No matter what temperature you set your home to, a traditional air conditioner has only two settings: on, and off. A wide range of cooling temperatures is achieved by the thermostat simply turning the A/C off once the temperature is reached, and turning it back on when the house warms up a little. While this works, it can produce intermittent noise and some temperature swings, and it’s not the most efficient way to handle matters. Two-stage cooling is an improvement.
With two-stage cooling, the air conditioner’s compressor has two speeds: high and low. During cooler days, the compressor can run at a lower speed, expending less energy to run while also running more consistently. Less on-and-off noise makes it through your vents, and the temperature remains more stable.
On those scorching Peachtree City days, though, the A/C can switch into high gear to meet the increased cooling load. That way, your air conditioner can always be ready to deliver the amount of cooling you need.
A two-stage cooling system also pairs well with a variable-speed fan, and many are sold combined. Like your compressor, a traditional central A/C fan can only be on or off, cycling air through your ductwork or not. A variable-speed fan, however, can dynamically adjust just how much air is being circulated, further smoothing out the temperature curve in your home.
Yet another benefit of this more-constant air circulation is the fact that most air cleaners require air to be circulating to be cleaned. Your HVAC air filter, as well as UV lights, electrostatic air cleaners, or HEPA filtration devices can only work when air is passing through. That means that two-stage air conditioners and variable-speed fans won’t just keep you more comfortable, they can actually keep you healthy, as well.
