One of the most common heating and cooling questions homeowners ask is:
What temperature should I set my thermostat?
For homeowners in Oshkosh, Fond du Lac, Appleton, and the surrounding Wisconsin area, the best thermostat setting depends on comfort, energy efficiency, home size, insulation, and the time of year.
As a general rule:
- Summer thermostat setting: usually around 72–78°F
- Winter thermostat setting: usually around 68–72°F
Some homeowners prefer the house cooler. Others want to save more on energy bills. There is no perfect number for every home, but finding the right balance can help keep your home comfortable without making your furnace or air conditioner work harder than needed.
At Wehle Good Heating and Cooling, we help homeowners in Oshkosh, Fond du Lac, Appleton, and nearby Wisconsin communities keep their heating and cooling systems running efficiently through every season.
Best Thermostat Setting for Summer
During the summer, many homeowners set their thermostat somewhere between 72°F and 78°F.
If comfort is your top priority, you may prefer the lower end of that range. If energy savings are more important, setting the thermostat closer to 76–78°F may help reduce how often your AC runs.
In Wisconsin, summer weather can be hot and humid. Even though our summers are not as long as other parts of the country, AC systems in Oshkosh, Fond du Lac, and Appleton still work hard during warm stretches.
A good summer thermostat range is:
- 72–74°F: cooler and more comfortable, but may use more energy
- 75–76°F: balanced comfort and efficiency for many homes
- 77–78°F: better for energy savings if your household is comfortable with it
If your AC has to run constantly to maintain the temperature, there may be another issue. Dirty filters, low refrigerant, dirty condenser coils, poor insulation, or an aging AC unit can all make cooling more difficult.
Best Thermostat Setting for Winter
During the winter, many homeowners set their thermostat around 68°F to 72°F.
Wisconsin winters can be tough, and homeowners in Oshkosh, Fond du Lac, Appleton, and nearby areas rely heavily on their furnaces. Setting the thermostat too high can make your furnace run longer, which can increase energy bills and put more strain on the system.
A good winter thermostat range is:
- 68°F: commonly used for energy savings
- 69–70°F: comfortable for many households
- 71–72°F: warmer, but may increase heating costs
If your home still feels cold even when the thermostat is set higher, the issue may not be the thermostat setting. Your home may have air leaks, poor insulation, dirty filters, ductwork problems, or a furnace that needs service.
Comfort vs. Energy Savings
The right thermostat setting depends on your goals.
If your main goal is comfort, you may want your home cooler in the summer and warmer in the winter. If your main goal is lowering utility bills, you may want to adjust your thermostat a few degrees closer to the outdoor temperature.
Small thermostat changes can make a difference. Even changing the temperature by a couple degrees can reduce how often your furnace or AC runs.
For example:
- In summer, setting the thermostat from 72°F to 76°F may reduce AC run time.
- In winter, setting the thermostat from 72°F to 68°F may reduce furnace run time.
The best setting is one your household can live with while still keeping energy use reasonable.
Should I Change the Thermostat When I Leave the House?
In many cases, yes. Adjusting the thermostat when you are gone can help save energy.
During summer, you may be able to raise the temperature a few degrees when nobody is home. During winter, you may be able to lower the temperature a few degrees while you are away.
However, you do not want to make extreme changes. If you set the temperature too far away from your normal comfort level, the system may have to work hard to catch back up when you return.
A smart or programmable thermostat can help by automatically adjusting the temperature based on your schedule.
Should I Lower the Thermostat at Night?
Many homeowners lower the thermostat slightly at night during winter and raise it slightly at night during summer.
This can help reduce energy use while still keeping the home comfortable for sleeping.
In winter, some homeowners sleep comfortably with the thermostat around 65–68°F. In summer, some homeowners sleep best around 70–74°F, depending on humidity, bedding, and personal comfort.
Again, it depends on the home and the people living in it.
Why Your Home May Not Feel Comfortable at the Right Temperature
Sometimes the thermostat says one thing, but the house feels different.
For example, your thermostat may say 72°F, but certain rooms still feel too hot or too cold. This usually means there is another issue affecting comfort.
Common causes include:
- Dirty air filter
- Poor airflow
- Leaky ductwork
- Poor insulation
- Drafty windows or doors
- Thermostat location
- Aging furnace or AC unit
- High indoor humidity
- Uneven sun exposure
If your thermostat is set correctly but your home still does not feel comfortable, it may be time to have your HVAC system inspected.
Thermostat Location Matters
Where your thermostat is located can affect how your heating and cooling system runs.
A thermostat should be placed where it can read the home’s temperature accurately. If it is too close to sunlight, drafts, vents, appliances, or exterior doors, it may give inaccurate readings.
Poor thermostat placement can cause:
- Furnace or AC running too often
- System not running enough
- Uneven temperatures
- Higher energy bills
- Rooms that never feel comfortable
If your thermostat seems inaccurate, an HVAC professional can help determine whether placement, wiring, calibration, or replacement may be needed.
Should I Use “Auto” or “On” for the Fan?
Most homeowners should keep the fan setting on auto.
When the fan is set to auto, it only runs when the furnace or AC is actively heating or cooling. This usually saves more energy.
When the fan is set to on, the blower runs continuously, even when the system is not heating or cooling. This can help circulate air, but it may also use more energy and can sometimes make the home feel less comfortable, especially in humid weather.
If your energy bill is high, checking whether the fan is set to “on” instead of “auto” is a good first step.

When to Call an HVAC Professional
You may want to call an HVAC professional if:

- Your furnace or AC runs constantly
- Your energy bills are higher than normal
- The thermostat reading seems wrong
- Your system turns on and off too often
- Your AC cannot control humidity
- Your furnace struggles during cold weather
A thermostat setting can only do so much. If the system is not working properly, changing the temperature may not solve the real problem.
FAQ: Thermostat Settings
What temperature should I set my thermostat in summer?
Most homeowners set their thermostat between 72°F and 78°F in the summer. A higher setting may help save energy, while a lower setting may feel more comfortable.
What temperature should I set my thermostat in winter?
Most homeowners set their thermostat between 68°F and 72°F in the winter. Lower settings may help reduce heating costs, while higher settings may feel more comfortable.
Is 78°F too hot for summer?
It depends on your comfort level. Some homeowners are comfortable at 78°F, especially with fans and good airflow. Others prefer 72–75°F.
Is 68°F too cold for winter?
For some people, 68°F feels comfortable. Others may prefer 70–72°F. If your home feels cold at 68°F, insulation, airflow, drafts, or furnace performance may be part of the issue.
