Your entire home should be a sanctuary that’s warm and toasty in the cold months and cool and comfortable in the summer. However, residents in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the rooms on ground level.
This could merely be caused by the fact that 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 as a result they tend 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 problems 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 specialists at Tokay will help you figure out 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. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Lack of insulation in the attic or roof can worsen this problem by letting 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 fight to cool the upstairs properly.
To address these issues, homeowners could install extra insulation in the attic and make sure their home has sufficient ventilation. If there’s a possibility the air conditioning unit is the right size for the home, call an experienced HVAC company like Tokay 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 very cold upstairs, that makes for a frosty night for anyone whose bedrooms are on the upper floor. The most common explanations for an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation enables 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 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 critical role in distributing conditioned air throughout different locations of the building. However, troubles with the ductwork can result in the upstairs being colder than the lower floor. A typical reason for this is improper airflow balance. The ducts may not be the proper size or configuration, 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 story.
Another factor with ductwork is the layout of the supply and return vents. If there are fewer vents on the upper level or they are not correctly placed, it can limit air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, lowering 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 inspected by experienced HVAC pros like the team at Tokay 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.
What Do I Do to Fix a Hot/Cold Upstairs?
If your upstairs is hotter or colder than the lower floors of your residence, an HVAC zoning system could be an effective solution.
An HVAC zoning system separates the home 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 very beneficial in situations 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, enabling 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 problem in multi-floor homes is when the upstairs is more humid than the lower level.
A typical explanation for excess upper floor humidity is weak ventilation on the upper floor, which can result in greater 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 issues on the upper floor, that can also lead to excess moisture in that section of a home.
To fix humidity problems, homeowners can improve ventilation by using fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help prevent external moisture from entering the upstairs. Locating and repairing any leaks or plumbing issues is also extremely important.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another helpful tool to control humidity on the upper and lower floors.
