Even a premium fan can’t effectively cool a space in some instances, leaving you wondering, “Why is my fan blowing hot air?” Fans do not provide the active cooling of an air conditioning unit, but the airflow can help lower indoor temperatures. While adjusting your speed and thermostat settings might help, fans can struggle to cool your core temperature. Read on to learn more about this problem.
KEY TAKEAWAYS:
While fans don’t have the extra power of air conditioner service, they can help remove excess heat if you utilize proper placement and fan settings to maximize your indoor comfort. Compare the Vornado 533 vs 633 to understand the types of fans that will help cool your home.
Insider Tip
Place your fan in a shaded window to intake cool air, and use an outward fan in a sunny window to exhaust warm air.
That said, if the indoor and outdoor temperatures are too high, a fan’s evaporative effect might not be able to dissipate your body heat effectively. Additionally, a burnt-out fan motor will make a nasty noise and halt the cool wind from your fan, so you’ll need to learn why your ceiling fan is making noise to ensure proper operation.
Fan placement is a critical factor in ensuring a refreshing breeze. Since hot air rises, you can utilize a tall window to exhaust warm air from your home. Additionally, you can use a window fan to intake cool air from a ground-level, shaded window. Use multiple fans to cycle fresh, cool air into your home and expel hot air. This cross-breeze will keep your fans from simply moving around ambient heat.
Warning
Never operate on your ceiling fan’s wiring system without disconnecting it from the circuit breaker.
You can change the rotation direction of most ceiling fans, enhancing the recommended air movement for the season. In the summer, you want a counterclockwise ceiling fan to push a breeze around the room. In the winter, you need a clockwise rotation to push warm air from the ceiling and toward your family. This is especially important in a baby’s room, as fans may help prevent SIDS.
A portable fan with a washable filter can become congested by dirt, grime, and dust. With restricted airflow, your fan cannot push enough air for a cooling breeze. You can clean or replace the filter to optimize the air movement from the fan unit.
STAT: A 2020 US EIA (Energy Information Agency) survey showed that 18.6% of Americans keep their central air conditioner at 69 degrees or less during summer daytime. (source)
