HVAC experts cited in recent home advice recommend setting a thermostat near 68°F when heating is needed in fall, while adjusting modestly for sleep or time away. The guidance is not universal: comfort, humidity, local weather and whether a home needs heating or cooling all affect the right setting.
A fall home-comfort report from Hunker cites HVAC experts who recommend setting a thermostat near 68°F when heating is needed, rather than making repeated, large adjustments as outdoor temperatures change. The guidance is a starting point, not a universal prescription: experts say household comfort, humidity, local weather and whether heating is needed all affect the appropriate setting.
Kim Lincoln, an HVAC expert quoted by Real Simple, described fall as a season when temperatures can vary between chilly mornings and warmer afternoons. Lincoln recommended a setting near 68°F for heating, with modest changes for sleep or time away. The advice is intended to avoid constant dramatic thermostat changes while keeping indoor conditions comfortable.
The report also cites a general suggested range of 64°F to 70°F, while stressing that personal preferences and regional weather can shift the comfortable setting. Mike Naughton, founder and CEO of Integrity Energy, told Martha Stewart that lowering the temperature a few degrees at night or during an extended absence can save energy while maintaining comfort.
Other advice in the report is to use a schedule instead of repeatedly adjusting the thermostat by hand. Phil Oliver, co-owner of Air Treatment Heating and Cooling, told Martha Stewart that a programmable or smart thermostat can reduce heating while residents are asleep or away, then restore a comfortable setting when they return. The report says some general guidance recommends a 7-to-10-degree setback when a home is empty or overnight; that figure is not presented as a rule for every household or every heating system.
A Setting That Balances Comfort and Use
Thermostat choices affect both indoor comfort and how much a household uses its heating system. A consistent schedule can reduce the need for repeated manual changes during fall’s shifting weather, while a lower setting during sleep or an extended absence may reduce heating demand. The report frames 68°F as a practical starting point, not a guaranteed way to lower every bill or suit every home.
Local conditions matter. A home in a warm region may still need cooling in early autumn, while a colder area may need heat overnight. People also differ in what feels comfortable, and indoor humidity is another factor Lincoln says should inform adjustments. The advice is most useful as a flexible guide: residents should respond to actual indoor conditions rather than treat one number as right for everyone.

Fall Weather Changes the Thermostat Equation
Autumn often brings large temperature swings within a single day. The source report says that can make it tempting to keep changing the thermostat, but Lincoln advises against dramatic adjustments. Instead, the cited experts recommend a moderate heating setting when heat is needed and a routine that accounts for when people are home, asleep or away.
The report also makes clear that a heating recommendation does not apply when outdoor conditions make cooling necessary. Joe Haycock, president of Fresh Air Concepts, LLC, told Martha Stewart that in places including Texas, Florida, Arizona and Georgia, fall temperatures may stay high and vary through the day. He suggested a broader 70°F to 78°F range in those conditions, with flexibility to avoid unnecessary equipment use. When outdoor air is comfortable, Lincoln said homeowners may temporarily turn the system off and ventilate naturally, provided indoor temperature and humidity remain comfortable.
“Fall is a transition season, so the goal is to find a comfortable setting without constantly making dramatic changes to the thermostat.”

No Single Setting Fits Every Home
The source report does not provide controlled test results comparing energy bills at different thermostat settings, nor does it quantify savings from a particular setback. Its recommendations are expert guidance reported by Hunker, Real Simple and Martha Stewart, not a guarantee of comfort or lower costs for every household.
It is also not clear from the report how the suggested setbacks apply to every type of heating system, building or household. The advice may need to be adapted to local weather, indoor humidity and residents’ needs. The source specifically warns that if temperatures are expected to fall to freezing, homeowners should take precautions against frozen pipes; it does not give a single safe minimum setting for all homes.
Adjust Settings to Local Conditions
For households preparing for fall, the cited guidance is to begin near 68°F when heating is required, then make modest adjustments based on comfort and indoor humidity. A programmable thermostat can follow a regular schedule, lowering the setting during sleep or an extended absence and raising it when the household is home.
Residents should also check the forecast and their indoor conditions before turning heating or cooling off. In mild weather, natural ventilation may be suitable if indoor temperature and humidity stay comfortable. When freezing weather is expected, homeowners should plan for pipe protection rather than relying on a low thermostat setting alone. The right setting remains a household decision shaped by weather, equipment and comfort.
Key Questions
What temperature do experts recommend for heating in fall?
The report cites a recommendation to set the thermostat near 68°F when heating is needed. It describes that number as a starting point, not a setting that suits every home.
Should I lower the thermostat at night or when I leave?
The experts quoted in the report support lowering the setting modestly during sleep or an extended absence. The report also mentions general guidance of a 7-to-10-degree setback, but households should adapt that advice to comfort, local conditions and their equipment.
Is 68°F right for every region?
No. The report says local weather can change what is comfortable or necessary. It cites warmer-region guidance of 70°F to 78°F in some conditions, and notes that early fall may still call for cooling in hot areas.
Can I turn my HVAC system off when the weather is mild?
Kim Lincoln told Real Simple that homeowners can temporarily switch the system off and use natural ventilation when outdoor conditions are comfortable and indoor temperature and humidity remain in a safe, comfortable range.
What should I do if freezing weather is forecast?
The source advises taking precautions to prevent frozen pipes when temperatures may drop to freezing. It does not specify a universal minimum thermostat setting, so homeowners should account for their home and local conditions.
