Not quite right. When the refrigerant expands it cools. When it is compressed it heats.

All of this begs the question for the original poster, will the air which is dehumidifier by the central a.c. Dry enough to satisfy him/her.

With the current weather conditions a home with A.c. Set between 70 and 80 will have a relative humidity of 50 to 60. Most Americans find this completely acceptable particularly if it is close to 50. But I can understand someone from a desert region may want a dehumidifier over ac. Or in addition to ac.
