HVAC pros say a 7-degree thermostat setback can lower bills without sacrificing comfort

Heating and cooling are often among the largest contributors to a home's energy costs.

When temperatures swing hard in either direction, a modest thermostat change may help stop your utility bill from climbing as quickly.

HVAC experts told Men's Journal that adjusting your thermostat by about 7 degrees Fahrenheit when you head out can cut unnecessary energy use while still keeping the house reasonably comfortable.

What's happening?

Rather than focusing on one exact number, experts have said the bigger issue is how large the difference is between the temperature inside your home and the temperature outdoors. When that gap is smaller, your heating and cooling system does not need to work as hard.

Michael Haines, chief commercial officer of AC Direct, said, "As a general rule, I tell homeowners to keep the thermostat around 76 to 77°F in the summer when they're home and 82 to 85°F when they're away. In winter, 68 to 72°F while you're home and 60 to 65°F when you're away is a good balance between comfort and energy savings."

If your current system is old, exploring an upgrade can make an even bigger difference. Through its heat pump marketplace program, EnergySage can help you find efficient heating and cooling solutions for your home and connect you with vetted installers, helping you understand your options and slash your energy bills with new, efficient HVACs.

Why does it matter?

Because heating and cooling are often among the largest contributors to a home's energy costs, even a moderate thermostat setback can help. If the system runs less often, it may reduce the sharp bill increases many homeowners see during peak seasons.

Men's Journal noted that Tamer Sayed, a licensed HVAC technician and owner-operator of Tamas Mechanical, said completely shutting the system off when you leave can backfire by making it work harder later to restore the previous indoor temperature.

Travis Arnesen, vice president of marketing at Service Experts, also warned that a full shutdown can allow indoor humidity to build up, which can make the home less comfortable and potentially put added strain on furnishings, electronics, and wood materials.
