Your entire home should be a retreat that’s warm and comfy in the winter and cool and comfortable in the summer. However, residents in some two-story homes find the upper floor is stubbornly hotter or colder than the main floor.
This could just be because 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 it makes sense to set the temperature according to how it feels on the first floor.
However, temperature differences between the upstairs and downstairs could also be caused by trouble with your HVAC system. Some of these difficulties can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the team at McFadden Heating & Cooling will help you figure out 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 getting hotter than the downstairs can be chalked up to several factors. For starters, heat rises, so it’s common for the second floor of a home to get hotter than the first floor. Lack of 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 strong enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To address these issues, homeowners could install extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioning unit is the right size for the home, call an experienced HVAC company like McFadden Heating & Cooling inspect the unit. A skilled professional also can help select a unit that's better suited for your home if you want 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 could result in an ice-cold 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 permits cold air to seep through the home’s attic or walls and contribute to heat loss, causing colder temperatures on higher floors. It’s crucial 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 areas of the building. However, issues with the ductwork can contribute to the upstairs being colder than the downstairs. A frequently reported cause for this is improper airflow balance. The ducts may not be the correct size or design, creating an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing insufficient airflow—which is the heated air—on the upper story.
Another possible issue with the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper floor or they are poorly placed, it can restrict air circulation and cause inferior heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted 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 increase airflow and ensure a more even temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the rest of your house, an HVAC zoning system could be a great solution.
An HVAC zoning system breaks 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 very useful in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By installing a zoning system, homeowners can control the temperature independently in each zone, enabling them to address specific hot or cold spots effectively.

Why Is My Upstairs So Humid?
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 upper floors are more humid than the first floor.
A common explanation 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, insufficient insulation or sealing in the attic or walls may allow warm, humid air from outside the house infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing concerns on the upper floor, that can also cause excessive moisture in that section of a home.
To manage 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 stop 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 useful tool to reduce humidity on the upper and lower floors.
