Have you ever looked at the thermostat in your home and thought about how cold you might be able to make the rooms if it could be set lower than the 60–63°F? That’s the usual limit on thermostats, and people rarely want the house any colder than that. They rarely want it colder than 68°F! But could the air conditioning system conceivably cool the house even lower? Or, to put it another way, just what is the cooling limit for your AC?
Answering these questions isn’t only an exercise in hypotheticals. You can learn important facts about how your AC runs and how best to manage thermostat settings when you know an air conditioner’s limits.
