A system for providing efficient climate control in a vehicle. The system has an HVAC system configured to receive a user-defined temperature. The HVAC system has a cabin temperature sensor. The system has a controller coupled to the HVAC system and coupleable to a mobile device. The controller is programmed to (i) receive an estimated travel time of the vehicle from the mobile device and (ii) modify output of the HVAC system based on the travel time being below a time threshold.
