Your entire home should be a retreat that’s warm and toasty in the winter season and cool and comfortable in the summer. However, residents in some homes with multiple levels find the upper floor is stubbornly hotter or colder than the rooms on ground level.

This could just be because most thermostats in a house are on the ground floor, which is where people spend the greatest amount of 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 because of problems with your HVAC system. Some of these difficulties can be solved somewhat quickly while others might require more extensive and costly fixes. Here, the professionals at Booneville Heating & Cooling will help you figure out 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 chalked up to several factors. First, heat rises, so it’s natural for the second floor of a home to get hotter than the first floor. Not enough insulation in the attic or roof can worsen this problem by permitting heat transfer from the roof into the upstairs rooms.

Another common reason is that the HVAC system is not strong enough to cool the entire home, causing it to struggle to cool the upstairs adequately.

To tackle these issues, homeowners could put in extra insulation in the attic and make sure their home has proper ventilation. If there’s a possibility the AC is the ideal size for the home, call an experienced HVAC company like Booneville Heating & Cooling inspect the unit. A knowledgeable professional also can help find a unit that's better suited for your home if you require air conditioning installation or replacement.

Why Is My Upstairs Always Cold/Not Heating?

When the downstairs of your home is warm, but it’s freezing upstairs, that can cause a very chilly night for anyone whose bedrooms are on the upper floor. The most prevalent explanations for an upstairs not heating like it is supposed 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, causing colder temperatures on the upper levels. It’s important to make sure your home has a thick, level layer of insulation in the attic and adequate insulation in the walls to keep the cold out and the heat inside.

The ductwork in a home plays a very important role in disseminating conditioned air throughout different rooms of the building. However, troubles with the ductwork can contribute to the upstairs being colder than the downstairs. A common reason for this is improper airflow balance. The ducts may not be the proper size or design, causing an uneven distribution of air between the floors. This can cause more warm air to go downstairs, leaving insufficient airflow—which is the heated air—on the higher floors.

Another possible issue with the ductwork is the location of the supply and return vents. If there are fewer vents on the upper floor or they are not correctly installed, it can limit air circulation and cause inadequate heating or cooling. Additionally, leaks or gaps in the ductwork can cause 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 examined by experienced HVAC pros like the team at Booneville Heating & Cooling to identify any imbalances, leaks or inadequacies. Sealing leaks and putting in additional vents or adjusting existing ones can help enhance airflow and ensure a better temperature balance between the upstairs and downstairs.

What Do I Do to Fix a Hot/Cold Upstairs?

If your upstairs is hotter or colder than the rest of your residence, an HVAC zoning system could be an 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 very effective in situations where the upstairs of a multi-story home is quite hot or too cold while the main floor is comfortable. By setting up 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 challenge in multi-floor homes is when the upstairs is more humid than downstairs.

A common explanation for excess upper floor humidity is inadequate ventilation on the upper floor, which can cause increased 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. In addition, if there are any leaks or plumbing issues on the upper floor, that can also cause excess moisture in that area of a home.

To correct humidity problems, homeowners can increase ventilation by installing 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. Finding 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 helpful tool to reduce humidity in the residence.
