Your entire home should be a retreat that’s warm and cozy in the winter and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could just 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 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 solved fairly quickly while others might necessitate more extensive and costly fixes. Here, the team at Covington Air Systems will help you figure out 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 feeling hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the first 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 conditioning is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.
To address these issues, homeowners could install extra insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the AC is the correct size for the home, call an experienced HVAC company like Covington Air Systems 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 Colder/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation permits cold air to leak 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 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 rooms of the building. However, problems with the ductwork can result in the upstairs being colder than the lower floor. A common cause for this is improper airflow balance. The ducts may not be the correct size or design, which results in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, which creates insufficient airflow—which is the heated air—on the upper story.
Another factor with ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they aren't well positioned, it can reduce air circulation and cause inadequate heating or cooling. Additionally, 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 determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by trusted experts like the team at Covington Air Systems to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help improve 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 house, an HVAC zoning system could be a useful 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 particularly beneficial in scenarios where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By investing in a zoning system, homeowners can control 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 challenge in multi-floor homes is when the higher levels are more humid than downstairs.
A frequent reason for excess upper floor humidity is weak ventilation on the upper floor, which can produce greater 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. And, if there are any leaks or plumbing concerns on the upper floor, that can also cause extra moisture in that section of a home.
To address 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 protect against external moisture from entering the upstairs. Finding and repairing any leaks or plumbing issues is also critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another helpful tool to reduce humidity in your home.
