Your entire home should be a sanctuary that’s warm and comfy in the cold months 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 rooms on ground level.
This could merely 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 differences between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these issues can be solved fairly quickly while others might require more extensive and costly fixes. Here, the specialists at Dial One Mears Air Conditioning & Heating Inc 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 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. Poor insulation in the attic or roof can make this worse by allowing heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not strong enough to cool the entire home, causing it to fight to cool the upstairs effectively.
To fix these issues, homeowners could add additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioning unit is the right size for the home, call an experienced HVAC company like Dial One Mears Air Conditioning & Heating Inc inspect the unit. A skilled professional also can help select a unit that's better suited for your home if you want air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that could result in 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 allows cold air to leak through the home’s attic or walls and contribute to heat loss, causing colder temperatures on higher floors. It’s essential to make sure your home has a thick, 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 rooms of the building. However, problems with the ductwork can cause the upstairs being colder than the main level. A typical explanation for this is improper airflow balance. The ducts may not be the right size or configuration, resulting in an uneven distribution of air between the floors. This can cause more warm air to be directed to the 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 story or they are not correctly located, it can restrict air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can lead to air loss, reducing 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 examined by trusted experts like the team at Dial One Mears Air Conditioning & Heating Inc to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help improve airflow and ensure a better 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 separates the residence 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 especially useful in situations where the upstairs of a multi-story home is quite hot or really cold while the main floor is comfortable. By implementing a zoning system, homeowners can control the temperature independently in each zone, enabling 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 upper floors are more humid than downstairs.
A frequent reason for excess upper floor humidity is weak ventilation on the upper floor, which can cause 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. In addition, if there are any leaks or plumbing issues on the upper floor, that can also lead to excessive moisture in that section of a home.
To fix humidity problems, homeowners can increase ventilation by getting fans or opening windows to promote airflow. Adding more 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 useful tool to reduce humidity on the upper and lower floors.
