Your entire residence should be a retreat that’s warm and comfy in the winter season and cool and comfortable in the summer. However, owners of some homes with multiple levels find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could just be because most thermostats in a house are on the main floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so they 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 problems with your HVAC system. Some of these issues can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the team at H&C Heating and Cooling will help you determine 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 feeling hotter than the downstairs can be chalked up to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Poor insulation in the attic or roof can exacerbate this issue by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not big enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.
To fix these issues, homeowners could install extra insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioner is the ideal size for the home, call an experienced HVAC company like H&C Heating and Cooling inspect the unit. A knowledgeable professional also can help find a unit that's better suited for your home if you are considering 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 can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to filter through the home’s attic or walls and contribute to heat loss, causing colder temperatures on higher floors. It’s crucial to make sure your home has a deep, level layer of insulation in the attic and adequate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a fundamental role in circulating conditioned air throughout different rooms of the building. However, problems with the ductwork can contribute to the upstairs being colder than the main level. A typical cause for this is improper airflow balance. The ducts may not be the proper size or configuration, resulting in an uneven distribution of air between the floors. This can cause more warm air to go downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.
Another potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they aren't well placed, it can reduce air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, decreasing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted experts like the team at H&C Heating and Cooling 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 more even temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the lower floors of your home, 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 very helpful in scenarios where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By implementing a zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots easily.

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 upstairs is more humid than the first floor.
A frequent reason for excess upper floor humidity is inadequate ventilation on the upper floor, which can produce higher 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 outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also create extra moisture in that area of a home.
To manage humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Adding more insulation in the attic and better sealing the attic and walls can help stop external moisture from entering the upstairs. Locating 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 valuable tool to control humidity in your home.
