Every floor in your home should be a sanctuary that’s warm and comfy in the winter and cool and comfortable in the summer. However, families who live in some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could merely be due to the fact most thermostats in a house are on the first 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 trouble with your HVAC system. Some of these challenges can be fixed relatively quickly while others might call for more extensive and costly fixes. Here, the team at Refrigeration Systems Ltd. will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hotter Upstairs?
The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be traced 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. Not enough insulation in the attic or roof can exacerbate this issue by allowing 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 effectively.
To deal with these issues, homeowners could put in extra insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the AC is the right size for the home, call an experienced HVAC company like Refrigeration Systems Ltd. inspect the unit. A qualified professional also can help locate 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 very cold upstairs, that makes for 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 allows cold air to seep through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on the upper levels. It’s important 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 rooms of the building. However, problems with the ductwork can result in the upstairs being colder than the main level. A frequently reported reason 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 be directed to the downstairs, causing insufficient airflow—which is the heated air—on the upper level.
Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly placed, it can reduce air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by skilled experts like the team at Refrigeration Systems Ltd. to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional 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 residence, an HVAC zoning system could be an 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 helpful in instances where the upstairs of a multi-story home is very hot or too 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 easily.

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 upstairs is more humid than the lower level.
A typical reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in greater humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing problems on the upper floor, that can also cause excess moisture in that area of a home.
To manage humidity problems, homeowners can increase ventilation by installing fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help prevent external moisture from entering the upstairs. Finding 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 useful tool to control humidity on the upper and lower floors.
