Busting 7 Common Air Conditioning Myths You Probably Still Believe
When it comes to air conditioning, there’s a lot of misinformation floating around. Some of it sounds logical, but believing these myths could be costing you money, comfort, and energy efficiency.
Let’s set the record straight by busting 7 common AC myths once and for all:
🔌 1. “Turning off the AC when I leave saves more energy.”
Not always.
Turning your system off completely can make your home overheat, which means your AC will work harder when you turn it back on. A better solution? Use a programmable thermostat to adjust the temperature while you’re away.
❄️ 2. “The lower I set the temperature, the faster it cools.”
False!
Air conditioners work at a constant speed. Setting it to 60°F won’t cool your room faster — it’ll just overwork your system and waste energy.
🚪 3. “Closing vents in unused rooms saves energy.”
Nope.
Closing vents can cause pressure imbalances in your system, making it less efficient and potentially damaging over time. It’s better to use a zoned system if you want room-by-room control.
🧼 4. “My AC doesn’t need maintenance if it’s working fine.”
Big myth!
Like any machine, regular maintenance helps your AC run better and last longer. Dirty filters, coils, or leaks can silently reduce efficiency and shorten the system’s life.
🌬️ 5. “Ceiling fans cool the room.”
Not exactly.
Fans don’t lower room temperature — they move air to help you feel cooler. Turn them off when you leave the room to save energy.
🧊 6. “Bigger AC units cool better.”
Actually, bigger isn’t always better.
An oversized unit will cool the space too quickly without removing enough humidity. This can lead to a clammy, uncomfortable environment and high energy bills.
🏡 7. “All AC systems are the same.”
Nope — today’s AC systems range from basic models to smart, ultra-efficient, inverter-driven units that can slash your energy bills. Choosing the right system matters!
