Tankless Water Heater Descaling Service in Auburn
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Private wells serve a large share of Maine homes, and arsenic, radon, and iron make regular well water testing important.

This preventative maintenance and repair step is key for extending the lifespan of your tankless heater and keeping it at peak performance.

Condensing Tankless Repair in Auburn, ME
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.
