Every floor in your home should be a refuge that’s warm and toasty in the winter season and cool and comfortable in the summer. However, owners of some two-story homes find the upper floor is stubbornly hotter or colder than the main 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 problems with your HVAC system. Some of these challenges can be sorted out somewhat quickly while others might require more extensive and costly fixes. Here, the specialists at Covington Air Systems will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hot Upstairs?
The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be chalked up to several factors. First, 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 exacerbate this issue 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 effectively.
To fix 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 AC is the ideal size for the home, call an experienced HVAC company like Covington Air Systems inspect the unit. A knowledgeable professional also can help select a unit that's better suited for your home if you are considering air conditioning installation or replacement.
Why Is My Upstairs Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most common causes of an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation permits cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on the upper levels. 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 disseminating conditioned air throughout different areas of the building. However, troubles with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the right size or design, 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 upper story.
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 limit air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can lead to air loss, lowering the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted experts like the team at Covington Air Systems to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help improve airflow and ensure a more consistent temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the lower floors of your house, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system separates the household 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 especially effective in instances where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By installing 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 inadequate ventilation on the upper floor, which can cause higher humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may permit warm, humid air from outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also lead to extra 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. 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 imperative.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another worthwhile tool to manage humidity on the upper and lower floors.
