Energy Efficiency: Should I Leave the Air Conditioning on all Day?

Many establishments including care homes, schools, doctors surgeries and workplaces require the use of air conditioning to ensure a comfortable environment for their visitors and patients all year round. However, the use of air conditioning systems can drive your energy bills up if they aren’t used efficiently. There are many steps you can take to ensure that you are using your AC system effectively, in order to feel the benefits from your investment and keep your energy bills down. The age-old question of whether it is more efficient to leave the air conditioning on at a low rate all day or leave off and turn on again when you the temperature of your environment has shot up still causes a lot of confusion, however, there is a simple answer.

It is more energy efficient to turn your air conditioning off when your premises will be empty for long periods of time i.e. overnight, than to leave it at a steady temperature all the time. This technique has been proven many times to be the most efficient and is called thermostat setback.

Whilst you may have heard people say that your air conditioning system will have to work harder in order to cool down a warm room if it has been left off, the truth is that an air conditioning unit will work at the same consistent rate, in-line with the setting you put it on. It will not work harder than the setting it is put at just because the temperature of your room is higher.

It actually takes quite a lot of energy to maintain a consistent temperature all day and air conditioners will work most efficiently when at full speed. The greater the difference between your properties current temperature and the temperature you would like it to be, the more quickly it will cool down with an air conditioner.
