6 Common Myths About Air Conditioning: Debunking Misconceptions


In the scorching heat of summer, air conditioning systems play a crucial role in keeping us comfortable, safe, and healthy. However, despite their presence in our lives, there are numerous myths and misconceptions surrounding air conditioning systems that persist. As your trusted HVAC experts, we’re here to debunk some of these common myths and provide you with accurate information to ensure you get the most out of your AC system.

Myth 1: Lowering the Thermostat Cools the Room Faster

One of the most prevalent myths about air conditioning is the belief that setting the thermostat to a lower temperature will cool the room faster. Adjusting the thermostat to extreme settings can actually lead to excessive energy consumption and unnecessary strain on your AC system, resulting in the need for AC repair in Santa Ana. Instead, we recommend setting your thermostat to a comfortable temperature and allowing the system to work efficiently.

Myth 2: Closing Vents in Unused Rooms Saves Energy

It’s a common misconception that closing vents in unused rooms can help save energy and improve the efficiency of your air conditioning system. However, closing vents can cause the air conditioner to work harder to compensate for the restricted airflow, resulting in higher energy bills and premature wear and tear on the equipment. 

Myth 3: Bigger AC Units Are Always Better

Many homeowners believe that installing a larger air conditioning unit will provide better cooling performance. But when an AC system is too large for the space it’s cooling, it tends to cycle on and off more frequently, leading to increased energy consumption, higher humidity levels, and uneven temperatures throughout your home. 

Myth 4: Air Conditioners Only Cool the Air

While air conditioners are primarily designed to cool the air, they also play a vital role in dehumidifying indoor spaces. As warm air passes over the evaporator coil inside the AC system, moisture condenses and is removed from the air, resulting in lower humidity levels. This not only enhances comfort but also improves indoor air quality by reducing the risk of mold and mildew growth. 

Myth 5: Regular Maintenance Isn’t Necessary for AC Units

Neglecting routine maintenance can lead to a variety of issues, including reduced efficiency, higher energy bills, and costly air conditioning repairs down the line. By scheduling annual maintenance visits with our Certified Technicians, you can ensure that your AC system is operating at peak performance and identify any potential problems.

Myth 6: Turning Off the AC When You’re Away Saves Energy

Some homeowners believe that turning off the air conditioning when they’re away from home is an effective way to save energy and reduce their utility bills. However, this can actually result in higher energy consumption and increased wear and tear on the system. Instead of turning off the AC entirely, consider raising the temperature by a few degrees.
