Every floor in your home should be a sanctuary that’s warm and toasty in the cold months and cool and comfortable in the summer. However, owners of some homes with multiple levels find the upper floor is stubbornly hotter or colder than the main floor.
This could merely be caused by the fact that most thermostats in a house are on the main 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 variations between the upstairs and downstairs could also be due to problems with your HVAC system. Some of these issues can be solved relatively quickly while others might require more extensive and costly fixes. Here, the specialists at Allstar Heating & Air Conditioning will help you figure out 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 feeling hotter than the downstairs can be traced to several factors. For starters, heat rises, so it’s common for the second floor of a home to get hotter than the ground floor. Insufficient insulation in the attic or roof can make this worse by permitting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not strong 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 question of whether the air conditioning unit is the ideal size for the home, call an experienced HVAC company like Allstar Heating & Air Conditioning inspect the unit. A qualified professional also can help find 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 extremely chilly upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most prevalent reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation lets cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures upstairs. It’s important to make sure your home has a thick, 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 circulating conditioned air throughout different locations of the building. However, issues with the ductwork can contribute to the upstairs being colder than the downstairs. A common cause for this is improper airflow balance. The ducts may not be the right size or configuration, causing an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.
Another possible issue with the ductwork is the layout 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 cause 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 examined by skilled experts like the team at Allstar Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help enhance 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 an effective solution.
An HVAC zoning system divides the household into distinctive 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 especially helpful in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By installing a zoning system, homeowners can control the temperature independently in each zone, allowing 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 problem in multi-floor homes is when the higher levels are more humid than the lower level.
A common reason for excess upper floor humidity is weak ventilation on the upper floor, which can result in increased humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may allow warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also create unwanted moisture in that section 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 protect against external moisture from entering the upstairs. Locating 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 helpful tool to manage humidity in your home.
