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, families who live in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the first floor.
This could merely be due to the fact 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 variations between the upstairs and downstairs could also be caused by problems with your HVAC system. Some of these challenges can be sorted out fairly quickly while others might necessitate more extensive and costly fixes. Here, the team at Alpine Summit Heating & Cooling 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 getting hotter than the downstairs can be traced to several factors. For starters, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Lack of insulation in the attic or roof can make this worse by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs sufficiently.
To deal with these issues, homeowners could add additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the AC is the correct size for the home, call an experienced HVAC company like Alpine Summit Heating & Cooling inspect the unit. A knowledgeable professional also can help locate a unit that's better suited for your home if you require 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 could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent causes of 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, creating colder temperatures on higher floors. It’s essential to make sure your home has a solid, level layer of insulation in the attic and adequate 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 areas of the building. However, troubles with the ductwork can cause the upstairs being colder than the lower floor. A typical explanation for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, resulting in an uneven distribution of air between the floors. This can cause more warm air to be directed to the 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 located, it can reduce air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can lead to air loss, reducing 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 inspected by experienced experts like the team at Alpine Summit Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new 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 ground level of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system separates the home into distinct 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 very useful in scenarios where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can regulate the temperature independently in each zone, enabling them to address specific hot or cold spots effortlessly.

Why Is My Upstairs So Humid?
In addition to the upper story being hotter or colder than the rest of the house, another problem 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 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 outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also cause extra moisture in that level of a home.
To deal with humidity problems, homeowners can increase ventilation by getting fans or opening windows to promote airflow. Adding more 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 useful tool to reduce humidity in the residence.
