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

This could simply be because 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 as a result they tend to set the temperature according to how it feels on the first floor.

However, temperature variations between the upstairs and downstairs could also be due to trouble with your HVAC system. Some of these difficulties can be fixed fairly quickly while others might necessitate more extensive and costly fixes. Here, the specialists at Parker County Cooling & Heating 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. Number one, heat rises, so it’s normal 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 powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs sufficiently.

To address these issues, homeowners could add extra insulation in the attic and make sure their home has proper ventilation. If there’s a question of whether the AC is the correct size for the home, call an experienced HVAC company like Parker County Cooling & Heating inspect the unit. A knowledgeable professional also can help find a unit that's better suited for your home if you are considering 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 a very chilly night for anyone whose bedrooms are on the upper floor. The most frequent causes of an upstairs not heating like it should 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, resulting in colder temperatures upstairs. It’s important to make sure your home has a thick, level layer of insulation in the attic and appropriate 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 contribute to the upstairs being colder than the lower floor. A common cause for this is improper airflow balance. The ducts may not be the correct size or design, which results 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 factor with ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they are poorly positioned, it can reduce air circulation and cause substandard heating or cooling. In addition, 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 inspected by skilled professionals like the team at Parker County Cooling & Heating to identify any imbalances, leaks or inadequacies. Sealing leaks and adding more vents or adjusting existing ones can help improve 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 ground level of your home, 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 instances where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By investing in a  zoning system, homeowners can regulate the temperature independently in each zone, making it possible for them to address specific hot or cold spots effectively.

Why Is it So Humid 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 the first floor.

A typical reason for excess upper floor humidity is poor ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may let warm, humid air from outdoors infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also create unwanted moisture in that section of a home.

To deal with humidity problems, homeowners can increase 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 stop 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 manage humidity on the upper and lower floors.
