Your entire residence should be a sanctuary that’s warm and toasty in the winter season 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 merely be caused by the fact that most thermostats in a house are on the first 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 discrepancies between the upstairs and downstairs could also be because of problems with your HVAC system. Some of these challenges can be resolved fairly quickly while others might require more extensive and costly fixes. Here, the professionals at Air-Right Energy Design 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. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Lack of 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 conditioner is not big enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.
To tackle these issues, homeowners could put in 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 ideal size for the home, call an experienced HVAC company like Air-Right Energy Design inspect the unit. A skilled professional also can help locate 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 very cold upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most common 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 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 fundamental role in distributing conditioned air throughout different areas of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the downstairs. A frequently reported cause for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, causing an uneven distribution of air between the floors. This can cause more warm air to go downstairs, which creates insufficient airflow—which is the heated air—on the upper level.
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 positioned, it can limit air circulation and cause inadequate heating or cooling. Also, 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 understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced experts like the team at Air-Right Energy Design to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help improve airflow and ensure a more even temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the rest of your home, 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 particularly useful in scenarios 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, enabling 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 downstairs.
A typical explanation for excess upper floor humidity is weak ventilation on the upper floor, which can produce greater 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. And, if there are any leaks or plumbing problems on the upper floor, that can also lead to unwanted moisture in that area of a home.
To address humidity problems, homeowners can increase ventilation by installing fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help protect against 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 helpful tool to manage humidity in the residence.
