Air conditioners have been with us for more than a century, and they first entered homes in the 1920s. During this long period of service keeping us cool, ACs have developed many myths about their operation. Some of these are harmless misunderstandings, while others lead to energy waste and discomfort. In this post we’ll look at three of the more common myths that we encounter regularly in our work.
Our skilled employees at Avis Plumbing, Heating and Air know everything about air conditioning in Riverside, CA to make sure that your AC always runs its best. Call us—any time of the day or night—when you need repairs to restore your cooling.
1. Air conditioners create cool air
This is the most basic misunderstanding that non-specialists have about air conditioning. Since cool air comes from the vents connected to an AC, it stands to reason that the air conditioning is creating the cool air. However, this is not the case: air conditioners are removing heat from the air, which makes the air feel cooler to us. This heat must go somewhere, so the air conditioner moves it to the outside. This is the reason that air conditioners must have indoor and outdoor components: an AC that sits entirely inside a home with no way to ventilate would just put the heat it removed from the air and put it right back in it.
2. Air conditioners contribute to ozone-depletion
This used to be true, unfortunately. For many years, the most common type of refrigerant found inside air conditioners was R-22, a hydrochlorofluorocarbon that contributed to ozone layer loss. However, the U.S. initiated a phase-out program to eliminate R-22 entirely by 2020. At this point, all new air conditioners use a non-ozone-depleting refrigerant, of which the most common is R-410A. (This is likely the refrigerant that is currently circulating through your home’s air conditioner.)
3. Turning an AC’s thermostat to its lowest setting will cool your home faster
Here is a myth that leads to tremendous energy waste. If you crank your thermostat all the way down to the lowest setting, which is often 50°F on many models, you are not going to cool down your home any faster. That’s not how the thermostat or the air conditioner works. What will happen is that the AC will stay on longer until it has cooled the house down to the set temperature. This drains excess energy, puts extra strain on the system, and will end up delivering you an uncomfortably low temperature. It is far more efficient and comfortable to keep the thermostat set at 72°F or thereabouts.
