Thank you Ty. Your videos always help. Last year I watched some of your videos when I was installing my Heat Pump using Manual J, S and D. The system has been running since and we are super happy with. Some family members got bills up to $500 on gas while we got just above $200. Definitely, a good system to keep your home with high standards of comfort. Thank you so much for your videos.

[@Scnermn2009]

Great video! I notice you mention when demonstrating the removal of the Schrader valve core that you get it on the first try. I use these religiously and I do upwards of 5-10 startups if not more per week. I have found that if you don’t over tighten the portion of the Schrader valve core removal tool where it connects to the Schrader valve port the valve core will come out every time. If you think about it when you over tighten at that particular spot you sandwich in the o-ring to the point it squishes into the path of the valve core which then rips it from the clamp portion of the stem. You can get it most every time if you don’t over tighten the connection on the Schrader valve port. Just an observation I made from using these thing’s religiously. It also help keep those o-rings in better shape for longer as it doesn’t tear them up as the threaded portion of the valve core scrapes by the o-ring on every removal. Food for thought…..

Used this setup to recover a 2-zone mini split unit that has leaked every year (3) since install. After about 10 months the head farthest from the compressor would start to ice up and leak inside, every year. Obviously didn't pull liquid because both service ports were on the vapor lines, so a 1/4" hose between the machine and the tank was fine, no chugging. I was sick of the terrible service from the company that had installed and charged me every time they came to try and fix their screw up. Going to install two single zone units myself to replace the 2-zone unit, likely with no leaks, and save thousands!

I wish more companies would invest in the proper tools for us to do our jobs quicker and better. These tools are expensive but an added 35 minutes or so of time saved adds up for the company over time. Unfortunately, companies have made technicians fearful of not completing jobs within their time frame, which forces techs to take shortcuts that they wouldn't otherwise take (like not pulling proper vacuums)

Hi Ty, When calculating refrigerant safe storage at 130° Do we divide the refrigerant density at 130° by the same water liquid density temperature at 130° to find the specific gravity of that refrigerant?

I have been using the HVAC school app for so long I will have to go look up the math way.

If I had a large quantity of refrigerant to recover I would look into your instructions. I deal with maximum 30 lbs. I use the regular gauge hoses and don't pull Schraders.

Do you remove the core depressor on the low loss fitting (with ball valve) connected to the vacuum pump for better flow?

[@jpechacek80]

Can you use the same Appion valve stem removal tool to remove and replace a valve stem on the high side under full pressure? (390 psi) I connected the tool and the gas pressure pushes real hard against the tool removal stem. I'm afraid the valve stem might get stuck in the ball valve.

[@OscarRodriguez-ik3vm]

What about a gauge to know the psi inside the unit ? Ik the recovery machine has them but wouldn't a more precise gauge helped ?

[@love2hvac]

You can always add a tee and a guage. Just avoid the small hoses and the manifold

[@Ashroyer86]

Also, the liquid will drop back in at the end you said but you'll still have some vapor in that hose right?

[@love2hvac]

Yes

[@r.s.1348]

Ty, what indicator tells you that all the refrigerant has been recovered? Is it necessary to have a vacuum gauge attached to your configuration?

[@love2hvac]

The EPA standards are pretty lax for recovery. In many cases Less than 200 pounds of refregerant they ask for 0 psig. In others its 10 or 15"hg. Overall that's a very small vacuum and most micron gauges would not even read at that point. There would be a good chance you would contaminate or damage a micron guage attaching it to a pressurized system. The deepest is for type 3 wanting 25mm absolute easily read with the a basic gauge. Great question

[@brandonle4930]

I would attach the compound gauge to the service port of the removal tool. Once you valve off, you can ready the pressure inside the system.

How necessary is the filter drier for reclaiming? I’ve only been in the industry for 5 years but never seen one being used this way.

[@illthinkofsomethinglater9095]

I have two questions. 1st: Why can't you just dump liquid refrigerant into the vapor port while the tank is upside down. Wouldn't the liquid just drop to the bottom anyways?? 2nd: when all of the liquid refrigerant has been recovered and you need to pull vapor from the system, do you then turn the tank rightside up again??? Or will the vapor just push its way through the liquid on the bottom of the tank? Thanks

[@Yourengineeringstandpt]

you need to inform the techs that are learning this let them know when too open the vapor side, is there a set time limit.

[@moonshinebandit6158]

what was the reason for not turning the recovery tank back over when changing to vapor recovery?

[@nathanstarbird5389]

It's because the recovery machine condenses the refrigerant into liquid when pulling out the vapor

How did you determine the vacuum for the recovery. I did not see any gauges. Or was this just demonstration purposes only.

[@love2hvac]

The recovery machine has a guage on it. EPA requires 0 psig for this appliance wich I exceeded.

[@kentuckyhillbilly455]

@@love2hvac I thought it was supposed to be 15 inches on your compound gauge. So I was thinking you would have put a wireless on the port for the core tool.

