What is the typical voltage for compressors in residential HVAC systems?

• A. 120V
• B. 240V
• C. 480V
• D. 300V

Answer: (B)

The typical voltage for compressors in residential HVAC systems is indeed 240V. This voltage level is commonly used because it provides an efficient and effective power supply for the larger motors found in air conditioning compressors. Residential HVAC systems require enough power to start and run the compressor, and 240V allows for a reduction in current draw compared to a lower voltage supply, which can lead to smaller, more economical wire sizes and less energy loss due to resistance in the wiring. This helps ensure that the system operates efficiently and effectively within the confines of standard residential electrical systems. In contrast, voltages such as 120V are often used for smaller appliances and household circuits, but they do not meet the power requirements of a compressor motor adequately. Higher voltages like 480V are generally reserved for industrial applications where larger systems are in use and not typically found in residential settings. A voltage like 300V is not standard for HVAC systems, making 240V the correct choice for residential compressors.
