Your entire residence should be a refuge that’s warm and comfy in the winter season 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 due to the fact most thermostats in a house are on the ground floor, which is where people spend the greatest amount 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 discrepancies between the upstairs and downstairs could also be caused by trouble with your HVAC system. Some of these issues can be sorted out somewhat quickly while others might require more extensive and costly fixes. Here, the professionals at Allstar Heating & Air Conditioning will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is It Hot Upstairs?
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 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 allowing 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 struggle to cool the upstairs effectively.
To tackle these issues, homeowners could install additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the AC is the correct size for the home, call an experienced HVAC company like Allstar Heating & Air Conditioning inspect the unit. A skilled professional also can help select 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 could result in a frosty night for anyone whose bedrooms are on the upper floor. The most common explanations for an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to seep through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on the upper levels. It’s crucial to make sure your home has a deep, 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 distributing conditioned air throughout different areas of the building. However, troubles with the ductwork can cause the upstairs being colder than the lower floor. A frequently reported cause for this is improper airflow balance. The ducts may not be the proper size or configuration, which results in an uneven distribution of air between the floors. This can cause more warm air to go downstairs, leaving 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 story or they are not correctly positioned, it can reduce air circulation and cause inadequate heating or cooling. Also, 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 find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted HVAC pros like the team at Allstar Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help improve 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 lower floors of your residence, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system divides the household 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 beneficial in instances where the upstairs of a multi-story home is quite hot or really cold while the main floor is comfortable. By setting up a zoning system, homeowners can regulate the temperature independently in each zone, making it possible for them to address specific hot or cold spots easily.

Why Is the Humidity So High 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 first floor.
A typical reason for excess upper floor humidity is poor ventilation on the upper floor, which can result in increased humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may allow warm, humid air from outside infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing issues on the upper floor, that can also cause excessive moisture in that level of a home.
To manage humidity problems, homeowners can add more 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 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 valuable tool to control humidity in the residence.
