Commercial air conditioning systems are the backbone of any comfortable business environment, providing cool air during hot summer days and maintaining optimal indoor air quality. However, a surprising number of myths persist about how these systems work and how best to use them. These misconceptions can lead to inefficient practices, higher operational costs, and a shorter lifespan for your HVAC system.
As experts in commercial HVAC systems with years of hands-on experience, we at TJ Refrigeration believe it’s time to clear up the confusion. In this article, we’ll debunk the most common commercial air conditioning myths, ensuring you’re better informed and able to make smart decisions for your business.
Myth 1: Bigger AC Units Are Always Better
When it comes to commercial air conditioning, bigger isn’t necessarily better. Many believe that a larger unit will cool a space faster or more effectively, but oversized units can cause more harm than good.
Why? Oversized units will frequently cycle on and off, which wastes energy and reduces the lifespan of your equipment. Moreover, they fail to dehumidify the air properly, which can leave your business feeling damp and uncomfortable. Proper sizing is essential, and this is where professional advice becomes invaluable. At TJ Refrigeration, we use precise calculations to ensure the right fit for your business’s needs.
Myth 2: Turning Off the AC When Not in Use Saves Money
This myth is especially popular in offices and commercial spaces, where people believe turning off the system when the building is empty will save energy. While it’s true that turning off your AC will temporarily cut energy consumption, constantly powering it down and back up can actually be less efficient.
When you restart your system, it works harder to bring the indoor temperature back to a comfortable level. This process consumes more energy than maintaining a consistent temperature. Instead, consider a programmable thermostat or energy-saving mode that keeps your system running efficiently without the heavy start-up costs.
Myth 3: Air Conditioning Only Cools the Air
Many people think air conditioning systems are only responsible for cooling indoor air, but they also play a critical role in improving air quality and controlling humidity. This is particularly important for businesses where product quality and staff comfort are paramount, like restaurants and healthcare facilities.
A well-maintained AC system will filter out pollutants, allergens, and dust, which can improve air quality and reduce the risk of respiratory issues. It also controls humidity, preventing mould growth and maintaining a healthy work environment.
Myth 4: All Air Conditioning Systems Are the Same
Not all commercial AC systems are created equal. Depending on your business, building structure, and specific cooling needs, the right system for you could be vastly different from the one installed in another company down the street.
Options include central air, split systems, and ductless systems, each with its own advantages and disadvantages. Choosing the wrong type can result in inefficiency and higher costs. Consulting with an expert, like the professionals at TJ Refrigeration, is crucial in selecting the best system for your commercial space.
Myth 5: Maintenance Is Not Necessary If the System Is Running Fine
“Why fix something that isn’t broken?” This thinking is common but costly. Regular maintenance of your commercial air conditioning system is vital to ensure it runs efficiently and lasts as long as possible.
Over time, dirt, dust, and debris accumulate in filters and coils, reducing the system’s efficiency and increasing energy bills. A neglected system will also be more prone to breakdowns, leading to expensive repairs. Routine inspections by professionals, like those offered by TJ Refrigeration, can spot small issues before they become major problems.
Myth 6: Closing Vents in Unused Areas Saves Energy
It may seem logical that closing vents in unused rooms will save energy by redirecting cool air where it’s needed. However, closing vents can actually disrupt the system’s airflow, causing it to work harder and reduce its overall efficiency.
Commercial HVAC systems are designed to distribute air evenly throughout a building. Blocking vents increases pressure in the ducts, leading to air leaks and reduced system performance. The key to energy savings lies in maintaining proper airflow, not blocking it.
Myth 7: You Can Install a Commercial AC System Anywhere
Proper installation is crucial to an air conditioning system’s performance. Some believe that a commercial AC system can be installed anywhere without much thought. In reality, the system’s placement has a significant impact on its efficiency and lifespan.
Placing the outdoor unit in a shaded, well-ventilated area can improve performance, while poorly placed units may overheat or fail prematurely. This is why installation should always be handled by professionals who can ensure your system is optimally located for maximum efficiency.
Myth 8: Commercial ACs Are Too Expensive to Run Efficiently
Modern commercial AC systems are more energy-efficient than ever before. While it’s true that running an air conditioning system incurs costs, advancements in technology have made it possible to operate them without breaking the bank.
Investing in a high-efficiency unit, like those recommended by TJ Refrigeration, and employing smart energy-saving practices—like regular maintenance, programmable thermostats, and optimised airflow—can drastically reduce your operating costs.
Myth 9: Setting the Thermostat Lower Cools the Space Faster
Setting the thermostat to the lowest possible temperature won’t cool your building faster. Commercial AC systems work at a consistent rate, regardless of the temperature setting.
What actually happens is that the unit runs longer, overcooling the space and using more energy. The best approach is to set the thermostat to the desired temperature and let the system do its job.
Myth 10: Commercial Air Conditioning Systems Cause Illness
A common misconception is that air conditioning spreads illness, but a well-maintained system can actually improve health by filtering out allergens, pollutants, and bacteria from the air.
However, neglected systems with dirty filters or poorly cleaned ducts can circulate dust and other harmful particles, leading to respiratory issues. This is why regular maintenance, such as air filter replacements and duct cleaning, is so important. At TJ Refrigeration, we offer services that ensure your system supports a healthy environment for everyone in the building.
Myth 11: Duct Cleaning Is Not Necessary
Dirty ducts can significantly impact your commercial AC system’s efficiency. Over time, dust and debris accumulate, restricting airflow and making your system work harder to cool the building. This leads to higher energy costs and puts unnecessary strain on the system.
Regular duct cleaning ensures that your system operates at peak efficiency and improves air quality by removing harmful particles. This is a service we strongly recommend for all commercial buildings.
Myth 12: Air Filters Only Need to Be Changed Once a Year
Air filters play a critical role in maintaining both air quality and system efficiency. Depending on the environment, especially in commercial spaces with high traffic, filters may need to be replaced every 1-3 months.
Failing to change air filters regularly can lead to poor indoor air quality and increased strain on your system, resulting in higher energy bills and frequent breakdowns. Our team at TJ Refrigeration recommends scheduling filter changes as part of your regular maintenance plan.
Myth 13: It’s Cheaper to Repair Than Replace an Outdated System
While repairs may seem cheaper in the short term, constantly fixing an old, inefficient system can quickly become more expensive than simply replacing it with a newer, energy-efficient model. New systems not only perform better but also consume less energy, saving you money in the long run.
If your commercial AC system is over 10-15 years old and frequently requires repairs, it may be time to consider an upgrade. At TJ Refrigeration, we help businesses weigh the cost-benefit of repair versus replacement.
Conclusion
Understanding the truth behind common air conditioning myths can help you make informed decisions about your commercial AC system, saving you time, energy, and money. From proper sizing to regular maintenance, the small details make a big difference in your system’s performance and longevity. At TJ Refrigeration, we are here to ensure your air conditioning system operates at its best, providing comfort, efficiency, and cost savings for your business.