[@kentuckyhillbilly455]

@@love2hvac well I just learned something new. I thought and I thought I was told that after the what ever year and date your machine was to be able to pull down to a certain inch level. So I took that as that is where I was to pull my recovery to all the time. I do know that I. Vacuums when recovering I have reclaimed almost a pound or more depending on the size system. I generally don’t work on anything over 25 lbs. I get the rare occasional flooded evaporator system that has an ungodly amount of refrigeration for the size machine. While running a reclaim on a system that had 4lbs of 404a I had it in a vacuum and you could watch the compressor sight glass bubble. I would tap the can with a mallet to help release the refrigerant. I would also wrap a tank heater around the can to help it expand the refrigerant. I could eventually see the bubbles stop in the oil and then the weight on the reclaim tank would stall too. But I guess I have just been an over achiever all these years.

[@love2hvac]

Your doing it the better way for sure. It's best to go lower, you don't want the refregerants flashing out of the oil while your brazing. I like to energize the crank case heater or use a tank heater on the compressor to speed it up. I talk about that in one of these videos. EPA requirements are : For type 1 under 5lbs Using a recovery device manufactured before November 15, 1993  Compressor running or not, 80% of charge or 4 Inches Hg vacuum  Compressor running 90% or 4 Inches Hg vacuum On or after November 15, 1993  Remove 80% if the appliance is not running and 90% if running or 4 inches Hg For type 2 and 3 the requirements are: Very high pressure 0psig regardless of the recovery machine manufacture date (410A) High pressure less than 200 pounds of refregerant 0 psig regardless of the recovery machine manufacture date (R22) High pressure containing MORE than 200 pounds of refregerant 4" HG vacuum pump manufactured before Nov 15 1992 and 10" HG manufactured after. Medium pressure containing LESS than 200 pounds of refregerant 4" HG vacuum pump manufactured before Nov 15 1992 and 10" HG Medium pressure containing More than 200 pounds of refregerant 4" HG vacuum, pump manufactured before Nov 15 1992 and 15" HG after All Low pressure 25" HG vacuum, pump manufactured before Nov 15 1992 and 25 MM ABSOLUTE after

[@kentuckyhillbilly455]

@@love2hvac thanks for the info. I have been pulling it down to 15hg on the compound gauge for around 20 years now. That is what I thought I was supposed to do. That is what I understood my instructor’s saying some time ago. And agin I always noticed a difference and how much refrigerant came out of the system when it got that low. Just making sure it is recovered. I have had one or two systems I was pretty sure I pulled it all out and while working the torch I got the green flame of death. It definitely burns your nose and lungs. Phosgene gas is no joke. It is similar to mustard gas used in the Great Wars. That will help get the point across to people about hoe dangerous it is.

[@isaiahsmith1933]

Ty, can you get in trouble with EPA for recovering into the vapor side? I had an instructor tell me that.

[@love2hvac]

No sir Either way it's going into the tank. The EPA wants you to not cut the lines and vent.

[@love2hvac]

You can search "Enforcement Actions under Title VI of the Clean Air Act" and you will see every action ever taken. While I absolutely believe in refrigerant recovery, being scared of the EPA is not one of them. They are more interested in importing people, or companies that have deep pockets. I don't remember seeing a single technician fined for even venting. I personally know people that have reported others for venting with evidence and nothing happened. Again I believe we should follow the rules and laws but there is nothing in there about the law using vapor vs liquid. If there was, there certainly would not be anybody enforcing it.

[@love2hvac]

When an instructor has a class full of people it's difficult to explore every possibility and every what if scenario. It's much easier to have one way and get everybody in line for that one method as it saves time. Using the EPA as a scare tactic helps enforce that. Others just do not know themselves. Maybe they were taught that one way with the EPA out to get them and they pass that down the same way they learned. Either way, when in Rome do as the Romans, when in your instructors class do as he or she commands. They may not be correct in one specific example but they still can have a lot of great information to share.

How come recovery machines don’t need oil but vacuum pumps do?

[@love2hvac]

A vacuum pump uses the oil to make the seal in the vein style pump mechanism. Recovery machines use a piston type pump and use the oil flowing with the refrigerant to oil the parts. In the old days our recovery machines did have oil we had to change. They were heavy and big.

Once you have recovered it , do you keep it under your bed. Here in Africa we just let it out. Whats the point of keeping it.

Thousand ways to skin a cat, but those in not how I would speed up the process.

[@love2hvac]

The appion guages bust because of pulsing from undersized hoses. I have never had one leak. As for the core removal tools, use nylog, don't over tighten and they can be rebuilt with a non Appion kit for just a few $. I don't remember the part number off the top of my head. All of the brands last about a year. The next video fastest recovery includes the heat exchanger. There areany ways of doing recovery Wich is why I included several videos with several methods.

@@hvacdr The valve core is a restriction. Removing the restriction allows refrigerant to flow faster. It takes a few seconds to remove the valve cores but the time savings are substantial in recovery time. It actually takes less time to remove the valve cores than it does to grab a bucket and dill it up. OVertime people become set in their ways and are scared of trying new methods or learning new things. There is no reason to be afraid of this method. It's quite simple and after the first few tires you too will be able to quickly remove the valve cores and save recovery time. Imagine if you did this method and started the recovery while you were filling the bucket with water. You would have the best on both worlds.
