Every floor in your home should be a sanctuary that’s warm and comfy in the winter and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could merely be caused by the fact that most thermostats in a house are on the ground 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 differences between the upstairs and downstairs could also be caused by problems with your HVAC system. Some of these difficulties can be resolved relatively quickly while others might require more extensive and costly fixes. Here, the specialists at Air-Right Energy Design 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 feeling hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the main floor. Not enough insulation in the attic or roof can make this worse 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 sufficiently.
To tackle these issues, homeowners could put in extra insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the air conditioner is the correct size for the home, call an experienced HVAC company like Air-Right Energy Design inspect the unit. A skilled professional also can help locate a unit that's better suited for your home if you are considering air conditioning installation or replacement.
Why Is My Upstairs So Cold/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that can cause an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to filter through the home’s attic or walls and contribute to heat loss, creating colder temperatures upstairs. It’s important to make sure your home has a deep, 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 fundamental role in distributing conditioned air throughout different rooms of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A common cause for this is improper airflow balance. The ducts may not be the proper size or configuration, creating an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.
Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they aren't well located, it can restrict air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced HVAC pros like the team at Air-Right Energy Design to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help enhance 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 ground level of your residence, an HVAC zoning system could be a great solution.
An HVAC zoning system divides the household into distinctive zones, which each have their own thermostat and damper system so the homeowner can customize the heating or cooling of each zone.
This system can be especially helpful in instances 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, making it possible for 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 issue in multi-floor homes is when the upstairs is more humid than the lower level.
A common cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can produce increased humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may permit 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 cause unwanted moisture in that section of a home.
To fix humidity problems, homeowners can add more ventilation by getting 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. 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 manage humidity on the upper and lower floors.
