Mayeux's AC & Heating has operated out of Norco, Louisiana since 1985, serving St. Charles Parish and the River Parishes corridor along the Mississippi River. The company holds LSLBC contractor license #23760, Lennox Premier Dealer status (verified on Lennox's residential dealer locator), and EPA and NATE certifications. Dwayne Mayeux, the company's namesake principal, has served as past president of the Associated Builders and Contractors (the company has been a member for more than 30 years). The company's dedicated geothermal page covers two standard system types — open-loop (groundwater via well, pond, or lake) and closed-loop — with closed-loop installation options including horizontal, slinky, and vertical configurations. The firm also handles whole-house generator systems under the Kohler and American Standard factory-service lines. Lennox markets a current Ultimate Comfort System line; Mayeux's geothermal services span legacy system maintenance and current Lennox heat-pump installation.
