Common Myths About Air Conditioning Debunked

by | Oct 18, 2024 | Air Conditioning

Air conditioning (AC) is a prominent part of modern comfort that transforms your living conditions during excessive summer heat. Despite its widespread usage, misconceptions and myths surrounding this technology can result in inefficient operations and higher costs, negatively affecting the overall user experience. For instance, some believe that turning the thermostat down lower will cool the room faster, while others think air filters only need cleaning once a year. These myths not only mislead users but also hinder their ability to take advantage of energy-saving features, like programmable thermostats and proper insulation.

This blog aims to reveal the most common myths about air conditioning units, to provide a clearer understanding, and to promote responsible usage for improved comfort.

What are the Common Myths About Air Conditioning?

Myth 1: Air Conditioners Spread Germs

The most persistent myth is that an air conditioner spreads germs and airborne diseases. It arises from a lack of understanding of how an air conditioning unit works. In reality, a properly maintained air conditioning unit helps reduce the proliferation of germs and allergens in the air. 

Most modern AC units have filters that efficiently capture airborne contaminants and ultraviolet (UV) light technology that eliminates pathogens (including viruses and bacteria). This light technology exposes microorganisms to UV radiation, rendering them inactive and preventing them from reproducing.  

Myth 2: Air Conditioners Inject Cold Air into Your Home

An efficient system works through the heat exchange process, using refrigerants to absorb and expel heat. This means that when an AC unit operates, it draws the warm air from the room through its return vents, which are circulated over the evaporator coils. These coils are filled with refrigerants that evaporate at low temperatures (absorb heat and lower humidity levels), and in the process cool the air, which is circulated back into the room via supply vents. 

This process is often misunderstood as the injection of cold air, making it one of the common air conditioning myths. These units are designed to balance the temperature rather than inducing cool air.

Myth 3: Outdoor Units Can Be Installed Anywhere 

The outdoor units, i.e., the condensers cannot be installed anywhere on your property as it can affect your air conditioner’s performance and lifespan. These units require sufficient airflows to function properly, which is why placing them in an enclosed space causes your system to overheat. It happens when the airflow is restricted, and your unit works harder to cool your space. To prevent this, you must install outdoor units in an open area, i.e., away from walls and fences, for better ventilation. Most manufacturers suggest a clearance of at least two feet around the unit and five feet above to ensure complete air circulation. Installing these units in a shaded, cooler area enhances their performance and reduces the strain on the condenser. 

Besides this, noise is another reason outdoor units can not be installed anywhere. These units can be loud, so placing them too close to patios, bedrooms, or living areas may cause disturbances. In these cases, experts recommend positioning them away from high-traffic areas or behind a noise barrier to reduce disturbances.  

Myth 4: Quick Cooling by Turning Down the Temperature 

Lowering the thermostat to a cooler setting does not cool the room faster, as air conditioners operate at a constant speed regardless of the temperature. These units are designed to remove heat from air at a consistent rate, which means that whether your thermostat is set at  72°F or 60°F, it will take the same amount of time to cool the room. 

It helps you realize that turning the thermostat down to an extreme level can cause the system to run longer until it reaches the desired temperature. This reduces its efficiency and increases higher energy costs. Additionally, It is suggested to keep it at a moderate or comfortable temperature (around  72°F to 75°F), allowing your unit to cycle on and off efficiently. 

Myth 5: Consistent Thermostat Temperature Setting Saves Money

Setting your thermostat to a fixed temperature leads to unnecessary energy consumption. Air conditioners are designed to work their hardest when cooling your space, but leaving them at the same temperature simply means that your system never gets a break. To save money, adjusting the thermostat as per your routine seems more effective.

Further, AC units operate more efficiently when running in short bursts instead of constantly working to maintain a fixed temperature. Allowing your space to warm up slightly during periods of low activity and cooling it down only when needed reduces the overall strain on your air conditioning system.

Myth 6: Air Filters Only Need to Be Cleaned Once a Year

One of the most prevalent myths about AC filters and maintenance is that the air filters only need to be cleaned or replaced once a year. This misconception can lead to inefficient cooling. Air filters are designed to trap dirt, dust, pollen, and other airborne particles, but over time, these particles can accumulate, clogging the filters. This forces the system to push the air through, resulting in premature wear, overheating, and costly repairs. 

For this, experts suggest cleaning or replacing air filters every 1-3 months, depending on the type of filter, frequency of AC use, and level of indoor air pollution. 

Final Word

Common myths about air conditioning, such as neglecting regular air filter replacements, setting the thermostat extremely low for faster cooling, and more, can lead to premature system breakdowns. This is why proper knowledge is crucial for debunking these misconceptions and ensuring better performance and longevity of your AC units. Beyond these myths, it is also crucial to understand that air conditioners require consistent care, regular tune-ups, and timely maintenance to prevent system strain. Therefore, it’s essential to seek air conditioner repair near you for expert guidance.
