6 Common Myths About Air Conditioning Debunked

When it comes to air conditioning, misinformation spreads faster than a summer heatwave. From thermostat settings to maintenance routines, myths can lead to unnecessary expenses and inefficient systems.

Today, we’re debunking the most common air con myths to help you save money, improve efficiency, and keep your space comfortably cool.

‍

^{Myth 1:}
Setting the temperature to 16°C cools the room faster

It’s tempting to turn the temperature all the way down when the room feels like a sauna. But here’s the truth: air conditioners cool at a constant rate, regardless of the temperature setting. Setting it to 16°C won’t make the system work faster; it’ll just run longer, wasting energy and potentially freezing the unit.

The fix:

• Set your thermostat to a comfortable temperature, typically around 20°C-22°C.
• Use fans to help circulate the cool air for faster results.

^{Myth 2:}
You don’t need maintenance unless something breaks

‍Many people believe that air conditioning systems are “set it and forget it” appliances. But neglecting regular maintenance can lead to reduced efficiency, higher energy bills, and costly repairs down the line.

The reality:

• Dust and debris accumulate in filters and coils, forcing your system to work harder.
• Small issues like refrigerant leaks or worn-out components can snowball into major problems.

The fix:

• Schedule professional maintenance at least once a year.
• Regularly clean or replace air filters to keep the system running smoothly.

^{Myth 3:}
You should turn the air con off when you leave to save money

‍Turning your air conditioner off completely when you leave the house might seem like a money-saving strategy, but it often backfires. According to a study referenced by PBS, turning off your air conditioner can lead to higher energy usage when you turn it back on because the system has to work overtime to cool a significantly warmer space.

This spike in energy use can negate any savings from shutting it off.The science behind this involves the thermal inertia of buildings: walls, floors, and furniture all absorb and retain heat. When the air con is off, these surfaces warm up and radiate heat back into the air, making the system’s job even harder when you return. 

The reality:

• Maintaining a consistent temperature is more energy-efficient than cooling from scratch.
• Modern systems with programmable thermostats can optimise cooling schedules.

The fix:

• Use a programmable or smart thermostat to adjust the temperature while you’re away.
• Set it a few degrees higher rather than turning it off entirely.

^{Myth 4:}
Closing vents in unused rooms saves energy

‍Closing vents in unused rooms seems logical, but it disrupts the airflow balance in your HVAC system. This can increase pressure, strain the system, and lead to uneven cooling.

The reality:

• Air conditioning systems are designed to cool a specific amount of space.
• Blocking vents can cause air leaks and reduce efficiency.

The fix:

• Keep vents open and ensure proper airflow throughout your space.
• If certain areas are too warm, consider zoning systems or additional fans.

^{Myth 5:}
Maintenance is too expensive to be worth it

‍Skipping maintenance might save a few bucks in the short term, but it can lead to hefty repair bills or even premature system replacement later down the line. Regular upkeep keeps your system running efficiently and extends its lifespan.

The reality:

• Well-maintained systems use less energy and are less prone to breakdowns.
• Many providers offer affordable maintenance plans to spread out costs.

The fix:

• Budget for annual maintenance and think of it as an investment in long-term savings.

^{Myth 6:} 
Installing air con is too expensive

‍One of the biggest misconceptions about air conditioning is that it’s prohibitively expensive. While there are upfront costs, modern systems are more affordable than ever and can even save you money in the long run. For example, we offer a supply and installation package starting at just $1,600. Compare that to some portable units priced at $500, which often lack the power and efficiency of a fully installed system.

The reality:

• Portable units may seem cheaper but often consume more energy and provide uneven cooling - plus you may end up upgrading sooner than you think, so this “cheap” expense now adds to your total air con costs.
• A professionally installed system is an investment in comfort, efficiency, and long-term savings.

The fix:

• Explore cost-effective options like our $1,600 supply and install package. Just ask us!
• Consider the benefits of a professionally installed system, including better energy efficiency and cooling performance.
