Your entire home should be a sanctuary that’s warm and comfy in the cold months 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 simply be due to the fact most thermostats in a house are on the first floor, which is where people spend the most 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 trouble with your HVAC system. Some of these challenges can be fixed relatively quickly while others might call for more extensive and costly fixes. Here, the specialists at Air Masters Heating & Cooling will help you determine 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 feeling hotter than the downstairs can be attributed to several factors. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Poor 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 air conditioner is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.
To address these issues, homeowners could put in more insulation in the attic and make sure their home has proper ventilation. If there’s concern the air conditioning unit is the right size for the home, call an experienced HVAC company like Air Masters Heating & Cooling inspect the unit. A knowledgeable 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 So Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation lets cold air to seep through the home’s attic or walls and contribute to heat loss, creating 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 adequate 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 areas of the building. However, problems with the ductwork can result in the upstairs being colder than the downstairs. A frequently reported cause 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, which creates insufficient airflow—which is the heated air—on the upper story.
Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they aren't well installed, it can reduce air circulation and cause substandard heating or cooling. Also, leaks or gaps in the ductwork can lead to 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 checked by trusted experts like the team at Air Masters Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help improve airflow and ensure a better 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 lower floors of your residence, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system breaks the residence into different 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 useful in scenarios where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By setting up 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 upper floors are more humid than the first floor.
A common cause for excess upper floor humidity is poor ventilation on the upper floor, which can cause increased humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may let warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also create excessive moisture in that section of a home.
To address humidity problems, homeowners can improve ventilation by using fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help prevent 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 the residence.
