Your entire home should be a refuge that’s warm and comfy in the cold months 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 just be because 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 problems with your HVAC system. Some of these issues can be fixed fairly quickly while others might call for more extensive and costly fixes. Here, the specialists at Tokay will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hot Upstairs?
The phenomenon of the upstairs of a two-story home getting hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s common for the second floor of a home to get hotter than the main floor. Insufficient 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 HVAC system is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.
To fix these issues, homeowners could add extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioner is the right size for the home, call an experienced HVAC company like Tokay inspect the unit. A skilled 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 Colder/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. It’s important 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 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 frequently reported reason for this is improper airflow balance. The ducts may not be the correct size or in the appropriate layout, creating an uneven distribution of air between the floors. This can cause more warm air to go downstairs, causing insufficient airflow—which is the heated air—on the upper story.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they aren't well positioned, it can limit air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, decreasing 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 Tokay to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help enhance 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 lower floors of your house, an HVAC zoning system could be an effective solution.
An HVAC zoning system divides the residence into different 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 very beneficial in scenarios where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By investing in a zoning system, homeowners can manage the temperature independently in each zone, making it possible for 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 problem in multi-floor homes is when the upstairs is more humid than the first floor.
A typical cause for excess upper floor humidity is weak ventilation on the upper floor, which can cause 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 outside infiltrate the upstairs rooms. In addition, 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 fix humidity problems, homeowners can add more ventilation by installing fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help prevent 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 manage humidity on the upper and lower floors.
