Lennox Warranty

Lennox Comprehensive Product Warranty for Residential Applications

For residential applications, all Lennox residential products come with a 5-year parts and a 5-year labour warranty (limited only by the requirement for installation, commissioning, operation and maintenance in accordance with the relevant Lennox guidelines and Terms and Conditions of Sale).

For residential applications, Lennox gas ducted heaters also carry a 10-year parts only warranty on the heat exchanger, the heart of all ducted heaters. The use of premium components and stringent quality control procedures provide owners with unparalleled peace of mind.

Lennox Comprehensive Product Warranty for Commercial Applications

For commercial applications, we warrant that your Lennox equipment will deliver its rated heating and cooling capacity when installed, commissioned, operated and maintained in accordance with Lennox guidelines as detailed in the relevant Lennox documentation and Terms and Conditions of Sale.

If, within 2 years of the date of original invoice, any part of your new Lennox equipment fails because of a manufacturing defect, Lennox will supply a replacement part free of charge, provided that the equipment has been installed, commissioned, operated and maintained in accordance with the relevant Lennox guidelines and Terms and Conditions of Sale.

Warranty Service

To get your unit repaired under this warranty contact your Installer or your nearest Kirby HVACR office by calling 13 23 50 in Australia or 0800 653 330 in New Zealand. Your proof of purchase and installation by a licenced installer must be available to be presented.

If your unit will not operate – complete the following checklist before you call for service;

  • Check operation of the remote control and that the batteries are in charged condition
  • Is the fuel/power turned on and available?
  • Clean the filter
  • Some products are equipped with manual lockout or manual reset devices. Reset if necessary. Check with your installer or operating instructions.
    CAUTION: Do not reset more than once. If the unit continues to malfunction, call your service agent.

When calling your local service agent be prepared to supply them with the complete model number of the equipment, along with the serial number and installation date. Also be prepared to give them an accurate description (as best you can) of the problem.
In order to maintain high efficiency in operation and conserve energy use, we recommend an annual maintenance program. Such programs are available from your Lennox Dealer and will help increase the serviceable life of the product and your investment. Talk to your Dealer/Installer for more information and to explain the benefits of an annual PLANNED SERVICE AGREEMENT.
