An **HVAC app** is a software application—typically for smartphones, tablets, or computers—that allows users to monitor, control, manage, or service heating, ventilation, and air conditioning (HVAC) systems.
Depending on the purpose, an HVAC app may enable functions such as:
- Adjusting temperature and system settings remotely
- Monitoring energy usage and system performance
- Receiving maintenance alerts or diagnostic reports
- Controlling smart thermostats
- Assisting HVAC technicians with system configuration and troubleshooting
HVAC apps are commonly used by homeowners, facility managers, and HVAC professionals.
