Every floor in your home should be a retreat that’s warm and cozy in the winter season and cool and comfortable in the summer. However, families who live in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the first 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 the majority of 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 discrepancies between the upstairs and downstairs could also be caused by problems with your HVAC system. Some of these difficulties can be fixed somewhat quickly while others might require more extensive and costly fixes. Here, the specialists at Custom Air Systems 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 becoming hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Poor 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 conditioning is not big enough to cool the entire home, causing it to fight to cool the upstairs effectively.
To fix these issues, homeowners could put in additional insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the air conditioner is the correct size for the home, call an experienced HVAC company like Custom Air Systems inspect the unit. A knowledgeable 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 extremely chilly upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it should 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 on higher floors. It’s essential to make sure your home has a thick, 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 very important role in disseminating conditioned air throughout different areas of the building. However, problems with the ductwork can cause the upstairs being colder than the main level. A frequently reported cause for this is improper airflow balance. The ducts may not be the proper size or design, which results in an uneven distribution of air between the floors. This can cause more warm air to go downstairs, leaving insufficient airflow—which is the heated air—on the upper level.
Another factor with ductwork is the layout of the supply and return vents. If there are fewer vents on the upper story 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 lead to 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 inspected by trusted professionals like the team at Custom Air Systems to identify any imbalances, leaks or inadequacies. Sealing leaks and installing additional 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 an effective solution.
An HVAC zoning system divides the residence into distinctive 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 especially beneficial in scenarios where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By investing in a zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots effectively.

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 upstairs is more humid than the first floor.
A frequent reason for excess upper floor humidity is poor ventilation on the upper floor, which can cause greater humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may let warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also cause unwanted moisture in that area of a home.
To deal with 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 protect against external moisture from entering the upstairs. Finding 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 valuable tool to control humidity in the residence.
