Sunlight exposure If your bedroom has lots of windows and is pounded by the sun, heat can become trapped inside and push up the temperature. You can battle the sunlight by installing blinds and curtains (either standard or blackout), and keeping them closed during the day.
Faulty Return Air Vents
So, if one room is always warmer than the rest of your home, the return air vents in the room could be blocked or damaged. When this occurs, cool air is blocked from coming through those vents in your floor or ceiling, resulting in a less comfortable space.
Closed vents—Closed vents in rooms can cause them to be hotter than other rooms. Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home. Air duct issues—If you have any kinked or crushed supply ducts, certain rooms won't get enough air.
A smart alternative would be a ductless air conditioner. Also known as a mini-split AC, these systems are ideal for cooling down a specific room, especially one that's much hotter than the rest of the house.
If you have closed your air vents, or your vents are obstructed by furniture or upholstery, proper airflow is being disrupted. This can most certainly cause some rooms in your home to be hotter than others, while placing extra strain on your HVAC system.
Look around to see if you have any blocked or dirty vents. Your vents and your registers can contribute to uneven cooling if they're blocked by furniture or anything else. This can also happen if dust and debris builds up on them. You can vacuum them with an attachment to loosen and remove the debris.
Your Vents Are Blocked
Your thermostat will not be able to reach your desired temperature if you have something blocking the vents. Check the vents around your home and make sure you do not have any items such as furniture in the way of your vent's airflow. While you're at it, make sure all of your vents are open.
Perhaps the most common cause of AC issues is clogged filters. Dirt, pet hair, pollen and dust can clog your filters. When filters get clogged, they begin to restrict the flow of air through your AC. The result is that the AC doesn't cool your indoor air effectively.
A ceiling fan does not actually lower the overall temperature in a room, but it can definitely make a space feel cooler. Ceiling fans primarily work through something called a wind chill effect. Essentially, the moving air across your skin helps to evaporate sweat at a faster rate.
In general, it's best to keep your interior doors open as often as possible in order to allow air to flow freely from room to room. This will avoid pressure problems in your home and will make it easier for your air conditioner to cool your home evenly and with less energy.
The rule you should go by is whether it is hotter outside than inside. If the temperature is higher outside than it is inside, you should keep your windows and curtains closed. This will shut the heat out, and help to keep your home cool.
Benefits of Natural Ventilation
By opening windows to let that fresh air in, you can improve your indoor air quality. Opening two windows on opposite sides of a room provides a cross breeze, letting the bad air out and the good air in.
How often should you air out your house? You should air out your house every day for around 15 to 30 minutes a day. Always air out your apartment when you're painting or doing other renovations in the home. If you're frying, grilling, or cooking for a lot of people, make sure to turn your range hood on.
Heat intake during these nights comes from things like wind blowing into windows or cracks beneath doors (wind speeds increase significantly at night), warm air passing by your skin (air temperatures are typically higher nearer to the ground), and hot objects within rooms like lights, electronics, appliances (some ...
The distance a room is from the system can have a big impact on temperature. As you get further and further from your HVAC system, there is air flow loss. Rooms at the furthest point may not be as warm or cool as the rooms much closer to the system.
For example, a room that faces the sun most of the day will naturally be warmer than one facing away from it. If you live in a particularly warm or cold place, the number and size of the windows in a given room — as well as how those windows are sealed — can affect the overall temperature.
Adjusting supply registers in rooms is the most accessible method of minimizing airflow into one room. Partially or completely closing supply registers reduces system airflow into that room alone, and also reduces airflow into the room return duct.
ASHRAE (formerly called the American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends (in its Standard 62.2-2016, "Ventilation and Acceptable Indoor Air Quality in Residential Buildings") that homes receive 0.35 air changes per hour but not less than 15 cubic feet of air per minute (cfm) per ...
