Your entire home should be a retreat that’s warm and cozy in the winter season and cool and comfortable in the summer. However, families who live in some two-story homes find the upper floor is stubbornly hotter or colder than the first floor.

This could merely be due to the fact 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 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 specialists at Everest 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 chalked up to several factors. Number one, heat rises, so it’s natural for the second floor of a home to get hotter than the main 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 conditioner is not strong enough to cool the entire home, causing it to struggle to cool the upstairs effectively.

To deal with these issues, homeowners could add extra insulation in the attic and make sure their home has sufficient ventilation. If there’s concern the AC is the proper size for the home, call an experienced HVAC company like Everest Heating & Cooling inspect the unit. A qualified professional also can help find a unit that's better suited for your home if you want 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 could result in an ice-cold night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it ought to are the insulation levels and the ductwork.

Inadequate insulation allows cold air to filter through the home’s attic or walls and contribute to heat loss, creating colder temperatures on higher floors. It’s important 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 areas of the building. However, issues with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported cause for this is improper airflow balance. The ducts may not be the correct 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 story.

Another potential problem area in the ductwork is the location of the supply and return vents. If there are fewer vents on the upper level or they are not correctly located, it can limit air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can lead to air loss, reducing the overall efficiency of the HVAC system and exacerbating the temperature difference.

To find out why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by trusted experts like the team at Everest Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help increase 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 highly effective solution.

An HVAC zoning system breaks the household into different zones, which each have their own thermostat and damper system so the homeowner can customize the heating or cooling of each zone.

This system can be especially helpful in scenarios where the upstairs of a multi-story home is very hot or really cold while the main floor is comfortable. By installing a  zoning system, homeowners can regulate the temperature independently in each zone, allowing them to address specific hot or cold spots effectively.

Why Is My Upstairs So Humid?

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 upstairs is more humid than the lower level.

A common 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, insufficient insulation or sealing in the attic or walls may permit warm, humid air from outside infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing concerns on the upper floor, that can also cause excess moisture in that level of a home.

To correct humidity problems, homeowners can improve ventilation by getting fans or opening windows to promote airflow. Adding more insulation  in the attic and better sealing the attic and walls can help prevent external moisture from entering the upstairs. Finding 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 on the upper and lower floors.
