Why this flush
Replaced a compressor and skipped
the flush? That one's on the clock.
USA-manufactured solvent-based HVAC-R line cleaner. Acid and carbon left in the line set after a burnout will eat the new compressor's oil within 60–90 days — and most OEM warranties won't cover the failure. One quart, one pass, one clean system.
OEM warranty compliance
Copeland, Bristol, and most major compressor manufacturers require documented line-set flushing on burnout replacements. Skip the flush, void the warranty. Flash Flush invoice is part of the warranty paper trail — keep it with the service ticket. The flush itself is cheap insurance against a $1,500 compressor on your dime.
Removes acid, carbon, and sludge
Solvent-based formula (heptane + IPA) dissolves acid residue, oil sludge, carbon deposits, and moisture left in the line set after compressor failure. Push it through with dry nitrogen at 150 PSI, blow out, and the contamination that would kill your replacement compressor is gone. Safe on copper, brass, aluminum, and rubber line-set materials.
One quart, residential to light-commercial
10–15 tons of refrigeration per quart — enough for most residential and light-commercial HVAC systems in a single pass. Heavily contaminated systems may need a second pass. Universal refrigerant compatibility means one product on the truck handles every job — R-410A retrofits, R-22 burnouts, R-134a auto A/C, R-1234yf, R-290/R-600a hydrocarbons.
Full Product Description
HVAC flush solvent for post-burnout line-set cleaning, refrigerant retrofit prep, and major system service — the OEM-warranty-compliant flush that Copeland, Bristol, and most major compressor manufacturers require on burnout replacements. Skip the flush, void the warranty.
HCPRO Performance Flash Flush is a 32 oz (1 quart / 946 mL) solvent-based HVAC-R line cleaner. Active ingredients: heptane (CAS 142-82-5) and isopropyl alcohol (CAS 67-63-0). Coverage: 10–15 tons of refrigeration per quart. Specific gravity 0.68–0.72 g/mL, boiling point >100°F. Universal refrigerant compatibility: R-410A, R-32, R-22, R-134a, R-1234yf, R-404A, R-290 propane, R-600a isobutane, and R-12. Safe on copper, brass, aluminum, and rubber.
Who this flush is for
HVAC technicians replacing compressors on residential and light-commercial systems. Refrigeration contractors servicing walk-in coolers and freezers after compressor failure. Automotive A/C technicians flushing line sets after burnout. Anyone whose customer paid for a compressor replacement and expects the new one to last more than 90 days.
When to use it
After every compressor burnout (mandatory for OEM warranty compliance). During R-22 to R-410A or A2L refrigerant retrofits. After major system contamination from acid, carbon, or moisture. Push through line set with dry nitrogen at 150 PSI — NEVER compressed air or oxygen. One quart per 10–15 tons; double for severely contaminated systems. Allow 15–30 minutes evaporation before pulling vacuum, then evacuate to 500 microns and recharge.
Why this flush vs cheap alternatives
Industry-standard heptane + IPA chemistry — the same active ingredients used by major-brand HVAC flushes. Universal refrigerant compatibility (works on every system on the truck). Documented OEM warranty compliance (keep the invoice with the service record). USA-manufactured to industry HVAC flush standards.
Available in single 32 oz can and 6-pack at trade pricing. Flammable liquid, DOT Class 3 — ground shipping only within US 48 states. Manufactured in the USA to industry HVAC flush standards.

Common questions
Answers from the warehouse floor.
Still stuck? Call our techs at 305-720-0044.
Does HCPRO warranty the products?
Yes — every HCPRO product ships with a 1-year limited warranty against manufacturing defects. We'll replace the can if it fails to meet stated specs under normal use. See our full warranty terms.
Do I need to flush after every compressor burnout?
Yes — even a minor burnout leaves acid and carbon in the line set. Skipping the flush is the #1 cause of repeat compressor failure within 60–90 days. Most OEM compressor warranties (Copeland, Bristol, etc.) require documented line-set flushing on burnout replacements.
Can I reuse the line set after a burnout?
In most residential and light-commercial cases, yes — provided you flush thoroughly and pull a deep vacuum (500 microns or below). Replace the line set only when contamination is severe or the line set is undersized for the new system.
What pressure should I push the flush through at?
150 PSI of dry nitrogen is the industry-standard pressure for HVAC line-set flushing. Never use compressed shop air (introduces moisture) or oxygen (explosion hazard with hydrocarbons).
How long should I wait between flush and recharge?
After the final nitrogen blow-out, allow 15–30 minutes for solvent evaporation before pulling vacuum. Then pull to 500 microns and hold for at least 15 minutes to confirm no leaks before recharge.
Will skipping the flush void my compressor warranty?
Almost always, yes. Copeland, Bristol, and most major compressor manufacturers require documented line-set flushing on any burnout replacement. Keep your Flash Flush invoice — it's part of the warranty paper trail.
Will it work with R-410A, A2L, or hydrocarbon refrigerants?
Yes — all of them. Compatible with R-410A, R-32, R-22, R-134a, R-1234yf, R-404A, R-290 (propane), R-600a (isobutane), and R-12. Universal refrigerant compatibility is built into the solvent chemistry — one bottle handles every job.
Why is this ground-shipping only?
Flash Flush is a flammable liquid (heptane + isopropyl alcohol) classified as DOT Hazard Class 3. Federal regulations prohibit air freight of flammable liquids in standard consumer shipments. We ship via ground UPS/FedEx within the US 48 states only — no international, no Alaska/Hawaii.
Can I return an unused can?
Yes — free returns within 30 days for unopened cans in original packaging via ground shipping. Opened cans cannot be returned (hazmat resale restrictions). Read our full return policy.
Do you offer bulk pricing for shops?
Yes — we offer a 6-pack at trade pricing on this page. For larger volumes (cases, pallets), email hcproproductsusa@gmail.com with your business details and we'll send a custom bulk quote within 24 hours.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.
