Busting Air Conditioner Myths

April 14, 2025


Discover the truth behind common air conditioner myths. Learn why lower thermostats don't mean faster cooling, closing vents doesn't save energy, and bigger units aren't always better.

Misunderstandings about how air conditioners work can lead to inefficiency and higher energy bills. Here, we address some common misconceptions about air conditioners.

Myth 1: Lower Thermostat = Faster Cooling

Setting the thermostat to a lower temperature won't cool your home faster. Air conditioners cool at a constant rate, regardless of the thermostat setting. Lowering the thermostat too much can lead to excessive energy use and increased wear on the system. Instead, set the thermostat to your desired temperature and let the AC work efficiently.

Myth 2: Closing Vents Saves Energy

Closing vents in unused rooms does not save energy. It can cause your air conditioner to work harder. Central AC systems are designed to cool the entire house, and closing vents disrupt the balance, leading to increased duct pressure and potential leaks. It’s more effective to use a zoned HVAC system for targeted cooling.

Myth 3: Bigger Units are Better

A bigger air conditioner is not always better. Oversized units cool the space too quickly, resulting in short cycling. This leads to inefficient operation, higher energy bills, and insufficient dehumidification. Choosing the right size unit is important based on your home’s specific needs. A professional HVAC contractor can perform a load calculation to determine the optimal size for your home.
