Are Air Conditioning Myths Costing You More Money?

June 15, 2023

If you’re struggling to keep your energy bills under control during the summers, it's time to debunk some common air conditioning myths that might be costing you more money than necessary. Let's separate fact from fiction and find out how to optimise your cooling system's efficiency without breaking the bank.

Myth 1: Lowering The Temperature Cools The Room Faster

Have you ever cranked down the temperature on your AC, hoping to cool the room faster? Well, it's time to dispel this myth. Lowering the temperature setting doesn't speed up the cooling process; it only makes the AC work longer to achieve the desired temperature.


Set your thermostat to the temperature you find comfortable and allow the system to operate efficiently. Avoid the temptation to push it to extreme levels. You'll save energy and avoid unnecessary strain on your AC unit.

Myth 2: Closing Vents In Unused Rooms Saves Energy

It seems logical to close the vents in rooms that aren't being used to save energy, right? Well, air conditioning systems are designed to distribute air evenly throughout your home. When you close vents in certain rooms, it disrupts the balance and puts extra pressure on the system.


Closing vents can also cause the cooled air to be redirected into areas with open vents, leading to uneven cooling. Instead, consider using zoning systems if you want to customise the cooling in specific areas. Alternatively, use fans strategically to circulate the cool air and improve comfort without obstructing the airflow.

Myth 3: Bigger AC Units Provide Better Cooling

Many people believe that a larger AC unit will cool their home faster and more efficiently. However, an oversized unit can lead to inefficiency and higher energy bills.


AC units need to be properly sized according to the square footage of the space they need to cool. An oversized unit will cool the room too quickly, resulting in frequent on-off cycles, known as short cycling. This not only wastes energy but also fails to adequately dehumidify the air, leaving you with a damp and uncomfortable environment.


To ensure you have the right size AC unit for your home, consult a professional HVAC technician. They will assess your cooling needs and recommend the appropriate unit that balances efficiency and comfort.

Myth 4: Maintenance Is Unnecessary Until The AC Breaks Down

Regular air conditioning maintenance is often overlooked, with many homeowners only addressing issues when their AC breaks down. However, this neglect can cost you more in the long run. Routine maintenance helps keep your AC running efficiently, extending its lifespan.


Simple tasks like cleaning or replacing filters regularly can improve your AC's efficiency. Additionally, checking refrigerant levels, inspecting the system for any issues and lubricating moving parts when needed can help avoid costly repairs.


By investing in preventive maintenance and scheduling regular tune-ups with a professional HVAC technician, you'll keep your AC in good condition and save money in the long run.
