Every floor in your home should be a refuge that’s warm and cozy in the winter season and cool and comfortable in the summer. However, families who live in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the first floor.
This could merely be because most thermostats in a house are on the main 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 trouble with your HVAC system. Some of these issues can be solved relatively quickly while others might require more extensive and costly fixes. Here, the team at Mechanical Air Systems Co will help you solve 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 getting hotter than the downstairs can be traced to several factors. For starters, heat rises, so it’s common for the second floor of a home to get hotter than the main floor. Insufficient 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 air conditioner is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To fix these issues, homeowners could put in more insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the AC is the ideal size for the home, call an experienced HVAC company like Mechanical Air Systems Co inspect the unit. A knowledgeable professional also can help find 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 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 is supposed 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, resulting in colder temperatures upstairs. It’s important to make sure your home has a thick, 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 locations of the building. However, problems with the ductwork can result in the upstairs being colder than the main level. A common reason for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, 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 level.
Another potential problem area in the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper floor or they aren't well positioned, it can limit air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can lead to air loss, lowering the overall efficiency of the HVAC system and actually making the temperature difference worse.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced professionals like the team at Mechanical Air Systems Co to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in additional vents or adjusting existing ones can help enhance airflow and ensure a more even temperature balance between the upstairs and downstairs.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the rest of your residence, an HVAC zoning system could be a useful solution.
An HVAC zoning system divides the residence 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 particularly beneficial in scenarios where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By implementing a zoning system, homeowners can manage the temperature independently in each zone, making it possible for them to address specific hot or cold spots effortlessly.

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 upper floors are more humid than the lower level.
A common explanation for excess upper floor humidity is inadequate 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 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 lead to excessive moisture in that area of a home.
To correct humidity problems, homeowners can add more ventilation by installing fans or opening windows to promote airflow. Adding more insulation in the attic and better sealing the attic and walls can help prevent 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 manage humidity on the upper and lower floors.
