Setting the Optimal A/C Temperature in Your Home

Setting the Optimal A/C Temperature in Your Home

While there are several ideas about how to determine the ideal temperature for your home in the summer, certain rules cannot be denied. For example, the lower you set your thermostat, the more your A/C system will work, and the higher your energy costs will be. Finding the optimal A/C temperature for a home involves shifting your priorities as well as considering factors that make your home hotter. Here are tips on finding the ideal temperature for your Midtown home’s air-conditioner system.

Rules of Heat Transfer

Anyone who has lived through any Atlanta summer knows the heat can be unbearable. However, there are ways you may be making your A/C system work harder in the hot months. As the EPA points out, there is no reason to buy into the myth that warmer homes require more energy to cool. In fact, warmer homes allow less heat to enter because heat gravitates towards cooler spaces.

You are forcing your HVAC system to waste a great deal of energy by keeping it on when there is no one at home. It won’t take more energy to cool off a home from scratch than it would if you had the A/C running throughout the day. Managing a cooling system is best handled with a programmable thermostat. You can use these devices to make sure your system is off when you are at work and to increase the temperature slightly when you are asleep, which is a time when body temperature falls.

The Optimal A/C Temperature for Energy Savings

Using a programmable thermostat allows you keep your home at 78° Fahrenheit in the summer, which is the temperature the EPA recommends for optimal energy consumption. The numbers show just how big a difference a few degrees can make. Turning up a thermostat between 10 and 15 degrees for 8 hours (say, from 68°F to 78°F) could save you 5 to 15 percent on energy bills. It works out to about one percent energy savings for every degree you push in a warmer direction.

The same principles apply to heating in winter months, when experts suggest you set the thermostat to 68°F. Of course, the only way to enjoy these savings is by observing regular maintenance for HVAC equipment, sealing air leaks in windows and maintaining ductwork. When your home’s building envelope is sealed and HVAC equipment is running efficiently, you will see value in every bit of energy you use.

Casteel technicians will tune up your HVAC system and seal ductwork so you don’t waste energy. By setting the optimal A/C temperature and using energy wisely, you’ll get the most for your money on energy bills.
