Your entire residence should be a refuge that’s warm and cozy in the winter season and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.

This could merely be caused by the fact that most thermostats in a house are on the ground 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 discrepancies between the upstairs and downstairs could also be because of trouble 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 team at AW Heating & Air Conditioning will help you determine why the upstairs of your home is hotter than downstairs, or vice versa.

Why Is It Hot Upstairs?

The phenomenon of the upstairs of a two-story home feeling hotter than the downstairs can be attributed to several factors. Number one, heat rises, so it’s common for the second floor of a home to get hotter than the ground floor. Poor 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 HVAC system is not strong enough to cool the entire home, causing it to struggle to cool the upstairs sufficiently.

To address these issues, homeowners could put in additional insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the AC is the ideal size for the home, call an experienced HVAC company like AW Heating & Air Conditioning inspect the unit. A skilled professional also can help select 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 prevalent causes of an upstairs not heating like it should 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, causing 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 circulating conditioned air throughout different locations of the building. However, problems with the ductwork can result in the upstairs being colder than the downstairs. A common cause for this is improper airflow balance. The ducts may not be the right size or configuration, creating 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 factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they are poorly placed, it can limit air circulation and cause inferior heating or cooling. Additionally, leaks or gaps in the ductwork can allow air loss, reducing the overall efficiency of the HVAC system and making the temperature difference more pronounced.

To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by skilled experts like the team at AW Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in additional vents or adjusting existing ones can help increase airflow and ensure a more even temperature balance between the upstairs and downstairs.

How You Can Fix a Hot or Cold Upstairs?

If your upstairs is hotter or colder than the ground level of your residence, an HVAC zoning system could be a useful solution.

An HVAC zoning system divides the household into distinct 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 helpful in instances where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By implementing a  zoning system, homeowners can regulate the temperature independently in each zone, making it possible for them to address specific hot or cold spots easily.

Why Is it So Humid Upstairs?

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 the first floor.

A common explanation for excess upper floor humidity is inadequate 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 permit warm, humid air from outside the house infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems on the upper floor, that can also create excessive moisture in that level of a home.

To address humidity problems, homeowners can add more 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 stop external moisture from entering the upstairs. Identifying 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 reduce humidity in your home.
