Frequently Asked Questions

If your home heater is not working, do a few safe checks, then schedule service if it still won’t run. The most common cause is a thermostat or power setting, with airflow problems next that make safety switches stop heat. A clogged filter can trip a furnace limit or freeze a heat pump, so heat can fail without a big warning. Our technicians handle no‑heat calls throughout the Nampa area every day. We also offer 24/7 on‑call help.

Before you call, try:

  • Set the thermostat to Heat, above room temp, and replace batteries if needed.
  • Verify the furnace switch and breaker are on; reset a tripped breaker once.
  • Swap a dirty filter and open all supply and return vents.
  • If you smell gas or see burned wiring, leave and call emergency services.

If these steps don’t restore heat, book a diagnostic so a tech can test igniters, sensors, and controls safely.
