Common causes include low flow, a clogged inlet filter, mineral buildup in the heat exchanger, a failing sensor, or ignition and venting issues. We diagnose the root cause and restore stable hot water safely.

Most homes benefit from annual descaling and inspection. If hot water use is high or mineral content is higher, yearly service helps prevent error codes, improves flow, and protects efficiency.

Sometimes. Many tankless units require higher BTU input and specific venting and airflow. We check your current setup and explain any required upgrades clearly before any work begins.

If your unit needs frequent repairs, has recurring error codes, is leaking, or cannot maintain stable temperature and flow, replacement can be the better long term value. We provide honest options based on condition and total cost.
