Becoming an HVAC Technician can be a remote-friendly side hustle to a limited extent. While the technical aspects of the job can often be done remotely with the use of technology for diagnostics and troubleshooting, there are times when on-site visits to clients' locations are necessary. This means that you may not be able to truly work from anywhere at all times. Many professionals in the HVAC industry mention on forums such as Reddit that while there are remote aspects to the job, it still requires physical presence for certain tasks. The extent of remote work can also depend on your location, access to clients, time zones, and the equipment you have available. It's important to note that some hands-on work may be required, limiting the complete remote-friendliness of this side hustle.
