Your entire residence should be a sanctuary that’s warm and cozy in the cold months 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 main floor.
This could merely be because most thermostats in a house are on the first floor, which is where people spend the greatest amount of 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 variations between the upstairs and downstairs could also be due to problems with your HVAC system. Some of these challenges can be fixed fairly quickly while others might call for more extensive and costly fixes. Here, the team at Bishop’s HVAC will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hot Upstairs?
The phenomenon of the upstairs of a two-story home getting hotter than the downstairs can be attributed to several factors. For starters, heat rises, so it’s common for the second floor of a home to get hotter than the first 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 HVAC system is not strong enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To deal with these issues, homeowners could add additional insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the air conditioner is the right size for the home, call an experienced HVAC company like Bishop’s HVAC inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you are considering air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to leak through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s important 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 disseminating conditioned air throughout different rooms of the building. However, issues with the ductwork can contribute to the upstairs being colder than the main level. A typical reason 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 go downstairs, which creates 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 floor or they are not correctly installed, it can limit air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can cause 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 examined by skilled professionals like the team at Bishop’s HVAC to identify any imbalances, leaks or inadequacies. Sealing leaks and adding 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 lower floors of your home, an HVAC zoning system could be an effective solution.
An HVAC zoning system breaks 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 particularly useful in situations where the upstairs of a multi-story home is quite hot or too 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 upper floors are more humid than downstairs.
A frequent reason for excess upper floor humidity is poor ventilation on the upper floor, which can result in greater humidity levels. As is often the case with temperature differences between floors, insufficient 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 concerns on the upper floor, that can also lead to excess moisture in that level of a home.
To deal with humidity problems, homeowners can improve 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 valuable tool to reduce humidity on the upper and lower floors.
