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.”

Why Choose Fireplace Installation

Gas Fireplace Options

Modern gas fireplaces are a far cry from the pilot-light-driven units of decades past. Today's models offer realistic flames, high heat output, precise temperature control, and a variety of design styles that complement any interior. QC Mechanical installs both traditional and contemporary gas fireplaces from Heat n Glo and Montigo.

Gas fireplaces provide more than ambiance — they deliver real supplemental heat. A quality gas fireplace can heat a large living space efficiently, reducing demand on your primary HVAC system during the shoulder seasons. With thermostat or remote control, you can dial in exactly the warmth you want.

  • Heat n Glo traditional and contemporary gas fireplaces
  • Montigo custom and linear fireplace designs
  • Direct vent, B-vent, and vent-free options (where code permits)
  • Remote control, thermostat, and wall switch operation
  • Supplemental zone heating to reduce primary HVAC demand
  • Realistic flame technology for natural fire appearance

Installation: What Is Involved

Installation: What Is Involved

Gas fireplace installation requires expertise in gas line work, venting, framing, and finish carpentry. QC Mechanical handles the mechanical scope of the installation — gas supply, venting through the wall or roof, electrical connections, and unit setup — ensuring everything meets local building codes and manufacturer specifications.

Direct-vent fireplaces are the most common configuration for Pacific Northwest installations. These units draw combustion air from outside and exhaust through a concentric vent pipe, making them safe and efficient for tight, well-insulated homes. For existing homes, we evaluate the proposed installation location, determine the most practical venting route, and verify gas supply capacity.

  • Gas line sizing, routing, and connection
  • Direct vent, B-vent, and power vent configurations
  • Framing and fire-stop installation per code requirements
  • Electrical connection for ignition, blower, and controls
  • Coordination with builders on new construction projects

Our Fireplace Installation Process

Consultation and Design We discuss your fireplace goals — ambiance, supplemental heat, or both. We help you select a model that fits your space, design style, and budget.
Site Evaluation Our technician assesses the proposed installation location, determines the best venting route, checks gas supply capacity, and identifies any structural considerations.
Detailed Proposal You receive a written proposal covering the fireplace unit, gas line work, venting, electrical, and installation labor. We outline what is included and what finish work may be needed.
Gas and Vent Rough-In We run the gas line, install venting through the wall or roof, and complete any required framing or fire-stop work before the fireplace unit is set.
Fireplace Installation The fireplace unit is set in place, connected to gas and venting, wired for ignition and controls, and tested for proper operation and safety.
Final Inspection and Walkthrough We verify gas pressure, combustion performance, and venting operation. We walk you through the controls, maintenance requirements, and warranty coverage.
