In New England, late summer blends into crisp mornings and cool nights. One day you’re running the AC, and the next you’re thinking about flipping on the heat. But when exactly should you make the switch?
There’s No One-Size-Fits-All Answer
The right time depends on your home, your comfort level, and the weather in your area. For many New Englanders, the shift happens between mid-September and early October. The main signal is when indoor temperatures dip below what feels comfortable — especially in the mornings and evenings.
Try Using Your Thermostat’s Auto Setting
If your thermostat has an “auto changeover” option, it can handle the transition for you. Set a temperature range (for example, 68 to 75), and the system will cool or heat as needed. This is ideal during weeks when the weather shifts dramatically from day to night.
Humidity Still Matters in Early Fall
When you switch from AC to heat too early, you might end up with a warm but humid home. That can feel uncomfortable. Make sure your system is still managing humidity well, or consider using a dehumidifier for a few more weeks.
Give Your Heating System a Test Run
Before the first cold night arrives, it’s smart to test your heating system. Run it for 10–15 minutes, listen for strange sounds, and pay attention to smells. That brief test could uncover a problem early, while it’s still easy to fix.
Understand Your System
If you have a heat pump, it may automatically shift from cooling to heating when needed. If you use a furnace, you’ll want to make sure it’s clean, tuned up, and ready to go — especially if it hasn’t been used in several months.
Stay Comfortable Without Rushing the Switch
Using layered clothing, opening blinds to let in sunlight, and reversing your ceiling fan (to push warm air down) can help you delay turning on the heat without feeling uncomfortable.
