If asbestos is discovered during removal/installation of existing heating system/piping, the customer will be responsible for the removal of all asbestos impacting the project and the additional charges incurred by the abatement service.


Tetra will return full deposit if project is cancelled before installation date. If the installation cannot occur due to no fault of the Homeowner, InHome will refund the full deposit.
