Every floor in your home should be a refuge that’s warm and toasty in the winter 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 rooms on ground level.
This could merely be due to the fact 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 differences between the upstairs and downstairs could also be caused by trouble with your HVAC system. Some of these issues can be resolved relatively quickly while others might necessitate more extensive and costly fixes. Here, the specialists at J & J Air Conditioning 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 traced to several factors. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the main floor. Not enough 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 air conditioner is not big enough to cool the entire home, causing it to fight to cool the upstairs properly.
To address these issues, homeowners could add additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the AC is the correct size for the home, call an experienced HVAC company like J & J Air Conditioning inspect the unit. A qualified professional also can help select a unit that's better suited for your home if you require 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 makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to filter 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 adequate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a very important role in disseminating conditioned air throughout different areas 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 in the appropriate layout, causing an uneven distribution of air between the floors. This can cause more warm air to go downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.
Another possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they aren't well located, it can limit air circulation and cause substandard heating or cooling. Also, leaks or gaps in the ductwork can allow 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 inspected by skilled professionals like the team at J & J Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help enhance airflow and ensure a better 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 home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system breaks the home 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 scenarios where the upstairs of a multi-story home is very hot or extremely cold while the main floor is comfortable. By implementing a zoning system, homeowners can regulate the temperature independently in each zone, enabling them to address specific hot or cold spots easily.

Why Is it So Humid Upstairs?
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 downstairs.
A typical explanation for excess upper floor humidity is poor ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may permit warm, humid air from outside infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also lead to extra moisture in that level of a home.
To manage humidity problems, homeowners can increase ventilation by using fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Locating and repairing any leaks or plumbing issues is also critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another helpful tool to manage humidity in your home.
