Your entire residence should be a refuge that’s warm and toasty in the winter 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 main floor.

This could merely be due to the fact most thermostats in a house are on the main 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 differences between the upstairs and downstairs could also be due to trouble with your HVAC system. Some of these challenges can be resolved relatively quickly while others might necessitate more extensive and costly fixes. Here, the team at JTech Mechanical will help you figure out why the upstairs of your home is hotter than downstairs, or vice versa.

Why Is It Hotter Upstairs?

The phenomenon of the upstairs of a two-story home feeling hotter than the downstairs can be attributed to several factors. For starters, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Poor 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 sufficiently.

To address these issues, homeowners could add extra insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the AC is the proper size for the home, call an experienced HVAC company like JTech Mechanical inspect the unit. A qualified professional also can help select a unit that's better suited for your home if you want air conditioning installation or replacement.

Why Is My Upstairs Always Cold/Not Heating?

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

Inadequate insulation lets cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. It’s essential to make sure your home has a thick, 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, troubles with the ductwork can result in the upstairs being colder than the main level. A frequently reported reason for this is improper airflow balance. The ducts may not be the right size or design, causing an uneven distribution of air between the floors. This can cause more warm air to be directed to the downstairs, which creates insufficient airflow—which is the heated air—on the higher floors.

Another factor with ductwork is the placement of the supply and return vents. If there are fewer vents on the upper level or they are not correctly installed, it can restrict air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can lead to air loss, decreasing 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 inspected by trusted experts like the team at JTech Mechanical to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help improve airflow and ensure a more even 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 rest of your home, an HVAC zoning system could be a highly effective solution.

An HVAC zoning system breaks the residence 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 particularly helpful in instances where the upstairs of a multi-story home is too hot or too cold while the main floor is comfortable. By installing a  zoning system, homeowners can regulate the temperature independently in each zone, making it possible for 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 problem in multi-floor homes is when the upstairs is more humid than the first floor.

A common cause for excess upper floor humidity is inadequate ventilation on the upper floor, which can result in higher humidity levels. As is often the case with temperature differences between floors, inadequate 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 problems on the upper floor, that can also cause excess moisture in that area of a home.

To manage humidity problems, homeowners can increase 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 stop 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 reduce humidity in your home.
