- Utilise reverse cycle systems for year-round comfort.
- Regular maintenance keeps your air conditioner running smoothly and extends its lifespan.
Air conditioning has become an essential part of modern living, but over the years, several myths have taken root, influencing how people use and perceive their cooling systems. Many of these misconceptions can lead to higher energy costs, inefficient performance, or unnecessary strain on your unit. In this guide, we’ll set the record straight on some of the most common air conditioning myths and show you how Midea’s innovative solutions can help you maximise efficiency and comfort.
Myth #1: Leaving Your Air Conditioner on All Day Saves Energy
The Truth:
Many believe that keeping the air conditioner running at a constant temperature all day is more energy-efficient than turning it off and back on. However, running your unit non-stop leads to unnecessary energy consumption and higher electricity bills.
The Midea Solution:
Midea’s Wi-Fi-controlled wall-split systems, integrated with AirTouch, allow you to schedule and remotely control your air conditioner, ensuring it runs only when needed. With smart scheduling and zoning features, you can cool specific areas of your home just before you arrive, reducing energy waste and enhancing comfort.

Myth #2: Lowering the Thermostat Temperature Cools Rooms Faster
The Truth:
Modern air conditioners operate at a fixed cooling rate regardless of the temperature setting. Setting the thermostat to 16°C instead of 24°C doesn’t accelerate cooling—it simply prolongs runtime until the lower temperature is reached, leading to higher energy consumption.
The Midea Solution:
For optimal efficiency and comfort, experts recommend setting your thermostat between 22-24°C. Smart thermostats and zoning systems, like those found in Midea air conditioners, allow for efficient temperature control while reducing unnecessary energy use.
Myth #3: Closing Vents in Unused Rooms Saves Energy
The Truth:
Closing vents in unused rooms may seem like a logical way to cut energy costs, but it can increase pressure in the ductwork, making your system work harder and leading to potential damage or inefficiency.
The Midea Solution:
Midea’s zoning technology in ducted air conditioning systems enables you to control temperatures in different areas of your home without putting unnecessary strain on your system. This way, you can direct cooling where it’s needed most without overworking your unit. Discover the benefits of zoning here.
Myth #4: A Bigger Air Conditioner Provides Better Cooling
The Truth:
An oversized air conditioner will cool your home quickly but won’t run long enough to remove humidity effectively. This can lead to a cold but clammy indoor environment, plus increased wear and tear on your system due to frequent on-and-off cycling.
The Midea Solution:
Choosing the right-sized unit for your space is essential. Midea offers energy-efficient wall-split and ducted systems that provide balanced cooling and dehumidification. If you’re unsure about sizing, check out our guide to choosing the best air conditioner size.
Myth #5: Air Conditioning Spreads Illnesses
The Truth:
Air conditioning itself doesn’t spread illness, but dirty filters and poorly maintained units can circulate allergens and pollutants. Proper maintenance and high-quality air filtration reduce these risks.
The Midea Solution:
Midea air conditioners come equipped with high-density air filters that improve indoor air quality by reducing airborne particles, dust, and allergens. Regular cleaning and maintenance ensure your air remains fresh and clean.
Myth #6: Ceiling Fans Cool Rooms
The Truth:
Ceiling fans don’t lower the actual temperature of a room; they create a wind-chill effect that makes you feel cooler. Leaving fans running in unoccupied rooms wastes energy without providing any real benefit.
The Midea Solution:
For best results, combine ceiling fans with air conditioning. By using fans to improve airflow, you can set your thermostat a few degrees higher while maintaining comfort, reducing overall energy consumption.
Myth #7: Annual Maintenance Is Unnecessary
The Truth:
Skipping regular maintenance can lead to reduced efficiency, higher energy bills, and system breakdowns. Over time, dust and debris can clog filters and coils, forcing your air conditioner to work harder.
The Midea Solution:
Routine maintenance, including filter cleaning and professional servicing, keeps your unit running efficiently. Midea systems also feature self-cleaning functions and diagnostic tools to help maintain peak performance. Read our guide on proper maintenance.
Separating Common Air Conditioning Myths and Facts
| Myth | Reality | Solution |
| Leaving AC on all day saves energy | Running AC non-stop increases energy bills | Use smart scheduling and AirTouch integration |
| Lowering thermostat cools room faster | AC cools at a fixed rate regardless of setting | Set thermostat between 24–26°C for efficiency |
| Closing vents in unused rooms saves energy | Increases pressure in ductwork, reducing efficiency | Use zoning technology instead |
| Bigger AC provides better cooling | Oversized units short cycle and don’t remove humidity effectively | Select the right-sized unit for your home |
| AC spreads illnesses | Poor maintenance, not AC itself, circulates allergens | Regularly clean high-density filters |
| Ceiling fans cool rooms | Fans create a wind-chill effect but don’t lower temperature | Combine with AC for efficient airflow |
| Annual maintenance is unnecessary | Skipping maintenance reduces efficiency and increases costs | Perform routine servicing and filter cleaning |
Frequently Asked Questions
Does turning the air conditioner off when I leave the house save energy?
Yes, turning it off or using smart scheduling helps reduce unnecessary energy consumption and lowers electricity costs.
What is the best temperature setting for energy efficiency?
For cooling, 22-24°C is ideal. In winter, set it to 19-21°C for heating to maintain comfort while saving energy.
How often should I clean my air conditioner filter?
Filters should be cleaned or replaced every 3-6 months depending on usage and air quality.
Is it okay to run my air conditioner all night?
Yes, but using the sleep mode function can help adjust temperatures gradually for better comfort and efficiency.
Are Midea air conditioners environmentally friendly?
Midea uses R32 refrigerant, which has a lower environmental impact compared to older refrigerants. Learn more about R32 refrigerant benefits here.
