Supco has spent 75 years turning field headaches into affordable fixes for HVACR pros. The company still delivers the broad, value-driven aftermarket line contractors expect— like these three product families explaining why Supco parts ride on virtually every service truck today:
Electrical & Diagnostic Instruments
The handheld M501 megohmmeter checks compressor-winding insulation to 1,000 MΩ in seconds, letting techs certify motors on-site.
Pressure & Safety Controls
Factory-calibrated low-pressure switches such as the SLP2550 (opens 25 psi, closes 50 psi, 700 psi MOP) stop freeze-ups before they torch scrolls or trigger lock-outs.
Combustion & Furnace Parts
Drop-in pilot burner kits like the FLS0005 (three-lead SPDT, replaces Carrier LH680005) revive older furnaces without rewiring.
