As an expert in the field of energy efficiency, I have heard many tips and tricks for reducing energy bills. One of the most common pieces of advice is to keep your home at a constant temperature. The theory behind this is that by setting your thermostat to a specific temperature, your air conditioning system will consume less energy. This is because the system won't have to constantly turn on and off, which uses more energy than simply running at a steady temperature. However, the problem with this advice is that it assumes that heat loss in your home remains the same regardless of the temperature.
As we know from the Law of Cooling, this is simply not true. Heat loss does not work in a linear fashion. When you lower the thermostat, your home will lose some heat, but it won't lose all of it immediately. In fact, heat loss slows down over time. Another misconception is that air conditioners have to "work harder" to cool down a house after a hot day.
This is not the case. In reality, it takes less energy to cool something from 62°F to 72°F than it does to cool something from 32°F to 72°F. Air conditioners actually operate more efficiently at full power and can run steadily all day long.
