Every floor in your home should be a retreat that’s warm and cozy in the winter and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the rooms on ground level.
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 the majority of 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 caused by problems with your HVAC system. Some of these issues can be solved somewhat quickly while others might require more extensive and costly fixes. Here, the specialists at GV Heating & Air 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 attributed to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Not enough 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 have difficulty cooling the upstairs properly.
To tackle these issues, homeowners could add extra insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the air conditioning unit is the proper size for the home, call an experienced HVAC company like GV Heating & Air inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you are considering 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 can cause a frosty 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 allows cold air to filter through the home’s attic or walls and contribute to heat loss, causing colder temperatures on higher floors. 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 fundamental role in distributing conditioned air throughout different rooms of the building. However, troubles with the ductwork can cause the upstairs being colder than the main level. A common reason for this is improper airflow balance. The ducts may not be the right size or configuration, creating 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 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 level or they are poorly placed, it can restrict air circulation and cause inferior heating or cooling. Additionally, 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 determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted HVAC pros like the team at GV Heating & Air to identify any imbalances, leaks or inadequacies. Sealing leaks and installing 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 lower floors of your residence, an HVAC zoning system could be a great solution.
An HVAC zoning system divides the home into distinct 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 particularly useful in instances where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By implementing a zoning system, homeowners can control the temperature independently in each zone, allowing 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 challenge in multi-floor homes is when the upstairs is more humid than the first floor.
A typical explanation for excess upper floor humidity is inadequate 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 concerns on the upper floor, that can also lead to excess moisture in that area of a home.
To fix humidity problems, homeowners can improve ventilation by using 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. Locating 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 valuable tool to control humidity in your home.
