HVAC Hacks Replaced Dead Compressor & Didn't Diagnose Failure - BUT We Did!

[@ThePete2432]

I have an option from way back in my years when I was a resi guy. If it’s not hot as balls out… check standing pressure then valve off condenser… come back in 48 hours and put gauges on… if pressure is same open valves and you’ll know what side of the system it’s on. Just a tip for you resi guys coming from me struggling to pin point frustrating micro leaks before moving up to big mf’ing systems.

[@moejoe5935]

Good looking out

[@throttlebottle5906]

don't forget to account for it being frozen/blazing hot, from things like no airflow/bad indoor blower, non-condensable contaminates. the pressures may go up or down in real life. now clearly a huge pressure loss is obviously a leak, while pressure gain could have been from frozen to hot(attic) or bad gasses mixed, but that's harder to judge overall.

[@robertsmith2956]

Why don't they put valves on the evap side so you can isolate it to remove and clean.

[@evidinha12]

I like how you have to touch the ice on the lines to make sure it’s frozen!! 🥶

Mike , really love the options, so fair and upfront.... you da man

[@Eddy63]

Nice troubleshooting as usual ... Thx

[@HERITAGEWV]

Whipping the UEI around made me think of the old school sling psychrometers! Everyone has to love leak checking!! Every once in a while you might get lucky and get one of the easy leakers … we all know that’s not likely. At times we split the lineset and braze in access ports and put both sides under heavy pressure of nitrogen. And come back to it to check both sides. It’s not the easiest method but it’s helped us find some micron leaks we probably would have never found otherwise. Sometimes micron leaks on both halves of the system. Keep up the good work guys!

So was the high pressure cutoff switch bad?

I can appreciate a guy who can find a leak…

Enjoy watching your channel! Just started in this field about eight months ago and I’ve been watching your videos every day before work. You are one of those guys that has their doctorate in the AC business. I hope to one day you get there too.

[@iwenive3390]

Please don’t

[@jasonwb6884]

What did you do with the high pressure switch? Looked brazed on. Leave the switch bypassed or did you put a tee on the exterior liquid line and use an aftermarket pressure switch. I never leave any safety bypassed unless the customer signs a waiver, and i absolutely never leave a furnace limit switch or roll out switch bypassed under any conditions for obvious safety reasons, even if its after hours and I need to open a shop and pay after hours fee. Its either replace the furance limit or no heat for customer on furnace.

[@wayneguy6043]

Why not just replace the switch if it’s malfunctioning, makes sense to me

[@gallowaylights]

00:04:32 do they have a battery door issue. I See duct tape on measuring device!

[@Jon-hx7pe]

only thing i know of that could cause a liquid line to freeze is a restriction.

[@Keith_Mikell]

The other tech could not think like a schematic. So they just replaced the condenser. Excellent work.

[@Keith_Mikell]

@@PipeDoctor Thank you for the nice comment.

Would replace the liquid line dryer inside the condensing unit The Ice on the liquid line might be from a restriction

What's the success rate on the sealant?

[@AustinAirCo]

@@PipeDoctor the next slow leaker you get to replace keep the coil and pump it with leak sealer conduct a not so science type experiment. It might be eye opening. If the sealer is good enough it should seal the leaks even though the coil is separated from the system. Place the coil so the sealer will run to those areas of the coil taking. If you use dye based sealer you'll know where those leaks are. If one brand of sealer doesn't work use another until success, time lapse video should be interesting. I've used 2 in field and in this kind of test. *both failed*

[@spaceboy7192]

Mikey..lm thinking you have a restricted or a kink in the liquid line somewhere. Liquid lines don't ice for no reason. Micro channel coil won't store refrigerant like a copper coil will. Just my thoughts..

[@Keith_Mikell]

Clogged dryer if equipped also?

[@jasontexter1721]

Almost looks like plugged up filter dryer or someone didn't open the.h high side service valve all the way

[@jasontexter1721]

@@PipeDoctor may have been what blew the pressure switch to begin with, or a semi closed service valve. if they had actual discharge ports to could see what your discharge pressure is not liquid line pressure. Ive never seen a liquid line freeze up like that from low charge, at least not when it has enough freon to freeze all the way back to the compressor. If they had a bad burnout I wouldn't be surprised if there's wax/winding material stuck in a semi kinked line or even the manifolds on the micro channel 🤷‍♂️ I've seen 5/16 and 3/8 lines on small 134a system condensors get shellac buildup plugging them from a small piece of braze that buildup and snagged pieces until it completed plugged. Freon pressures will look half decent but your discharge is 200+ degrees and keeps tripping internal overload and if they had a discharge pressure sensor it would trip/weaken it. I work on every kind of commercial and residential equipment around. I've never seen a high pressure switch trip THAT low unless a fan motor failed or a restriction occured. And Ive seen several 20+ year old high pressure peanut switches still working fine as long as the nahcineb

[@Austin23191]

Mike I have a question for ya. I have a 3.5 ton AC (oversized a half ton) with a gas furnace. The thermostat is a visionpro8000. The ac normally runs for about 5 minutes before turning off resulting in poor dehumidification. Would adding a delay on make timer in the condenser help increase run times? I already set the ac cycle rate to 1 but that didn't change anything.

[@hughholt121]

Add some outside air to the return.

[@z06rcr]

Lower blower speed from Hi to medium Hi…

[@steveoh9838]

Have the static pressure tested, probably to high. The system has to breathe. Oversized unit doesn't help. High velocity overcools too quickly with low dehumidification.

[@gtpforever]

Could always go outside the box and get a humidity sensor installed and a stat that can run on dehumidification to run until your desired humidity but your house will be like a meat locker. 😂🤣😂🤣

“If You’re Not Testing, You’re Guessing” 🤪👎 Only a Hack and a Dumb Jack 🤪 would Replace a Compressor without Confirming the Compressor was Bad🤪👎

[@bryanharayda1975]

The title of this video is very misleading, you didn’t properly diagnose the unit and having a PDF of options when the system is low on gas doesn’t make anything official. Did you ever think that maybe the filter drier is partially blocked? That would cause it to freeze up, not to mention the high pressure switch is in the discharge line, before the drier and before where you hook up the high side gauges! Wow, it’s almost as if the system looks low on gas at the high side and low side service ports because of a restriction before those points! And you called the previous techs hacks! Did you even see the drier? Did you even try to do a temp drop reading across it? Do you realize that to someone who does this for a living you look like a hack? By the way, I’m just a sales rep for a clothing chain, what do I know?
