Your entire residence should be a refuge that’s warm and comfy 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 first floor.
This could just be due to the fact 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 it makes sense 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 trouble 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 team at Solar Air Inc. 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 becoming hotter than the downstairs can be chalked up 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. Lack of 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 strong enough to cool the entire home, causing it to have difficulty cooling the upstairs effectively.
To tackle these issues, homeowners could put in extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the air conditioner is the correct size for the home, call an experienced HVAC company like Solar Air Inc. inspect the unit. A knowledgeable professional also can help locate a unit that's better suited for your home if you require 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 makes for a frosty night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation lets cold air to seep through the home’s attic or walls and contribute to heat loss, causing colder temperatures on the upper levels. It’s essential 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 circulating conditioned air throughout different rooms of the building. However, issues with the ductwork can cause the upstairs being colder than the downstairs. A typical reason for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, creating an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, causing insufficient airflow—which is the heated air—on the upper level.
Another potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper story or they are not correctly positioned, it can restrict air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, lowering 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 Solar Air Inc. 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 consistent 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 ground level of your home, an HVAC zoning system could be a great solution.
An HVAC zoning system divides the residence into distinctive zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.
This system can be particularly helpful in situations where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By implementing a zoning system, homeowners can regulate the temperature independently in each zone, making it possible for 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 challenge in multi-floor homes is when the higher levels are more humid than the lower level.
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 allow warm, humid air from outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also create excess moisture in that level of a home.
To correct humidity problems, homeowners can improve ventilation by using 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. 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 valuable tool to control humidity in your home.
