Have you ever looked at your thermostat and wondered just what all those fan modes on the selector switch really mean? Is high better than low? What does “smart fan” mean? Can you use your Atlanta AC system as just a fan?
Yes, AC systems and thermostats these days have several fan modes, some of which are straightforward, and some of which are confusing. To see what each of these settings means and figure out which one you should be using, read this brief guide.
These are the standard settings for air conditioner fan speed, and they pretty much speak for themselves. The “low” setting represents the slowest fan speed, which also uses less energy than the faster speeds. The “high” setting is obviously the fastest. Some models may not have the “medium” setting, but should still have the other two. Keep this at the lowest comfortable setting to save energy.
Sometimes labeled “Energy Saver” or “Smart Fan,” this mode is designed to automate your home’s cooling. An automatic mode does pretty much exactly what the name implies – it automatically turns the fan on and off depending on the temperature of the house. Some newer, “smarter” systems can also adjust the fan speed automatically in order to cool the house quicker. Automatic fan modes are the most energy efficient and represent the least hassle for the user, especially in combination with a programmable thermostat.
- Fan Only
Some air conditioner models also have a mode that operates only the fan. With this setting activated, the AC will do no actual cooling and the compressor/condenser unit will not run. Instead, the air handler will just circulate air, which helps the home feel cooler. This setting can save energy during those times when it is not necessary to run the whole AC to keep the house comfortable. However, a fan by itself does nothing for actual cooling, so leaving your AC in fan only mode while the house is empty will actually waste energy.
While having so many modes can get confusing, they are designed to give you maximum control over how your home is cooled, as well as how much energy your AC system consumes. With that in mind, you can choose the right configuration of settings that works for you. For more information about your Atlanta air conditioning system, give Cool Air Mechanical a call!
