Compare conversion details, not only the rebate
Heco's documented Antelope project replaced an older gas-electric split system with a 4-ton Star Air Kontrol all-electric heat-pump system. That job illustrates a conversion approach; it does not establish the size or rebate for another property.
For your own proposal, compare the load calculation, exact model pairing, indoor unit location and electrical requirements. Ask which measures qualify for the utility program and keep the gross project cost separate from the expected incentive.
For vrf / vrv systems, bring gas-to-electric conversion into the scope discussion. Discuss the specific fault, compatibility and service support before comparing repair with alteration or replacement. Keep unsupported equipment and chiller systems outside the promised scope.
