The Work

As an HVAC Mechanical Pipe Welder, you will be responsible for the installation, modification, maintenance, and removal of commercial HVAC piping systems and related mechanical equipment. You will work from mechanical drawings, specifications, isometric drawings, and project plans while following established safety and quality requirements.

Typical responsibilities include:

Fabricating, assembling, and installing hydronic, chilled water, and heating water piping systems
Installing and connecting piping to chillers, boilers, pumps, heat exchangers, air-handling equipment, and other mechanical systems
Measuring, cutting, threading, grooving, fitting, and assembling various types of pipe
Working with steel, copper, and grooved piping systems
Reading and interpreting mechanical drawings, blueprints, isometrics, specifications, and layouts
Installing pipe supports, hangers, valves, fittings, and related components
Rigging, positioning, and setting mechanical equipment and piping components
Performing demolition and removal of existing HVAC piping, equipment, and mechanical systems
Performing pressure testing and assisting with system flushing, startup, and commissioning activities
Identifying potential installation issues and communicating them to supervisors or project management
Maintaining proper alignment, slope, and support of piping systems
Working safely around operating equipment, construction activities, lifts, scaffolding, and other trades
Maintaining a clean, organized, and safe work area
Following all company, contractor, client, OSHA, and job-site safety requirements
Working cooperatively with other pipefitters, welders, electricians, HVAC technicians, and construction trades
Performing other pipefitting and mechanical construction duties as assigned

Required Qualifications

3+ years of professional pipefitting experience, preferably with commercial HVAC or mechanical construction experience
Strong understanding of commercial HVAC piping systems
Experience working with steel, copper, and grooved piping
Ability to read and work from blueprints, mechanical drawings, isometric drawings, and specifications
Ability to accurately measure, cut, thread, groove, fit, and install pipe
Experience with mechanical equipment installation and piping connections
Own standard hand tools required for the pipefitting trade
OSHA 10 certification required; OSHA 30 preferred
Ability to lift up to 50 pounds
Ability to work at heights, in confined/tight spaces, and in varying outdoor conditions
Ability to work a full 4x10 schedule
Strong commitment to safety, quality, and following job-site procedures

IMPORTANT: Extensive Onboarding, Background Check & Drug Testing

Please read this section carefully before applying.

Because these pipefitters will be working on high-security commercial and federal-related job sites, the onboarding process is significantly more extensive than a typical construction position.

Candidates must successfully complete all required screening and onboarding requirements before they are permitted to begin work. This may include:

Extensive background checks conducted by the client
Pre-employment drug testing
Employment and/or work history verification
Identity and eligibility verification
Client-specific security and site-access screening
Completion of required safety and site orientations
Completion of all required employment and project documentation
Obtaining special site-specific badging or credentials required for access
Additional screening or requirements imposed by the client or individual job site

Passing the initial hiring process does not guarantee immediate site access. Candidates must receive all required client approvals and credentials before reporting to the job site.

Candidates should be prepared for the possibility that the onboarding and clearance process will take longer than a standard construction hiring process. No candidate will be permitted to begin work until all required background checks, drug testing, badging, and onboarding requirements have been successfully completed.

Preferred Qualifications

The following experience or certifications are preferred but not required:

Welding and/or brazing certifications
Chiller installation or replacement experience
Boiler installation or replacement experience
Experience working on Davis-Bacon or other federally funded projects
Experience with large commercial mechanical systems
Rigging experience
Aerial lift certification
Forklift certification
Confined-space experience
Experience working on federal, military, government, or other security-controlled job sites

What We're Looking For

We are looking for dependable, experienced pipefitters who understand commercial HVAC mechanical work and can perform safely and efficiently in a highly regulated job-site environment.

The ideal candidate is comfortable working from drawings and specifications, has strong mechanical aptitude, takes pride in quality workmanship, and understands the importance of following strict safety and site-access procedures.

If you are interested in the position, please be prepared to provide accurate employment and work-history information and complete all required screening and onboarding steps.
