Split units AC and Heat are a type of air conditioning and heating system that are composed of two parts. The first part is an outdoor unit that houses the compressor, condenser, and expansion valve. The second part is an indoor unit that houses the evaporator and blower. The two parts are connected by refrigerant lines that allow the system to move heat from one place to another. Split units AC and Heat are ideal for areas where space is limited or where it is difficult to install a single unit. They are also energy efficient and cost effective, as they only require one compressor and one condenser to operate. Split units AC and Heat are also relatively quiet, making them a great choice for homes and businesses. Additionally, they are easy to maintain and repair, making them a great choice for anyone looking for an efficient and cost-effective air conditioning and heating system.
