Every floor in your home should be a retreat that’s warm and cozy in the winter season 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 first floor.

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 as a result they tend 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 issues with your HVAC system. Some of these challenges can be resolved fairly quickly while others might necessitate more extensive and costly fixes. Here, the team at Fal-Ken Heating & Cooling Corporation 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 getting hotter than the downstairs can be attributed to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the main floor. Insufficient insulation in the attic or roof can exacerbate this issue by letting 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 struggle to cool the upstairs sufficiently.

To address these issues, homeowners could add additional insulation in the attic and make sure their home has proper ventilation. If there’s concern the air conditioning unit is the right size for the home, call an experienced HVAC company like Fal-Ken Heating & Cooling Corporation inspect the unit. A skilled professional also can help select 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 can cause a very chilly night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it should are the insulation levels and the ductwork.

Inadequate insulation enables cold air to filter 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 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 disseminating conditioned air throughout different areas of the building. However, troubles with the ductwork can cause the upstairs being colder than the main level. A common reason for this is improper airflow balance. The ducts may not be the correct size or configuration, causing 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 possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper story or they are not correctly located, it can reduce air circulation and cause inadequate 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 understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted experts like the team at Fal-Ken Heating & Cooling Corporation to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help enhance airflow and ensure a better temperature balance between the upstairs and downstairs.

Fixing the Hot or Cold Upstairs Problem?

If your upstairs is hotter or colder than the ground level of your home, an HVAC zoning system could be an 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 modify the heating or cooling of each zone.

This system can be very beneficial in scenarios where the upstairs of a multi-story home is very 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, enabling them to address specific hot or cold spots effortlessly.

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 lower level.

A typical explanation for excess upper floor humidity is inadequate 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 permit warm, humid air from outdoors infiltrate the upstairs rooms. And, if there are any leaks or plumbing problems on the upper floor, that can also cause extra moisture in that level of a home.

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

Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another useful tool to manage humidity in your home.
