Dueling Central Air Conditioners

Central air conditioners literally draw a ton of electricity. Just turn on your AC and see what happens to your electric meter.

If you cannot live without both central air conditioners during a power outage, simply use our chart below to quickly determine your (a) size and (b) switch.

For example, you want to power two 4-ton central air conditioners.

Since an essential circuit standby generator system lacks the intelligence to alternate two central air conditioners, you’ll need a 12-kilowatt standby generator with a smart circuit automatic transfer switch instead.

As a general rule, if one of your two central air conditioners is a 5-ton model, always go with a 20 kilowatt standby generator with a smart circuit transfer switch.
