story.
Another possible issue with the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper floor or they aren't well installed, it can restrict air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can cause air loss, decreasing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced HVAC pros like the team at Myers Furnace Company to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help enhance 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 ground level of your house, an HVAC zoning system could be a great solution.
An HVAC zoning system breaks the residence into different 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 especially effective in instances where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By investing in a zoning system, homeowners can control the temperature independently in each zone, allowing 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 issue in multi-floor homes is when the higher levels are more humid than downstairs.
A frequent explanation for excess upper floor humidity is weak ventilation on the upper floor, which can cause higher 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 infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also lead to excess moisture in that level of a home.
To deal with humidity problems, homeowners can increase ventilation by installing fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Identifying 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 helpful tool to reduce humidity in the residence.
