Another option is to get some experience with a local company first and later start taking on smaller HVAC jobs independently. A lot of technicians eventually build their own client base through maintenance calls, basic repairs, and referrals. When working for yourself, it also helps to have a simple way to send invoices and collect payments. An app like https://tofu.com/ can be used for that, so you do not have to manage every payment and job record manually. Starting your own business is not the easiest route for a new graduate, but it could become a realistic long-term goal after gaining enough field experience and understanding the local licensing requirements.
