Manufacturer Contact Information 1-800-526-5265 Review: Powerful HVAC Maintenance Solution That Actually Works! - Frost King ACF19 Foam Coil Cleaner has been absolutely essential for maintaining our air conditioning system efficiency and has restored cooling performance that was noticeably declining due to dirty coils! As a homeowner who prefers DIY maintenance when possible but needs products that deliver professional-level results, this foam cleaner provides exactly the cleaning power needed to keep HVAC systems running optimally. The foam application system is incredibly effective at penetrating and lifting the stubborn dirt, debris, and buildup that accumulates on evaporator and condenser coils over time. Unlike liquid cleaners that run off quickly, this foam clings to surfaces long enough to break down contaminants thoroughly, ensuring complete cleaning rather than surface-level results. What impressed me most is the dramatic improvement in cooling efficiency after using this cleaner on coils that had become visibly dirty despite regular filter changes. The air conditioning system now cools faster, runs shorter cycles, and maintains consistent temperatures throughout the house, proving that proper coil maintenance directly impacts system performance. The 19-ounce size provides excellent coverage for complete residential HVAC system cleaning with enough product remaining for future maintenance cycles. The quantity is perfectly proportioned for homeowner use - sufficient for thorough cleaning without waste while being cost-effective compared to professional service calls. The ease of application makes this accessible for DIY maintenance without requiring professional equipment or extensive technical knowledge. The foam sprays evenly and consistently, making it simple to achieve complete coil coverage without missing areas that could compromise cleaning effectiveness. The cleaning action is powerful yet safe for coil materials, effectively removing buildup without causing corrosion or damage to delicate aluminum fins or copper tubing. The formulation appears specifically designed for HVAC applications rather than being a generic degreaser that might harm sensitive components. The rinse characteristics work perfectly with standard garden hose pressure, washing away completely without leaving residue that could attract new dirt or interfere with heat transfer efficiency. The clean rinse eliminates concerns about cleaner buildup affecting system performance or air quality. The odor control benefits have been noticeable in eliminating musty or stale smells that can develop when dirty coils harbor bacteria or mold growth. The fresh, clean scent after treatment indicates thorough cleaning that addresses both performance and air quality concerns. The preventive maintenance value is substantial for extending HVAC system life and maintaining energy efficiency that reduces utility costs. Regular coil cleaning with this product helps prevent expensive system repairs and maintains peak performance that justifies the minimal investment in maintenance supplies. The professional results at DIY pricing make this an outstanding value compared to service calls or professional cleaning costs. The effectiveness rivals what HVAC technicians achieve while being accessible for regular homeowner maintenance schedules. For homeowners committed to proper HVAC maintenance who want professional-quality cleaning results without service call expenses, this foam coil cleaner delivers exactly the cleaning power and ease of use needed to maintain system efficiency and extend equipment life through proper preventive care. Review: Great product highly recommended! - I purchased this after paying an air-conditioning company $100 to clean my AC unit. In my opinion I was able to do a professional quality job with this product. It is a great value. It’s easy to use and the foam fills the fins effectively and does a great job of pushing their debris out. Also, this product is rinse free! Which was nice because I didn’t have to drag a hose onto the roof and spray it into my air conditioning unit. I am not an AC technician this product was extremely easy to use for your average. I highly recommend this product. I plan on using it on my unit every spring. The effectiveness of my unit doubled after the cleaning!! I have included a before and after photo ## Features - Heavy-duty foam dissolves stains, removes grease & oil, and loosens dirt - Cleans coils, fan blades, and reusable air filters - Neutralizes odors from standing water in drain pans - Air conditioner coil foaming heavy duty detergent cleaner with low VOC formula - Pleasant lemon fragrance leaves deodorized, fresh smell after cleaning.

It had a build up of dust and grime. The foaming spray has a clean, pleasant smell and was mostly effective at loosening the dirt on the vent. I did need to scrub with a stiff bristle brush to remove the stubborn stains. Used a spray bottle with clean water to rinse the cleaner off after laying a towel down to catch drips. I would recommend this product. ## Frequently Bought Together - Frost King ACF19 Foam Coil Cleaner, 1.18 Pound (Pack of 1), 19 Ounce - Nu-Calgon 417175 Evap Foam - Boao Air Conditioner Condenser Fin Comb, Fin Cleaning Brush Air Conditioner Coil Cleaner Refrigerator Coil Cleaning Whisk Brush Evaporator Radiator Repair Tool(2 Pieces) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/6661261-frost-king-acf19-foam-coil-cleaner-1-18-pound-pack](https://www.desertcart.co.za/products/6661261-frost-king-acf19-foam-coil-cleaner-1-18-pound-pack) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-23*
