Your entire home should be a retreat that’s warm and cozy in the winter season 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 rooms on ground level.
This could just be due to the fact most thermostats in a house are on the ground 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 differences between the upstairs and downstairs could also be due to problems with your HVAC system. Some of these challenges can be resolved somewhat quickly while others might require more extensive and costly fixes. Here, the professionals at County Line Mechanical LLC will help you figure out why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hotter Upstairs?
The phenomenon of the upstairs of a two-story home getting hotter than the downstairs can be traced to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Lack of insulation in the attic or roof can exacerbate this issue by allowing heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioner is not strong enough to cool the entire home, causing it to fight to cool the upstairs properly.
To address these issues, homeowners could put in extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the AC is the ideal size for the home, call an experienced HVAC company like County Line Mechanical LLC inspect the unit. A skilled 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 extremely chilly upstairs, that can cause a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation lets cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures upstairs. It’s essential to make sure your home has a deep, 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 disseminating conditioned air throughout different areas of the building. However, problems with the ductwork can contribute to the upstairs being colder than the downstairs. A typical explanation for this is improper airflow balance. The ducts may not be the correct size or configuration, 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 upper level.
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 positioned, it can limit air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted experts like the team at County Line Mechanical LLC to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional 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 home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system separates the home into different 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 helpful in scenarios where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can manage the temperature independently in each zone, allowing 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 issue in multi-floor homes is when the upstairs is more humid than the lower level.
A common reason 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, insufficient insulation or sealing in the attic or walls may let warm, humid air from outside the house infiltrate the upstairs rooms. And, if there are any leaks or plumbing problems on the upper floor, that can also create excessive moisture in that level of a home.
To correct 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 prevent external moisture from entering the upstairs. Identifying 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 worthwhile tool to reduce humidity in the residence.
