Every floor in your home should be a retreat that’s warm and comfy in the winter and cool and comfortable in the summer. However, residents in some two-story homes find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could just be caused by the fact that 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 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 due to problems with your HVAC system. Some of these challenges can be fixed relatively quickly while others might necessitate more extensive and costly fixes. Here, the team at Air Commander's Heating & Air Conditioning Co. will help you solve 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 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 worsen this problem by letting 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 fight to cool the upstairs effectively.
To address these issues, homeowners could put in additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioner is the right size for the home, call an experienced HVAC company like Air Commander's Heating & Air Conditioning Co. inspect the unit. A skilled professional also can help find a unit that's better suited for your home if you want 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 makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation lets cold air to filter through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures upstairs. It’s crucial to make sure your home has a solid, 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 very important role in disseminating conditioned air throughout different rooms of the building. However, problems with the ductwork can contribute to the upstairs being colder than the lower floor. A frequently reported reason for this is improper airflow balance. The ducts may not be the right size or design, which results in an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, causing insufficient airflow—which is the heated air—on the upper story.
Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they are poorly located, it can limit air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by skilled experts like the team at Air Commander's Heating & Air Conditioning Co. to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help increase airflow and ensure a more consistent 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 rest of your home, an HVAC zoning system could be a great solution.
An HVAC zoning system separates the residence into distinct 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 especially helpful in instances where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By setting up a zoning system, homeowners can control 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 problem in multi-floor homes is when the upstairs is more humid than downstairs.
A common cause for excess upper floor humidity is poor ventilation on the upper floor, which can produce increased 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. Plus, if there are any leaks or plumbing issues on the upper floor, that can also lead to excessive moisture in that level of a home.
To address humidity problems, homeowners can improve ventilation by installing 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. 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 useful tool to reduce humidity on the upper and lower floors.
