You could turn off your Long Island air conditioner when you’re away for several hours, but it’s usually more efficient to raise the temperature on the thermostat instead.
In summer, air conditioners use more energy when they’re first turned on. It takes long cooling cycles (or high variable compressor loads) to bring indoor temperatures down to a comfortable range of 70°F to 77°F. If you leave your home and turn your system off, your system will use a massive amount of energy to cool the interior once you get back.
Raising the temperature when you’re not home means your system is still running, but the cooling cycles or compressor loads will use much less energy.
It sounds counterintuitive, but it’s the best way to reduce your total energy consumption.
Adjusting the Thermostat vs. Full Shutdown
Instead of turning off your AC, raising the thermostat by a few degrees will reduce energy usage with a minimal impact on comfort.
Compare what happens with a full air conditioner shutdown vs. raising your thermostat when you aren’t home:
|

Consistent humidity management to protect your home and everything inside it. |
The Alternative: Installing a Smart Thermostat
