Rinnai America Corporation

Rinnai America Corporation operates as the U.S. corporate office for a global tankless water heater manufacturer headquartered in Peachtree City, Georgia. The company maintains a 2.6-star rating across 41 customer reviews, with service hours extending Monday through Friday from 8 AM to 5 PM. As a corporate entity rather than a field service contractor, Rinnai supports residential and commercial customers through a network of authorized installation professionals located throughout the Southeast region, including Georgia and South Carolina markets.

What distinguishes Rinnai from standalone HVAC contractors is the company's manufacturing pedigree and international support infrastructure. The Peachtree City location serves as the North American hub for a brand with roots in Japan, Korea, and multiple Southeast Asian markets. This corporate office handles warranty claims, product registrations, and technical support for tankless units including the RXP and DUO series, while directing homeowners to certified plumbers for installation and servicing rather than providing on-site repairs directly.

Customer reviews reveal specific warranty handling scenarios that prospective buyers should evaluate. One reviewer documented a temperature sensor failure on an RXP199iN unit after ten months, with warranty coverage disputes arising once the unit was removed from wall mounting. Another reviewer, a plumbing professional who purchased over 50 residential units across a decade, described ongoing reimbursement delays exceeding three months for labor warranty claims. These accounts suggest warranty processes may involve documentation requirements that extend beyond typical residential expectations.
