Your entire residence should be a refuge that’s warm and cozy in the winter 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 first floor.
This could simply be due to the fact 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 they 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 solved relatively quickly while others might call for more extensive and costly fixes. Here, the professionals at Redhawk Heating & Air Conditioning 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 feeling hotter than the downstairs can be attributed to several factors. For starters, heat rises, so it’s normal 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 permitting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioner is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs properly.
To deal with these issues, homeowners could install more insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioner is the correct size for the home, call an experienced HVAC company like Redhawk Heating & Air Conditioning inspect the unit. A skilled professional also can help locate a unit that's better suited for your home if you need air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures on the upper levels. It’s important 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 critical role in circulating conditioned air throughout different locations of the building. However, issues with the ductwork can result in the upstairs being colder than the downstairs. A frequently reported cause for this is improper airflow balance. The ducts may not be the proper size or design, creating an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, causing insufficient airflow—which is the heated air—on the higher floors.
Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they aren't well placed, it can reduce air circulation and cause substandard heating or cooling. Also, leaks or gaps in the ductwork can lead to air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted professionals like the team at Redhawk Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help improve airflow and ensure a better 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 home, an HVAC zoning system could be an effective solution.
An HVAC zoning system separates the home into different 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 very useful in scenarios where the upstairs of a multi-story home is too hot or really cold while the main floor is comfortable. By investing in a zoning system, homeowners can manage the temperature independently in each zone, making it possible for 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 lower level.
A common explanation for excess upper floor humidity is weak 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 permit warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing issues on the upper floor, that can also create unwanted moisture in that level of a home.
To deal with humidity problems, homeowners can improve ventilation by using fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help stop 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 worthwhile tool to control humidity on the upper and lower floors.
