As summer finally begins to fade into fall, many Savannah area residents start looking forward to cooler evenings and mornings and turning on their furnace systems for indoor comfort. At Galbreath Heating & Air, we often hear questions from homeowners about when to switch from AC to heating in Georgia and South Carolina. While there isn’t one specific date that works for every home, understanding the seasonal transition and paying attention to changing temperatures can help you make the switch at the right time.
Understanding the Seasonal Transition
In our region of Georgia and South Carolina, temperatures typically begin to drop in the fall, signaling the time to consider switching your system from AC to heating. During the shortening daylight hours, mornings and evenings tend to cool down, while afternoons might remain warm. Homeowners should closely monitor weather patterns and consider switching when overnight temperatures regularly dip into the 50s or lower. These patterns can vary from year to year, so paying attention to daily temperature fluctuations can help you choose the right time to switch and maintain comfortable, energy-efficient indoor temperatures.
When Should You Turn Your Heat On?
There isn’t a specific date when every homeowner in Georgia or South Carolina should switch from AC to heating. Instead, pay attention to both outdoor temperatures and how comfortable your home feels. When overnight temperatures consistently fall into the 50s or lower and your home begins to feel chilly in the mornings, it may be time to turn on the heat.
It’s also a good idea to test your heating system before you actually need it. Turning the system on during a mild fall day gives you an opportunity to make sure warm air is coming from the vents and identify potential problems before colder weather arrives.
How To Safely Switch from AC to Heating
To ensure a smooth transition and reduce stress on your HVAC, follow these steps when switching between AC and heating. Taking a few minutes to prepare your system before the first cold day can help you catch potential issues early. It can also help ensure your heating system is ready to provide reliable comfort when you need it.
Thermostat Adjustment
Switch your thermostat from “cool” to “heat” mode. Perform a quick test by setting the temperature a few degrees higher than the current room temperature to make sure the heating system activates as expected and circulates warm air.
During the early weeks of the heating season, consider keeping your thermostat around 68°F during the day and lowering it when you’re sleeping or away from home. Adjusting the temperature based on your schedule can help maintain comfort without unnecessary heating.
Air Filter Inspection
It’s always important to inspect and replace air filters throughout the year. Before switching to heating, check your filter and replace it if it is dirty or clogged. A clean filter supports proper airflow, system efficiency, and cleaner indoor air.
Clear Vents
Run a visual inspection of all air vents and registers serving your indoor spaces. Be sure they are clean and clear of obstructions such as carpets, furniture, or curtains so heated air can circulate properly throughout your home.
Test the Heating System
Before colder weather arrives, turn your thermostat to heat and raise the temperature a few degrees above the current indoor temperature. Make sure warm air is coming from the vents and watch for unusual noises, odors, or other problems.
Why Fall HVAC Maintenance Matters
Before cooler weather settles in, professional HVAC maintenance can help make sure your heating system is ready for the season ahead. A maintenance visit gives a technician an opportunity to inspect important components, check system performance, and identify potential problems before they lead to an unexpected breakdown.
Fall maintenance can also help your system operate efficiently throughout the heating season. Cleaning and inspecting the equipment, checking airflow, and addressing minor issues can reduce unnecessary strain and help maintain consistent indoor comfort.
If your system has not been serviced recently, fall is a good time to have it checked before colder temperatures arrive. Regular maintenance can help you stay ahead of repairs and ensure your HVAC system is prepared for the seasonal change.
