That's how my A/C works. The WiFi remote functionality is an add-in box, and connecting it through the manufacturer's cloud is opt-in, if you don't then it just works over your local WiFi.
Same for my front door lock. It's a normal Yale keypad lock with a slot for an IoT module. Zigbee and Z-Wave modules are available for local control as well as a HomeKit module and an August module.
