(b) the owner of the geothermal ground-coupled heat pump system may bear the actual cost of shipping the product for the repair and replacement;

(3) be a complete system that collects and distributes geothermal energy to the residence, business or agricultural enterprise in New Mexico that it serves; and

(4) be a minimum one-ton system size.

B. Geothermal ground-coupled heat pump systems or their portions that the department shall not certify are as follows:

(1) a system or portion of a system that would be present if the geothermal ground-coupled heat pump system was not installed;
