Lightly coat the hot dogs with oil spray. Place the hot dogs in the air fryer basket.
Air Fry at 380°F for 8-10 minutes depending on your preferred texture and size of hot dogs. If you like your hot dogs extra crispy, air fry at 400°F for about 6-8 minutes. Flip the hot dogs half way through cooking.
Heat the chili while the hot dogs cook.
Place hot dogs in buns then add chili and cheese on top. Cook in the air fryer for about one minute to warm and crisp the bread, cheese and chili.
