No experience but I did apply for apprenticeship in HVAC was wondering how would I go about getting into BAS?

While mapping out the full execution sequence of my conveyor digital twin—from motion and sensors all the way to decision logic and commands—I realized my execution order is completely uncoordinated.

​It’s super tempting right now to just throw together a giant manager script that controls everything and call it a day. But I’m holding off.

​Before writing more code, the real value is in understanding why the sequence is unstructured. My machine has plenty of behavior, but it still lacks a clear execution flow.

​For those who architect complex control loops or state machines: do you usually refactor immediately when you spot a structural flaw, or do you step back and map out the control flow on paper first?

​Hey everyone,

​I need some brutal, realistic feedback on my recent career move and long-term trajectory.

​My Background:

​Total YOE: 4 Years

​Domain: Building Management Systems (BMS), HVAC Automation, Field Protocols (BACnet, Modbus).

​Past Role (First 3.5 Years): HVAC Control Strategies

​Work: Creating complex control strategies and sequence logic for HVAC systems

​Pros: Deep domain knowledge, strong understanding of HVAC logic, sequence control, and global engineering standards.

​Cons: Core focus was strictly controls design/programming, with limited exposure to modern software engineering and automated testing pipelines.

​Current role: Hardware R&D QA

​Work: System-level validation and testing for embedded field hardware, thermostats, and wall modules.

​Pros: Top-tier R&D lab environment

​Cons: Heavy manual bench testing. Hardware peripherals like thermostats are currently tested manually, and there is no robust automated test framework in place yet.

​My Dilemma & Question to the Sub:

​Upgrade or Downgrade? On paper, moving from controls design to an R&D product lab felt like a step forward. But doing manual bench execution makes me feel like I’m losing software engineering velocity. Is this a lateral career trap?

Hey everyone!
I’m 31 and currently exploring a career change. I’ve spent a lot of time researching different career paths, trying to find something that aligns with my interests, existing skills, and long-term goals. Building Automation keeps coming up, and the more I learn about it, the more interested I become.
I have a pretty diverse work background, including automotive repair, electronics installation, troubleshooting, and technical customer support. I previously worked as an automotive technician and a Geek Squad Auto Tech, installing and troubleshooting electrical systems, aftermarket electronics, alarms, and other equipment. I also earned my MECP certification independently.
I’ve always enjoyed figuring out how things work, diagnosing problems, and working with technology. I’m comfortable with computers, electrical fundamentals, relays, inputs/outputs, and wiring diagrams. I particularly enjoy the combination of hands-on troubleshooting and computer-based work, which is part of what attracted me to BAS.
I’m currently working in hospitality, but I’m looking to transition into a more technical career with long-term stability, opportunities to grow, and a decent work-life balance. With a growing family, I’m trying to be thoughtful about the direction I take.
I’ve already applied to a few entry-level positions, but I’ve noticed that even some jobs advertised as entry-level seem to expect previous BAS experience or specialized qualifications.
So I figured I’d ask the people actually working in the industry:
How did you get your start in building automation?
Would someone with my background be a reasonable candidate for an entry-level position?
Are there any certifications, courses, or skills you’d recommend learning before getting hired?
What are the biggest challenges or downsides of working in this field?
Looking back, would you choose this career again?
I’m located in South Florida, if that makes any difference.
I’m not expecting to walk into a high-paying position immediately. I’m willing to start at the bottom, learn, and work my way up. I just want to make sure I’m investing my time in something worthwhile.
I’d really appreciate any advice or insight. Thanks in advance!

TL;DR: 31-year-old in South Florida looking to transition into Building Automation. I have a background in automotive repair, electronics installation, electrical troubleshooting, and technical support, but no direct BAS experience or college degree. I’ve applied to a few entry-level positions and am looking for advice on breaking into the industry, what skills or certifications to pursue, and whether BAS offers good long-term career growth, stability, and work-life balance. Would love to hear from people already in the field!
