What's My System's Warranty Coverage?

Not sure if you have the standard warranty, less, or more? Check your system's warranty coverage with the unit's serial number. This is located on the sticker attached to the side of the unit and it starts with "M."

TETCO's Standard Commercial Warranty

All internal system components of the geothermal or water-source heat pump are covered for one year.


TETCO geothermal heat pumps and system installations may include electrical, refrigerant and/or water connections. Federal, state, local codes and regulations apply to parts of the installation process. Equipment that isn't installed or serviced properly can lead to unit failure and health/safety concerns. For these reasons, only qualified technicians should install, diagnose, or service a TETCO geothermal system.

Due to the importance of proper installation and service, TETCO does not sell equipment directly to home or building owners. Internet websites and HVAC outlets may allow for purchase directly by homeowners for a DIY approach, but TETCO  does not offer any warranty coverage on equipment that is purchased online or installed or serviced by persons without Enertech-approved training.

TETCO has set forth this policy to ensure that work relating to our systems is done properly, to code, and with safety in mind. Using well-trained, qualified technicians to install and service TETCO geothermal systems helps ensure your system lasts for its expected lifetime, providing comfort and savings throughout.

* Warranty is subject to change per TETCO system. Look at individual product pages for details on the specific warranty available for that system and discuss warranty options with your local installer.
