That heat wave was absolutely brutal. I survived 3 months of the miserably hot summer here in the high desert, until this heat wave came and ruined me. Saturday Sept 3rd (the day before you made this video) I got sick with heat exhaustion. I was in a 130 degree attic for almost 2 hours trying to diagnose a zoning system problem. Finally got outta there, and figured well at least I’m not in an attic anymore. My next call was a residential PM for an RTU, it was 110, humid, and no breeze. That’s when I started to feel sick. My next call was another PM. I was up at the top of my 8 ft ladder checking return air temp, felt woozy and dizzy and almost lost my balance. Could’ve been worse. This heat wave was no joke.

@@nikyjim Sure, but we are cranking the AC's just as hard in the midsouth and pretty much 24/7 from May to late September. We have a lot less people than cali for sure, but we also have a lot less power production. Cali's electric management has been a mess for decades though. Not sure why considering they deal with much less severe weather than most places. There equipment should have very long lives and easy RTE for the power companies. We have had substations here that are less then 5 years old be completely wiped out from tornadoes and the power company has them rebuilt in just a few months.

[@Transit_Biker]

I think stuff gets so dry that when you get a bit of moisture all that grit and dust just gabs onto things and it dries. We get that here in the autumn with dry weather after rain - the soil kicks up and gets in the inside of houses and cars in the windows and creates a film. Of course all that stuff has minerals and stuff in it, which can change the chemistry of the condenser coils creating a bit of a layer of schmo the heat has to get through. In the springtime we also get the clogs of pollen which its own fun adventure to clean.

[@jasonjohnsonHVAC]

I remember those really low voltages when i lived in San Diego....when i lived in Buffalo....absolutely no issues with voltage sags. It was always stable.....here in Austin....its better than California, but not as good as Buffalo. Usually 208v equipment is at worst 201v.....in the morning and in the evening it is a little better. But 195v....is pretty low. It is enough to pull in that contactor. If memory serves me correctly....you can have up to 20% less than the rating and it'll still pull in. You might want to start investing in Buck Boost XFMR'ers for those really bad areas

[@nickweir5086]

Watching your videos has teached me a few things, and I'm not even going into the HVAC trade, at least planning on it yet. It also reminds me of the systems at my current job. For example over a month ago one of the rooftop units that gets no love or attention ever failed over a month ago. Management denies it failed, even though the thermostat is calling, it's 79f+ in the store most of the time, and no airflow from the vents. No breaker is tripped and I believe it failed on high head pressure like this one did as it stopped working during a pretty hot week. I can only theorise though. I see why preventative maintenance is important, but our owners don't care as they are cheapskates. The makeline for example is very dirty where the compressor is, and it has failed before resulting in it needing to be fixed in the middle of the day while we're trying to work.

That liquid injection system looks very janky doesn't it??

And i'm trying to find a reason for the suction line check valve and can't find one. I do install discharge check valves in scrolls that have to pumpdown but the suction i don't get it...

I'm surprised the contactor pulled in not having the full 208v

[@jasonjohnsonHVAC]

There is a minimum voltage that it will still pull it in. A 24v contactor will pull in with as little as 19v. I believe its called pilot duty, which some relays like RIB will state on their relays

[@LMSILVIA]

One WIC i made and service has 198v line to line 3ph and even one of the lines is almost 10 volts under like 189-190v. How can you give warranty on something like that?

That is 5%. Marginal. BUT that was No Load. Once the comp starts, it is going to be even lower. The utility should re-tap the transformer

[@eastlandgin]

What about the air in the brand new pressure control? Too little to be of concern?

[@Brisket9392]

No way for it to make it into the system. It's such a little amount if it did but those lines should always be under positive pressure. Only way is if suction control was cutting out too low (in vacuum) which isn't good for many reasons. High side will never. Nonetheless, no way to purge those lines.

[@Brisket9392]

Auto-reset HPCOs are dumb. If the coil is that dirty, it needs to be cleaned. If fan cycle isn't functioning, it needs to be replaced. If condenser fan motor is dead, it needs to be replaced. Don't understand why auto-resets are put on these units when a HPCO event will never fix itself. Just a good way to smoke a contactor or compressor until someone gets on the roof.

[@bpark10001]

How do you know it is not the low pressure control? All the switches are in series like Christmas light string. Any one of the OTHERS could be open & you would see zero V on the low pressure control regardless whether it is open or closed. I note that despite having 3 phase power, the fan motors are 1 phase (capacitors are there). Comment about cleaning: the water flow should go in the reverse direction that the air goes, so you don't push the dirt further into the condenser (I assume the fans pull the air through the condenser). You also need to clean the blades. Manufacturers make it hard to access both sides of the condenser. Those fans should be set on hinges (with the wiring passing over the hinge axis to not interfere with opening).

[@davejohnsonnola7908]

Brian See the 5:00 mark for schematic lesson. Closed switch will show 0 volts across the contacts.

[@scott5654]

You need to pay closer attention. He actually went over that very very thoroughly.

[@kaptaintrips]

Time to go back to basic electrical class. After that, visit a coil cleaning seminar.

[@bpark10001]

@@davejohnsonnola7908 Closed switch will certainly show 0 volts across the contacts. But an open one will also show 0 volts across its contacts if there is another open one in the series circuit (the same as if all power is cut). Schematic lesson is: is ANY switch is open in the circuit, there is NO voltage ANYWHERE in the circuit. So other switches will measure as zero volts across them, even if they are open. If only ONE of the switches is open, you will find it with voltmeter checking across each switch as you describe. Better way is to put one end of the voltmeter on one end of the circuit (either the neutral or the contactor feed from outside) & probe along the circuit between the switches. When you are all the way across, you should see voltage (if you don't, the cooling unit is not sending it). As you probe along, you will find the first open switch when you move the probe to the other side of the open switch. You can determine the status of the other switches until you fix the open one.

[@bpark10001]

@@kaptaintrips Regarding the electrical class you need to go. In a series circuit, if you have an open ANYWHERE in the circuit, the ENTIRE circuit goes dead! All OTHER switches in the circuit will read zero whether open or closed. Strategy used only works if only ONE switch is open. Murphy's law operates in A/C units. There can be multiple failures! Regarding coil cleaning, it is common for a film of crud to form on the side of the condenser that the air ENTERS. Spraying water on that side tries to push that crud THROUGH where it ends up causing massive clogging. On some of the newer A/C condenser units, you can't spray water on the condenser AT ALL without risking damaging the electronics.
