Leak Saver AC Flush Solvent Kit | Pressurized AC Flush Kit Solvent for Cleaning HVAC Line Set and Any Refrigerant-Based Systems

A must have for flushing your HVAC system before assembling and once assembled to be safe.

I recently replaced a compressor and coil and changed refrigerants from R22 to R410. Rather than replace the lineset and do possible drywall damage, I elected to flush the existing lineset. I pulled both Schrader valve cores, put the rubber tip against one of the schraeder bodies and slowly opened the valve. The solvent in the can did an excellent job of flushing out the old oil and crud. I then followed it up with a dry nitrogen blast to remove any residue.This kit with the 1lb can is much easier than dealing with bulk solvent, measuring, possibly spilling or contaminating the flush. It's really the right way to go and makes invoicing the customer easier.

can't say much about a/c condenser flush except it did what it is supposed to do

Item is defective. As soon as I screwed the valve onto the canister with the valve closed, fluid leaked everywhere including hitting me in the face and burning. Amazon says I can't return it or get a refund. Nonsense.

This is convenient for flushing the lines on residential a/c units. You don't have to drag rhe nitrogen cylinder to the back of the house to flush a lineset. This thing is easy and convenient. The tapered rubber nozzle works well after you remove both Schrader valves. You just press it against the servicenport and press down on the lever and it doesn't leak.

This kit is intended to be the final flush for the system on which I am currently working. Everything is there that I will need to start that final flush.The question will be if I got the system pre-cleaned enough to make this the final step before assembling and recharging the new system.My AC system in a 1990 Ford Bronco was HEAVILY contaminated from years of a neglected grenaded AC system. The plan for this flush kit was to flush only the evaporator and replace everything else. The evaporator, too, was heavily contaminated and required scores of flushes recycling the fluid through a self help filtering system.I think it's only realistic to caution that if your system is contaminated at all to blow out the sections you want to clean with an inexpensive solvent first if you are trying to do this yourself. Personally, I wouldn't try to save any of the other components except the evaporator.I used non-chlorinated brake cleaner first, followed with a 1 gallon jug of AC cleaning fluid available from Autozone blown out with a compressor and re-filtered a number of times to remove all perceptible debris first. I have a little more to go before I want to use this kit.This is priced competitively with other similar kits I have considered. Four stars for the equipment, pending the final flush.

My AC started feeling tired. It still blew cool on the hottest days, but it wasn't cold anymore. I performed the flush and it worked. It not only sounds like it is operating better, but it is full on cold now.

Please note this is just the FLUSH kit, You will need to recharge you system after you are done with this process. It works very well and simple to use, I am a car guy but if you are not familiar with this process you might want to research it before buying. Did a good job and once the system was recharged it worked very well.
