Your entire residence should be a retreat 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 due to the fact 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 it makes sense to 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 issues with your HVAC system. Some of these issues can be fixed somewhat quickly while others might require more extensive and costly fixes. Here, the team at Walter's-Eaton's Electric, Plumbing, Heating & AC 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 becoming hotter than the downstairs can be chalked up to several factors. First, heat rises, so it’s natural 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 permitting 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 have difficulty cooling the upstairs properly.
To tackle these issues, homeowners could install additional insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioner is the ideal size for the home, call an experienced HVAC company like Walter's-Eaton's Electric, Plumbing, Heating & AC inspect the unit. A knowledgeable professional also can help select a unit that's better suited for your home if you need air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s very cold upstairs, that could result in a very chilly night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation enables cold air to filter through the home’s attic or walls and contribute to heat loss, causing colder temperatures on the upper levels. It’s essential to make sure your home has a solid, 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 fundamental 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 main level. A common cause 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 go downstairs, which creates insufficient airflow—which is the heated air—on the upper level.
Another potential problem area in the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they are not correctly placed, it can reduce air circulation and cause substandard heating or cooling. Additionally, 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 experienced experts like the team at Walter's-Eaton's Electric, Plumbing, Heating & AC to identify any imbalances, leaks or inadequacies. Sealing leaks and installing more vents or adjusting existing ones can help enhance 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 ground level of your home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system separates the residence into distinctive 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 useful in situations where the upstairs of a multi-story home is quite hot or really cold while the main floor is comfortable. By investing in a zoning system, homeowners can regulate 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 problem in multi-floor homes is when the upper floors are more humid than the lower level.
A common cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can cause 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 the house infiltrate the upstairs rooms. And, if there are any leaks or plumbing problems on the upper floor, that can also lead to extra moisture in that area of a home.
To correct humidity problems, homeowners can improve ventilation by installing 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. Finding 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 worthwhile tool to control humidity on the upper and lower floors.
