As temperatures rise during the sweltering summer months, homeowners across the US are turning to their trusty air conditioners for some much-needed relief. However, despite the widespread reliance on these cooling systems, there’s an abundance of misconceptions surrounding their usage and efficiency.

In this blog post, we’ll debunk four common myths about air conditioning units that may be affecting your comfort and wallet. By separating fact from fiction, you will be better equipped to maximize your AC’s performance while ensuring optimal home comfort throughout the season.

Does your AC need to be repaired or replaced? If so, you shouldn’t try to take on the task by yourself; instead, you can contact a reputable HVAC company by clicking the following link:

Common Misconceptions About Air Conditioners

There are several common misconceptions about air conditioners, including the belief that lowering the thermostat as much as possible will cool your home faster and that bigger AC units perform better.

AC Myth #1 — Lowering The Thermostat As Much As Possible Will Cool Your Home Faster

One common misconception among homeowners is that drastically lowering the thermostat setting will speed up the cooling process of their homes. In reality, air conditioners work at a constant rate to cool down indoor spaces until they reach the desired set temperature.

For instance, if your home’s current temperature is 80ºF and you want it to be comfortably cooled to 75ºF, setting your thermostat down to 60ºF won’t make it happen any sooner than just programming it for precisely what you wanted: 75ºF.

This practice can lead to unnecessary wear and tear on your AC system as well as increased electricity consumption which ultimately results in higher utility bills.

AC Myth #2 — More Efficient AC Automatically Saves Money

One common misconception homeowners have when it comes to air conditioning is the belief that a more efficient AC will automatically save them money.

For example, suppose you have an inefficient AC unit but keep your home well-insulated and set the thermostat appropriately for the temperature outside. In that case, you’ll likely see lower energy bills than someone with a highly-efficient AC unit but poor insulation or incorrect thermostat settings.

AC Myth #3 — Bigger AC Units Perform Better

One common misconception about air conditioners is that bigger units perform better. However, choosing an oversized unit can actually lead to energy waste and higher bills.

An AC unit that is too big will cool your home too quickly, causing it to turn on and off frequently, which wastes electricity and wears out the equipment faster. On the other hand, a properly-sized AC unit runs longer but more efficiently, achieving optimal humidity levels and providing consistent cooling throughout your home.

AC Myth #4 — Air Conditioning Causes Colds

It is a common belief that air conditioning can cause colds, but this is a myth. Viruses cause colds, and while being in cooler temperatures may lower our immune system’s ability to fight off these viruses, it doesn’t directly cause them.

Air conditioning can help improve indoor air quality by filtering out allergens and pollutants. However, if your AC isn’t properly maintained or cleaned regularly, it could harbor mold or bacteria, worsening asthma or allergies.


In conclusion, it’s essential to understand the reality of air conditioning and dispel these common misconceptions. Lowering the thermostat won’t necessarily cool your home faster, and bigger AC units do not always perform better.

Efficiency alone doesn’t determine savings, and cold air doesn’t cause sickness. If you want to maximize the performance of your AC unit, proper sizing is crucial, as well as regular maintenance and strategic temperature management.

By doing so, you can enjoy a comfortable home during summer without sacrificing energy efficiency or breaking the bank on utility bills.
