Are you considering a mini split system to cool and heat your home in Rhode Island or Southeastern Massachusetts? Wondering about mini split installation cost and what’s included?
At Armus Mechanical, we help local homeowners make smart decisions about ductless HVAC upgrades. In this guide, we’ll explain how mini split systems work, break down costs, cover available rebates, and outline what to expect—from your first call to final installation.
What is Mini Split Installation Cost & How Does It Work?
Mini split installation cost refers to the total price of purchasing and professionally installing a ductless mini split HVAC system. A mini split includes one (or more) indoor air handling units connected to an outdoor condenser. Unlike central air systems, mini splits don’t require ductwork, making them perfect for older homes, additions, or rooms where ducts aren’t practical.

System Selection: You choose the right mini split model—single zone or multi-zone—for your comfort needs.
-
Installation: Our team mounts the indoor and outdoor units, connects refrigerant and power lines, and tests the system.
-
Final Walkthrough: We review operation and maintenance tips with you.
