Your entire home should be a retreat that’s warm and cozy in the winter season and cool and comfortable in the summer. However, families who live in some two-story homes find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could just be due to the fact most thermostats in a house are on the first floor, which is where people spend the the majority of time—in the living room, kitchen, etc.—so as a result they tend 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 issues with your HVAC system. Some of these challenges can be solved somewhat quickly while others might require more extensive and costly fixes. Here, the specialists at Tokay 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 traced to several factors. For starters, heat rises, so it’s normal 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 air conditioner is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.
To address these issues, homeowners could add more insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the air conditioner is the correct size for the home, call an experienced HVAC company like Tokay inspect the unit. A skilled professional also can help find a unit that's better suited for your home if you need air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most common causes of an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to seep through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. 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 critical role in distributing conditioned air throughout different rooms of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the lower floor. A frequently reported cause for this is improper airflow balance. The ducts may not be the right size or design, causing an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, leaving insufficient airflow—which is the heated air—on the upper story.
Another potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they are not correctly located, it can reduce air circulation and cause substandard heating or cooling. Also, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To figure 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 increase airflow and ensure a more even 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 a useful solution.
An HVAC zoning system separates the residence into distinct 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 especially useful in instances where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By investing in a zoning system, homeowners can manage the temperature independently in each zone, allowing 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 upper floors are more humid than the first floor.
A frequent cause for excess upper floor humidity is poor ventilation on the upper floor, which can produce increased humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may allow warm, humid air from outside infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing concerns on the upper floor, that can also lead to unwanted moisture in that level of a home.
To manage humidity problems, homeowners can increase ventilation by getting 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. Identifying 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 valuable tool to control humidity on the upper and lower floors.
