Your entire home should be a sanctuary that’s warm and toasty in the cold months 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 rooms on ground level.
This could simply be because most thermostats in a house are on the main floor, which is where people spend the most time—in the living room, kitchen, etc.—so it makes sense to 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 issues with your HVAC system. Some of these issues can be fixed somewhat quickly while others might call for more extensive and costly fixes. Here, the team at Woody's Sudden Service will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hotter Upstairs?
The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be traced to several factors. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the ground floor. Insufficient 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 conditioning is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.
To tackle these issues, homeowners could put in additional insulation in the attic and make sure their home has proper ventilation. If there’s concern the air conditioner is the ideal size for the home, call an experienced HVAC company like Woody's Sudden Service inspect the unit. A qualified 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 Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to filter through the home’s attic or walls and contribute to heat loss, causing colder temperatures on the upper levels. It’s essential to make sure your home has a solid, 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 critical role in circulating conditioned air throughout different areas of the building. However, problems with the ductwork can cause the upstairs being colder than the lower floor. A typical cause for this is improper airflow balance. The ducts may not be the right size or configuration, which results in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.
Another potential problem area in the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they are poorly placed, it can restrict air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, reducing 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 skilled HVAC pros like the team at Woody's Sudden Service to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help improve airflow and ensure a more consistent temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the lower floors of your house, an HVAC zoning system could be an effective solution.
An HVAC zoning system separates the household into different 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 particularly effective in scenarios where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By installing a zoning system, homeowners can control the temperature independently in each zone, making it possible for them to address specific hot or cold spots effortlessly.

Why Is it So Humid Upstairs?
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 downstairs.
A common explanation 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, inadequate insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems on the upper floor, that can also create unwanted moisture in that area of a home.
To deal with humidity problems, homeowners can add more ventilation by getting fans or opening windows to promote airflow. Adding more 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 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.
