Your entire residence 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 main floor.

This could simply be caused by the fact that most thermostats in a house are on the first floor, which is where people spend the most time—in the living room, kitchen, etc.—so it makes sense to set the temperature according to how it feels on the first floor.

However, temperature discrepancies between the upstairs and downstairs could also be because of trouble with your HVAC system. Some of these issues can be solved relatively quickly while others might necessitate more extensive and costly fixes. Here, the specialists at Air Masters Heating & Cooling will help you solve 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 feeling hotter than the downstairs can be attributed to several factors. Number one, heat rises, so it’s common for the second floor of a home to get hotter than the main floor. Lack of 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 air conditioning is not powerful enough to cool the entire home, causing it to have difficulty cooling the upstairs effectively.

To fix these issues, homeowners could install additional insulation in the attic and make sure their home has adequate ventilation. If there’s a question of whether the air conditioning unit is the proper size for the home, call an experienced HVAC company like Air Masters Heating & Cooling inspect the unit. A skilled professional also can help find a unit that's better suited for your home if you need air conditioning installation or replacement.

Why Is My Upstairs Colder/Not Heating?

When the downstairs of your home is warm, but it’s freezing upstairs, that makes for an ice-cold night for anyone whose bedrooms are on the upper floor. The most frequent reasons an upstairs not heating like it is supposed to are the insulation levels and the ductwork.

Inadequate insulation allows cold air to seep 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 solid, 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 very important role in circulating conditioned air throughout different rooms of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the main level. A frequently reported cause for this is improper airflow balance. The ducts may not be the correct size or configuration, causing an uneven distribution of air between the floors. This can cause more warm air to flow 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 story or they are poorly placed, it can reduce air circulation and cause inferior heating or cooling. In addition, leaks or gaps in the ductwork can allow air loss, reducing 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 Air Masters Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and installing additional vents or adjusting existing ones can help improve airflow and ensure a better 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 house, an HVAC zoning system could be a useful solution.

An HVAC zoning system divides the home 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 situations 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, making it possible for them to address specific hot or cold spots effortlessly.

Why Is it So Humid Upstairs?

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 lower level.

A typical explanation for excess upper floor humidity is poor ventilation on the upper floor, which can cause greater humidity levels. As is often the case with temperature differences between floors, insufficient insulation or sealing in the attic or walls may let warm, humid air from outside infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing issues on the upper floor, that can also cause excessive moisture in that level of a home.

To address 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 protect against external moisture from entering the upstairs. Identifying 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 helpful tool to manage humidity in your home.
