NEXTRADE OEM PARTS — HVAC COIL CLEANERS & CHEMICALS Nu-Calgon 4171-75 Evap Foam No Rinse Aerosol Coil Cleaner — 18 oz Heavy-Duty Alkaline Foam · NSF-Registered for Food-Area Use · Available in 1, 2, 4, 6, 12-Pack HVAC TECHNICIANS & AC SERVICE PROS: Dirty evaporator coils don't just hurt efficiency — they cause callbacks. Fouled fins drop heat-transfer capacity 15–30%, raise discharge temperatures, and breed the smell that brings homeowners back to the phone. Nu-Calgon 4171-75 Evap Foam is the no-rinse foaming aerosol coil cleaner spec'd by HVAC pros across residential, light commercial, and food-area applications — the right tool when you need to leave a clean, neutral-pH coil behind in a tight return-air cabinet you can't get a hose to. WHY CHOOSE THIS NEXTRADE LISTING ✓ Authentic Nu-Calgon 4171-75 — genuine 18 fl oz aerosol can, sourced direct from authorized distribution. Not relabeled. ✓ No-rinse formula — the heavy foam liquefies dirt and grease, condensate carries the residue to the drain pan, no need for water flush. Ideal for indoor coils where rinsing isn't practical. ✓ 360-degree spray — sprays right-side up or upside-down. Reach the back side of the coil through the access panel without disassembling the air handler. ✓ NSF-registered for food-area use — cleared for HVAC service in and around food processing areas. Use it in restaurants, supermarkets, and food-grade facilities without a separate food-safe product. ✓ Pack size variations — select 1, 2, 4, 6, or 12-Pack from the dropdown. Bigger packs = lower per-bottle cost, free of charge. ✓ Same-day dispatch from Florida — orders placed by 2pm EST ship the same business day. Aerosols ship ground-only (LQ hazmat), USPS Ground Advantage with tracking. HOW TO USE 4171-75
Prep: Power off the unit. Cover any electrical components (capacitor, contactor, control board). Remove visible debris from the coil fins with a soft brush.
Apply: Shake well, hold the can 6–8 inches from the coil, spray a heavy foam coat onto the dirty surface. Let it dwell 5–10 minutes — the foam will turn brown as it lifts soil. Spray both faces of the coil where access permits.
Rinse / drain: No water rinse required — restart the unit and condensate during normal operation will carry the dissolved soil down the drain pan. For heavily soiled coils, a light rinse is acceptable.
Coverage: 1 can (18 oz) typically cleans one residential 2–3 ton evaporator coil. Light commercial / RTU coils may need 2 cans.
Safety: Contents under pressure — aerosol can. Use in well-ventilated area. Wear eye protection. Do not spray on hot surfaces or near open flame. Follow SDS for handling, storage, and disposal.
