Electrical

Shop professional-grade HVAC electrical tools and test instruments designed for safety and accuracy. From True RMS clamp meters and digital multimeters (VOM) to non-contact voltage testers and data loggers, our selection features top-rated equipment for diagnosing electrical faults, measuring power consumption, and verifying system safety.

What electrical tools does every HVAC technician need?

Electrical diagnostics make up a massive portion of HVAC service calls. A complete electrical toolkit should include:

Clamp Meter: The workhorse of the trade, used for measuring amp draw on motors and compressors (often with True RMS capabilities).
Digital Multimeter (VOM): For precise voltage, resistance, and continuity testing on control boards and sensors.
Non-Contact Voltage Tester (NCVT): A critical safety tool to quickly verify if a circuit is live before touching it.
Electrical Data Loggers: For tracking intermittent electrical issues over time.

Why are CAT ratings important for HVAC tools?

Safety is paramount when working with electricity. Categories (CAT) define the voltage and energy transients a tool can withstand. Most residential and commercial HVAC work requires tools rated CAT III 600V or higher to ensure technician safety during testing on distribution panels, motors, and outdoor units.

What is the difference between a Clamp Meter and a Multimeter?

While both measure voltage and resistance, a clamp meter features a jaw that clamps around a wire to measure current (Amps) safely without breaking the circuit. A multimeter (or VOM) typically relies on test leads and is often more precise for low-voltage controls, capacitance, and diagnosing circuit boards.
