Your entire home should be a sanctuary that’s warm and toasty in the winter and cool and comfortable in the summer. However, families who live in some multi-level residences find the upper floor is stubbornly hotter or colder than the rooms on ground level.

This could simply be due to the fact most thermostats in a house are on the ground floor, which is where people spend the most time—in the living room, kitchen, etc.—so they 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 solved fairly quickly while others might necessitate more extensive and costly fixes. Here, the team at HCE Systems will help you solve 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 getting hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s normal for the second floor of a home to get hotter than the first floor. Insufficient insulation in the attic or roof can worsen this problem by allowing heat transfer from the roof into the upstairs rooms.

Another common reason is that the air conditioning is not powerful enough to cool the entire home, causing it to fight to cool the upstairs adequately.

To tackle these issues, homeowners could add more insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the air conditioning unit is the correct size for the home, call an experienced HVAC company like HCE Systems 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 Always Cold/Not Heating?

When the downstairs of your home is warm, but it’s freezing upstairs, that could result in a frosty night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it ought to are the insulation levels and the ductwork.

Inadequate insulation lets cold air to filter through the home’s attic or walls and contribute to heat loss, causing colder temperatures on the upper levels. 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 fundamental role in disseminating conditioned air throughout different areas of the building. However, problems with the ductwork can contribute to the upstairs being colder than the main level. A typical reason for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, which results 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 higher floors.

Another factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper story or they are poorly placed, it can reduce air circulation and cause inadequate heating or cooling. Also, leaks or gaps in the ductwork can cause air loss, decreasing 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 experts like the team at HCE Systems 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 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 rest of your house, an HVAC zoning system could be a highly effective solution.

An HVAC zoning system separates the residence into distinctive 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 particularly helpful in scenarios 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 manage 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 challenge in multi-floor homes is when the higher levels are more humid than the first floor.

A frequent cause for excess upper floor humidity is weak ventilation on the upper floor, which can cause 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 outdoors infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also create excessive moisture in that area of a home.

To manage humidity problems, homeowners can add more ventilation by using fans or opening windows to promote airflow. Proper insulation  in the attic and better sealing the attic and walls can help protect against 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 helpful tool to control humidity in the residence.
