Risk: Moderate

Starting as an HVAC technician from scratch can be risky if you can't afford to lose money. Beginners in this field could potentially lose money on tools, equipment, and training. Some may struggle to find clients initially, leading to a loss of time and energy. While there are startup costs ranging from $1,000 to $5,000 for tools and certification, success is not guaranteed. Online feedback suggests that some beginners have invested in training and tools but failed to generate enough income to cover expenses. I'd rate the risk a 2 out of 5 because there is a significant chance of losing money, especially if proper market research and financial planning are not done.
