Do you guys take on tankless water heater repair jobs?
I do mostly drywall patching, fence repair, and basic fixture swaps. Lately, I’ve had a ton of clients asking me to descale or fix their Rinnai and Navien tankless units. I usually pass on tankless water heater repair because the electronics seem finicky and I'm not a licensed plumber. Should I learn how to do this, or is the liability too high for a general handyman?
