Your entire home should be a retreat that’s warm and cozy in the cold months and cool and comfortable in the summer. However, families who live in some two-story homes find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could merely 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 as a result they tend to set the temperature according to how it feels on the first floor.
However, temperature variations between the upstairs and downstairs could also be caused by issues with your HVAC system. Some of these difficulties can be solved relatively quickly while others might necessitate more extensive and costly fixes. Here, the specialists at B&D Air Conditioning 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 ground floor. Not enough 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 powerful enough to cool the entire home, causing it to fight 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 ideal size for the home, call an experienced HVAC company like B&D Air Conditioning inspect the unit. A knowledgeable 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 Always Cold/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation allows 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 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 critical role in circulating conditioned air throughout different areas of the building. However, troubles with the ductwork can cause the upstairs being colder than the lower floor. A typical reason for this is improper airflow balance. The ducts may not be the right size or design, creating an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they are poorly located, it can limit air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, decreasing the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by experienced professionals like the team at B&D Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help enhance airflow and ensure a better temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the ground level of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system breaks the residence 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 beneficial in situations where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By implementing a zoning system, homeowners can regulate 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 problem in multi-floor homes is when the upper floors are more humid than downstairs.
A typical explanation for excess upper floor humidity is inadequate ventilation on the upper floor, which can produce greater humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may allow 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 excessive moisture in that area of a home.
To manage humidity problems, homeowners can add more 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 critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another worthwhile tool to control humidity on the upper and lower floors.
