Ductless Mini-Split Installation Cost & Multi-Zone Design Strategies

Ductless mini-split heat pumps provide individualized temperature control for rooms without ductwork, older homes, and bonus spaces. Installation costs depend on line set length, wall head mounting height, electrical panel capacity, and multi-zone branch boxes.

Single-zone mini-splits typically range from 9,000 to 24,000 BTUs with wall-mounted or flush ceiling cassette options. Multi-zone outdoor compressors can power up to eight indoor heads with independent climate scheduling.

Line set aesthetic covers (Slimduct) protect refrigerant piping and electrical cabling while matching your home's exterior finish. Proper condensate drainage tubing or mini condensate pumps prevent water damage.

Always hire a licensed HVAC contractor who performs nitrogen pressure testing, deep vacuum evacuation to below 500 microns, and weigh-in refrigerant charging.
