Your entire residence should be a refuge that’s warm and toasty in the winter season and cool and comfortable in the summer. However, families who live in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the main 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 greatest amount 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 issues with your HVAC system. Some of these issues can be fixed fairly quickly while others might require more extensive and costly fixes. Here, the specialists at AZ Air Conditioning and Heating 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 becoming hotter than the downstairs can be attributed to several factors. For starters, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Lack of insulation in the attic or roof can worsen this problem by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the HVAC system is not big enough to cool the entire home, causing it to fight to cool the upstairs effectively.
To tackle these issues, homeowners could install more insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the air conditioner is the correct size for the home, call an experienced HVAC company like AZ Air Conditioning and Heating inspect the unit. A knowledgeable 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 Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that could result in a very chilly night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it is supposed 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, 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 appropriate 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, issues with the ductwork can result in the upstairs being colder than the downstairs. A common reason for this is improper airflow balance. The ducts may not be the proper size or design, causing an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, which creates insufficient airflow—which is the heated air—on the upper story.
Another possible issue with the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they aren't well installed, 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 find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by experienced professionals like the team at AZ Air Conditioning and Heating to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help enhance 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 highly effective solution.
An HVAC zoning system separates the residence 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 beneficial in scenarios where the upstairs of a multi-story home is too hot or extremely 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 effectively.

Why Is the Humidity So High Upstairs?
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 lower level.
A frequent cause for excess upper floor humidity is weak ventilation on the upper floor, which can cause 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 outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also cause extra moisture in that level of a home.
To fix humidity problems, homeowners can improve 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 stop external moisture from entering the upstairs. Identifying 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 valuable tool to control humidity on the upper and lower floors.
