Why it matters to you
For Lowcountry homes that already have gas service, dual fuel keeps heat pump efficiency for the mild majority of winter while gas covers the few genuinely cold snaps. Berkeley Electric Cooperative offers rebates for qualifying dual-fuel installations.
Practical guidance
Dual fuel fits best when a working gas line and venting are already in place. Have the switchover temperature set during commissioning based on your equipment and utility rates rather than a factory default.
