The Manufacturer Warranty (typically a 7-year warranty for top-tier brands like Rinnai, Carrier, and Toshiba ) covers the physical air conditioning machine and its internal components. The Installation Warranty is provided directly by Ample Air and covers our workmanship—this includes the copper pipework, electrical wiring, and ducting. Because Ample Air has been operating since 1982 , you have the peace of mind knowing we will be here to honor both our work and your service needs years down the line.
