Your entire residence should be a sanctuary that’s warm and cozy 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 first floor.

This could just be caused by the fact that most thermostats in a house are on the first floor, which is where people spend the the majority of 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 caused by trouble with your HVAC system. Some of these difficulties can be resolved fairly quickly while others might require more extensive and costly fixes. Here, the specialists at Booneville Heating & Cooling will help you determine 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 attributed to several factors. Number one, heat rises, so it’s common for the second floor of a home to get hotter than the main floor. Insufficient insulation in the attic or roof can make this worse by allowing heat transfer from the roof into the upstairs rooms.

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

To deal with these issues, homeowners could install more insulation in the attic and make sure their home has adequate ventilation. If there’s a possibility the air conditioner is the right size for the home, call an experienced HVAC company like Booneville Heating & Cooling inspect the unit. A qualified 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 Colder/Not Heating?

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

Inadequate insulation lets cold air to seep through the home’s attic or walls and contribute to heat loss, causing colder temperatures upstairs. It’s crucial to make sure your home has a solid, 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 circulating conditioned air throughout different rooms of the building. However, problems with the ductwork can result in the upstairs being colder than the downstairs. A typical cause for this is improper airflow balance. The ducts may not be the correct size or design, 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 level.

Another possible issue with the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they aren't well positioned, it can reduce air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can cause air loss, lowering the overall efficiency of the HVAC system and exacerbating the temperature difference.

To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork inspected by experienced professionals like the team at Booneville Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and adding additional vents or adjusting existing ones can help improve airflow and ensure a more even temperature balance between the upstairs and downstairs.

Fixing the Hot or Cold Upstairs Problem?

If your upstairs is hotter or colder than the rest of your residence, an HVAC zoning system could be a great solution.

An HVAC zoning system separates the home 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 especially beneficial in situations where the upstairs of a multi-story home is too hot or extremely cold while the main floor is comfortable. By installing a  zoning system, homeowners can regulate the temperature independently in each zone, enabling 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 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, poor insulation or sealing in the attic or walls may permit warm, humid air from outside the house infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also cause unwanted moisture in that section of a home.

To address humidity problems, homeowners can increase ventilation by installing fans or opening windows to promote airflow. Adding more 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 valuable tool to control humidity in your home.
