Split systems are the most prevalent kind of HVAC system in the United States. There are indoor and outdoor components to it. The compressor and condenser coil are located in the outdoor unit, while the evaporator coil and blower are housed in the indoor unit. With the help of a central air conditioner, a furnace, or a heat pump, this system can provide both heating and cooling. Split systems are widely used in residential and commercial buildings due to their efficiency and effectiveness in maintaining indoor comfort.
