Every floor in your home should be a refuge that’s warm and comfy in the winter 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 simply be caused by the fact that 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 they set the temperature according to how it feels on the first floor.
However, temperature variations between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these difficulties can be fixed somewhat quickly while others might necessitate more extensive and costly fixes. Here, the specialists at The Air Squad will help you solve 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 getting hotter than the downstairs can be chalked up to several factors. Number one, heat rises, so it’s natural 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 allowing 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 adequately.
To address these issues, homeowners could put in extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the AC is the right size for the home, call an experienced HVAC company like The Air Squad inspect the unit. A qualified professional also can help select a unit that's better suited for your home if you require air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s extremely chilly upstairs, that could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it should are the insulation levels and the ductwork.
Inadequate insulation allows cold air to seep through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. It’s essential to make sure your home has a thick, 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 very important role in distributing conditioned air throughout different locations of the building. However, issues with the ductwork can contribute to the upstairs being colder than the lower floor. A common reason for this is improper airflow balance. The ducts may not be the correct size or configuration, creating 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 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 are poorly located, it can restrict air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by skilled experts like the team at The Air Squad to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help enhance airflow and ensure a better temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the ground level of your house, an HVAC zoning system could be a great solution.
An HVAC zoning system divides the household into different 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 especially beneficial in scenarios where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can regulate the temperature independently in each zone, enabling them to address specific hot or cold spots effortlessly.

Why Is it So Humid 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 upstairs is more humid than downstairs.
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, insufficient insulation or sealing in the attic or walls may allow warm, humid air from outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also create excess moisture in that area of a home.
To deal with humidity problems, homeowners can increase ventilation by installing fans or opening windows to promote airflow. Proper 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 useful tool to reduce humidity in the residence.
