What is an outdoor HVAC unit and how does it work?

An outdoor HVAC unit is a crucial part of your heating, ventilation, and air conditioning system, typically located outside the house. It’s the outdoor counterpart to your indoor unit, working together to control your home’s temperature. The outdoor unit houses components like the compressor, condenser coil, and fan. Its primary role is to release heat absorbed from inside your home, a bit like how a fridge expels heat from its back. When your thermostat signals for cooling, the outdoor unit compresses refrigerant, turns it into a high-pressure gas, and sends it to the indoor unit, where the magic of cooling your home happens.
