Tankless Water Heater Descaling Service in Meridian
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Much of the water in Mississippi comes from underground aquifers and is fairly soft, though some supplies carry iron or a sulfur smell. Our descaling service in Meridian involves flushing the unit with a specialized 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.
Tankless Repair vs Replacement Cost in Meridian, MS
Descaling service usually costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed typically ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

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.
Gas Tankless Water Heater Repair in Meridian
