Condenser Coil Cleaning

All Products – Condenser Airflow

W**A, W**H, T**H, T**S, W*RV Wall Mount Units:

These units are called “blow through condenser airflow” units

because they draw cool outdoor air from the sides and blow the

warm condenser air exiting the coil through the front grille.

C**H Wall Mount Units:

These units are called “draw through condenser airflow” units

because they draw cool outdoor air in the front through the coil and

blow the exiting warm condenser air through the unit sides.

I-TEC and Q-TEC Units:

These units draw the cool outdoor air through the top section of the wall

louver and exhaust the warmer condenser air out of the lower section of

the louver. I-TEC units also draw a small amount of air through the outer

right and left side of the louver.
