Review: Worth the Money, no problems, good stuff! - I couple of different A/C business owners, I know, suggested this for small leaks on the house system. I just recently bought some more, since I needed to add freon to my system. The original same product has been in my system for 12+ years. I've never had any problems due to this product being in my A/C system. The A/C owner/personal friend of mine suggested using a paint gun to push the plunger in on this product and it certainly did make it a lot easier to get it in the system. Also I would recommend installing this product while the system is low on freon, before topping off the system. It should make it easier to get the product in the system. Review: Mission accomplished - It seals the crack, more time to evaluate needed though.

I just recently bought some more, since I needed to add freon to my system. The original same product has been in my system for 12+ years. I've never had any problems due to this product being in my A/C system.

Only two weeks since applied ### ⭐⭐⭐⭐⭐ Works great *by D***A on December 15, 2024* This works great if you're a professional and know how to use it. The syringe way is only if the system has zero ps or is in a vacuum. When trying to add when system has a charge I would fill my hoses and burp them. If you don't know what your doing as a homeowner you can screw your system up, non condensables are not your friend. ## Frequently Bought Together - Rectorseal 45312 AC Leak Freeze 1.5oz Cartridge, 1.5 oz - Rectorseal 45316 AC Freeze PRO Nano Leak Sealer, 1.5 oz, Blue --- ## 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.tn/products/28481755-rectorseal-ac-leak-freeze-45312-leak-sealant-easy-application-hvac](https://www.desertcart.tn/products/28481755-rectorseal-ac-leak-freeze-45312-leak-sealant-easy-application-hvac) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-17*
