Your entire residence should be a retreat that’s warm and toasty in the winter and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the main floor.
This could simply be because 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 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 due to trouble with your HVAC system. Some of these difficulties can be sorted out fairly quickly while others might necessitate more extensive and costly fixes. Here, the team at House of Heating Incorporated will help you solve 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 traced to several factors. For starters, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Lack of 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 have difficulty cooling the upstairs adequately.
To address these issues, homeowners could install additional insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the air conditioning unit is the ideal size for the home, call an experienced HVAC company like House of Heating Incorporated inspect the unit. A qualified 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 So Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most common causes of an upstairs not heating like it ought 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 important 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 very important role in disseminating conditioned air throughout different areas of the building. However, troubles with the ductwork can result in the upstairs being colder than the downstairs. A typical explanation for this is improper airflow balance. The ducts may not be the right size or design, causing an uneven distribution of air between the floors. This can cause more warm air to go downstairs, causing insufficient airflow—which is the heated air—on the upper story.
Another potential problem area in the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they aren't well installed, it can reduce air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted HVAC pros like the team at House of Heating Incorporated to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help improve airflow and ensure a better 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 house, an HVAC zoning system could be a great solution.
An HVAC zoning system divides the household into different 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 especially helpful in situations where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By implementing a zoning system, homeowners can control the temperature independently in each zone, allowing them to address specific hot or cold spots effectively.

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 upper floors are more humid than downstairs.
A common cause for excess upper floor humidity is poor ventilation on the upper floor, which can produce increased humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may permit warm, humid air from outside infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also cause extra moisture in that section of a home.
To manage humidity problems, homeowners can improve ventilation by installing fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help stop 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 valuable tool to reduce humidity on the upper and lower floors.
