HCPro Tools by Service Workflow

The right workflow saves a callback. This guide walks you through HCPro's recommended approach for the most common HVAC-R service jobs.

Compressor Burnout Recovery

A burned compressor leaves acid, carbon, and decomposed oil in the line set. Skipping the flush is the #1 cause of repeat compressor failure within 60–90 days. Most OEM warranties (Copeland, Bristol) require documented flushing.

Recommended workflow:

1. Recover refrigerant per EPA 608 protocol
2. Replace the compressor
3. Flush line set with HCPro Flash Flush + dry nitrogen at 150 PSI
4. Replace driers and filters
5. Pull a 500-micron vacuum with HCEC-6S + Quick-Y
6. Refill compressor oil with RPO-32 POE
7. Recharge refrigerant to OEM spec

The Burnout Recovery Kit: Flash Flush + RPO-32 POE + HCEC-6S + Quick-Y + ISO VG46 pump oil

R-22 to R-410A or R-32 Retrofit

Converting a mineral-oil R-22 system to POE-oil R-410A or R-32. Requires careful oil change, line-set flush, and pressure-rating verification.

Recommended workflow:

1. Recover R-22 refrigerant (must be reclaimed, never vented)
2. Drain mineral oil from the compressor
3. Flush line set with Flash Flush to remove residual mineral oil
4. Replace TXV or fixed orifice if rated only for R-22 pressure
5. Pull deep vacuum to 500 microns with HCEC-6S
6. Refill with RPO-32 POE Oil
7. Charge with R-410A or R-32 per equipment OEM spec

Routine Maintenance

Annual or semi-annual service visit. Pressure check, leak inspection, filter swap, coil clean.

Recommended HCPro kit:

• Quality manifold with low-loss anti-blowback fittings
• Valve Core Removal Tool for under-pressure service
• ISO VG46 Vacuum Pump Oil — keep fresh oil in your pump between jobs

New Install / Commissioning

New HVAC system installation. The pull-down is everything — moisture and non-condensables are the long-term killers.

Recommended workflow:

1. Pressure-test the line set with dry nitrogen at 150–300 PSI
2. Pull deep vacuum to 500 microns or below with HCEC-6S + Quick-Y
3. Hold vacuum for 15+ minutes — confirm no leaks
4. Verify oil charge (factory or per OEM spec)
5. Weigh in refrigerant charge
6. Check system pressures and superheat/subcooling per nameplate

Leak Repair

Found a leak — fix it without losing a full refrigerant charge. Valve core leaks are the most common single-point failure.

Recommended workflow:

1. Locate leak (UV dye + light or electronic leak detector)
2. If valve core: use the HCPro Valve Core Removal Tool to swap core under pressure — no refrigerant loss
3. If component leak: recover, repair, evacuate, recharge
4. Pressure-test the system after repair before recharge
