An air conditioner is essential for comfort during hot weather—but where you install it can make a big difference to your family’s health. Many households unknowingly place their AC units in the wrong spots, leading to poor air circulation, uneven temperatures, and even health problems like respiratory issues, headaches, or fatigue.

Before you mount that unit, here are 4 locations to avoid if you want to keep your family safe and healthy:

---

1. Directly Above the Bed or Sofa

Placing an AC unit right above where you sleep or rest might feel convenient—but it’s not. Cold air blowing directly on your body for hours can cause stiff muscles, dry skin, sore throats, and even sinus issues. Instead, install the unit so it cools the room evenly without blowing directly on people.

2. Opposite a Door or Window

While it may seem logical to face the AC toward an opening, this setup often leads to air escaping and uneven cooling. The unit will work harder, using more electricity, and may not cool the room properly. Over time, this can lead to fatigue, temperature fluctuations, and even weakened immunity.

---

3. In a Corner or Enclosed Space

Don’t install the air conditioner in a cramped corner or behind a partition. It will trap the airflow, making the room feel stuffy and forcing the unit to overwork. Poor ventilation also increases the risk of mold and bacteria buildup, which can cause allergies or respiratory issues.

4. Near Electrical Appliances or Heat Sources

Avoid placing your AC near TVs, refrigerators, or heat-emitting devices. These appliances trick the thermostat into thinking the room is hotter than it is, causing the AC to run longer and harder than necessary. This not only wastes energy but can lead to overcooling, which isn't healthy in the long term.

Bonus Tip: Regular Maintenance Is Key

Even if your unit is placed perfectly, neglecting regular cleaning and maintenance can turn it into a health hazard. Dusty filters and mold buildup can cause coughing, sneezing, or skin irritation. Clean filters every 1–2 months and schedule professional servicing annually.
