HVAC - Easy Leak Fix

Sometimes, finding and fixing a refrigerant leak is like shooting fish in a barrel. This one wasn't difficult at all, so I added the tedium that goes along with it. The LCD display for my refrigerant scale was washed out by the sun, even though I was working under my umbrella. I'll have to work on my camcorder's issues with sunlight in the future.

After adding the entire system charge to both sides, how long to wait before turning the system on?

[PutSome5tankOnIt]

@ontariohvac I usually have a few things to gather up and put away. I use that time to power up the unit and let it sit for about 10-15 minutes. I don't have a set amount of time that I wait.

Thanks for the video. I know there are many opinions about pin hole repair, so I wanted to ask a pro. Is it ok to use Stay Bright solder, which has a much lower melting point, or 5% silver Harris to repair a pin hole leak in a evaporator? The reason I ask, is that I am concerned about using so much heat on the thin walled tubing of a evap. Heat weakens copper, and I think in R22 systems the pressure is low enough for StayBright. I repair rather than replace when possible/practical.

@douglas787 StayBrite would probably work. I prefer brazing alloy and a 'cold' flame on the oxy-acetylene. It takes practice but the sil-phos isn't as likely to flow into (and fill) the tubing. Heat the pinhole and dab a bit of alloy over it. Use the small (almost a pinpoint) flame to barely melt it into the hole. Then, feather/spread the melting alloy around the perimeter of the repair area. The higher the silver content (15% is fantastic stuff!), the easier it is. Thanks for watching.

@MegaBull8 Don't be stupid,he was using nitrogen to pressure test, why would it blow up?

[DVinoskey]

I have a pinhole leak on the center stub on the reversing valve on my heat pump. Would you just braze it to fix it or replace the reversing valve just because?

[gwozhog]

Excellent video. You should try liquid snoop. It is alot more expensive than what you are using but it will show micro bubles which the product you are using is not capable of doing.

[MegaBull8]

Yes!But you did not evacuate the system before you put the fire to it. You are lucky the place did not blow up.

easy money

@theonemam If Goodman is junk, why are they the only manufacturer that offers a 10 year warranty on just the condenser. Can't find that with Lennox, Carrier or Trane without buying a new evaporator too. I love em! I don't like the new Amana design though.

[mrsokla]

Your shraeder was leaking because they didn't remove them while brazing. Probably didn't wrap the valves with a wet wash cloth either. Probably didn't run Nitrogen when brazing either. Losers they are.

Also sounded like he spit in the area he was in...gross

[hvacdude32]

@hokanut there's a charge in the bulb and you want the tit of that bulb up not down to boil off when its reading the line temperature...no nitrogen to prevent flaking or carbon(soot) hit doesn't know hvac well
