Oil is naturally clear to yellowish.....Good Job

[@michaelmckenna9022]

Having a breaker close to the load is always a good idea.

[@hangfire5005]

From my training, OL on your meter stands for Over Limit and it means that the measurement is beyond the range the meter can read. In industrial stuff we use a megohmeter or "megger" to test winding insulation of motors. These use much higher voltage (usually something around operating voltage) and can read the very high resistance between the insulation and ground. It's used to find failing winding insulation before it fails or to test an unknown motor for failure without just putting the full power to it in a live circuit.

[@gilbertopatino2616]

😱

[@michaelmckenna9022]

@@hangfire5005 An ohm meter uses 9 volts to measure the resistance in the circuit. I use an insulation tester. This meter puts 600 volts through the circuit. Sometimes when there is a short in a circuit the voltage spikes up very high.

Cancel all your other HVAC youtube subscriptions, TAD is the only authority you need! He's the man! Very descriptive, very thorough, very honest. Thanks Tad, #giveaway

Heck that FPE stab loc load center needs to be changed out as its a fire hazard. Great video as well.

[@fredm1988]

I'm an electrician not HVAC but I appreciate your ability to teach and your personal approach to your customers

[@grundyb]

Thanks so much for cutting everything open to see the insides. It helps so much seeing the insides after a failure like that. I’m not a licensed HVAC technician but an old technician for manufacturing plants and sometimes I worked hand and hand with the HVAC guys when they were overloaded or needed help lifting the heavy equipment. I’m in New Jersey. 👍🏼

[@chrisscott1547]

Capacitors usually die from heat, and so do compressors but the "enamel" coated wire used in the windings (actually formvar or other) can be killed by over-voltage transients. Otherwise known as nearby lightning strikes. A nearby (less than say a quarter mile) strike can hit power lines, or magnetically couple to power lines causing thousands of induced volts for a millisecond or so. Over time this can degrade insulation to the point where 240 volts will arc through causing a short, often to chassis. Sometimes you will measure a couple of Megohms of leakage resistance from the windings to chassis and wonder about it's health. This sometimes leads to condemning it, perhaps needlessly. But it may be an early warning that further compressor life may be limited. Over-voltage protection devices can help. These are typically metal oxide resister based, and are placed across the 240 ac. When voltage above a threshold is presented, they shunt most of the voltage, sometimes sacrificing themselves but saving your equipment.

Compressor class has started! Thanks Tad.

[@davidperry4013]

Scroll Compressors should've been standard equipment on systems since 2008. They have fewer moving parts, are more efficient, and are more resistant to slugging.

Great video tad. Long time follower, journeyman commercial technician… i love seeing a good educational video. One can always learn something, don’t care how long you been in the field. Thank you 🙏🏾

Great job tad always learn from your videos thanks again

Amazing work Taddy , System cleaning is the most important method we need to do before putting a new compressor in every cooling system.

What is the problem with the Federal Pacific breaker box? One of the most prominent dangers of a Federal Pacific electrical panel is that the Stab-Lok breakers are prone to overheating and malfunctions. Current estimates predict that faulty circuits from a Federal Pacific panel are responsible for nearly 3,000 residential electrical fires every year.May 2, 2023

Awsome! Never know there are HH and suction line filter dryers! Also the acid test and the anti acid stuff.

Talking about Terminal venting..the most common issue I have noticed is insecure wire connectors on the Terminal.this Will keep the Terminal arking and overheating which will eventually melt off the glass seal around the terminal

Would you need to change out txv? I know some have screens in them.

[@mxslick50]

Good video. Minor note, OL on the meter means Open Line (throwback to telephone days) not Open Loop. Unless I missed it, whst was the solution you used for the FPE breaker?

[@WallaceRoseVincent]

Why are package units in my area (3.5 ton), $12,000? It's a heat pump. That's what my neighbor just paid.

[@leiferickson713]

It looks like BP was drilling there.

[@arthurrabon9349]

what is your opinion on soft start add on. did that unit have a hard start.

[@TaddyDigest]

love soft starts this unit did not have a hard start

[@mxslick50]

It's FPE, Fire Prone Equipment. that breaker is only a switch (and that's questionable at best.) To be fully Code compliant, the new disconnect must be rated to 100 amps, with the appropriate fuses for the condenser. Best option (and cheaper) install an outdoor 100a main lug subpanel with a breaker sized to the condenser.

[@TaddyDigest]

Thanks for the info!

[@ablejohnson]

Bad ass

[@thecreaturesdancedlikeus3922]

Another good one Taddy🤘🏽 If they did go with the compressor change out and follow all the steps, on the next visit out you install a pipe where that filter was would you go ahead and give the unit new refrigerant?

[@davidlopan6649]

I would replace a whole new line set, evaporator coil, condenser if there was acid in the system. I don't trust those flushes.

[@TaddyDigest]

Great question yes that's a good idea

[@davidlopan6649]

@@TaddyDigest Taddy! What's up brother? Love your videos! Keep them coming!

[@jstasiak2262]

What wire gauge (AWG) was running from the main service panel to the outdoor disconnect panel? To use a 100 amp circuit breaker in the service panel, you would need at minimum AWG2 THHN wire for such a run. That is extremely heavy duty wire that is normally not used for such a run. For a 35 amp sub panel, the minimum wire size is AWG8. Usually such a run is wired with an AWG6 or AWG8 wire. A 100 Amp breaker is too large to be used on a circuit that used AWG6 or AWG8 wire. Did you take this into account?

[@TaddyDigest]

I'm pretty sure there was a 6 awg wire. I don't know what was going on with this, but I know back in the day. They did things a lot differently, then now

[@OcRefrig]

@@TaddyDigest yea, back in the 80's code was 50 or 60amps for #10 wire. i know. i installed 10 Ga whips back in the day for 5 tons. code inspected. They made the code stricter over the years. i started in 1981. about 25 years ago they dropped 10Ga to 30amps. was 50 or 60amps. We never had issues at 50 or 60. i think they had some issues with resistance heat though. Terminations melting at Lugs etc.

[@Louisyongcool2328]

When you replace the liquid drier do you re use the gas?

[@TaddyDigest]

Depends on the condition

[@chetmyers7041]

Couldn’t it also have been a failed bearing?

[@OcRefrig]

Good vid ! FPE Lost thier licence because of those STAB-LOK Panels. i Hope You or someone checked that 100 amp breaker in that Stab-Lok panel. i Would Have an Electrician install a Smaller Breaker in that Panel ! Definitely Check the Bus Bar. it's Highly Doubt full that 100 Stab lok Bus bar survived that compressor meltdown. Those Stab loks Don't handle 40 amps let alone 100 amps. FPE Panel Should be Replaced With a decent panel. Major Fire Hazard. FPE Panels are Junk !!!

FPE is All over the Net class action law suit , house fires , can't sell a house with Fpe panel. etc.

[@paulb4496]

Most fluke clampmeters do not have a sensitive enough ohm function (10 million or higher) to find a compressor that is starting to go to ground. Fluke owns Amprobe...the original amp clamp meter company. Fieldpiece, Ideal, UEI, Sperry. I have owned all these brands. Fieldpiece and UEI are most durable. <a href="#" class="seekto" data-time="493">8:13</a>

[@jonnywow2585]

It could be just bad motor that shorted , I’m am not an ac guy but seems like new equipment doesn’t last long not bc of installation faults but rather cheap components and the amount of labor cost all those extra and right manipulations won’t guarantee the cost , no one gives the 100% warranty
