What is the payback period for a mini-split?

Replacing electric resistance heat with a mini-split heat pump typically pays back in 2-5 years. Replacing gas in regions with cheap gas may take 8-15 years.

How much does a mini-split system cost?

Single-zone mini-splits cost $700-$2,000 for the unit plus $1,000-$2,500 installation. Multi-zone systems: $3,000-$7,000 for equipment plus labor.
