Every floor in your home should be a sanctuary that’s warm and cozy in the cold months and cool and comfortable in the summer. However, owners of some homes with multiple levels find the upper floor is stubbornly hotter or colder than the rooms on ground level.

This could just be because most thermostats in a house are on the ground floor, which is where people spend the the majority of 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 due to issues with your HVAC system. Some of these issues can be fixed relatively quickly while others might necessitate more extensive and costly fixes. Here, the professionals at LTS Plumbing & Heating Inc. will help you solve 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 getting hotter than the downstairs can be traced to several factors. First, heat rises, so it’s common 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 conditioner is not powerful enough to cool the entire home, causing it to struggle to cool the upstairs sufficiently.

To tackle these issues, homeowners could install extra 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 LTS Plumbing & Heating Inc. 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 Colder/Not Heating?

When the downstairs of your home is warm, but it’s extremely chilly upstairs, that makes for a very chilly night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it should are the insulation levels and the ductwork.

Inadequate insulation allows cold air to leak 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 deep, 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 fundamental role in circulating conditioned air throughout different locations of the building. However, problems with the ductwork can result in the upstairs being colder than the lower floor. A frequently reported cause for this is improper airflow balance. The ducts may not be the right size or configuration, resulting 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 upper level.

Another potential problem area in the ductwork is the layout 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. Additionally, leaks or gaps in the ductwork can allow air loss, decreasing the overall efficiency of the HVAC system and making the temperature difference more pronounced.

To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by skilled HVAC pros like the team at LTS Plumbing & Heating Inc. to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help improve airflow and ensure a better temperature balance between the upstairs and downstairs.

What Do I Do to Fix a Hot/Cold Upstairs?

If your upstairs is hotter or colder than the lower floors of your house, an HVAC zoning system could be a highly effective solution.

An HVAC zoning system divides the residence into distinctive zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.

This system can be very helpful in instances where the upstairs of a multi-story home is quite hot or extremely cold while the main floor is comfortable. By implementing a  zoning system, homeowners can regulate the temperature independently in each zone, allowing 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 issue in multi-floor homes is when the higher levels are more humid than the lower level.

A frequent reason for excess upper floor humidity is inadequate 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 allow warm, humid air from outdoors infiltrate the upstairs rooms. In addition, if there are any leaks or plumbing problems on the upper floor, that can also create extra moisture in that area of a home.

To deal with humidity problems, homeowners can add more ventilation by getting 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. Finding 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 reduce humidity in your home.
