Frisco's rapid growth means most of its housing stock was built in the last 20 years — and water heaters in newer construction are commonly tankless units or high-efficiency tank models. Even newer equipment fails: error codes, scaling from North Texas hard water, and fitting failures are among the most common calls we receive from Frisco.
NTMWD water runs around 150–180 mg/L in Frisco. That mineral content scales tankless heat exchangers and tank floors faster than residents expect. Tankless units in Frisco typically need descaling within 12–18 months of installation to maintain rated efficiency. We diagnose the underlying cause — not just the symptom — before quoting any repair.
