hilmor HLC007 HVAC Lineset Cleaner - Pressurized Foam Puck System to Remove Contaminants & Residue - Refrigerant Line Set Cleaning Kit - A2L Compatible

I love this tool. It should be in ever technician’s toolbox. It is super easy to use. The time it saves is worth more than the price.

Quick and easy, I love it.

It takes lineset cleaning to another level, I had a compressor fail this past year after install. Blew cleaner through vacuumed and purged multiple times decided I was going to us this from here on out to prevent any doubts in my mind when switching refrigerants..

This is simply the best set up. I have used it several times and works much easier than I expected. The only thing it lacks is an 1 1/8 line capacity but I suspect the gun would need to be larger and that might not work for overall value.

Works great

My son the HVAC tech selected his as a means of cleaning and reusing residential linesets. He routinely deals with R22 units that have reached the end of their economical life and need to be replaced with newer R410/R407C units that have different refrigerants and incompatible oils. Replacing the lineset can be an arduous task, depending on how it is run and adds considerable time and customer expense to a job.The unit itself is basically a blowgun that pushes appropriately sized foam pigs through the lineset to wipe away old refrigerant, remains of oil, and contaminants. Thing of it as a "chimney sweep" of the lines. The selection of couplers fits most automotive and residential refrigerant lines and the foam pigs are disposable items. He tested it using both an air compressor and a nitrogen bottle and regulator. He preferred the nitrogen tank due to easier control of pressures and volumes by using both the valve and the trigger.The case is an excellent unit that keeps the parts protected and organized. The pigs, while washable, should be considered a consumable item and are about $1.50-$2.00 each depending upon size and supplier.This is a time and resource saver for both the HVAC tech and the customer and allows the tech to be sure the lines are clean and clear before adding new refrigerants and lubricants.This tool is a winner.

Versatile, simple to use, great peace of mind:This set is an excellent way to keep linesets clean and clear and keep the efficiency as high as possible without the need for more expensive repairs or cleanings. The "pigs" included in the set run through the lines and physically clean out all the debris and chemicals within the lines, which is a huge advantage over typical cleaners that rely on cleaning agents that don't always provide a comprehensive cleaning and can damage the units and affect the quality of the oils. This product is surprisingly simple to use, and the video included on the product page shows you exactly how to use it. This product is so simple and so intuitively effective, there's little question the cleaning is comprehensive. Cleaner lines are a huge factor in the efficiency of the units you're cleaning, so being able to clean the system in a few seconds without any chemicals or harmful agents provides such good peace of mind that the system is functioning at peak performance without risking damage to the unit.Overall, this is a great product and I would recommend.

If you're in the refrigeration business and need a line set cleaner then this is an awesome option with 5 different sizes. You simply connect the appropriate adapter to the line you are cleaning. Attach the catch bag on the opposite side. Insert the Pig which you will send down the line. Close the chamber and pull the trigger. Just as easy as that. This is a very high quality set. I'm very happy with this product.
