What Does a Welder Do?
Welders join and repair metal structures using specialized equipment and welding techniques. Welding is used across industries such as construction, manufacturing, aerospace, shipbuilding, and energy. According to the Bureau of Labor Statistics (BLS), manufacturing employs 63% of welders.
Common welding responsibilities include:
- Reading blueprints and technical diagrams
- Operating welding equipment
- Fabricating metal components
- Repairing structural systems
- Inspecting weld quality
- Following industrial safety procedures
Welders may specialize in:
- Structural welding
- Pipe welding
- Underwater welding
- Aerospace welding
- Industrial fabrication
Many welding jobs involve physically demanding work environments.
What Does an HVAC Technician Do?
HVAC technicians install, repair, and maintain heating, ventilation, air conditioning, and refrigeration systems.
Common HVAC technician responsibilities include:
- Installing HVAC systems
- Diagnosing mechanical problems
- Repairing air conditioning units
- Maintaining heating systems
- Testing system performance
- Working with electrical and refrigeration systems
HVAC technicians work in residential, commercial, and industrial settings.
New construction, aging systems that need replacing, and growing interest in energy-efficient heating and cooling continue to drive demand for HVAC work.
Training Requirements
Both welding and HVAC careers typically involve trade school training, apprenticeships, or technical certifications rather than traditional college degrees. The official entry requirements differ, though.
Welding Training
The BLS lists a high school diploma as the typical entry-level education for welders, followed by moderate-term on-the-job training. In practice, many employers prefer to hire workers who have completed a program at a vocational-technical institute, community college, or private welding school, and some offer employer-based apprenticeships.
Welding programs often take:
- 6 months to 2 years
Students commonly learn:
- MIG welding
- TIG welding
- Stick welding
- Blueprint reading
- Metal fabrication
- Welding safety
Many welders also pursue industry certifications through the American Welding Society (AWS). The AWS Certified Welder test has no prerequisite courses—it’s a hands-on, performance-based test taken at an AWS Accredited Test Facility. The BLS notes that some employers require certification, and some states and localities require welders to be licensed.
HVAC Training
According to the BLS, the typical entry-level education for HVAC technicians is a postsecondary nondegree award, followed by long-term on-the-job training. Many technicians also complete apprenticeships, which the BLS says usually last several years.
HVAC programs also typically take:
- 6 months to 2 years
Students usually study:
- Refrigeration systems
- Electrical systems
- HVAC installation
- Diagnostics and troubleshooting
- Climate control systems
- HVAC safety procedures
The BLS notes that the Environmental Protection Agency requires nearly all HVAC technicians to be certified in proper refrigerant handling under EPA Section 608. Some states and localities also require HVAC technicians to be licensed.
What Training Costs
Both trades are commonly taught at community colleges and private trade schools. According to the National Center for Education Statistics (NCES), average tuition and required fees at public two-year colleges were about $4,200 a year for in-district students in 2024–25, compared with about $17,000 a year at private for-profit two-year schools. A roughly one-year certificate costs about one year of tuition, plus tools, gear, and certification test fees.
Salary and Career Growth
Both trades can offer solid earning potential depending on specialization, experience, and location—but on average, HVAC pays more and is growing faster.
Welding Salary Potential
The BLS reports a median annual wage of $53,750 for welders in May 2025. The lowest-paid 10% earned less than $39,240, and the highest-paid 10% earned more than $77,530. Specialty trade contractors pay welders a median of $59,440, compared with $56,080 in repair and maintenance and $51,210 in manufacturing.
Self-reported pay on Payscale averages $23.32 per hour, with entry-level welders averaging $18.91 per hour.
Specialized welders working in:
- Aerospace
- Industrial manufacturing
- Pipeline construction
- Underwater welding
may earn higher salaries than entry-level welders.

Self-reported pay on Payscale averages $24.50 per hour, with entry-level technicians averaging $18.61 per hour.
HVAC technicians can earn more, especially in:
- Commercial HVAC
- Industrial refrigeration
- Energy-efficient systems
- Specialized climate technologies
Experienced HVAC professionals may advance into:
- HVAC management

Work Environment Differences
One of the biggest differences between welding and HVAC careers is the daily work environment.
Welding Work Environment
Welders often:
- Work in industrial settings
- Spend long periods standing
- Work outdoors or in fabrication shops
- Handle heavy materials
- Work in high-heat environments
The BLS notes that welders face hazards such as fumes, very hot materials, and intense arc light, and may work on scaffolds high off the ground or in awkward positions. Many manufacturers run two or three 8- to 12-hour shifts, so evening and weekend work is common. The work can be physically demanding but rewarding for people who enjoy fabrication and building projects.
HVAC Work Environment
HVAC technicians often:
- Travel between job sites
- Work inside homes and commercial buildings
- Troubleshoot mechanical systems
- Interact directly with customers
- Handle both electrical and mechanical repairs
The BLS reports that HVAC technicians have one of the highest rates of injuries and illnesses of all occupations, with hazards including electrical burns and strains from lifting heavy equipment. Evening and weekend work, on-call shifts, and peak-season overtime are common. HVAC work may involve more customer interaction and diagnostic problem-solving.
Which Career Offers Better Job Stability?
Both careers have a similar number of openings each year—about 40,300 for welders and 40,600 for HVAC technicians, according to the BLS. The difference is growth: the BLS projects HVAC employment to grow 11% from 2025 to 2035, compared with 2% for welders. HVAC also benefits from year-round service demand because heating and cooling systems require regular maintenance.
Welding demand can vary more depending on:
- Construction cycles
- Manufacturing demand
- Infrastructure projects
- Industrial production needs
However, most welding openings come from replacing workers who retire or leave the field, and specialized welding fields can provide strong long-term opportunities.
Which Trade Career Is Right for You?
Choosing between welding and HVAC depends on your interests, strengths, and preferred work environment.
Welding May Be Right for You If You:
- Enjoy fabrication and building
- Prefer industrial work environments
- Like hands-on metalwork
- Want opportunities in manufacturing or construction
- Enjoy precision technical work
HVAC May Be Right for You If You:
- Enjoy troubleshooting systems
- Prefer varied job sites
- Like working with technology and mechanics
- Want customer interaction
- Are interested in climate and energy systems
Welding vs HVAC Outlook
Both trades offer a path to a stable income without a four-year degree, but the numbers favor HVAC on pay and growth. Here’s what the data shows:
- HVAC pays more at the median. HVAC technicians earn a median of $61,010 a year, compared with $53,750 for welders, and the top 10% of HVAC technicians earn more than $95,210.
- HVAC is growing faster. The BLS projects 11% growth for HVAC technicians from 2025 to 2035, versus 2% for welders.
- Openings are similar. Each trade has roughly 40,000 openings a year—about 40,300 for welders and 40,600 for HVAC technicians.
- Welding has a lower formal entry bar. The BLS lists a high school diploma for welders, while HVAC typically requires a postsecondary nondegree award plus long-term on-the-job training.
- Credentials differ. Nearly all HVAC technicians need EPA Section 608 certification, while welders often need AWS or employer-specific certification.
- Training is affordable at community colleges. Public two-year colleges average about $4,200 a year in tuition and fees, versus about $17,000 at for-profit two-year schools.
Choose the trade whose daily work fits you best—fabrication and metalwork or troubleshooting and customer service—and either can lead to a long, well-paid career.
