Your entire residence 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 first floor.
This could just be caused by the fact that 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 variations between the upstairs and downstairs could also be because of issues with your HVAC system. Some of these challenges can be sorted out somewhat quickly while others might require more extensive and costly fixes. Here, the specialists at Precision Mechanical 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 becoming hotter than the downstairs can be attributed 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. Lack of 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 strong enough to cool the entire home, causing it to struggle to cool the upstairs effectively.
To tackle these issues, homeowners could add additional insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the air conditioning unit is the right size for the home, call an experienced HVAC company like Precision Mechanical inspect the unit. A knowledgeable professional also can help locate 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 extremely chilly upstairs, that could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it is supposed 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, creating colder temperatures on higher floors. It’s crucial 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 fundamental role in disseminating conditioned air throughout different rooms of the building. However, issues with the ductwork can cause the upstairs being colder than the main level. A common reason for this is improper airflow balance. The ducts may not be the correct size or configuration, which results in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.
Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they are poorly installed, it can reduce air circulation and cause inadequate heating or cooling. In addition, leaks or gaps in the ductwork can lead to air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.
To determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced experts like the team at Precision Mechanical to identify any imbalances, leaks or inadequacies. Sealing leaks and installing additional vents or adjusting existing ones can help improve airflow and ensure a more even 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 residence, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system breaks the home 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 very helpful in instances where the upstairs of a multi-story home is very hot or extremely cold while the main floor is comfortable. By installing a zoning system, homeowners can regulate 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 upstairs is more humid than the first floor.
A frequent reason for excess upper floor humidity is weak ventilation on the upper floor, which can result in 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 outside infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also create 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 prevent external moisture from entering the upstairs. Identifying 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 worthwhile tool to reduce humidity in the residence.
