Those thermostats hanging in the duct can get dirty and be a pain, but it just is what it is. I went on a call one time where whoever went before me thought they were being innovative and had passed the wire through a zip lock and zip locked the thermostat in a bag so it would stay clean. Needless to say... I was there because the unit was swinging more than 10 degrees below and above set point because the stat was insulated against the air when it changed temp. Gotta hand it to him tho... the thermostat WAS nice and clean.
wrapping in in fiberglass filter media should work well long term, even if coated pretty solid, enough air should pass through to keep it happy, turbulence is good sometimes :)

Your meter can pick up stray voltages on an open circuit since it doesn't present any load. If you really want to detect accurate voltage, you can use a small automotive lamp in line with the circuit or shunted to ground to dissipate the stray voltage. I've used this technique especially in car circuits where crud and corrosion can cause a circuit to test good with a meter, but fail under the slightest load.
good comment, but he'd need to have low current 30 volt bulbs or use two auto bulbs in series(not recommended), since most are rated about 14 volt and HVAC is typically up to 30VAC. also since it is a/c voltage, some/most meter manufacture sell a special adapter to eliminate the stray voltage. although I don't know how well they work at very low voltage(probably ok though)
@@throttlebottle5906 You are quite right. I would assume (hope) that anyone poking around inside an AC unit would have that basic understanding and apply their basic electrical theory. If they don't understand this, they have no business poking around with a meter, IMHO. Cheers!
I was once invited to a convention of a major fast food company and in that convention is was strongly stated that it is not grease, it is Natural Juices. Ya!.
the weird voltage reading was likely stray current leakage through the board and other wiring, it possibly goes through the open low pressure in series. **hopefully you remembered to turn the thermostat back up from 56F or whatever you put it at for testing :)) **** never-mind, you replaced it right after I commented lol
It’s warming up and the service calls are warming up with them! The end of this Covid era is in sight! I’m so happy that you, your family, and your business made it! I also really appreciate the videos! Thank you😁.
Yeah well im sure its the 200.00 stat down the return or 5-6 brand new package units at no telling how much each. Because i garauntee reolacing the energy management system in the 3 broken ones wont interface with the currently running ones. So i understand their logic behind it. Trust me technology is almost never backwards compatible and rarely forward compatible 🤣🤣🤣🤣
@@demonknight7965 Ehhh, depends on your industry. Some industries have backwards&forward compatibility as requirement number 0 and requirement number 1. But then again, that's multi-billion dollar systems I'm talking about here, so that may have something to do with it.
I just work worked on a condenser today myself. We replaced a microchannel condenser coil on a 80 ton Trane air cooled chiller. One of those days, everything went right. No problems at all. Microns down to 400 and it passed dwcay test. We were done by 2:45 pm.
I will tell them yeah i can fix it for you. I will need 3 sticks of dynamite, 3 cases of shiner bock and 4 1b bags of nomans land jerky from Oklahoma. Then i will call a/c repair company lol
Yeah the viper cleaner will probably eat the grease out of the bearing. (Might damage the seal. Just pump it back full of grease before you leave and next time you come back to do a filter change pump some more in it.
One of our RTUs went south on Monday, it's now Friday with no repair in sight. The most intelligent answer to my questions about it are "a sensor in the box on the roof is bad." Kitchen/lobby temperatures between 88 and 92 with an outdoor temperature in the 60s. Allegedly, the part has to be ordered, and since this is a pay-the-least-amount-possible-to-an-unlicensed-tech type of job, there's no real motivation to get the repair done. I'd be willing to guess the part is readily available if someone is willing to drive 15-20 minutes in one of three different directions to get the part. I feel quite safe in assuming the indoor blower squealing will NOT be fixed, because it hasn't disabled the system (yet).
13:15 oh yeah that nightmare with some driyers usually I put a Random piece of wood under the line just for solder it, but the driller and the tool box works too 🤣🤣
my skill level must slowly be going up because when you got 24 volts and nothing from the unit. my first thought was clo lockout then you showed the panel no clo board then i was like check the pressure switch and you did and that was it. thanks for showing the process.
My stupid ass tried a diy repair and ended up pushing my hands against the evaporator coil to try and move it a bit, the aluminum is so sharp the Evap coil didn't move but my hands did, The pain and blood taught me a valuable lesson, Do it again cause that's a fun memory now lol
95° in Coachella is a cool day, whew! Something that works great for me getting into coil area is the Multi-ladder 17’ type IAA for the big boys. Set it up in a right angle configuration and go to work, makes those kind of jobs much easier.
I don't know how magnetic those units are but they make magnets that screw on to broom handles, you could use one with a short piece of handle to hold pressure on the copper line
Does it get into the grease in the bearings? Yes. So grease the bearings. Wash the unit. Grease the bearings. Doesn't take Rocket Surgery. You can also just smear RTV on the outside of the bearing housings then wash the unit and then spudge the unhardened RTV off the outside of the bearing housings. Or use peanut butter. Technically marmalade would work too. So do chimney brushes and a bucket of nontoxic degreaser.
We still have a Honeywell Excel 1500 building management system lol. T7350's and a W7760B. Woulda gone to a JACE if they were more end user friendly for configuration and such
Not surprised the Viper Brightener is working wonders. MSDS says Sodium Hydroxide which does wonders on grease (turns it to soap incidentally, saponification), seen the concentrated stuff take caked grease off engine parts. :-)
@@SomeGuyFromCrowd Oh yes. The concentrate I buy at the local cleaning supply house is handled with some heavy duty chemical gloves. Cut 10:1 or 20:1 for the kitchen. :)

