HVAC professionals and DIY homeowners, this Foam Blaster coil cleaner is exactly what you need for keeping your air conditioning system running efficiently! This 3-pack kit includes both the powerful foam cleaner and special Flow Tabs that work together to clean and maintain your entire system. The foam cleaner uses a high-pressure spray that penetrates deep into coils then expands to liquify dirt, grime, and debris - it works on both evaporator coils (no rinsing required) and condenser coils (light rinsing needed). The citrus-scented formula leaves your system smelling fresh while removing odors. But the real game-changer is the Flow Tabs - these special gel tablets dissolve slowly over 3 months to keep your drain pan clean, clear, and odor-free, preventing clogs and overflow issues. Developed by actual HVAC technicians who use these products in their daily work, this professional-grade formula works on all HVAC units, refrigeration systems, automotive radiators, and more. Whether you're maintaining your home AC, cleaning mini-split units, or working on commercial systems, this foam blaster delivers professional results without the professional price tag. The expanding foam action ensures thorough cleaning of even the hardest-to-reach areas, helping restore your system's efficiency and potentially lowering your energy bills. Your AC will thank you for the spa treatment!
