Projected growth · BLS 2024
Pool and spa technicians keep millions of residential and commercial aquatic facilities safe, clean, and functional. The work combines water chemistry, mechanical repair, plumbing, and electrical systems into a hands-on trade with strong seasonal peaks and year-round opportunities in warmer climates. The PHTA (Pool & Hot Tub Alliance) estimates that the US has over 10.7 million residential swimming pools[3]. Every one of those pools needs regular service — and that's before counting commercial pools, water parks, and the fast-growing hot tub market.

Day one
What does a pool and spa technician do?
Technicians perform weekly water testing and chemical balancing, clean filters and skimmer baskets, inspect and repair pumps, heaters, salt chlorine generators, and automation controllers. They also handle seasonal tasks like winterizing pools in cold climates, opening them in spring, detecting and repairing leaks, resurfacing pool interiors, and upgrading equipment. Hot tub and spa work adds jets, ozonators, and cover maintenance to the mix. The best technicians understand both the chemistry and the mechanical side — a pool that's chemically balanced but has a failing pump is just as problematic as a working pump with green water.
Skills
Skills and qualities you need
- Water chemistry — understanding pH, total alkalinity, calcium hardness, chlorine/bromine levels, and cyanuric acid
- Mechanical aptitude — troubleshooting pumps, motors, heaters, and plumbing
- Electrical knowledge — pool equipment involves 120V and 240V circuits, timers, and control panels
- Customer service — explaining technical issues to homeowners in plain language
- Route efficiency — most pool techs service 8–15 pools per day and need to stay on schedule
- Physical stamina — outdoor work in heat, carrying chemicals and equipment
Day in the life
A working day as a pool & spa technician
What the trade actually looks like hour by hour — not just the skill list.
10:00 AM
Pump motor failure
Customer's pump won't prime — diagnose a seized motor, replace with a variable-speed (saves them 60% on energy), reprime, set the schedule on the controller.
1:30 PM
Heater + heat pump
Service a gas heater (clean burner, check gas pressure) and a pool heat pump (defrost cycle test, refrigerant pressures). Heat-pump pool heating is the fastest-growing slice of the trade in Mediterranean Spain.
4:30 PM
Spring openings + winterizations
Schedule next week's spring openings (cover off, equipment startup, shock the water) or fall winterizations (blow out lines, antifreeze, cover on). These two seasonal pushes are 30% of annual revenue.

Growth
Career growth and specializations
- Equipment repair specialist — higher-margin work than weekly chemical service
- Leak detection — specialized skill using pressure testing, dye tests, and electronic listening equipment
- Pool renovation and resurfacing — plaster, pebble, and tile work pays well
- New pool construction — requires contractor licensing but offers the highest revenue per project
- Commercial aquatics — hotels, municipal pools, and water parks need dedicated technicians
- Route business ownership — a solo tech with 80–120 weekly accounts can gross $150,000–$250,000+/year
