What we build, install and service

Industrial Heating, Ventilation & Air Conditioning Systems

Industrial heating, ventilation and air conditioning systems are at the center of what we do. We fabricate and install process exhaust, dust and fume collection, and make-up air systems for industrial shops, maintenance facilities and treatment plants. We build to SMACNA industrial duct standards in galvanized, stainless, aluminum and FRP, and we handle the fans, collectors, controls and power that make the system run.

• Process, fume and welding exhaust
• Dust collection systems
• Industrial welded ductwork
• Make-up air and large louvers
• Tunnel and pump station ventilation
• Gas-fired make-up air and heating equipment, with gas piping

Odor Control Systems

We have installed odor control at wastewater treatment plants, pump stations and lift stations across Puget Sound, including a long run of work for King County and the City of Seattle. Our crews set carbon vessels and scrubbers, install large-diameter FRP and stainless foul-air duct, and connect fans, dampers and actuators. Our people helped write the FRP duct training used by Sheet Metal Workers Local 66 and teach it.

• FRP (thermoplastic and fiberglass) foul-air ductwork
• Welded stainless steel duct
• Carbon, chemical and biological scrubbers
• FRP fans, dampers and actuators
• Field lamination and repairs

Refrigeration & Precision Cooling

Refrigeration is a large part of our work. Our EPA-certified technicians install and start up precision cooling and heating for critical infrastructure projects, including computer room air conditioning, process cooling and heating systems, split system heat pumps, VRF, walk-in coolers, water chillers and air-to-water heat pumps, along with the refrigerant piping that ties them together. We also service what we install.

• Computer room air conditioning for precision cooling
• Process cooling and heating systems
• Split system heat pumps
• VRF / VRV systems
• Walk-in coolers
• Water chillers and air-to-water heat pumps
• Refrigerant piping, evacuation and start-up

Commercial HVAC

We install complete HVAC systems for military facilities, schools, public buildings and commercial owners. We work plan-and-spec and design-build, and our in-house BIM group models and coordinates our systems in Revit and Navisworks before anything is fabricated. We also install and maintain gas-fired HVAC equipment, including the gas piping systems.

• Air handlers, rooftop units and heat pumps
• Gas-fired furnaces, unit heaters and rooftop units, with gas piping
• Supply, return and exhaust ductwork
• Commercial kitchen hoods and exhaust
• Design-build and BIM coordination
• Testing, start-up and owner training

Equipment Retrofit & Replacement

A lot of our work is retrofit and replacement of existing equipment. We remove old, worn-out units and install the new ones in buildings that have to stay in use, including large equipment changeouts that need cranes and rigging. When a space cannot go without cooling or heating during the changeout, we provide temporary systems to carry it until the new equipment is running.

• Replacement of air handlers, rooftop units, chillers, condensing units, heat pumps and gas-fired equipment
• Large equipment changeouts with crane and rigging
• Temporary cooling and heating during changeouts
• Proper removal, disposal and recycling of old equipment and refrigerants
• Work in occupied and operating facilities, including on base
• Start-up, testing and owner training on the new equipment

Design-Build & Design-Assist

We deliver projects design-build, design-assist and plan-and-spec. On design-build and design-assist work we join the team early to help lay out the systems, select equipment, check constructability and keep the budget on track. Our in-house BIM group models and coordinates the work in Revit and Navisworks, and our estimators price it as the design develops.

• Design-build mechanical systems
• Design-assist and preconstruction support
• Budgeting and estimating during design
• Constructability review and value engineering
• BIM modeling, coordination and shop drawings

Controls & Electrical

We hold our own Washington electrical contractor license, so the power and control wiring for our mechanical systems stays in one contract. Our electricians hold Washington 01, 06 and 06A certifications. DDC control systems are installed by our controls subcontractors, or in house as pre-packaged systems from the equipment and controls suppliers. We also install variable frequency drives, actuators and the line and low voltage wiring that serves them.

• HVAC power and control wiring
• DDC systems, subcontracted or pre-packaged
• Variable frequency drives
• Damper and valve actuators

Shipboard Ventilation Ductwork

We fabricate shipboard ventilation ductwork for the ship repair and modernization contractors working aboard aircraft carriers and other Navy vessels in port at Puget Sound Naval Shipyard and Naval Base Kitsap. Bring us the old ship vent pieces and we will build their replacements, or send us your drawings and we will fabricate to them. If you need measurements, we will come to your shop, the pier or aboard the ship and take them ourselves. We build ship vent in aluminum, galvanized and stainless steel, welded or seamed, or in any other material you specify, and we can install it if requested. Our shop is minutes from the Bremerton gate. For a quote, call Rick Ablitt at (360) 479-1737 ext. 128.

• Ship vent pieces for aircraft carriers and other vessels in port
• Replacements built from your old vent pieces
• Fabricated to your drawings
• Measurements taken at your shop, on the pier or aboard ship
• Aluminum, galvanized and stainless steel, welded or seamed
• Any other material you specify
• Installation if requested

Custom Fabrication & Welded Ductwork

We do custom fabrication of all types. Our shop fabricates what our own field crews install, and it also builds for other contractors and owners who need fabricated items for industrial work. Our largest line of fabrication is shipboard ventilation ductwork for ship repair contractors, which has its own section above. If you need custom fabrication of any kind, call our office at (360) 479-1737 and we will assist you. Our shop is open to the public. We work in galvanized, stainless, aluminum and copper, and our welders are certified in MIG and TIG.

• Industrial welded ductwork and plenums
• Stainless, aluminum and copper work
• Exhaust hoods and enclosures
• Architectural sheet metal
• Spiral and rectangular duct
• Fabrication only, for others to install

HVAC Service & Repair

Our service technicians start up, troubleshoot and repair commercial and industrial HVAC and refrigeration equipment, and they support every project we build through the warranty period. They are factory trained on Mitsubishi and Daikin VRF systems.

• Equipment start-up and commissioning support
• Troubleshooting and repair
• VRF, rooftop, heat pump and computer room units
• Gas-fired HVAC equipment and gas piping
• Warranty service on MSM projects
