Answers to Common Questions
View All FAQsWhat Should I Do If My Heater Is Not Working in My House?
If your home heater isn’t working, set the thermostat to Heat, make sure it’s above room temperature, check the breaker, and replace a dirty air filter, then call a licensed HVAC technician if it still won’t run. Most no-heat issues stem from a tripped breaker, a clogged filter restricting airflow, or an ignition/control fault inside the furnace. A technician can test safeties and ignition parts and tell you whether a focused repair or planning for replacement makes more sense. We handle no-heat visits across Corona Del Mar and include a carbon monoxide safety check with heating work. Emergency and same-day help is available 24/7.
Before you book, try these quick checks that often restore heat:
- Put the fan setting to Auto, not On, to prevent constant cold airflow.
- Replace thermostat batteries and confirm the date/time if it’s programmable.
- Ensure the furnace door panel is fully latched so the safety switch engages.
- Open supply and return grilles; don’t block the furnace intake.
If you smell gas or your CO alarm sounds, leave the home and call emergency services before anything else. <br/> Updated: 2026-04-05 <br/> Need help in Corona Del Mar, CA? Call (833) 687-0145 or book online.
