Some myths are harmless. But some myths can be outright costly.
Take the way our homes operate our heating and cooling systems, for instance. While we depend on our AC on the warmest days of the year, we often don’t think much about the process. Worse, we sometimes believe myths that aren’t true. And that can impact everything from how comfortable you are in your home to how much you spend on utility bills each month.
Do you believe these AC myths?
#1: Air conditioners use refrigerant
You may have read about the different types of refrigerant located in a home air conditioner. That makes many homeowners believe that AC equipment uses refrigerant like a car uses gas. Not true.
A home’s AC does not use refrigerant. Instead, it is contained in a sealed system, meaning refrigerant should never escape the system. If you need more refrigerant, it’s because you have a leak that needs fixing.
#2: Larger air conditioners must be better
If you have warm rooms in your home, installing a larger air conditioner must mean you can get more conditioned air throughout your home, right?
Sizing an AC unit is like sizing a foot for a shoe. You wouldn't purchase a larger shoe to run more miles. If the AC unit is too large, it will cool your home too quickly, causing it to cycle on and off to frequently. This will make you uncomfortable because the AC unit won’t be able to perform its full function. AC units need to run long enough to dehumidify your home. If this doesn’t occur, it won’t properly condition your air, and could reduce the efficiency of your equipment over time.
#3: Turning the thermostat down low makes the AC cool faster
If it’s really hot in your home, simply turn it to your desired temperature and wait. It’ll get there.
The thermostat isn’t an “all or nothing” appliance. You will never have instant cold air. Instead, a thermostat is an on/off switch that talks to your AC unit. It tells it to start delivering cold air, then tells it again when to stop. Setting it for the right temperature ensures it will reach your preferred limit and keep it there once it’s achieved.
