A split heat AC unit is a type of air conditioning system that is designed to provide both heating and cooling capabilities. It is composed of two separate units: an outdoor condenser and an indoor air handler. The outdoor condenser is responsible for transferring heat from the outside air to the inside of the home, while the indoor air handler is responsible for circulating the air inside the home. The two units are connected by refrigerant lines, which allow the transfer of heat from one unit to the other. The split heat AC unit is an efficient and cost-effective way to keep your home comfortable all year round. It is also an energy-efficient choice, as it only uses the energy necessary to heat or cool the home. Additionally, it is a great option for those who want to reduce their carbon footprint, as it does not require the use of fossil fuels.
