Your entire residence should be a retreat that’s warm and toasty in the winter season and cool and comfortable in the summer. However, residents in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the main floor.
This could simply be caused by the fact that most thermostats in a house are on the first floor, which is where people spend the the majority 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 caused by problems with your HVAC system. Some of these challenges can be resolved relatively quickly while others might necessitate more extensive and costly fixes. Here, the specialists at Bell Air Conditioning Inc 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 traced to several factors. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the ground floor. Poor insulation in the attic or roof can make this worse by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioner is not big enough to cool the entire home, causing it to fight to cool the upstairs effectively.
To address these issues, homeowners could add additional insulation in the attic and make sure their home has adequate ventilation. If there’s concern the air conditioner is the correct size for the home, call an experienced HVAC company like Bell Air Conditioning Inc inspect the unit. A qualified professional also can help select a unit that's better suited for your home if you require air conditioning installation or replacement.
Why Is My Upstairs Colder/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that could result in a frosty 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 enables cold air to seep through the home’s attic or walls and contribute to heat loss, creating colder temperatures on the upper levels. It’s important to make sure your home has a thick, level layer of insulation in the attic and appropriate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a fundamental role in distributing conditioned air throughout different locations of the building. However, problems with the ductwork can result in the upstairs being colder than the downstairs. A typical reason for this is improper airflow balance. The ducts may not be the proper size or configuration, causing an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing insufficient airflow—which is the heated air—on the higher floors.
Another possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper story or they are not correctly positioned, it can reduce air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by skilled experts like the team at Bell Air Conditioning Inc to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in additional vents or adjusting existing ones can help increase airflow and ensure a better temperature balance between the upstairs and downstairs.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the rest of your residence, an HVAC zoning system could be an effective solution.
An HVAC zoning system breaks the household into distinct 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 especially useful in scenarios where the upstairs of a multi-story home is quite hot or really cold while the main floor is comfortable. By installing a zoning system, homeowners can regulate the temperature independently in each zone, making it possible for them to address specific hot or cold spots effectively.

Why Is it So Humid Upstairs?
In addition to the upper story being hotter or colder than the rest of the house, another issue in multi-floor homes is when the higher levels are more humid than the lower level.
A frequent explanation for excess upper floor humidity is poor ventilation on the upper floor, which can cause greater 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 excessive moisture in that section of a home.
To address 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. Finding 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 helpful tool to manage humidity in the residence.
