Both gas station and store are back to corporate setpoint of 74°, Now subway knows where there switch for exhaust fan is.

We are good. Made it to the roof. No harm to people or equipment... one thing I've learned with hvacr is not every job will be picture perfect. The lifting strap was under its lifting capacity. And with the tie off, I had 3 points of contact on the equipment at all times of the lift...

No, the board will fault out. First thing I tried.

10-32 set screw

We charge $60 per lb of 427a and do not stock or use r22...

You made a spelling mistake. “ass” is not correct. “as” is.

@@suezq74 no I didn’t half ass is what I said

I don't carry r22 on my truck anymore. The only option with me is to convert it over. OR new equipment depending on what is wrong with it...

Update...MOST techs are honest, poorly trained perhaps but they believe what they are saying... it's the owners who send them out that are ripping you off..

427A is designed to be a 'drop-in; R-22 replacement that has very similar pressures and requires no changes for existing R-22 systems. Basically a new production alternative to the shrinking R-22 supply and crazy prices yet I barely knew about R-22 replacements as someone not working in HVAC and was just concerned about new AC unit prices if our R-22 system developed a leak. R-22 was used in AC units until 2010 when it was replaced by 410-A in all new units, but 410-A runs at higher pressures than R-22 so they're not compatible and you need to find a certain R-22 replacement like seen here that can be used in pre-2010 AC units. This is basically the alternative to having to buy crazy overpriced new equipment if you have a repairable leak.

No long video. Dryer was inside next to airhandler and was replaced. Everybody hacks stuff a time or two, so when you say you not a hack, understand that some jobs can not be completed to perfection depending on the customer. Im not a fan of blending gas. This particular gas station has its own repair men, not sure if they don't handle r22 or why I was there, but my job was to get that unit going and did just that.

427a is a direct drop in replacement you can add it strait to R22.If you have a TXV might have a very slight temp glide will be fine.How about you post videos of your jobs since you’re so by the book show the rest of us how great you are

@@DallasPhillips-hz9yn Where does it say you can blend refrigerants?

@@WhowereEpsteinsclients direct drop in what part of that don’t you understand?what do you think for example R407c is a blended refrigerant. It takes like three refrigerant to make 407C.

@@WhowereEpsteinsclients what part of direct drop in don’t you understand.407c is a blended refrigerant for example.takes like 3 refrigerants to make R407.It runs the same type of oil made as a direct drop in boiling points arnt far apart anuff to matter

You must be a zionist?

Believe dye and moisture...

@@hvactoolporn188 xD

It would of been quicker 😂

Itd be nice if they made a vest that you can strap a compressor to so all you need to do is use your legs and 1 arm

Great advice...

We replaced contactor and micro switch and 2 days later ordered a Dainkin unit. We are experimenting with gutting controller on a few units but have not made a final decision to what methods we will use in the future....

Bottom contractor is actually circuit #1. Schematic is labeled wrong. Small compressor is 1st stage. Don’t ask me how I know. Had this exact issue and scratched my head for awhile. Check incoming voltage. Trane taps all their transformers for 240v. Had to tap the transformers for 208v. Haven’t had a single trip since. My control voltage went from 23.2v to 27v. Tranes are super sensitive to anything below 24v

Yeah we replaced the switch and have not been back..

Anybody having issues with these units not dehumidifying in 1st stage cooling? 33% cooling capacity and 66% fan speed. 50+ degree saturated suction temperature not below RAT dew point. I’ve lowered the “max fan speed” as a temporary fix but then when unit runs 100% cooling capacity it like 230cfm/ton.

So when I fixed it I ran like you said. To the 2 poles of a 2 pole run cap and did away with the blue wire! Common wire strait to com on compressor red hot leg to cap and to run, and then from start cap to 2nd pole on 2 pole cap and to start.. fixed it rite up.

@@hvactoolporn188 yes you saw it my friend! They wired it funny. Right on, yeah looking at it I was like wait a minute?

Yes temp controller. 28 off 38 on. Not sure what the model is in this case I have only worked on a handful of them. I went over the wiring and even stepped back and went over a second time. Could not find it.. improvised with the hard start when I realized the run cap was only rated for 220v and was 240. The customer has their own repair guys so no clue what they did to it prior...

I'm a old tech from Arizona originally. More residential stuff. Have worked on some wine units in the past with these kind of components. Cut in cut out differential timers, did you find a open or damaged start winding in the compressor, or was there already the start cap in place when you arrived? That is always sign of previous compressor damage. Did you also find a damaged fan motor, like really high fla, full load amps on start up? Or a overload popped out in the fan motor from over heating? That relay burned up for a reason. Stuck bi metal leads internally perhaps from arching over time?

So when I arrived breaker was tripped, the relay was shorting out, the fans were .2 a over fla and ohm on the compressor was within range. The new relay I received was stuck and would not cut power to the start cap.. so I was the one that flipped switch and popped the cap.. instead of going back to parts house 35 miles away I used the relay off hard start and cap as start components. The system ran fine and the amp draw was on the high side of the range but ok. Got down to temp. Management stated their repair guys have worked on it several times this year. Seen new filter and clean coils.. was wired correctly so not sure if the start cap was feeding back but didn't need to dig in further as I wired around that with the hard start.

No contactor on this type of system is a southern case art reach in deli case.

So the relay was not opening power to the start cap. Is what made it overheat. Replaced it and that is when it blew all the black oil out... I wired a hard start with a relay and is good to go as it took that og relay out of the equation. It was a 240 system and the start cap was rated for 220v the hard start was rated for over 300 volts and gave me a relay to cut power to the start cap...

Think that was turn on off and to clean 3 times to reset

First time using it this year. Coil Was washed 3 weeks prior. 1 block from landfill so I figured if pressure didn't drop was going to pull the charge and use virgin gas.. pressure dropped to comfortable pressure. I was pleased

Just the visual of the growth of stuff on surfaces.. cubed ice is dirty.

We didn't sell it.. just trying to clean up the mess...

Nope but that is what insurance is for if it ever does happen...

How are you running the blower?

Nope, it really isn't.

Not really any one that knows a thing or two about HVAC will get it. Typically you use a crane we pushed it off... Google how much does a 5 ton package unit weigh and most are 500 ish pounds...

Thank you! I was trying to think of a way to tell them the icp units or Grand air 5 ton package units only way around 500 lbs...

Ask um how long it takes him to drive to Florida to open it for me...

Hmmm would the drop cloths be used like a parachute?

I did a package unit today. The thud is really satisfying.

That would be... your fired!
