Your entire residence should be a refuge that’s warm and toasty in the winter and cool and comfortable in the summer. However, residents in some two-story homes find the upper floor is stubbornly hotter or colder than the main floor.
This could just be because 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 they set the temperature according to how it feels on the first floor.
However, temperature variations between the upstairs and downstairs could also be caused by issues with your HVAC system. Some of these issues can be resolved somewhat quickly while others might necessitate more extensive and costly fixes. Here, the team at Fleming Heating & Air Conditioning Inc 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 chalked up to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the main floor. Insufficient 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 HVAC system is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs effectively.
To tackle these issues, homeowners could install more insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the air conditioner is the proper size for the home, call an experienced HVAC company like Fleming Heating & Air Conditioning Inc inspect the unit. A skilled 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 freezing upstairs, that can cause a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it is supposed to 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, creating colder temperatures on the upper levels. It’s essential to make sure your home has a thick, 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 very important role in circulating conditioned air throughout different rooms of the building. However, problems with the ductwork can result in the upstairs being colder than the downstairs. A common cause for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, causing an uneven distribution of air between the floors. This can cause more warm air to go downstairs, causing insufficient airflow—which is the heated air—on the upper level.
Another potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper story or they are poorly positioned, it can restrict air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, lowering 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 trusted experts like the team at Fleming Heating & Air Conditioning Inc to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in more vents or adjusting existing ones can help increase 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 residence, an HVAC zoning system could be an effective solution.
An HVAC zoning system breaks the household into different 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 especially helpful 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 regulate 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 challenge in multi-floor homes is when the upper floors are more humid than downstairs.
A common cause for excess upper floor humidity is poor ventilation on the upper floor, which can produce greater humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may allow warm, humid air from outside the house infiltrate the upstairs rooms. And, if there are any leaks or plumbing problems on the upper floor, that can also create extra moisture in that level of a home.
To address 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 prevent external moisture from entering the upstairs. Identifying 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 manage humidity in the residence.
