AC Settings for Efficiency and Coolness: Insights from an Air Conditioning Company in Lisle, Illinois

It happens every year — as the outdoor temperatures start rising, we start turning on our air conditioning systems to keep our homes cool. However, this is also the time to pause and consider a suitable temperature that allows you to maintain a comfortable environment without overloading the air conditioner.

Below, this air conditioning company in Lisle, Illinois is going to explain some things you can do to keep your AC system running efficiently this summer.

Thermostat Temperature

Efficient air conditioning thermostat in Lisle, IllinoisWhen returning home on a hot summer day, it can be tempting to crank up the AC system as soon as you walk in the door. However, this immediate need for comfort can cause your energy bills to spike. Instead, you should set your AC somewhere around 78oF. This is the recommended temperature for cooling your home while being as energy efficient as possible. However, there is no “one size fits all” rule, so you can always experiment with a slightly cooler temperature cooler until everybody in the house feels comfortable.

Another great way to save energy is by installing a programmable thermostat. It allows you to switch off the AC when there is no one at home, and then begin lowering the temperature just in time so that you return to a cool, comfortable house.

Avoid Overheating

Several household appliances — such as dryers, dishwashers, stoves, and more — emit a lot of heat when they’re working. Of course, it’s not possible to completely stop using these necessary appliances, but it’s best to limit their usage whenever possible to help prevent your home from overheating. After all, the more heat that’s generated in your home, the harder your air conditioner will have to work.

You may want to consider alternative methods to conserve energy, like drying clothes out in the sun, running the dishwasher only when it’s full, and running the washing machine after the sun goes down.


An overly humid home is an uncomfortable home. Some ways to reduce humidity levels are by taking shorter showers and turning on the exhaust fans in the bathrooms. Alternatively, you may want to consider installing a dehumidifier and running it during the humid months. As always, your local Lisle air conditioning company will be happy to review your options.

Turn On the Fan

A ceiling fan or a box fan consumes a lot less energy than your air conditioning system. When these fans are on, you can set your air conditioning temperature a few degrees higher than you normally would. This will make you rooms feel cooler, while also saving energy.

Familiarize Yourself with the AC Settings

To find the right balance between AC efficiency and indoor comfort levels, you should be aware of these basic AC settings:

  • AC Fan Speed: The AC fan is the component that is responsible for increasing the amount of hot or cool air in the home. The fan speed can be set at low, medium, high, and auto. Unless you need fast cooling, it is best to use the auto setting, which helps maintain the desired temperature in the most energy efficient way
  • AC Timer Setting: Most modern ACs allow you to set the run time, and automatically shut off when you are out of the house, thereby saving you energy
