Every floor in your home should be a sanctuary that’s warm and comfy in the winter season 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 first floor.
This could merely be caused by the fact that most thermostats in a house are on the main floor, which is where people spend the the majority of time—in the living room, kitchen, etc.—so they set the temperature according to how it feels on the first floor.
However, temperature differences between the upstairs and downstairs could also be caused by trouble with your HVAC system. Some of these issues can be sorted out fairly quickly while others might call for more extensive and costly fixes. Here, the team at May's Heating & Air 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 getting hotter than the downstairs can be chalked up to several factors. For starters, 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 letting 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 struggle to cool the upstairs effectively.
To deal with these issues, homeowners could install more insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioner is the proper size for the home, call an experienced HVAC company like May's Heating & Air inspect the unit. A skilled professional also can help locate a unit that's better suited for your home if you require air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures on the upper levels. It’s essential to make sure your home has a thick, 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 disseminating 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 typical reason for this is improper airflow balance. The ducts may not be the correct size or design, resulting in 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 higher floors.
Another potential problem area in the ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they are not correctly positioned, it can limit air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can lead to air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by skilled professionals like the team at May's Heating & Air to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new 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 home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system divides the household into distinctive zones, which each have their own thermostat and damper system so the homeowner can customize the heating or cooling of each zone.
This system can be very useful 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, 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 challenge in multi-floor homes is when the higher levels are more humid than the first floor.
A typical explanation for excess upper floor humidity is poor 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 the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also lead to extra moisture in that section of a home.
To deal with humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Locating 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 manage humidity in your home.
