Your entire home should be a sanctuary that’s warm and comfy in the winter 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 merely be due to the fact most thermostats in a house are on the ground floor, which is where people spend the greatest amount of 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 caused by trouble with your HVAC system. Some of these challenges can be sorted out relatively quickly while others might call for more extensive and costly fixes. Here, the specialists at Tri County Climate Control LLC 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. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the ground floor. Poor 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 conditioning is not strong enough to cool the entire home, causing it to fight to cool the upstairs properly.
To deal with these issues, homeowners could put in extra insulation in the attic and make sure their home has adequate ventilation. If there’s concern the AC is the correct size for the home, call an experienced HVAC company like Tri County Climate Control LLC inspect the unit. A knowledgeable 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 extremely chilly 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 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 important 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, issues with the ductwork can result in 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 in the appropriate layout, creating an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, leaving insufficient airflow—which is the heated air—on the upper story.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly installed, it can restrict air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced HVAC pros like the team at Tri County Climate Control LLC to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help improve airflow and ensure a more consistent 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 home, an HVAC zoning system could be a great solution.
An HVAC zoning system separates the household into different 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 helpful in scenarios where the upstairs of a multi-story home is too hot or really cold while the main floor is comfortable. By installing a zoning system, homeowners can manage the temperature independently in each zone, making it possible for 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 upper floors are more humid than the lower level.
A common reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in increased humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may allow warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also create unwanted moisture in that area of a home.
To correct humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Adding more insulation in the attic and better sealing the attic and walls can help prevent 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 helpful tool to reduce humidity on the upper and lower floors.
