Job Description

Job Description

Step Into a Day on Our Service Team

Picture this: you start your morning reviewing the day's service calls, loading the van, and heading out to keep commercial and residential environments comfortable and safe. Your core mission is to install, maintain, and repair heating, ventilation, and air conditioning systems—especially complex chiller and boiler setups.

How You’ll Make an Impact

On site, you put your chiller expertise to work—because it’s required for this role. You diagnose issues using tools such as ohmmeters and other diagnostic instruments, perform preventive maintenance to maximize efficiency and safety, and clearly explain findings to clients. When equipment is down, you repair or replace components like compressors, pumps, and motors, and you’re ready to weld when a repair or installation calls for it. Between calls, you assist with property maintenance items related to HVAC and keep paperwork current from the field.

Your Toolkit

• Required: Hands-on chiller experience and proven background as an HVAC technician.
• Brand familiarity: Aaon systems preferred; knowledge of Laars and Aerco boiler operations is a plus.
• Technical range: Refrigeration systems, appliance/equipment repair techniques, and basic plumbing capabilities for installs/repairs.
• Field readiness: Valid driver’s license with a clean record to operate company vehicles and travel to job sites.
• Professional strengths: Clear communication, customer-first mindset, problem-solving, and attention to detail.
• Education: HVAC certification or related credential preferred (not required).

What a Typical Week Includes

• Installing, servicing, and repairing HVAC systems with an emphasis on chillers and boilers.
• Diagnosing faults using ohmmeters and advanced diagnostic tools.
• Completing routine maintenance to sustain system performance and safety compliance.
• Repairing/replacing compressors, pumps, and motors; welding when necessary.
