- Ignition and flame-sensing checks
- Venturi and combustion-air inspection

Urgent Tankless Repair Questions
Do you guarantee same-day service?
No. Urgent appointments depend on the current schedule. Call or text and Dustin will tell you the earliest available time.
Does no hot water always mean the unit needs replacement?
No. Shutdowns can be caused by maintenance conditions, ignition problems, airflow or venturi issues, sensors, wiring or failed components. Diagnosis should come before a replacement recommendation.
Can a flush restore a tankless heater that stopped working?
Sometimes, when scale or a maintenance-related lockout is the cause. A flush is not the automatic solution for every error code or no-hot-water condition.
What if I smell gas or a carbon-monoxide alarm sounds?
Leave the area and contact the gas utility or emergency services from a safe location. Do not wait for a normal repair appointment.
