The summer just started and it's already breaking records! Some parts of Canada and the United-States are affected by historical heat waves. If you didn't have an air conditioner you probably purchased one! 

There are common myths around this popular appliance and some of them couldn't be any further from the truth! For example, no the air conditioning will not make you catch a cold!

 Discover 8 air conditioning myths you can stop believing right now.

1. Coils and fins do not need to be cleaned

The evaporator coils and fins of an air conditioning unit allow heat to be transported from the refrigerant into the air, as do the condenser coils absorbing heat from the interior of your house. This important process of moving heat can be hampered by couches of dust and dirt. If you never check the condition of the coils, this protection costs you money and reduces the efficiency of the system.

Clean your unit at the start of the hot season and make sure to do it every now and then - especially after a storm or high winds. 


2. Set the thermostat to a lower temperature to cool faster

People often think that by setting their thermostat to a very low temperature believing that their system would cool the room or house faster. However, this is not the case. The air conditioner works just as hard to lower the temperature by 1 degree as it does for 20 degrees. It is a simple matter of time! 

3. The bigger, the better 

Air conditioning units are designed to cool the required number of square feet. Therefore, if an appliance is intended for a smaller space than yours, it will work too hard to cool the air, wear out faster, and strain to meet demand. If the device is intended for a larger space more than yours, it will turn on and off continuously, wear out and become less reliable over time. So always read about the square footage rather than the size of the appliance! 

4. Keep an air conditioner until it stops working

The initial cost of replacing your air conditioning unit is high, but that doesn't mean you shouldn't buy a new one if you needed it. An old device will perform poorly, cost you money in repairs, and possibly cause more problems than it's worth. If your air conditioner is between 10 and 12 years old or even older, investing in a newer, more efficient model will save you money and prevent premature wear.

5. Close all the vents 

This process usually does not save energy. A residential heating and cooling system is designed so that the air handler (or blower) carries a certain amount of air regardless of what events are open or closed. Closing vents will decrease the total amount of air pushed by the blower and its efficiency.


6. The AC unit does not need preparation before summer

Really ? Make sure your air conditioner is ready to operate before the hot weather arrives! 

7. You can catch a cold with an air conditioner

Colds are caused by viruses, not cold temperatures. This is a common myth! 

8. Programming the thermostat at the same temperature all day is more economical

You can reduce your electric bill by 20% by setting the thermostat on your air conditioning unit 4 to 6 degrees higher when you are at work or on vacation and automatically lowering the temperature to 25.5 ⁰C when you return home.
