Every floor in your home should be a sanctuary that’s warm and toasty in the winter season and cool and comfortable in the summer. However, families who live in some multi-level residences find the upper floor is stubbornly hotter or colder than the main floor.
This could simply be because most thermostats in a house are on the first floor, which is where people spend the most 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 discrepancies between the upstairs and downstairs could also be because of issues 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 team at J & J Air Conditioning will help you figure out 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 becoming hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s common for the second floor of a home to get hotter than the main floor. Not enough insulation in the attic or roof can worsen this problem by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioner is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs sufficiently.
To address these issues, homeowners could install more insulation in the attic and make sure their home has proper ventilation. If there’s concern the air conditioner is the ideal size for the home, call an experienced HVAC company like J & J Air Conditioning inspect the unit. A skilled professional also can help find a unit that's better suited for your home if you want 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 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 ought to are the insulation levels and the ductwork.
Inadequate insulation lets cold air to seep through the home’s attic or walls and contribute to heat loss, causing colder temperatures on the upper levels. It’s essential to make sure your home has a solid, 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 rooms of the building. However, issues with the ductwork can contribute to the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the right size or design, causing an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.
Another possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they are poorly placed, it can limit air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by experienced HVAC pros like the team at J & J 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 house, an HVAC zoning system could be a useful solution.
An HVAC zoning system separates the household into distinctive 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 effective in instances where the upstairs of a multi-story home is very hot or extremely 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 easily.

Why Is it So Humid 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 downstairs.
A common cause for excess upper floor humidity is weak ventilation on the upper floor, which can produce greater humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also create extra moisture in that area of a home.
To deal with humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Appropriate levels of 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 worthwhile tool to control humidity on the upper and lower floors.
