How to Cool Down a Hot Room

The various rooms in a home may have fluctuating temperatures. On a scorching summer day, some rooms become hotter than others, prompting the homeowner to try to cool it down. Here are ways to cool down a room in the home that feels hotter than the rest.

Why is the bedroom hotter than other rooms?

A bedroom can be hotter than the rest of the house. When this occurs, perform an investigation. The answers to two questions can point to a solution. Troubleshoot the problem of a hot room by determining whether or not it is due to solar heating issues.

Is the bedroom warmer than the rest of the home year-round? If so, then the sun is responsible for keeping that room uncomfortably warm, especially in summer. The second question to answer is whether the bedroom is hot in summer and cold in winter.

If this is the case, then the air ducts may be undersized, thereby failing to deliver cool air in the summer and warm air in the winter. Increasing the size of the air ducts is a practical solution. Alternately, add a booster fan so that the cool and warm air can reach the distant bedroom.

Plus, hot air rises. When the bedroom is located on the upper floor, it will inevitably be hotter in summer than other rooms in the home. This is especially the case when the home is built with one HVAC unit that serves a two-story home.

Why does a room remain hot with the window open?

Rooms may remain hot despite the window being open. On hot, humid days, the outside warm air enters the home through the open window, and the cooler, inside air travels outside. Due to this reason, keeping the window open on a hot day makes the inside temperatures even worse.

Why does a room remain hot with the fan on?

Fans, especially small ones, fail to sufficiently add a blast of chilled air to a hot room. A running fan simply circulates air—it does not cool it. A large ceiling fan, however, can push cool air downward in the room when the blades spin counterclockwise.

How is a hot room cooled down?

Cooling down a hot room is not only doable but recommended. Mold growth can develop when rooms remain hot and humid. Spores thrive wherever moisture and an organic food source, like drywall, are abundant. Here are easy ways to keep any part of the home cool.

1. Tint Windows

A hot room can become cooler with a few proactive measures. Since the room that faces the sun will be the hottest, it is recommended that the windows to this part of the home be tinted. Also install heat-blocking blinds in the room that has the most sun exposure.

2. Replace Thermostat

Consider installing a thermostat that senses humidity as well as temperature. A humidity-sensing device gauges the temperature in all rooms, not just the living room in which it is located. Replace the current thermostat with one that features wireless remote room sensors.

3. Plant Trees

Plant trees and shrubs outside the rooms that receive the most sun exposure. Natural vegetation can provide sufficient shade and serve to cool the hottest rooms. Choose trees that lose their leaves in winter so that the sun’s rays warm up the room during the cold season.

4. Change Air Filters

Dirty filters obstruct airflow. Homeowners who intend to cool down their home simply need to change the filters regularly. Carefully select the air filter, as allergy filters are highly restrictive. Designed to capture microscopic allergens, they work to clean the air but impede airflow.

5. Inspect Vents

Check the vents in the home to make sure furniture, drapes, and other household goods do not block them. Drapes partially hanging over a vent can obstruct the flow of cool air into the room. Similarly, desks, bookcases, or ottomans may be inadvertently positioned over the vent, blocking it.

6. Relocate Electronics

Numerous electronics can heat up a room, causing it to become hotter than other parts of the home. If a particular room becomes hot and is filled with a Wi-Fi router, printer, and stereo receiver, move some of them to other locations, like a basement or a crawlspace.

7. Leave Doors Open

An evenly air-conditioned home can also be achieved by cracking the door open whenever possible. By keeping the door open, both during the day and night, air flows evenly to and from the room. Make sure the room does not contain a return air grille (not just the register).

A hot room is not only uncomfortable, but it can spread mold. Air holds more water at higher temperatures, so it’s important to keep rooms in the home cool when the summer temperatures and humidity are at high levels. If mold develops, consult ServiceMaster Fire & Water Cleanup.

Mold infestations occur when the indoor environment contains excess moisture. Mold is a serious threat to the property, as the colonies can eat away at organic materials and cause severe damage. Health problems can develop in building occupants who are sensitive to mold.
