296 AC Installation Contractors in Portland, OR

AC Installation in Portland is growing faster than the contractor market has scaled to meet it. The city's mild Mediterranean climate long made cooling an afterthought, but heat waves pushing past 100°F have accelerated AC adoption across a housing stock that was built without it. Fifty-four contractors now serve the Portland AC installation market at a 4.7 average from 19,962 reviews. Thirteen offer 24/7 access, though installation work is typically scheduled in advance.

Window units run $138 to $644 installed. Ductless mini-splits — the dominant solution for homes without existing ductwork — land at $1,840 to $7,360 per zone. Central AC replacement into existing duct systems runs $3,220 to $11,040. Oregon requires the Limited Journeyman HVR license plus CCB contractor registration for all installation work, and active contractors must carry both.
