“Upgraded from a traditional tank to a Rinnai tankless water heater. CrestLine handled the gas line modifications, venting, and electrical. Endless hot water now and our gas bill dropped noticeably. They walked us through the maintenance schedule too. Very knowledgeable.”

“Our 15-year-old water heater started leaking on a Sunday. CrestLine came out Monday morning, removed the old unit, and installed a new 50-gallon Rheem with an expansion tank and new flex lines. Hot water by lunchtime. They even disposed of the old unit. Emergency service done right.”

“Our 15-year-old water heater started leaking on a Saturday. Called CrestLine and they had a new 50-gallon Rheem installed by Monday afternoon. They disconnected the old one, hauled it away, and updated the gas connector. Hot water restored and peace of mind too.”
