    Have any of you used this "Cliplight" sealant on heat pumps? I'm considering putting it in a unit that I have been unable to locate the leak. I have some serious reservations about using this stuff but I've tried fluorescent dye and pressure testing with nitrogen on this particular system without any success.

    If you cant find the leak then it must be very very very very small.....I wouldnt put anything in that system thats designed to clog up an orifice....

    How much does it leak.... Have you tried isolating parts of the system and checking.... remove the evap coil and hose it down real good with soap... Ive pulled condenser coils before and evapoators and put them in a bathtub full of water before to find leaks.... seal off both ends of the tubing and check the line set at increased pressure...

    A good leak detector should find it....

    I wouldnt use dye either...but thats just me.

    Thanks for the ideas. I did a search on this site and found some negative comments about sealers, so I am NOT going to put that stuff in there. My main problem is that I'm the only service tech for our company which does over a million dollars a year in business, I average 7-8 calls a day and am not able to spend a lot of time on one call ( I know, my employer needs to hire more help......he has and they either don't know anything or they don't want to work overtime/nights/ weekends. Everytime we hire one, they last from 6 weeks to 9 months on average).

    I used the sealant in two old systems with success this summer. I will use it again in old systems to get some more life out of it.

    Could you elaborate a bit more about that...it's news to me, I thought it would need some air to react and I don't know how it would have anything to do with the orifice.

    great stuff. used it for a couple of years no problems,however some of the problems stated more than likley occured w/improper install of sealent you must pay close attention to the directions. install differs from r-22vs410-a.amazing had a leak on 90 fitt at line termination in wall(could see refer bubbling out) options were leakseal or cut out wall to repair leak(inside finished).installed leakseal.returned year later for tune up leak sealed refrigerant charge fine.

    I have a customer who has an early '99 vintage 2 Ton geo HP that started having to be recharged every 6 mos starting Jan 05. Another service person recharged it on 8/14. They added a can of "Leak Stop" (Cliplight Super Seal) with the recharge. During the night of 8/17 the system quit cooling. The service person returned on the 18th to check the no cooling. They said that the compressor would have to be replaced. I was called for a second opinion. The compressor was locked, just draw locked rotor. The system is out of the 5 year warranty, so now what does the customer do? Replace the evaporator coil (which is probably where the leak is) and the compressor? What about the Super Seal that's still in the HX and other piping? What affect will it have on the TXV and reversing valve? What kind of warranty can I provide on the replacement of the parts? Or does the customer buy a new HP? Also, the compressor had a SPP-6 soft hard start kit on it--previous problems with the compressor not wanting to start correctly? It's a Tech AW5519EXN with OEM piping.

    I have an idea. i have never believed in these type of fixes or used them, but maybee they have a place. we all go to the decrepit systems with condenrer on last leg & evap leaking & the cheap ass h.o. wanting us to juice it up a few times cause they refuse to replace the system.
    well why not put this crap in casue when it causes the compresser to **** the bed, they no longer can call you & try to get you to gas there piece of crap up, we will only gas & go once for a customer at there request. this could possibly end those fools calling to have refrigerant put in there piece of crap. lol

    Maybe. We've used the sealant in 6 systems since we have known about it. One was a leak in a lineset on a new system that we could not get back to because of the expense of tearing out the wall. I discussed the stuff with the customer and they okayed it. That was two years ago and it has ran fine since. Another was a leak in a almost new 50 ton coil. The customer was willing to try it rather than go to the trouble and expense of changing the coil again and it has ran all summer without a problem. The other four systems we put the stuff in were systems that were worn out and ready to be changed, but they were running except for the leak. All four of those have since died and been changed out, but I can't say if the sealant did them in, or just old age. All those times being low on freon didn't do them any good either. Just hard to say...
