Working in a skilled trade already sets you on a path of hands-on problem-solving, strong job security, and good earning potential. But what if you could multiply those benefits? Dual trades, or adding a second specialty on top of your primary license, can offer more flexibility, higher wages, and a broader range of projects to tackle. Below is a look at why certain trade combinations can be a real game-changer, along with some additional skills you can develop to make even more money.
Plumbing & Pipe Fitting
Plumbers focus on water and sewer lines, faucets, fixtures, and everyday household plumbing. Pipe fitters typically work with large-diameter pipes in commercial or industrial settings—think chilled water, condenser lines, or high-pressure steam in big facilities.
• Shared Skill Set
Both trades require an understanding of fluid dynamics, layout, and reading blueprints. Switching between the two on a job is often seamless, especially in a large building project.
• Career Stability
Whether it’s residential or commercial, projects often need both skill sets at different phases. Employers value someone who can handle standard plumbing one week and help lay out large-diameter piping the next.
HVAC & Electrical
HVAC technicians already deal with a significant amount of wiring for thermostats, compressors, and air handlers. Electricians, in turn, understand the core principles of circuits and voltage.
• Overlapping Competencies
HVAC systems frequently run into electrical issues—some estimate that up to 85% of home AC problems are electrical in nature. Being licensed in both allows you to solve the majority of issues without calling in a second technician.
• Boosted Earning Power
You can charge for each specialty service you provide, from installing electrical panels to troubleshooting refrigerant-based systems.
Refrigeration & Electrical
Refrigeration focuses on specialized gases, line sets, and commercial-grade cooling systems. Electrical covers everything from wiring and circuit breakers to advanced electronics.
• Job Variety
Larger refrigeration setups—like those in supermarkets or ice rinks—often need complex electrical hookups. If you’re trained in both, you can handle the entire installation or repair yourself.
• Travel and Specialty Work
Some commercial refrigeration projects involve high-end or niche systems. Electric skills let you handle advanced controls, while refrigeration knowledge keeps the system running smoothly.
Additional Skills to Increase Your Value
Plumbers:
- Leak Detection
Learning to use specialized acoustic equipment to locate hidden leaks under concrete slabs or in walls can set you apart. - Whole-House Water Filtration
Become the go-to expert on softeners, purifiers, and specialty systems. - Tiling or Basic Remodeling
When replacing shower pans or tubs, being able to finish the tile work in a bathroom remodel can capture a larger share of the job.
Pipe Fitters:
- Welding
Many pipe fitters already do this, but mastering advanced welding certifications (e.g., vertical or overhead) can increase your hourly rate. - Structural Skills
Understanding structural steel assembly or being able to read more comprehensive construction blueprints helps secure bigger industrial projects.
HVAC Technicians:
- Indoor Air Quality (IAQ)
Offering tests and solutions for better air quality—like purifiers or advanced filters—can boost your service sales. - System Controls
Many HVAC problems relate to faulty thermostats or control boards. Get specialized in diagnosing and repairing these electronic components.
Electricians:
- Solar Power
If you can install and hook up solar arrays, inverters, and battery storage systems, you’ll be at the forefront of a rapidly growing market. - Smart Home Systems
Lighting controls, security setups, and full home automation all rely on a solid electrical foundation.

Final Thoughts
Venturing into a second trade doesn’t just pad your resume; it can make you indispensable on the job site and keep you employed when others might be waiting for specific projects to start. Combining related trades—like plumbing with pipe fitting or HVAC with electrical—unlocks overtime opportunities, higher pay brackets, and can even pave the way for running your own multifaceted business. If you’re already a skilled tradesperson, consider where your current competencies overlap with another specialty and explore how you can invest in that next set of skills. The possibilities—and the paycheck—may surprise you.
