What Our Customers Say

Real feedback from homeowners and businesses across the Puget Sound region.

“Our 20-year-old furnace finally gave out. QC Mechanical recommended an American Standard unit that fit our budget. The old system was out and the new one was running in the same day. Very impressed.” 

Patricia S

“I manage a restaurant in Federal Way and our rooftop unit went down during a busy weekend. QC Mechanical had a tech out within hours and got us back up and running. That kind of response time is why we keep calling them.”

Tony R

“We upgraded from an old baseboard heating system to a Mitsubishi ductless setup. The difference in comfort and our energy bills is night and day. QC Mechanical walked us through every option and never pushed us toward the most expensive one.”

Angela D

“Signed up for their annual maintenance plan after they serviced our AC last summer. The fall tune-up caught a cracked heat exchanger before it became a safety issue. Glad we have them keeping an eye on things.”

Robert N.

“QC Mechanical handled the HVAC for our four-unit apartment building in Tacoma. They designed a system that keeps all the tenants comfortable without breaking the bank on energy costs. Professional crew from start to finish.”
