It’s designed for small businesses to streamline their review generation, referrals and social media content. The app is available for iOS and Google Play, and NiceJob offers a free demo.

4. FleetSharp

As with the other apps in this section, this isn’t a HVAC app, but it can benefit your field service business.

Monitor your fleet in real-time, track road safety and get insights into your fleet organization.

The benefits of this app are the ability to diagnose issues directly from a smartphone device or tablet, using the dashboard for different modes to reduce manual labor. In addition, access previous service data and notes from other contractors about the history of the device and system. This can save you time and effort.

The primary downside is the limitations of the available connections. This HVAC app is designed to connect only to Goodman and Amana brand units. Bluetooth can occasionally be unreliable, depending on the device and the unit itself.

Both a benefit and a downside is this isn’t a dedicated HVAC app: it’s a plus as it isn’t yet another app (especially as it has a specific use) but does require an internet connection as you have to use a browser on a desktop or mobile device.

This doesn’t mean they have nothing to offer businesses, but they are focused more on individual skills development than the needs of running a field service business.

18. HVAC School

Whether you’re just starting your journey in HVAC or need that extra reference in the field, HVAC School is an HVAC app for technicians, by technicians.
