David K.

Tech: Jason T.

“We had a new central AC system installed before summer hit. The crew was respectful of our home, cleaned up after themselves, and the system runs perfectly. Great experience from start to finish.”

Linda & Tom P.

Tech: Carlos D.

“Been using QC Mechanical for annual maintenance on our commercial building for three years. They are always thorough, honest about what needs attention, and fairly priced. Trustworthy company.”

James W.

Tech: Mike R.

“QC Mechanical helped us choose and install a ductless mini-split system for our addition. The installation was clean and efficient. The system heats and cools perfectly. Would absolutely use them again.”

Rachel G.

Tech: Jason T.

“We needed a full HVAC system for our new construction home in Puyallup. QC Mechanical worked directly with our builder and had everything installed on schedule. The system is quiet, efficient, and perfectly sized for our layout.”

Mark & Jennifer B.

Tech: Brian L.

“Had a Heat n Glo fireplace installed in our living room. The team handled everything from the gas line to the finish trim. It looks incredible and puts out serious heat. Really happy with the result.”

Greg H.

Tech: Carlos D.

“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.

Tech: Sarah K.

“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.

Tech: Jason T.

“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 & Steve D.

Tech: Brian L.

“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.

Tech: Mike R.

“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.”

Our Story

Built on Doing the Right Thing

QC Mechanical was founded on a simple principle: treat every customer the way you would want to be treated. For over 25 years, that commitment has guided every decision we make — from the technicians we hire to the brands we carry to the way we communicate with our customers.

[PLACEHOLDER — Owner/founder narrative goes here. This section should include the founder's name, their background in the HVAC trade, what motivated them to start QC Mechanical, and their personal commitment to the craft. The Titan reference model shows this as a first-person narrative that is specific, credentialed, and human.]

What started as a commitment to honest work has grown into a full-service HVAC operation serving four counties in Washington State. We handle everything from new construction systems and commercial installations to emergency repairs and preventive maintenance — and we bring the same level of care to every job, regardless of size.

We earned our Mitsubishi Diamond Dealer status through consistent excellence in installation quality and customer satisfaction. Our technicians hold EPA and NATE certifications because we believe the people working in your home or business should be the best in the field. We do not cut corners. We do not oversell. We assess your situation honestly and recommend what actually makes sense for your needs and budget.
