Your entire home should be a refuge that’s warm and toasty in the winter 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 just be caused by the fact that most thermostats in a house are on the first floor, which is where people spend the greatest amount of time—in the living room, kitchen, etc.—so they 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 trouble with your HVAC system. Some of these difficulties can be resolved relatively quickly while others might require more extensive and costly fixes. Here, the team at Just Right Heating and Cooling 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 getting hotter than the downstairs can be traced 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 make this worse by allowing 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 address these issues, homeowners could put in extra 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 Just Right Heating and Cooling inspect the unit. A skilled 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 So Cold/Not Heating?

When the downstairs of your home is warm, but it’s very cold upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most prevalent reasons 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 upstairs. It’s crucial to make sure your home has a thick, level layer of insulation in the attic and appropriate insulation in the walls to keep the cold out and the heat inside.

The ductwork in a home plays a very important 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 typical explanation for this is improper airflow balance. The ducts may not be the right size or design, resulting in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.

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 placed, it can reduce air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can lead to air loss, lowering 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 examined by skilled professionals like the team at Just Right Heating and Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help increase 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 useful solution.

An HVAC zoning system separates the home 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 useful in scenarios where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By investing in a  zoning system, homeowners can control 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 issue in multi-floor homes is when the upper floors are more humid than downstairs.

A frequent cause for excess upper floor humidity is poor ventilation on the upper floor, which can produce higher humidity levels. As is often the case with temperature differences between floors, insufficient 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 problems on the upper floor, that can also lead to unwanted moisture in that section of a home.

To deal with humidity problems, homeowners can add more ventilation by installing fans or opening windows to promote airflow. Appropriate levels of 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 helpful tool to control humidity in your home.
