Air Conditioning Prices in Seattle

Air conditioning in Seattle starts from $100. A split system supply and install averages $5000. Prices exclude sales tax. Includes standard installation; complex installs may cost more.

Split systems are ideal for cooling one or two rooms and cost $3000–$7500 installed. Ducted systems cool the whole home but cost significantly more. For multiple rooms without ductwork, a multi-split system is a good middle ground.

A standard split system installation takes 3–5 hours. Multi-split systems take 1–2 days. Ducted systems typically require 2–5 days depending on the size of the home and whether new ductwork is needed. Book well ahead of summer for the best availability and pricing.

Running costs depend on the system size, efficiency rating, and usage. A typical split system costs $0.30–$0.80 per hour to run. Higher star ratings and inverter technology significantly reduce running costs. Regular servicing maintains efficiency and keeps running costs down.
