Every floor in your home should be a sanctuary that’s warm and toasty 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 main floor.
This could just be due to the fact most thermostats in a house are on the main floor, which is where people spend the the majority of 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 trouble with your HVAC system. Some of these difficulties can be resolved somewhat quickly while others might require more extensive and costly fixes. Here, the professionals at Premium Air Services LLC will help you figure out 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 chalked up to several factors. Number one, heat rises, so it’s common for the second floor of a home to get hotter than the ground floor. Lack of insulation in the attic or roof can make this worse by permitting 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 struggle to cool the upstairs sufficiently.
To fix these issues, homeowners could put in additional insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the AC is the proper size for the home, call an experienced HVAC company like Premium Air Services LLC inspect the unit. A skilled professional also can help locate 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 a very chilly night for anyone whose bedrooms are on the upper floor. The most common explanations for an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to leak through the home’s attic or walls and contribute to heat loss, creating 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 circulating conditioned air throughout different areas of the building. However, problems with the ductwork can contribute to the upstairs being colder than the main level. A typical explanation for this is improper airflow balance. The ducts may not be the correct size or design, causing 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 possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they are poorly positioned, it can limit air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by experienced experts like the team at Premium Air Services LLC to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in more vents or adjusting existing ones can help improve 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 lower floors of your residence, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system separates the household 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 effective in scenarios where the upstairs of a multi-story home is quite hot or really cold while the main floor is comfortable. By implementing a zoning system, homeowners can regulate the temperature independently in each zone, allowing them to address specific hot or cold spots effortlessly.

Why Is My Upstairs So Humid?
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 typical cause for excess upper floor humidity is weak 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 allow warm, humid air from outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems on the upper floor, that can also cause extra moisture in that section of a home.
To fix humidity problems, homeowners can add more 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 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 helpful tool to control humidity in the residence.
