Tankless Water Heater Descaling Service in Farmington Hills
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Homes around Farmington Hills on private wells usually benefit from a water test before picking a softener, since mineral levels vary widely. Our descaling service in Farmington Hills 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.
Ignition Failure Repair in Farmington Hills, MI
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Condensing Tankless Repair in Farmington Hills, MI
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and confirm proper drainage. PVC venting is also checked for slope and sagging.

Modern tankless water heaters display error codes to indicate specific problems, from flow rate issues to combustion errors. Our experts in Farmington Hills, MI are trained to interpret these codes accurately, using dedicated diagnostic tools to pinpoint the exact component failure. This precision allows us to quickly order the correct parts and perform targeted repairs, saving you time and money.
