Your entire residence 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 multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.

This could just be caused by the fact that 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 due to issues with your HVAC system. Some of these difficulties can be sorted out relatively quickly while others might call for more extensive and costly fixes. Here, the team at Bain Heating & Air Conditioning will help you figure out 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. Number one, heat rises, so it’s common for the second floor of a home to get hotter than the first floor. Not enough insulation in the attic or roof can worsen this problem by letting 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 struggle to cool the upstairs sufficiently.

To deal with 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 conditioner is the ideal size for the home, call an experienced HVAC company like Bain 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 So Cold/Not Heating?

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

Inadequate insulation permits cold air to filter through the home’s attic or walls and contribute to heat loss, creating 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 critical role in disseminating conditioned air throughout different locations of the building. However, problems with the ductwork can cause the upstairs being colder than the downstairs. A common reason for this is improper airflow balance. The ducts may not be the proper size or in the appropriate layout, creating an uneven distribution of air between the floors. This can cause more warm air to flow 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 are poorly installed, it can reduce air circulation and cause inferior heating or cooling. Additionally, 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 determine why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by trusted professionals like the team at Bain Heating & Air Conditioning to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help increase airflow and ensure a more consistent 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 lower floors of your house, an HVAC zoning system could be a useful solution.

An HVAC zoning system divides the home into distinct 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 especially beneficial in situations where the upstairs of a multi-story home is very hot or too 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 My Upstairs So Humid?

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 lower level.

A typical reason for excess upper floor humidity is weak ventilation on the upper floor, which can produce higher humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may allow warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing concerns on the upper floor, that can also lead to 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. Proper 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 critical.

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