HVAC Electrical
There is a variety of high voltage and low voltage controls and wiring contained within your AC and heating system. Over time, some of these components will rust, burnout, and break. When that happens, you need a company that can diagnose and repair these issues, not someone who will tell you that you need a new system. When you need honest and expert advise for your complex AC and heating system, give the pros at Atlas HVAC of Brunswick, GA a call at

High Voltage and Low
Voltage HVAC Systems
Atlas HVAC of Brunswick, GA, specializes in professional heating, ventilation, and air conditioning services. Our certified HVAC technicians are experts in safely managing both high voltage and low voltage electrical systems as they relate directly to your HVAC equipment. We navigate the complex interplay of power and control systems within your furnace, air conditioner, and heat pump to accurately diagnose and repair electrical issues specific to these appliances.
Understanding Electrical Components in Your HVAC System
Every modern HVAC system operates using two distinct voltage types to function correctly.
High Voltage (Line Voltage) HVAC Components
The high voltage side of your HVAC system is responsible for delivering the main power necessary to run the heavy machinery—primarily the large AC compressor motor, the furnace blower motor, and the outdoor condenser fan. This is the main power supply (typically 120V or 240V) that enables the system to produce actual heating or cooling.
Our technicians safely diagnose and service high-voltage components within the HVAC unit itself, such as:
Dedicated Fuses within the equipment
Disconnect Boxes (outdoor switches)
High Voltage Wiring connections to motors and compressors
Capacitors and Relays that start motors and manage power flow
Low Voltage (Control Voltage) HVAC Components
The low voltage side (typically 24V) serves as the control circuit. This system manages the communication and safety controls within the unit, telling various components when to turn on or off.
Our team are experts at troubleshooting low-voltage issues involving:
Thermostat Wiring: The crucial communication lines running from your thermostat to the main unit.
Control Boards: The central nervous system of your furnace or air handler.
Safety Switches & Sensors: Components that shut down the system if a problem is detected (e.g., overflow switches, pressure switches, flame sensors).
Zone Control Systems: Managing comfort in different areas of your property.

Understanding the difference between high and low voltage is essential for safe and accurate HVAC repair. Atlas HVAC technicians are trained and equipped to identify if a problem is a control issue (low voltage) or a power supply issue (high voltage) and address it within the scope of our HVAC expertise.
