Your entire home should be a retreat 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 main floor.
This could merely be due to the fact most thermostats in a house are on the first floor, which is where people spend the the majority of 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 discrepancies between the upstairs and downstairs could also be because of problems with your HVAC system. Some of these issues can be fixed relatively quickly while others might necessitate more extensive and costly fixes. Here, the team at J & J Air Conditioning 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 getting hotter than the downstairs can be chalked up to several factors. For starters, heat rises, so it’s common for the second floor of a home to get hotter than the ground floor. Poor insulation in the attic or roof can make this worse by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not big enough to cool the entire home, causing it to struggle to cool the upstairs sufficiently.
To deal with 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 right size for the home, call an experienced HVAC company like J & J Air Conditioning inspect the unit. A knowledgeable professional also can help find a unit that's better suited for your home if you require air conditioning installation or replacement.
Why Is My Upstairs Always 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 common causes of an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation permits cold air to seep through the home’s attic or walls and contribute to heat loss, creating colder temperatures on higher floors. It’s crucial to make sure your home has a solid, 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 disseminating conditioned air throughout different rooms of the building. However, issues with the ductwork can result in the upstairs being colder than the lower floor. A common reason for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, creating an uneven distribution of air between the floors. This can cause more warm air to go downstairs, causing insufficient airflow—which is the heated air—on the higher floors.
Another possible issue with the ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they are not correctly installed, it can restrict air circulation and cause substandard heating or cooling. Also, leaks or gaps in the ductwork can allow air loss, decreasing 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 checked by trusted experts like the team at J & J Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and installing new vents or adjusting existing ones can help improve airflow and ensure a more consistent 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 home, an HVAC zoning system could be a useful solution.
An HVAC zoning system separates the household into distinct 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 helpful in instances where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By installing a zoning system, homeowners can control the temperature independently in each zone, making it possible for them to address specific hot or cold spots effectively.

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 first floor.
A typical 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, insufficient 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 concerns on the upper floor, that can also lead to unwanted moisture in that area of a home.
To manage humidity problems, homeowners can add more ventilation by getting fans or opening windows to promote airflow. Adding more 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 critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another valuable tool to reduce humidity on the upper and lower floors.
