Every floor in your home should be a retreat that’s warm and toasty in the cold months 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 first 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 the majority 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 because of issues with your HVAC system. Some of these issues can be sorted out somewhat quickly while others might call for more extensive and costly fixes. Here, the professionals at Comfort Zone, LLC 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. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the ground floor. Insufficient insulation in the attic or roof can worsen this problem by allowing 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 properly.
To tackle these issues, homeowners could put in extra insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the AC is the correct size for the home, call an experienced HVAC company like Comfort Zone, LLC inspect the unit. A qualified professional also can help select 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 very cold upstairs, that can cause an ice-cold 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 seep through the home’s attic or walls and contribute to heat loss, creating 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 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, issues with the ductwork can contribute to the upstairs being colder than the main level. A typical cause for this is improper airflow balance. The ducts may not be the correct size or configuration, resulting in an uneven distribution of air between the floors. This can cause more warm air to go downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.
Another potential problem area in the ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly positioned, it can limit air circulation and cause inadequate heating or cooling. Also, 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 determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted experts like the team at Comfort Zone, LLC 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 more even 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 rest of your home, an HVAC zoning system could be a great solution.
An HVAC zoning system breaks the household into distinct 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 situations where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can control 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 issue in multi-floor homes is when the upper floors are more humid than the lower level.
A typical explanation for excess upper floor humidity is poor ventilation on the upper floor, which can cause increased 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 cause unwanted moisture in that level of a home.
To manage 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 stop 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 reduce humidity in the residence.
