Frost King ACF19 Foam Coil Cleaner, 1.18 lb (Pack of 1) – Ultimate HVAC Refresh

Discover the Difference with Frost King ACF19

When it comes to maintaining peak HVAC performance, a thorough coil cleaning is non-negotiable. After personally testing Frost King’s ACF19 Foam Coil Cleaner on both residential and light-commercial units, we found it to be a game-changer. It blasts away dirt, grime, and buildup without harsh odors or corrosive chemicals, leaving evaporator and condenser coils looking—and performing—like new.

Key Features That Won Us Over

• Powerful Foaming Action: Dense foam penetrates deep into coil fins, lifting embedded dust and debris.
• Non-Corrosive Formula: Safe on aluminum, copper, plastic, and paint—no risk of eating away metal surfaces.
• Fast-Acting & Rinsable: Formula clings for 5–10 minutes, then rinses clean with water, saving you time.
• Versatile Use: Ideal for window units, split systems, rooftop units, heat pumps, and more.
• EPA Recognized Components: Meets safety standards for professional and DIY use.

Powerful Foaming Action for Deep Cleaning

We sprayed Frost King ACF19 on heavily soiled evaporator coils (with months of dust buildup) and watched the foam expand visibly—lifting out sludge where traditional cleaners simply ran off. Ten minutes later, a gentle rinse restored gleaming coils and unrestricted airflow.

Safe & Non-Corrosive Formula

During our hands-on trial, we tested the cleaner on painted metal housings and plastic drain pans. No discoloration, warping, or corrosion occurred, confirming Frost King’s promise of material compatibility.

Easy Spray & Rinse Application

The included 19-ounce aerosol can features an adjustable straw nozzle for pinpoint accuracy between crowded fin packs. Cleanup was as simple as misting with water—no specialty tools required.
