We test the pump, check valves and controls and set the schedule to match your daily routine. A properly tuned system saves both water and gas.

Condensing Tankless Repair in North Miami, FL

Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate.

PVC venting is also checked for slope and sagging.

Tankless Water Heater Descaling Service in North Miami

Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Water across much of Florida comes from limestone aquifers and runs hard, leaving stubborn scale on fixtures and inside water heaters. Our descaling service in North Miami involves flushing the unit with a dedicated cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.

No Hot Water Tankless Repair in North Miami

When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger. Our technicians in North Miami will thoroughly diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup. We carry common replacement parts for fast fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.

Flow Sensor and Thermistor Repair in North Miami

Tankless heaters use flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace failed parts. Temperature becomes steady again once readings are correct.
