Hvac Split Systems

A HVAC split system is a type of heating, ventilation, and air conditioning (HVAC) system that is composed of two distinct components: an outdoor unit and an indoor unit. The outdoor unit is responsible for transferring heat from the outside environment into the indoor unit, while the indoor unit is responsible for circulating the air throughout the home. This type of system is often used in residential homes and businesses due to its ability to provide efficient and cost-effective heating and cooling. The outdoor unit contains a compressor, condenser, and evaporator coil, while the indoor unit contains a fan, filter, and air handler. The compressor is responsible for compressing the refrigerant and transferring it to the condenser, where it is cooled and then sent to the evaporator coil. The evaporator coil is responsible for absorbing the heat from the air, while the fan is responsible for circulating the air throughout the home. The filter is responsible for trapping dust and other airborne particles, while the air handler is responsible for controlling the temperature and humidity levels in the home.
