What to Do If Your Heat Stops Working During a Cold Snap

Winter in our area can be unpredictable, and a sudden cold snap can turn your cozy home into an uncomfortable one very quickly. If your heating system stops working, it can be stressful—but don’t panic. As a family-owned HVAC company, we’ve helped many homeowners through this exact situation. Here’s what you can do while you wait for professional help.

1. Check Your Thermostat First

Sometimes the simplest solutions are the easiest to overlook. Make sure your thermostat is set correctly:

• Check that it’s in “heat” mode

• Make sure the temperature is set higher than the current room temp

• If it’s battery-powered, replace the batteries

If your thermostat is programmable, double-check the schedule hasn’t accidentally been changed.

2. Inspect Your Furnace or Heating Unit

Next, take a look at the system itself:

• Ensure the power switch is on

• Check the circuit breaker for any tripped switches

• Look for a pilot light (if you have a gas furnace) and relight if it went out

Tip: Don’t attempt complicated repairs—safety first. If you’re unsure, call a professional.

3. Check Air Filters and Vents

A clogged filter or blocked vent can prevent warm air from circulating. During cold snaps, airflow is critical:

• Replace dirty filters immediately

• Make sure vents are open and unobstructed

Clean air filters not only help your heating system work efficiently but also prevent unnecessary wear and tear.

4. Keep Your Home Safe and Comfortable

While waiting for service:

• Dress in layers and use blankets

• Close doors to unused rooms

• Keep safety in mind—avoid space heaters if possible, or use them cautiously

Remember, staying warm is important, but safety comes first.
