Your entire home should be a refuge that’s warm and cozy in the winter season 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 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 most time—in the living room, kitchen, etc.—so they set the temperature according to how it feels on the first floor.
However, temperature variations between the upstairs and downstairs could also be due to problems with your HVAC system. Some of these issues can be fixed relatively quickly while others might call for more extensive and costly fixes. Here, the team at Clean Air HVAC 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 natural for the second floor of a home to get hotter than the main floor. Not enough insulation in the attic or roof can exacerbate this issue by allowing heat transfer from the roof into the upstairs rooms.
Another common reason is that the HVAC system is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs effectively.
To address these issues, homeowners could add additional insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the AC is the correct size for the home, call an experienced HVAC company like Clean Air HVAC inspect the unit. A qualified professional also can help locate 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 very cold upstairs, that makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it should 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, creating colder temperatures on higher floors. It’s essential to make sure your home has a thick, level layer of insulation in the attic and proper 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 cause the upstairs being colder than the downstairs. A common cause 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 flow downstairs, which creates insufficient airflow—which is the heated air—on the upper story.
Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly located, it can reduce air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can allow 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 inspected by experienced HVAC pros like the team at Clean Air HVAC to identify any imbalances, leaks or inadequacies. Sealing leaks and installing additional vents or adjusting existing ones can help improve airflow and ensure a more consistent 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 rest of your residence, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system breaks the household into distinctive 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 effective in instances where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By implementing 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 the lower level.
A typical reason for excess upper floor humidity is poor 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 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 lead to extra moisture in that level of a home.
To address humidity problems, homeowners can improve ventilation by getting 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 extremely important.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another worthwhile tool to reduce humidity in the residence.
