Your entire home should be a retreat that’s warm and cozy in the winter and cool and comfortable in the summer. However, families who live in some two-story homes 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 ground floor, which is where people spend the greatest amount 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 variations between the upstairs and downstairs could also be due to issues with your HVAC system. Some of these difficulties can be fixed relatively quickly while others might call for more extensive and costly fixes. Here, the team at Bell Mechanical Services 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 becoming hotter than the downstairs can be traced to several factors. For starters, 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 allowing heat transfer from the roof into the upstairs rooms.

Another common reason is that the HVAC system is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs properly.

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 question of whether the air conditioner is the ideal size for the home, call an experienced HVAC company like Bell Mechanical Services inspect the unit. A qualified professional also can help find a unit that's better suited for your home if you need 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 makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent explanations for an upstairs not heating like it should are the insulation levels and the ductwork.

Inadequate insulation lets cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on the upper levels. It’s essential 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 critical role in distributing conditioned air throughout different areas of the building. However, problems with the ductwork can result in the upstairs being colder than the lower floor. A typical explanation for this is improper airflow balance. The ducts may not be the proper size or configuration, 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 upper story.

Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they are poorly installed, it can limit air circulation and cause inferior heating or cooling. Also, leaks or gaps in the ductwork can allow 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 experienced experts like the team at Bell Mechanical Services to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new 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 highly effective solution.

An HVAC zoning system divides the residence into different 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 very useful in situations where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By investing in a  zoning system, homeowners can regulate the temperature independently in each zone, enabling 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 challenge in multi-floor homes is when the upper floors are more humid than the first floor.

A typical 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. Plus, if there are any leaks or plumbing issues on the upper floor, that can also cause unwanted moisture in that section of a home.

To manage humidity problems, homeowners can increase 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 stop external moisture from entering the upstairs. Locating and repairing any leaks or plumbing issues is also imperative.

Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another worthwhile tool to control humidity in the residence.
