The simple answer to this question: No, turning the thermostat as low as possible won’t speed up cooling your home.
This is a common misunderstanding people have about both thermostats and air conditioning systems, and it results in an unfortunate waste of energy and additional strain on ACs that can shorten their lifespan and make repair needs more frequent. We could just tell you to maintain a higher thermostat setting in the 70s (78°F is recommended for general comfort) and leave it at that, but we believe that informing our customers helps both them and us. So below we’ll explain in greater depth why setting the thermostat too low is unhelpful and can backfire on you.
