The NATE Air-to-Air Heat Pump Installation specialty is a North American Technician Excellence credential validating proper installation of air-to-air heat pump systems of 30 tons or less. Candidates first pass the NATE Core (Installation) exam, then sit the specialty exam of roughly 50 multiple-choice questions, requiring 70% to pass within about a two-hour window via approved testing centers or live online proctoring. The exam is built from NATE's Knowledge Areas of Technician Expertise (KATEs) and covers heat pump system design and sizing, installation and line-set practices, wiring and thermostats, charging and metering, the reversing valve and defrost cycle, and commissioning. NATE certifications are valid for two years and renewed with 16 continuing education hours. This free prep includes 100 research-based practice questions with explanations and an AI tutor.
