Your entire residence should be a retreat that’s warm and comfy in the winter and cool and comfortable in the summer. However, owners of some homes with multiple levels find the upper floor is stubbornly hotter or colder than the main floor.
This could just be caused by the fact that most thermostats in a house are on the main floor, which is where people spend the greatest amount of 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 variations between the upstairs and downstairs could also be caused by problems with your HVAC system. Some of these difficulties can be sorted out fairly quickly while others might require more extensive and costly fixes. Here, the professionals at Bain Heating & Air Conditioning will help you figure out 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 feeling hotter than the downstairs can be chalked up to several factors. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Lack of insulation in the attic or roof can exacerbate this issue by permitting 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 have difficulty cooling the upstairs properly.
To deal with these issues, homeowners could add extra insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the air conditioning unit is the ideal size for the home, call an experienced HVAC company like Bain Heating & Air Conditioning inspect the unit. A knowledgeable professional also can help find 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 very cold upstairs, that could result in 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 lets cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. It’s crucial to make sure your home has a deep, 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 critical role in circulating conditioned air throughout different areas of the building. However, problems with the ductwork can contribute to the upstairs being colder than the downstairs. A common cause for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, causing an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.
Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they are poorly positioned, it can limit air circulation and cause inferior heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, lowering the overall efficiency of the HVAC system and actually making the temperature difference worse.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by skilled professionals like the team at Bain Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help increase airflow and ensure a more consistent temperature balance between the upstairs and downstairs.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the ground level of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system separates the home into different 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 beneficial in instances where the upstairs of a multi-story home is very hot or extremely cold while the main floor is comfortable. By installing a zoning system, homeowners can manage the temperature independently in each zone, allowing them to address specific hot or cold spots effectively.

Why Is the Humidity So High 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 cause for excess upper floor humidity is poor ventilation on the upper floor, which can result in greater 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 outdoors infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also create unwanted moisture in that level of a home.
To deal with humidity problems, homeowners can improve 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. 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 useful tool to reduce humidity on the upper and lower floors.
