Every floor in your home should be a refuge that’s warm and cozy in the cold months 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 main floor.
This could merely be caused by the fact that 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 they set the temperature according to how it feels on the first floor.
However, temperature differences between the upstairs and downstairs could also be caused by problems with your HVAC system. Some of these issues can be sorted out relatively quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Connolly Electric & Mechanical 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 feeling hotter than the downstairs can be chalked up to several factors. Number one, 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 exacerbate this issue by allowing 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 sufficiently.
To address these issues, homeowners could install more insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the air conditioner is the ideal size for the home, call an experienced HVAC company like Connolly Electric & Mechanical inspect the unit. A skilled professional also can help locate 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 extremely chilly upstairs, that could result in a frosty night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation enables 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 important 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 critical role in circulating conditioned air throughout different areas of the building. However, troubles 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 proper 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, leaving insufficient airflow—which is the heated air—on the higher floors.
Another factor with ductwork is the location 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 substandard heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, lowering 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 checked by trusted HVAC pros like the team at Connolly Electric & Mechanical to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help increase airflow and ensure a more even 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 ground level of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system divides the household into distinct zones, which each have their own thermostat and damper system so the homeowner can modify the heating or cooling of each zone.
This system can be particularly beneficial in situations where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By installing a zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots effectively.

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 lower level.
A frequent reason for excess upper floor humidity is weak ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, inadequate insulation or sealing in the attic or walls may permit warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also create unwanted moisture in that area of a home.
To address humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Proper insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Identifying 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 manage humidity in the residence.
