That's true but I wonder if return air is causing a faulty LS reading. If it's 92-95 OA, I could imagine it having an 80 RA or more.

I believe he mentioned he had a txv, maybe possible issue sensing bulb issue. No contact with suction line? Could be dumping more refrigerant in evap coil not allowing high side to come backup. Could...

That's a good plan.

Your right about heat radiance from coil if too close, I'd say stay a couple inches away. Besides fan pulls air thru the coil, doesn't push it. The shade makes a difference, especially when it's...

Appears the system is low on charge, your pressures are too low for ambient temps to begin with anyway. Liquid should be warmer than outside air temp. Both lines are cold so your compressor isn't...

Depends where the condenser lays, is it in the shad or the sun? Normally you should take OD near the coil air intake.

It's been awhile... but I'll take a crack at it. Back in my day I would've pulled the charge and weigh it. Checked the piston sizing if there was one with the manufacturer of condensing unit. Charge...

If really concerned I would make a second approach to the foreman verbally. Make it known you're looking out for the company and you want it to be in good standing with the customer. I would not go...

Recently I was give this nifty little attachment for a hose by my boss. I was pressure washing an aaon condenser coil/ chemical and all. Probably 3" -4" thick. Thought that must be pretty clean by...

Good point. Ah I thought I'd throw it out there . o thought about it the fact too.

Love the bag battle. Hilarious!!

The OP definitely lacked info but I have a strange suspicion you guys just got trolled.

I don't know much of anything about vfd's. Would it be possible to have fussable links to each motor? In case once does burn up it doesn't take out the others in operation or cause vfd to fault . ...

Great job. Here's one seeing a couple have stories. My buddy came across a ten ton Goodman I believe. He said there were 4 guys before him for a no heat call, 1 guy changed out contractors didn't get...

Techman has a good point too. After a while you get quicker at diagnosing, these are all things a tech that's been doing the trade examines first. It's the same way I've been approaching issues my...

Penderway, knows his sh*t. So does jay guy. Those are 2 guys I like seeing their opinion on discussions. Everyone keep those guys in mind you'll learn a lot of fine detail.

You need to take care of the obvious first before you prematurely diagnose the issue. You said the evap/ filters were plugged?, clean it. Check condenser, can you see thru the coil?, I high doubt its...

I see. I've installed them on new installs or if I get the chance I like to install them doing a repair. One thing I don't do is count on them to properly charge a system though. I still go by sh or...

I'm not hip to the abbreviations, I'm not cool like that lol. SGMI, what's that stand for?

I mean don't get me wrong I don't believe they're pointless just never got around to buying one or needing one.

Jtrammel,

To each his own buddy.

Don't pay attention so much to the sequence of voltage, that's an example. OP stated he got 208 at all 3 terminals on the compressor, that means he lost 2 legs of power somewhere. I've never seen 3...

Here's one for you " what not to do" . I worked with a guy who was changing out a service disconnect live, 230/ 3. This is when I was fresh in the trade. He said changing it live is what separated...

Don't ever believe that a circuit breaker is fail proof, I've seen it too many times.

What is with this PECKERHEAD terminology I've been seeing in here lmao!! U guys are too funny sometimes! Is that really what it's called or you guys making fun of the OP?

Why would you get 208 on all 3 legs, 208 is the stinger leg. On 3/phase 208 you should have 125/208/125v. Am I missing something here? I ran into this problem once where I had correct volt readings...

Like I said IMO, also doesn't mean I've done it wrong for xx amount of years either.

I personally never removed the shraders when vacuuming down a system, nor have I ever triple evacuated a system like (410). IMO I don't believe in triple evacuation, the point is to remove the non...

Sounds like you maybe over charged. Is the condenser matched with the evap. Is the seer rating the same? I've worked on at least a dozen splits where someone had installed a new 13 seer condenser to...

From what it reads like, you turned the power on and started yanking the wire on/ off the comp terminal and checking voltage. Buddy that takes big eggs to do. An arc flash alone could peel the skin...

I would agree with the beer guy. A system can be cooling perfectly fine but you will have an abnormal head pressure.

Its been along time since I've been in trade school, and can't remember why... But there is a formula that will give you a ball park figure what you should be seeing. However you should check your SH...

Bet what's screwing the system up is either the filter drier that's probably located inside the condenser, or the cap tubes running from the txv valve are partially blocked. In the future when you...

Check your coil outside and make sure its clean. What I would do is recover the refer't, cause it sounds like you have a leak somewhere anyway. Your system is low on charge to begin with, take apart...

I like my imperial set ( 5 years old and just recently rebuilt them). Is that the digital set by field piece your talking about ? The more complicated things are made the more aches they are.

Equalizer tube is to unload pressures in coil from high side to low side when a/c operation turns off. This is to prevent overloading compressor on start up when theres a call for cool.

And yes start bottom joint on vertical txv first. A little extra prep time and thought takes less time than to do whole procedure over again.

I find that its easier to braze one end at a time on a txv. I spray the power head and body with cool gel , careful not to get on the joints, I'll braze one end. Take wet rag and wrap around txv body...

Wow that's crazy KB cool, about the 10ton circuits mixed up lol

Recently I've heard many companies trying to enforce a predetermined amount of time it should take you to replace components not taking into consideration the difficulty level. Every job is different...

I've been doing this for only 8 years now and I'm tired of getting bent over myself. Companies have no appreciation for your efforts. I used to work crazy hours and kill myself. till my back started...

You are correct timebuilder. You will always get voltage at the other where your common is supposed to be connected. 230,120,24v and so on. Resistance of coil will not degrade expected supply...

Sounds like a restriction. Not too familiar with them, worked on em and fixed em but not a fan of em. Someone should chime in soon that has better knowledge of that unit. If I were you I'd get down...

I've been down that road of matching splits, in my opinion your better off sticking to the same tonnage. Otherwise your gonna open a can of worms that you really don't wanna eat. Also take into...

Either you lost the 24v. Common or your getting 24v. on both low volt wires to the contractor. Disconnect both and test each wire to ground making sure your reading zero on the common side.

The company has a client that has several stores, complete pain in the arse. It was 85 ot the other day
And manager said a/c worked perfectly ( nice and cool). Yeah right. Found 2 new furnace and a-...

I will say that the ability to inspect and clean the inside area of a coil is an issue, makers definitely don't make it easy access. They have a removable plate but how ya supposed to get it past the...

Id check the ifc board for burn marks on the back. Sounds like low volt is dropping out for a split second, to quick to notice with meter. I does sound like board is screwed. P.s. fault code,...

In these cases I usually break out my hook n rope and scale the side of the building. Throw on my harness with my broken lanyard from a similar job that I had fallen off the roof, its still good....

I'd probably cut the hs line - pinch n cap off. Keep gauges hooked up, service valves open on condenser and cycle. See if hs psi goes up immediately, if it builds slow or nothing at all then its...
