How much does it cost to replace a ductless mini split system?

Replacing a ductless mini-split is priced after an in-home assessment because equipment size, zone count, efficiency, and installation conditions determine the total. Most of the price comes from matching the outdoor unit’s capacity to your home and how many indoor heads you need. We install and replace ductless systems for homeowners throughout the Salem area. After the visit, Wisler provides clear, fixed pricing before any work begins. A two-zone upgrade often runs higher because each head needs its own refrigerant line, drain, and control wiring.

When we quote your system, we typically account for:

• Number of indoor heads (zones) and outdoor unit BTU capacity
• Efficiency level (SEER2/HSPF2) and brand options you select
• Install details like line-set length, wall vs. ceiling placement, and condensate removal
• Electrical and mounting needs such as circuits, pad/stand, or wall brackets

An on-site evaluation confirms sizing and gives you a firm, itemized price with no surprises.
