Your entire residence should be a refuge that’s warm and toasty in the cold months and cool and comfortable in the summer. However, residents in some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.

This could merely 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 variations between the upstairs and downstairs could also be caused by issues with your HVAC system. Some of these difficulties can be solved fairly quickly while others might call for more extensive and costly fixes. Here, the professionals at Patterson & Stirling 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 attributed to several factors. For starters, heat rises, so it’s normal for the second floor of a home to get hotter than the main floor. Lack of 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 conditioner 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 additional insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the AC is the correct size for the home, call an experienced HVAC company like Patterson & Stirling inspect the unit. A qualified professional also can help locate a unit that's better suited for your home if you need air conditioning installation or replacement.

Why Is My Upstairs Always Cold/Not Heating?

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

Inadequate insulation lets cold air to filter through the home’s attic or walls and contribute to heat loss, creating colder temperatures on higher floors. It’s crucial to make sure your home has a deep, 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 very important role in circulating conditioned air throughout different rooms of the building. However, issues with the ductwork can result in 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 in the appropriate layout, which results in 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 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 story or they aren't well installed, it can limit air circulation and cause inferior 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 making the temperature difference more pronounced.

To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork examined by skilled experts like the team at Patterson & Stirling to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in new vents or adjusting existing ones can help increase 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 ground level of your residence, an HVAC zoning system could be a useful solution.

An HVAC zoning system divides the household into distinctive 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 very useful in instances 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 control the temperature independently in each zone, enabling 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 upper floors are more humid than the first floor.

A typical cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can produce increased 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 outdoors infiltrate the upstairs rooms. And, if there are any leaks or plumbing concerns on the upper floor, that can also lead to unwanted moisture in that section of a home.

To deal with 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 stop external moisture from entering the upstairs. Locating 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 valuable tool to control humidity in your home.
