Your entire home should be a sanctuary that’s warm and toasty in the cold months and cool and comfortable in the summer. However, residents in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the first floor.
This could simply be caused by the fact that most thermostats in a house are on the main 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 require more extensive and costly fixes. Here, the specialists at McFadden Heating & Cooling 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 natural for the second floor of a home to get hotter than the ground floor. Not enough 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 HVAC system is not powerful enough to cool the entire home, causing it to fight to cool the upstairs effectively.
To address these issues, homeowners could install more insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the air conditioning unit is the proper size for the home, call an experienced HVAC company like McFadden Heating & Cooling 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 extremely chilly upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it is supposed to 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, causing colder temperatures upstairs. It’s crucial to make sure your home has a thick, level layer of insulation in the attic and proper 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, troubles with the ductwork can result in the upstairs being colder than the lower floor. A typical explanation for this is improper airflow balance. The ducts may not be the correct size or design, 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 possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they aren't well positioned, it can limit air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, reducing 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 examined by experienced experts like the team at McFadden Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and installing 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 an effective solution.
An HVAC zoning system separates the home into distinctive 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 scenarios where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can control 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 upstairs is more humid than downstairs.
A frequent explanation for excess upper floor humidity is inadequate ventilation on the upper floor, which can produce greater humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may let warm, humid air from outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also create excessive moisture in that level of a home.
To fix humidity problems, homeowners can add more ventilation by installing 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 imperative.
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.
