Air　source　heat　pump　(ASHP)　is　increasing　widely　used　for　residential　heating.　The　purpose　of　the　present　work　is　investigating　on　application　status　of　a　village　ASHP　heating　project　in　Beijing,　testing　and　analyzing　on　operation　status,　coefficient　of　performance　(COP),　energy　consumption,　and　energy　saving　rate　of　a　typical　ASHP　heating　system　during　two　heating　seasons　by　cumulative　quantity　of　heat　output　and　electric　consumption　every　day　or　hour.　The　results　show　that　ASHP　heating　system　has　a　steady　performance　and　maintains　no　less　than　2.32　running　COP　at　-2.04　degrees　C　outdoor　ambient　average　temperature　and　18.2　degrees　C　indoor　average　temperature　of　two　heating　seasons　and　up　to　56.9%　the　energy　saving　rate　comparing　with　the　electric　heating　system.
