Your entire residence should be a sanctuary that’s warm and cozy in the winter and cool and comfortable in the summer. However, owners of some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could simply 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 they 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 problems with your HVAC system. Some of these difficulties can be sorted out somewhat quickly while others might require more extensive and costly fixes. Here, the team at A2Z Air Inc will help you determine 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. For starters, 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 exacerbate this issue by permitting 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 struggle to cool the upstairs properly.
To tackle these issues, homeowners could add extra 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 A2Z Air Inc inspect the unit. A knowledgeable professional also can help select a unit that's better suited for your home if you need air conditioning installation or replacement.
Why Is My Upstairs Colder/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that could result in a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent reasons an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation permits cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s essential to make sure your home has a deep, 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 very important role in distributing conditioned air throughout different areas of the building. However, problems with the ductwork can contribute to the upstairs being colder than the main level. A common explanation for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, 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 higher floors.
Another factor with ductwork is the layout of the supply and return vents. If there are fewer vents on the upper floor or they are poorly located, it can limit 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 making the temperature difference more pronounced.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted HVAC pros like the team at A2Z Air Inc to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in additional vents or adjusting existing ones can help increase airflow and ensure a more consistent temperature balance between the upstairs and downstairs.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the rest of your house, an HVAC zoning system could be an effective solution.
An HVAC zoning system separates the home 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 especially helpful 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 control 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 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 inadequate ventilation on the upper floor, which can result in increased humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may permit warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also create extra moisture in that section of a home.
To manage humidity problems, homeowners can add more ventilation by installing 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. 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 worthwhile tool to control humidity on the upper and lower floors.
