HVACD Technical Applications Support

About DCA

Dehumidifier Corporation of America (DCA) designs and builds commercial/industrial dehumidification systems used in natatoriums, manufacturing, and other demanding environments. Founded in 1995 and headquartered in Cedarburg, WI, we’re investing in product quality, training, and support—while keeping the tight-knit, family feel our long-tenured team loves.

The Opportunity

If you’ve spent years diagnosing refrigeration circuits, reading schematics, and coaching younger techs—and you’re ready to trade the ladder for a headset—this role is for you. You’ll be the calm, trusted voice who helps contractors, reps, and service teams get DCA equipment running right. Most days are phone/Teams and documentation; a smaller portion is hands-on training and occasional site visits for start-ups or complex issues.

Who this role is great for

• A seasoned HVAC/R service technician ready to reduce physical demands and travel.


• A former service manager or small business owner who enjoys teaching and problem solving.


• A controls-savvy tech who loves turning hard-won field know-how into clear instructions.

What You’ll Do

• Customer Support (80–90%): Guide contractors through safe, accurate troubleshooting—airflow/static, superheat/subcooling, sensors and safeties, 120V/24V control circuits, 3-phase/VFD basics.


• Training (Classroom + Field, 10–20%): Lead small-group trainings (5–10 people) for start-up/commissioning, best practices, and common diagnostic workflows.


• Documentation & Continuous Improvement: Capture case notes, write clear service bulletins, help keep manuals/troubleshooting trees current, and close the loop with Engineering/Production on recurring issues.


• Parts & RMAs: Recommend parts, create concise quotes/RMAs (warranty & non-warranty), and document root causes.

What You Bring

Must-have

• 5+ years HVAC/R field service (commercial/industrial preferred).


• Confident with the refrigeration cycle and psychrometrics (sensible vs. latent).


• Comfortable reading wiring diagrams/P&IDs and using a meter to diagnose control circuits.


• Strong phone presence: patient, friendly, and able to coach a tech to resolution.


• Organized, documentation-minded, and team-oriented; basic computer skills (email, Teams, Excel/Word).

Nice-to-have

• Start-up/commissioning or factory tech support experience.


• Experience with dehumidification applications or pool/natatorium environments.


• Familiarity with 3-phase power, VFDs, safeties, sensors, and setpoint strategies.

• Tight-knit team, direct access to leadership, and a growing product line.
