Mini split ac installation — Seattle, WA

Last updated: September 24, 2026

What affects the price

When you look at the cost of a new HVAC system, several variables come into play. The size of your home and the necessary cooling or heating capacity—measured in tons—are the biggest factors. You also have to consider the efficiency rating of the unit, the complexity of your existing ductwork, and whether you need to upgrade electrical components to support a modern system. Labor requirements, including accessibility and permit fees, further influence the final number.

About this service

A mini-split installation is ideal for homes without ductwork or for adding climate control to specific rooms like garages or additions. The process involves mounting an indoor air handler and connecting it to an outdoor compressor through a small hole in the wall. You need this if you want room-by-room temperature control or a highly efficient alternative to traditional central air. It is a quiet, flexible solution that avoids the need for bulky metal ducts throughout your home.

Summer is peak season for HVAC, so if your system is struggling, it is best to act as soon as you notice a performance drop. While demand is high, our routing service helps you find available local professionals quickly. Don't suffer through the heat; let us help you find a prompt solution.
