On flight to hospital with patient on board; crew and I noticed that the air conditioning stopped operating and then there was a strong smell of something burning. After turning off the air conditioning unit; I performed an 'S' turn to check for a visible smoke trail. With no visible smoke showing; [I] performed a precautionary landing in a safe and accessible location so that the responding EMS service could access the patient and crew to continue to the hospital. After landing; we checked the aircraft to make sure it was safe for the crew and patient to remain in the area and then contacted Maintenance Dispatch to update the events as they were progressing. Assisted crew and patient loading into EMS unit on scene and waited for Maintenance.
Pilot on a patient transport flight noted a loss of the air conditioning system followed by a burning smell; so performed a precautionary landing and transfer of the patient to another EMS unit.
