Debunking the Common AC Myth


When it comes to air conditioning (AC) systems, there are numerous myths and misconceptions that circulate, leading to inefficient usage and potential damage. In this blog post, we’ll tackle one of the most prevalent myths and shed light on the truth.

The Myth: Setting the thermostat to a Lower Temperature Cools the Room Faster

Many homeowners believe that lowering the thermostat to an extremely low temperature will cool their living space more rapidly. However, this is a myth that needs to be debunked.

The Reality

  • Your AC system is designed to cool at a specific rate, determined by its capacity and efficiency.
  • Setting the thermostat to a lower temperature does not make the AC unit work harder or faster.
  • Instead, it will continue to cool at the same rate until the desired temperature is reached, and then it will cycle on and off to maintain that temperature.

The Consequences of This Myth

Believing this myth can lead to several consequences, including:

  • Increased energy consumption, resulting in higher utility bills.
  • Unnecessary stress on the AC system, potentially leading to premature wear and tear.
  • Uncomfortable temperature swings as the system struggles to maintain the unrealistic temperature setting.

The Recommended Approach

To ensure optimal performance and energy efficiency, it’s best to follow these guidelines:

  1. Set the thermostat to a comfortable temperature, typically around 72°F to 78°F (22°C to 26°C).
  2. Allow the AC system to cool the space gradually and consistently.
  3. Regularly maintain your AC unit by scheduling professional tune-ups and cleaning.


Debunking myths and misconceptions is crucial for ensuring the proper usage and maintenance of your AC system. By understanding the realities of how your AC operates, you can save energy, reduce utility costs, and extend the lifespan of your unit. Remember, setting a lower temperature on the thermostat won’t cool your home faster, but it will lead to inefficiencies and potential problems.
