However, with the increasing popularity of ACs, several myths and misconceptions have also emerged. In this blog post, we aim to debunk some of the most common air conditioning myths to help you make informed decisions and ensure the optimal performance of your cooling system.

Myth 1: Leaving the AC on all day saves more energy than turning it off

One of the prevailing myths about air conditioning is that it saves more energy if you leave it on all day, even when you’re not at home. However, this is not true. Leaving the AC on unnecessarily only leads to wasted energy and increased electricity bills. It is more energy-efficient to turn off the AC when you’re away and turn it on upon your return. Utilize programmable thermostats that allow you to set specific temperatures and schedules that align with your daily routine to optimize energy consumption.

Myth 2: Lowering the thermostat setting cools the home faster

Many people believe that setting the thermostat at a much lower temperature than desired will cool the room faster. However, this is nothing but a myth. Air conditioners work at a constant speed, regardless of the temperature set. Lowering the thermostat only prolongs the running time of the AC, wasting energy and straining the system. Instead, set the thermostat at your desired temperature and be patient. The room will cool down gradually, ensuring optimal energy usage.

Myth 3: Ceiling fans cool the room, so AC isn’t necessary

Ceiling fans are indeed useful in circulating air and creating a breeze-like effect, making you feel cooler. However, it’s important to note that ceiling fans do not actually cool the room. Fans simply provide the perception of cooling by evaporating moisture from your skin, which makes you feel cooler. Air conditioning, on the other hand, actively removes heat from the room, resulting in a significant temperature drop. A combination of both AC and ceiling fans working together can create a comfortable and energy-efficient cooling environment.

Myth 4: ACs only need maintenance when they malfunction

Another misconception regarding air conditioning is that regular maintenance is unnecessary until the system malfunctions. This couldn’t be further from the truth. Routine maintenance is crucial to ensure the optimal performance and longevity of your AC. Neglecting regular servicing can lead to reduced efficiency, higher energy consumption, and even costly repairs. Schedule annual maintenance checks, including cleaning filters, checking refrigerant levels, and inspecting coils, to keep your AC running smoothly throughout the summer.

Myth 5: Closing vents in unused rooms saves energy

A common misconception is that closing the vents in rooms that are not in use will save energy. However, this practice can actually be detrimental to your cooling system and energy consumption. Modern air conditioning systems are designed to operate optimally when all vents are open and unrestricted. Closing vents can disrupt the balance of airflow, causing your AC to work harder and potentially leading to frozen coils or system malfunctions. Instead of closing vents, consider utilizing zoning systems or adjusting the thermostat in unused rooms to maintain an efficient cooling system.


Understanding the truth behind common air conditioning myths is essential for maintaining an energy-efficient cooling system and avoiding unnecessary expenses. By debunking these misconceptions, we can make more informed decisions when it comes to using and maintaining our air conditioning systems. Remember to turn off your AC when not in use, keep the thermostat set at the desired temperature, and schedule regular maintenance to ensure optimal performance throughout the summer. Stay cool and enjoy the sunny season without falling victim to air conditioning myths!
