Tankless water heater installation for Austin homes — on-demand hot water, lower energy use, and longer service life. Call (512) 444-4444 to schedule a consultation. Austin's hard water is the primary reason Austin homeowners switch to tankless — and annual descaling maintenance is required to keep tankless units running efficiently in Austin's hard water environment.
Tired of running out of hot water — or looking to reduce energy bills from a tank unit that's been running 24/7 for 12 years. A tankless water heater provides hot water on demand and lasts 15–20 years with proper maintenance.
Austin's hard water (200–400 ppm) is the primary reason Austin homeowners switch to tankless water heaters. Scale buildup reduces tank water heater efficiency by 20–30% over 5 years. Tankless units require annual descaling maintenance in Austin's hard water environment — we explain this upfront so there are no surprises. Gas tankless installations require a permit if gas line work is involved.

"Kitchen drain was completely blocked. They came out, diagnosed it as a grease buildup 20 feet down the line, and cleared it the same day. Explained exactly what they found. Fair price, no upsell pressure."

"Water heater stopped heating on a Thursday. They had a replacement installed by Friday afternoon. Walked me through the options without pushing the expensive unit. Exactly what you want from a plumber."
