Tyrell Washington

HVAC Service Technician

Charlotte, NC · t.washington@email.com · (555) 671-2039

Dear Hiring Manager,

I'm applying for the HVAC Service Technician role at your company. I'm EPA 608 Universal and NATE certified with five years of residential and light-commercial experience, currently completing 6-7 service calls per day with a callback rate under 3%.

At Piedmont Heating & Cooling, I diagnosed and repaired split systems, heat pumps, and ductless minisplits from Carrier, Trane, and Goodman, and led over 300 seasonal tune-ups last year alone. I handle refrigerant recovery and charging to EPA standards and have replaced ductwork on aging homes to correct airflow and efficiency issues, improving customer SEER ratings by an average of 2 points.

I also generated $85,000 in maintenance-plan and system-replacement upsells last year by explaining efficiency trade-offs clearly to homeowners. I'm comfortable with summer on-call rotations and would be glad to bring that combination of technical skill and customer trust to your team — happy to discuss availability whenever works for you.

Sincerely,

Tyrell Washington
