Every floor in your home should be a sanctuary that’s warm and toasty in the winter season 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 first floor.
This could merely be because most thermostats in a house are on the ground floor, which is where people spend the most time—in the living room, kitchen, etc.—so as a result they tend to set the temperature according to how it feels on the first floor.
However, temperature discrepancies between the upstairs and downstairs could also be because of issues with your HVAC system. Some of these challenges can be sorted out relatively quickly while others might necessitate more extensive and costly fixes. Here, the specialists at Miller 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 feeling hotter than the downstairs can be traced to several factors. For starters, heat rises, so it’s natural for the second floor of a home to get hotter than the main floor. Insufficient 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 HVAC system is not strong enough to cool the entire home, causing it to struggle to cool the upstairs adequately.
To deal with these issues, homeowners could add extra insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the air conditioning unit is the ideal size for the home, call an experienced HVAC company like Miller Climate Control LLC inspect the unit. A qualified professional also can help find a unit that's better suited for your home if you are considering 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 could result in a frosty night for anyone whose bedrooms are on the upper floor. The most common explanations for an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation lets cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on the upper levels. It’s crucial to make sure your home has a solid, 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 disseminating conditioned air throughout different locations of the building. However, troubles with the ductwork can result in the upstairs being colder than the main level. A typical cause for this is improper airflow balance. The ducts may not be the proper size or configuration, which results in 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 factor with ductwork is the layout of the supply and return vents. If there are fewer vents on the upper story or they aren't well placed, it can limit air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can lead to air loss, decreasing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced experts like the team at Miller Climate Control LLC 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 rest of your residence, 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 modify the heating or cooling of each zone.
This system can be especially helpful in scenarios where the upstairs of a multi-story home is very hot or really 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 easily.

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 downstairs.
A frequent cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can produce higher humidity levels. As is often the case with temperature differences between floors, inadequate 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 excessive moisture in that area of a home.
To address humidity problems, homeowners can add more ventilation by getting 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. Locating 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 valuable tool to control humidity in the residence.
