No matter how common and useful central air conditioning is in many homes, the equipment still isn’t safe from some money- and energy-wasting misconceptions. In this post, we’ll debunk these popular myths to help you get the best performance from your HVAC system.

MYTH #1: The bigger the air conditioning unit, the better it will cool your home.

The truth is, an oversized unit can create sudden bursts of cold air, fooling the thermostat into shutting the system off before the entire house reaches the intended temperature. A central cooling system that’s sized and installed properly will cycle on and off at various times in order to maintain the temperature setting on the control system. This is better for energy efficiency as well as the removal of stale air.

MYTH #2: Closing vents in an unused room will help save energy.

The practice of closing the vents in rooms that aren’t used regularly may actually do more harm than good and can compromise indoor air quality. Closing the registers in a room that’s not used regularly will put pressure on the central air conditioning unit and could even initiate unwanted leaks in the cooling system. Poor ventilation creates mold and mildew issues, which are harmful to the environment and household occupants.

MYTH #3: You need to turn off the air conditioner when you leave the house. 

It’s understandable to think that turning off your air conditioner when you leave the house will save you more money than leaving it on while you’re away. However, the opposite is actually true. The air conditioner is largely responsible for regulating humidity inside the living space, so if you turn it off and the temperature continues to rise, your system will have to work harder to recover a cool, comfortable home.

MYTH #4: A high-quality, energy-efficient AC unit doesn’t need regular maintenance.

For your central cooling system to achieve and maintain peak performance, routine seasonal maintenance must be observed. Comprehensive, detailed checkups will help identify airflow problems, system leaks and other potential concerns. In this way, any  air conditioning repair services can be a timely manner.