I don't think it's the nitro that changes pressure but the air moisture in the system while being open. When the temp changes so does the air inside the system. The more moisture the more it changes
I believe Carrier sells brackets for 2 different LLFD’s. Of course, the Sporlan is different. The single hole duct tie just dropped doesN’T work, especially in 100°-plus weather - the single hole wire tie is even worse.
Ever try a meter with a lo-z feature on funny voltage? Ghost or phantom voltage maybe? These digital hi-impedance meters can read funny. Switch to lo-z and it's gone. Don't think you can get a clamp meter with it though. Gotta be careful around electronics with it as it will draw power.
I spotted that also. Not sure who would have made that decision or why. Perhaps cost saving? Who knows. I've been building HVAC control panels for a long time and have never seen that.
@@robandmonasytsma4187 Is it a single phase compressor then? Pretty rare I would have thought considering the 110v in the US. Small stuff yes but not big plant like this
the 13 volt reading was most likely due to the bad stat you changed and/or the pressure switch being open and only allowing half the 24v through the circuit
Hi there. I wanted to ask, why do you have to put the temporary thermostat into the return air duct work? Why can't we just stick it somewhere in the control panel section where it is less oily. I cant stand the fact that the a brand new thermostat will become so oily and dirty. BTW, I really enjoy your videos, hope you keep on doing it.
I would think it needs to sense the room temp, which is best represented deep in the return duct. Not only is the control section full of coils and wires which all produce heat, it's also exposed to the outdoor temps. Too high up in the return duct could also screw with the results if the economizer opens. My question is, if he's dropping that expensive ass stat in there, why not set one up that can use a wireless temperature probe and put that in the duct while keeping the stat safe
Did you zip tie the wires that were rubbing on the copper near the compressor? If not, expect a call back when they short out and probably blow a hole in the copper...
Another awesome video, as a tech myself I always look forward to watching your videos. Especially to learn since there's is always something else you can learn in this trade. Curious what tool your using though Measurequick to get the CFM?

Do you find your self using the fieldpiece manifolds instead of the testos 550S I’m still debating on which manifold to go with what would you recommend
I don't get why they don't put an oil port on theses compressors , because if you wanna do it by the book , since the system was flat you should have to change the oil , but since there's no oil port what can you do eh ? Is there not even an oil sight glass either ?
Forward curved fans are problems with grease collecting on the leading faces of the blades. Backward curved or mixed flow fans are better in grease environments, the grease has more tendency to get flung off and not accumulate.
