5 days no video. I almost thought we lost you forever. Awesome stuff. Thank you

[stevenhartnett]

Thank you Mr. Ore. You keep me ahead of the game because everyone out here in Houston does not care about best practices.

It's something Ive done countless times, but I still enjoy these vids

You mentioned that you don't like to unsweat because of the oil and risk of fire. 2 things that happened to me (in my earlier days). Unsweating once in an attic holey crap was that a ball of fire lol (I can laugh now but scared the crap out of me). Second is something people should know (maybe should be in a video you would do Bryan, on fixing condenser coils). Found small leak in condenser coil. Emptied ref' from low side only (I know 🙈). Figured unit is empty. Started my torch to heat up the pipe so my rod would melt on the hole. Now that was not a ball of fire but such a boom that I felt it in my bones. The expansion from the heat caused the pipe to blow. Thank God I didn't get injured, was pretty close.

I am just a customer who likes to get educated. You videos definitely do the job. How many contractors would actually be this thorough. And how do you find a contractor as detailed oriented as described in your video?
Thanks for continuing with your excellent instructional videos.

The videos might not get much viewership but thank you for this. Its helping out so much.

Very informative! Not in the profession but gives me some basic info to understand the process and good practices. A lot is still over my head. Trying to work with a company that replaced the evaporator, now a leak somewhere two weeks later.

Great instructional. I would add a VERY, nay EXTREMELY important stage if exchanging a copper coil with an aluminum. Clean, nay, SCRUB the rear and forward interior surfaces (Any area the coils will touch).

You can go one step further and place a tape bearer between the existing interior and the new aluminum coil. If any copper residue finds its way onto the new aluminum coil it WILL cause it to leak.

Short, sweet, and to the point! Thank you.

I have an 8 year old York system. We lost cooling due to a leak over time. Had a company come in and diagnose it's the coil with 2 leaks. They topped off the refrigerant and gave us an estimate. I come to find that parts are covered to 10 years on YORK but, I have to use a YORK authorized repair person. So, I paid this first guy his $500 for the diagnosis and top off of the R410. He told me that the YORK authorized person I choose can just reuse the same R410 in my system. I had to choose a local York authorized repair company and they tell me that to replace my coil, they need to use all new refrigerant and charge per pound accordingly. Is this true? They already ordered and received my evap coil and want to schedule but, I feel like they are BS me. Great video!

Greatest teacher ever....Wish I could of attended your class..

BRYAN, , Hello, nice video, I once followed a fellow I met @a GRAINGERS, to a job, it was in PARKLAND, BROWARD COUNTY, FL as I got into that home, it smelled of SEWER GAS. he did not smell it, , he was there to just. ADD refrigerant, this was the 3rd evap, cause ? CHINESE DRYWALL, you should have seen how black the copper &copper electric wires too, That was something I will never forget !
Cheers 🇺🇸🇺🇸🇺🇸🇺🇸

Thanks. In case I need to call for repair, I have a much better idea of what to look for while observing the procedure.😊

Great videos! Where do you stand on pressurizing the evap with nitrogen when service valves are closed on a pumped down residential split system? Many older techs say that practice can push nitrogen into the condenser, and it should only be done if the lineset is cut away and fittings brazed in. Or, recover all refrigerant, and pressurize the entire system. I usually am not worried about new condensers, but with the number of times I have seen brazing near service valves without protection, it has me wondering where you are on the topic. Thanks for all of the great content!

I hope that this is not going to be trend by manufactures where you ordered a warranty evaporator coil and the new coil does not come with a drain pan.

[michaelstaley]

Another great video. Learned a lot from this one from start to finish.

Great video again! Question for an expert: in a one way air to water heat pump with a TXV, do you need any check valves? I ask because when switching off the system hot refrigerant flows back into the evaporator coil instantly and don’t want to cause premature damage. Any thoughts is much appreciated

[jameskennett]

Amazing videos 👏🏼 always help understand concepts with the great visuals you include with the detailed explanation

[kulpreet]

after you do a pressure test with nitrogen, do you just open the valve to relieve the nitrogen or do you use the evacuation process to remove all the nitrogen?

[tjslbfyt]

If pressures were at 0 psi after the evaporator failed, when it is time to pull a vacuum, should the service ports be opened to pull the vacuum? Because I’m thinking that 0 psi might mean that air got down to the pump.
