October in South Carolina can have your HVAC system wondering what season it is.
One afternoon you're running the air conditioner—and the next morning you're thinking about turning on the heat.
This is actually a great time to pay attention to how your HVAC system transitions between heating and cooling.
If you have a heat pump, your outdoor unit doesn't take the winter off. It reverses operation and becomes part of your heating system.
If you have a dual-fuel system, your heat pump and gas furnace work together, switching between two different heat sources depending on conditions and how the system is configured.
Watch for:
- Heat that doesn't seem warm enough
- Auxiliary heat running excessively
- A heat pump that won't change properly between heating and cooling
- Large temperature swings inside the home
- New noises when switching modes
- An unexpected increase in your electric bill
- A gas furnace that doesn't ignite properly
And here's an important point: don't wait for a 25° morning to find out your heating system has a problem.
Turn the heat on now. Let it run. Make sure everything operates normally while the weather is still mild.
