As we transition from summer to fall, the air turns crisper, and the nights grow colder, you may find yourself wondering: When should I turn on the heater?

While fall in the Hickory and Denver area is filled with seasonal activities, like a day at the Taylorsville Apple Festival or visiting one of the many local pumpkin farms, there's nothing better than coming back to a warm and cozy home.

When’s the Best Time to Turn on the Heat in Hickory & Denver?

In the Conover region, nighttime temperatures usually start dipping into the low 40s by late October to early November, which is when most homeowners begin turning on their heat. That said, weather in the foothills can be unpredictable.

• If we get an early cold snap, you might need to fire up the heater as early as mid-October.
• On the other hand, if the weather stays mild, you can likely hold off until early November, which can help save on energy costs.

A good rule of thumb: When your indoor temps consistently fall below 68°F and it feels chilly at night, it’s time to warm things up.

What Should I Check Before I Turn the Heat On?

Before you crank up the heat this fall in your North Carolina home, it's a good idea to run through a few quick safety and maintenance checks. These simple steps can help ensure your system runs efficiently, and safely, as the temperatures drop.

  1. Check Your Furnace Filter: Replace or clean the filter if it's dirty. A clean filter improves airflow, keeps your air cleaner, and helps prevent your furnace from overworking or malfunctioning.
  2. Clear the Area Around the Furnace: Make sure there's no clutter, storage boxes, or flammable materials near your furnace. Keeping the area clear helps reduce fire risk and improves air circulation.
  3. Test Smoke and Carbon Monoxide Detectors: Follow the manufacturer’s instructions to test your detectors and replace the batteries if needed. This is especially important before winter when your furnace runs frequently.
  4. Inspect Outdoor Vents: Check that your exterior furnace or HVAC vents are free of leaves, dirt, and other debris especially after a windy fall day in the foothills.

How Do I Turn My Heater On?

Now that you know when to turn on the heat in the Hickory area, here’s how to make sure everything is ready to go when those chilly nights settle in:

  1. Set Your Thermostat to “Heat” Mode: Double-check that your thermostat is switched from "cool" or "off" to "heat," then raise the temperature to kickstart the system.
  2. Turn On the Furnace Power Switch: Locate the main power switch (often a red switch near the unit) and ensure it's set to “on.”
  3. Listen for the Heating Cycle: Once everything is on, you should hear the system begin to run. If you notice any unusual sounds, smells, or if your home isn't warming up, it's best to call a local HVAC professional for service.
