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 heat pump installation & replacement, bring gas-to-electric conversion into the scope discussion. Compare single-stage, two-stage and variable-capacity choices by approved system match, room comfort, sound and total scope. Do not assume the largest rebate identifies the most suitable system or that expected energy savings are guaranteed.
