Your entire home should be a retreat that’s warm and toasty in the winter and cool and comfortable in the summer. However, families who live in some multi-level residences find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could just be due to the fact most thermostats in a house are on the main floor, which is where people spend the the majority of time—in the living room, kitchen, etc.—so they 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 challenges can be fixed somewhat quickly while others might necessitate more extensive and costly fixes. Here, the team at Northglenn Heating & Air Conditioning will help you determine 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 becoming hotter than the downstairs can be chalked up to several factors. For starters, heat rises, so it’s normal 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 allowing 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 struggle to cool the upstairs sufficiently.
To tackle these issues, homeowners could install more insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the air conditioning unit is the right size for the home, call an experienced HVAC company like Northglenn Heating & Air Conditioning inspect the unit. A skilled professional also can help select 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 a frosty night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in 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 proper 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 locations of the building. However, issues with the ductwork can contribute to the upstairs being colder than the lower floor. A typical explanation for this is improper airflow balance. The ducts may not be the proper size or design, resulting in 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 possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they are not correctly positioned, it can restrict air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, decreasing 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 checked by trusted experts like the team at Northglenn Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help enhance 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 ground level of your residence, an HVAC zoning system could be an effective solution.
An HVAC zoning system separates the home into distinctive zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.
This system can be particularly useful in situations where the upstairs of a multi-story home is too hot or extremely 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 My Upstairs So Humid?
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 the first floor.
A frequent cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can produce increased 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 outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also create unwanted moisture in that level of a home.
To correct humidity problems, homeowners can increase 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 imperative.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another useful tool to control humidity on the upper and lower floors.
