Your entire home should be a retreat that’s warm and toasty in the winter season and cool and comfortable in the summer. However, owners of some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could simply be caused by the fact that 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 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 problems with your HVAC system. Some of these challenges can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the team at Solar Air Inc. will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hotter Upstairs?
The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be attributed to several factors. For starters, heat rises, so it’s normal for the second floor of a home to get hotter than the ground floor. Lack of 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 big enough to cool the entire home, causing it to struggle to cool the upstairs properly.
To deal with these issues, homeowners could put in additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioner is the right size for the home, call an experienced HVAC company like Solar Air Inc. inspect the unit. A skilled professional also can help find a unit that's better suited for your home if you require air conditioning installation or replacement.
Why Is My Upstairs Colder/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures upstairs. It’s essential to make sure your home has a solid, 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 fundamental role in disseminating conditioned air throughout different areas of the building. However, issues with the ductwork can cause the upstairs being colder than the downstairs. A common explanation for this is improper airflow balance. The ducts may not be the right size or configuration, 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 placement of the supply and return vents. If there are fewer vents on the upper level or they are poorly positioned, it can restrict air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced experts like the team at Solar Air Inc. to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help increase airflow and ensure a more even temperature balance between the upstairs and downstairs.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the ground level of your house, an HVAC zoning system could be a great solution.
An HVAC zoning system breaks the household into different 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 very helpful in scenarios where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By investing in a zoning system, homeowners can control the temperature independently in each zone, making it possible for them to address specific hot or cold spots easily.

Why Is the Humidity So High Upstairs?
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 higher levels are more humid than downstairs.
A typical cause for excess upper floor humidity is weak ventilation on the upper floor, which can cause greater humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may permit warm, humid air from outside the house infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also cause excessive moisture in that section of a home.
To address 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 prevent external moisture from entering the upstairs. Finding 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 useful tool to manage humidity in the residence.
