What it does
How Condenser Coil shows up at home.
The condenser coil wraps around or sits inside the outdoor AC or heat pump unit. Hot refrigerant moves through the coil while the outdoor fan pulls air across it, allowing heat to leave the system. When the coil is packed with cottonwood, grass, dirt, or bent fins, the system has to work harder and may shut down or damage expensive parts.
