HVAC Diagnostic Tools — Accurate Testing for Faster Service

Equip every truck with HVAC diagnostic tools designed to speed up troubleshooting, improve accuracy, and reduce call-backs. This category brings together the essentials techs rely on daily—digital multimeters, clamp meters, manifold gauges, micron gauges, combustion analyzers, leak detectors, smart sensors and more—so you can run cleaner diagnostics on heat pumps, gas furnaces, mini splits, and refrigeration systems.

• Digital multimeters & clamp meters for electrical testing, amp draws, capacitor checks, and safety verification.
• Manifold gauge sets for refrigerant charging, performance checks, and refrigeration diagnostics.
• Micron gauges to confirm deep vacuum levels before charging—critical for heat pumps and mini splits.
• Electronic leak detectors for accurate refrigerant leak finding on R410A, R32, R22, and commercial blends.
• Combustion analyzers & flue gas tools for furnace tuning, combustion safety, draft testing, and CO monitoring.
• Smart probes & IAQ sensors for wireless temperature, pressure, humidity, CO2/VOC monitoring, and mobile reporting.

Reliable diagnostics save time and prevent unnecessary parts replacement. Use product filters and the Compare feature to match ranges, refrigerant compatibility, sensor type, wireless connectivity, and application-specific tools suited for residential or light-commercial work.

Pro tip: Build a dedicated diagnostics case with your primary meter, gauge set, leak detector, and micron gauge. Keeping all critical HVAC diagnostic tools in one organized kit prevents downtime, ensures consistent testing, and helps standardize procedures across your team or company.
