About Us

John Stevenson Plumbing, Heating & Air has served San Diego homeowners with honest, high-quality comfort solutions for decades. Our reputation is built on doing the job right the first time, communicating clearly, and treating every home like it’s our own. We’re growing and looking for an HVAC Service Technician who takes pride in being meticulous, customer-focused, and eager to keep sharpening their craft.

The Role

As an HVAC Service Technician, you’ll diagnose, service, and repair residential HVAC systems across San Diego County. This role is ideal for a tech who is solid on HVAC fundamentals, strong in airflow and system performance troubleshooting, and who believes in giving customers a complete, confidence-building service experience—not a quick patch.

What You’ll Do

• Perform thorough diagnostics on residential heating, cooling, and ventilation systems.

• Identify root causes (not just symptoms) and explain findings clearly to homeowners.

• Troubleshoot and correct airflow issues, including:

  • static pressure testing

  • duct and register performance checks

  • blower and fan diagnostics

  • filtration, return/supply balance, and comfort distribution problems

• Complete repairs to manufacturer specs and best practices, with clean workmanship.

• Provide comprehensive system evaluations and offer honest recommendations.

• Document work thoroughly in service notes, including readings, observations, and next steps.

• Maintain a high standard of customer communication, cleanliness, and respect in the home.

• Participate in ongoing training—company-provided—to expand beyond core HVAC basics.

• Follow safety procedures and uphold company quality standards every call.

What We’re Looking For

Required (Fundamentals):

• Working knowledge of HVAC basics: refrigeration cycle, electrical fundamentals, components, and common system types.

• 1+ year of residential HVAC service/maintenance experience or equivalent hands-on technical background.

• Strong mechanical aptitude and willingness to learn advanced diagnostics.

• Valid California driver’s license and clean driving record.

• Ability to lift 50+ lbs and work in attics, crawlspaces, rooftops, and tight spaces.

Highly Valued:

• Demonstrated experience diagnosing airflow and comfort issues.

• Comfort advising mindset: you like educating customers and solving whole-home problems.

• Attention to detail—your work is consistent, complete, and well-documented.

• EPA 608 Certification (or willingness to obtain quickly).

• Familiarity with San Diego housing styles and ducting challenges is a plus.

What Success Looks Like Here

• Customers feel informed and taken care of—because your approach is careful and complete.

• You test, verify, and confirm performance before leaving.

• You don’t just “fix it,” you explain the why and help prevent repeat issues.

• You grow your skills through training and become a trusted expert on airflow and system performance.

What We Offer

• Competitive hourly pay + performance incentives

• Medical, dental, and vision benefits

• Retirement plan options

• Paid time off and holidays

• Company vehicle, gas card, phone, and tablets

• Ongoing technical and customer-service training

• A supportive team with high standards and zero drama

• Real opportunity for advancement in a growing San Diego shop
