Heat Ac Split Unit

A heat ac split unit is a type of air conditioning system that is composed of two separate units: an outdoor condenser and an indoor air handler. The condenser is responsible for the cooling process, while the air handler is responsible for the heating process. The two units are connected by refrigerant lines, which allow the refrigerant to flow between the two units. This type of system is typically used in residential and commercial buildings, and is an efficient way to both heat and cool a space. The condenser works by compressing the refrigerant, which causes it to become hot. The hot refrigerant is then sent to the air handler, where it is used to heat the air in the space. The air handler then sends the cooled air back to the condenser, where the refrigerant is cooled and sent back to the air handler to repeat the cycle. This cycle continues until the desired temperature is reached.
