Final answer:
The indoor coil is usually mounted in the air stream before the auxiliary electric heat strips to efficiently heat the air passing through.
Step-by-step explanation:
The indoor coil is usually mounted in the air stream before the auxiliary electric heat strips.
When the air conditioner is running, the indoor coil serves as the evaporator, absorbing heat from the indoor air. The auxiliary electric heat strips are used as a backup heating source when additional heat is needed. To ensure efficient heating, the coil is positioned in the air stream before the electric heat strips, allowing the air to be heated as it passes through the coil before reaching the heat strips.
