Every floor in your home should be a sanctuary that’s warm and toasty 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 differences between the upstairs and downstairs could also be because of issues with your HVAC system. Some of these issues can be sorted out relatively quickly while others might call for more extensive and costly fixes. Here, the professionals at Speedy Air Conditioning 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 chalked up to several factors. Number one, 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 HVAC system is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs sufficiently.
To address these issues, homeowners could put in more insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioning unit is the ideal size for the home, call an experienced HVAC company like Speedy Air Conditioning inspect the unit. A skilled professional also can help locate 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 an ice-cold night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it ought 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, resulting in colder temperatures on higher floors. It’s important to make sure your home has a thick, level layer of insulation in the attic and adequate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a critical role in distributing conditioned air throughout different areas of the building. However, issues with the ductwork can contribute to the upstairs being colder than the lower floor. A common explanation for this is improper airflow balance. The ducts may not be the right size or design, which results in 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 upper level.
Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly positioned, it can reduce air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can lead to air loss, reducing the overall efficiency of the HVAC system and actually making the temperature difference worse.
To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted HVAC pros like the team at Speedy Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help improve airflow and ensure a more consistent temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the lower floors of your house, an HVAC zoning system could be a great solution.
An HVAC zoning system divides 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 too hot or too cold while the main floor is comfortable. By installing a zoning system, homeowners can regulate the temperature independently in each zone, enabling them to address specific hot or cold spots effortlessly.

Why Is it So Humid Upstairs?
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 upstairs is more humid than the first floor.
A typical explanation 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, inadequate insulation or sealing in the attic or walls may let warm, humid air from outdoors infiltrate the upstairs rooms. In addition, 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 correct humidity problems, homeowners can add more ventilation by using 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 valuable tool to control humidity in your home.
