Your entire home should be a retreat that’s warm and cozy in the winter and cool and comfortable in the summer. However, owners of some homes with multiple levels find the upper floor is stubbornly hotter or colder than the rooms on ground level.

This could merely be due to the fact 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 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 due to issues with your HVAC system. Some of these challenges can be solved somewhat quickly while others might require more extensive and costly fixes. Here, the specialists at Premium Air Services LLC will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.

Why Is It Hotter Upstairs?

The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be attributed to several factors. For starters, heat rises, so it’s common for the second floor of a home to get hotter than the first floor. Poor insulation in the attic or roof can make this worse by letting heat transfer from the roof into the upstairs rooms.

Another common reason is that the HVAC system is not big enough to cool the entire home, causing it to struggle to cool the upstairs adequately.

To address these issues, homeowners could install more insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the air conditioning unit is the right size for the home, call an experienced HVAC company like Premium Air Services LLC inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you want air conditioning installation or replacement.

Why Is My Upstairs Colder/Not Heating?

When the downstairs of your home is warm, but it’s extremely chilly upstairs, that can cause a frosty night for anyone whose bedrooms are on the upper floor. The most common causes of 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, causing colder temperatures on higher floors. It’s essential to make sure your home has a thick, 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 very important role in distributing conditioned air throughout different rooms of the building. However, troubles with the ductwork can result in the upstairs being colder than the lower floor. A common cause for this is improper airflow balance. The ducts may not be the right size or in the appropriate layout, resulting in an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, causing insufficient airflow—which is the heated air—on the upper story.

Another potential problem area in the ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they aren't well positioned, it can restrict air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can cause air loss, reducing the overall efficiency of the HVAC system and making the temperature difference more pronounced.

To figure out why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced professionals like the team at Premium Air Services LLC to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help improve airflow and ensure a more consistent 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 ground level of your house, an HVAC zoning system could be a highly effective solution.

An HVAC zoning system breaks the residence into distinct zones, which each have their own thermostat and damper system so the homeowner can modify the heating or cooling of each zone.

This system can be especially effective in scenarios where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By investing in a  zoning system, homeowners can control the temperature independently in each zone, making it possible for them to address specific hot or cold spots effortlessly.

Why Is the Humidity So High Upstairs?

In addition to the upper story being hotter or colder than the rest of the house, another challenge in multi-floor homes is when the upstairs is more humid than the lower level.

A frequent cause for excess upper floor humidity is poor ventilation on the upper floor, which can result in increased 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 concerns on the upper floor, that can also create unwanted moisture in that level of a home.

To address humidity problems, homeowners can improve 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 prevent 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 useful tool to control humidity in your home.
