Why Are Some Rooms In My Home Hotter Than Others?

A room with many windows benefits from natural light but can also trap heat. If this room is consistently hotter, using blinds or curtains to minimize sunlight exposure can help regulate the temperature. Additionally, considering window treatments with reflective properties or adding window film can further reduce heat gain.

Having an AC system that is too small for your home size can lead to some areas being neglected. If your AC system is too small, it won’t be able to distribute cool air evenly, leading to hot spots.

If this is the case, it would be helpful to speak with an HVAC specialist about purchasing a more fitting unit for your home.

The location of your thermostat is what dictates how your AC will cool your home. Your thermostat measures the temperature of the area surrounding it. When you set a certain temperature for your home, the duration your AC runs is dictated by this surrounding area.

So, if you live in a three-story home and your thermostat is on your main floor, it can result in your upstairs area having a much higher temperature.

Although this one may seem obvious, sometimes the simplest answer can be the right one. It is best to ensure that the vents in your problem room(s) are fully open and not obstructed.

The obstruction could result from full coverage from clothing or furniture, or partial coverage can dampen the effectiveness of your system.

One issue that many homeowners may run into is that old and or poorly insulated windows can result in outside heat seeping into your home. This could be an issue that only occurs in one or two rooms within your home, resulting in a higher temperature there.

A great way to tell if your windows are poorly insulated is to check for a draft or dramatic temperature change in the area near the window. If you can feel either of these, it may be time to replace your windows.

One problem that can lead to some rooms having a higher temperature than others is an imbalance in your cooling system. Multiple factors can cause an imbalance in your system. Two common ones homeowners encounter are a missized AC system or closing vents.

An AC system that is too large can send bursts of air into your home and then turn off. This type of operation can create an imbalance in the home where some rooms are getting cooled quickly and others are neglected.

The other common issue, vents being closed, is one many homes may run into. Homeowners may close vents in rooms they do not use as often to save money. However, doing this can cause a change in the home’s airflow and thus create an imbalance in your AC system that impacts the temperature of some areas in the home.

If you have a room that is running hot, it is important to consider what the purpose of that room is. For example, if you have a home office that has monitors and a desktop computer, the room is going to use more energy and give off more heat. This will cause the room to feel hotter than other areas in the home.
