Your entire home should be a retreat that’s warm and toasty in the cold months 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 just be caused by the fact that most thermostats in a house are on the main floor, which is where people spend the most 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 differences between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these issues can be resolved somewhat quickly while others might necessitate more extensive and costly fixes. Here, the professionals at Premium Air Services LLC will help you solve why the upstairs of your home is hotter than downstairs, or vice versa.

Why Is It Hotter Upstairs?

The phenomenon of the upstairs of a two-story home becoming hotter than the downstairs can be attributed to several factors. Number one, heat rises, so it’s normal for the second floor of a home to get hotter than the ground floor. Not enough 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 strong enough to cool the entire home, causing it to struggle to cool the upstairs properly.

To tackle these issues, homeowners could add more insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the air conditioner is the correct size for the home, call an experienced HVAC company like Premium Air Services LLC inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you require 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 makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent causes of an upstairs not heating like it is supposed to 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, creating colder temperatures on the upper levels. It’s crucial to make sure your home has a deep, level layer of insulation in the attic and adequate insulation in the walls to keep the cold out and the heat inside.

The ductwork in a home plays a fundamental role in circulating conditioned air throughout different locations of the building. However, issues with the ductwork can result in the upstairs being colder than the downstairs. A frequently reported reason for this is improper airflow balance. The ducts may not be the proper size or configuration, which results in an uneven distribution of air between the floors. This can cause more warm air to go downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.

Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper floor or they aren't well positioned, it can reduce air circulation and cause substandard heating or cooling. In addition, leaks or gaps in the ductwork can lead to 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 examined by experienced experts like the team at Premium Air Services LLC to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in more vents or adjusting existing ones can help increase airflow and ensure a better 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 house, an HVAC zoning system could be an effective solution.

An HVAC zoning system breaks the home into distinct 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 beneficial in scenarios where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By installing a  zoning system, homeowners can regulate the temperature independently in each zone, making it possible for them to address specific hot or cold spots effortlessly.

Why Is the Humidity So High 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 downstairs.

A common 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, inadequate insulation or sealing in the attic or walls may allow warm, humid air from outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing concerns on the upper floor, that can also create excess moisture in that area of a home.

To correct humidity problems, homeowners can increase ventilation by installing fans or opening windows to promote airflow. Appropriate levels of insulation  in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Identifying 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 worthwhile tool to manage humidity on the upper and lower floors.
