Your entire home should be a retreat that’s warm and cozy in the cold months 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 rooms on ground level.
This could just 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 they 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 problems with your HVAC system. Some of these challenges can be solved fairly quickly while others might require more extensive and costly fixes. Here, the professionals at Bell Mechanical Services will help you determine 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 getting hotter than the downstairs can be traced to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Not enough 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 conditioning is not big enough to cool the entire home, causing it to struggle to cool the upstairs properly.
To fix these issues, homeowners could put in more insulation in the attic and make sure their home has adequate ventilation. If there’s concern the air conditioner is the proper size for the home, call an experienced HVAC company like Bell Mechanical Services inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you want 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 could result in a very chilly night for anyone whose bedrooms are on the upper floor. The most common causes of an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to filter through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. 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 very important role in disseminating conditioned air throughout different locations of the building. However, problems with the ductwork can result in the upstairs being colder than the lower floor. A common explanation for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, creating an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, which creates insufficient airflow—which is the heated air—on the upper story.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they are poorly installed, it can restrict air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, decreasing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced HVAC pros like the team at Bell Mechanical Services to identify any imbalances, leaks or inadequacies. Sealing leaks and adding 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 a great solution.
An HVAC zoning system breaks the home into distinctive 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 particularly helpful in scenarios 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, enabling 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 higher levels are more humid than the lower level.
A frequent reason for excess upper floor humidity is poor ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may permit 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 lead to excessive moisture in that level of a home.
To correct humidity problems, homeowners can add more 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 prevent external moisture from entering the upstairs. Locating 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 helpful tool to reduce humidity on the upper and lower floors.
