Beginner friendly: Moderate

Becoming an HVAC technician can be a moderately challenging side hustle for beginners. While no specific background is required, it does involve technical training and certification. Online resources like YouTube can provide some insights, but hands-on experience is crucial. With an average setup cost ranging from $1,000 to $5,000 for training and tools, it may require a significant initial investment. Typically, it can take around 6 months to 2 years to start earning a profit, depending on the individual's learning pace and job opportunities. I'd rate it a 3 because while achievable with time and effort, it does involve a learning curve and financial commitment.
