Unpredictable temperatures during the fall can cause your energy bills to skyrocket if your HVAC system is still running on summer settings. As the days get shorter, finding the sweet spot between chilly mornings and mild afternoons doesn’t require constant manual tweaking. All it takes are a few strategic thermostat adjustments to maintain optimal comfort without incurring significant heating costs. 

Inspect and Clean Before Switching Modes

Before making any changes to your settings, make sure to inspect your thermostat first. Dust and insufficient battery levels can cause the sensor to misread temperatures, causing your furnace to cycle on and off more than it should.

That’s why it’s important to:

• Install fresh AA or AAA batteries, depending on your unit, to avoid erratic system behavior.

• Clear out dust using a soft brush or a can of compressed air to remove any buildup that blocks or insulates the internal sensors.

• Remove appliances that give off heat near the sensors. Heat from lamps, TV sets, or space heaters can skew the sensor’s readings into thinking it’s hotter than it is. 

Find Your Seasonal Sweet Spot

With your unit clean and ready, you can start tweaking its fall setting to suit your needs. But the right setting means balancing comfort levels with energy use. 

The Department of Energy recommends keeping your thermostat at 68°F when you’re awake and at home. However, if that temperature feels a bit chilly, you can gradually dial down your setting over a week to give your body some time to adapt. Remember, every degree you lower your heat saves about 3% on your energy bill. 

Meanwhile, you lower the setpoint by 7°F to 10°F during the hours when everyone is at work, school, or fast asleep. There is no need to heat the house to full comfort levels during these times, and your system can easily bring the space back up to the right temperature when you return.

Setting your thermostat to a lower temperature for 8 hours a day can cut your overall heating costs by up to 10% a year. 

Set an Automated Schedule That Works

Having a manual unit paired with your HVAC means you have to constantly remember your preferred thermostat fall setting. Upgrading to a programmable or smart model takes that daily friction off your plate, allowing you to automate energy-saving routines.

Set these baseline schedules to maximize comfort and cut costs:

• Daytime Setbacks: Program the system to lower the temperature 30 minutes before the last person leaves in the morning, and raise it back to 68°F shortly before you return.

• Lower Overnight Temperatures: Most people sleep better in a cooler room. You can drop the target setpoint to around 62°F to 65°F overnight, depending on how cool you want your room to be.

• Avoid Constant Manual Changes: Setting the thermostat to 75°F will not warm the house up any faster than setting it straight to 68°F. HVAC systems run at a fixed speed, so over-adjusting will only force the unit to run longer and waste energy.

If you already use a smart thermostat, check your app to verify that these seasonal automation routines align with your actual fall schedule.

When Maintenance Isn't Enough

Sometimes, a seasonal check can reveal deeper control problems. If your system short-cycles constantly, ignores schedule changes, or displays temperatures that clearly do not match the room's actual air temperature, the thermostat itself may be failing. Wiring corrosion, worn circuitry, or aged internal relays eventually necessitate replacement.

Fortunately, a dead thermostat doesn't require overhauling your entire HVAC setup. Swapping out the old unit for a compatible new model can restore total system balance without breaking the bank.
