Every floor in your home should be a retreat that’s warm and comfy in the cold months 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 first floor.
This could merely be because 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 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 challenges can be fixed relatively quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Willco Air Conditioning, Refrigeration & Heating Inc. will help you determine 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. For starters, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Poor insulation in the attic or roof can make this worse 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 struggle to cool the upstairs properly.
To address these issues, homeowners could install additional 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 Willco Air Conditioning, Refrigeration & Heating Inc. 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 a very chilly night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation enables cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures on higher floors. It’s crucial to make sure your home has a solid, 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 very important role in circulating conditioned air throughout different locations of the building. However, problems with the ductwork can cause the upstairs being colder than the lower floor. A typical 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 go downstairs, leaving insufficient airflow—which is the heated air—on the upper level.
Another possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they are not correctly positioned, it can restrict air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, decreasing the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by skilled experts like the team at Willco Air Conditioning, Refrigeration & Heating Inc. to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help increase 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 house, an HVAC zoning system could be a useful solution.
An HVAC zoning system breaks the residence 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 helpful in situations where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By implementing 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 issue in multi-floor homes is when the higher levels are more humid than the first floor.
A common reason for excess upper floor humidity is poor ventilation on the upper floor, which can produce greater humidity levels. As is often the case with temperature differences between floors, inadequate 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 problems on the upper floor, that can also lead to extra moisture in that level of a home.
To manage humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Appropriate levels of 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 helpful tool to reduce humidity in your home.
