Troubleshooting Commercial Package Not Cooling

[@techdaddy7955]

It's a voyager unit. Voyager coils don't splotches. Spray with coil cleaner and use a pressure washer. Should have cleaned coil first before dumping in almost 7 pounds of r22 to see actual pressures since head pressures were so high to begin with. The motor was running hot because you over tightened it. You should have about a half inch play in the belt. Always verify belt drive motor amps after adjusting tension to make sure its not over Amping. Not trying to sound like jerk just giving you some pointers.

[@TaddyDigest]

Good tip!

[@walterpena2430]

I agree,you need to use a power washer

[@Pacman2403]

glad i wasnt the onl1 thinkin he over tightend

[@extremeair1199]

Yes 100% always make sure good airflow and clean coil before adding refer.

[@ares3914]

Take this as constructive citizism. First before adjusting belts. Look at motor data and see the run amps. Then amp the motor with doors closed. Then adjust belts then check amos again. On a hot day you shouldnt exceed the amp rating but you should close to it. Then before charging the unit, do leak check with a sniffer or bubbles. If leak is found then you ask what they wanna do. Dont assume they want topped off. Then you need to remove the refrigerant and see what the weight is and check data plate what the proper lbs and oz are before you add. Add what you took out then add to what data plate says. What i see here in this video is a rush. No need to rush no need to put your clients or home owners in a place where they have to pay you without knowing and then a week or a month later they have the same issue. At that point they wont trust and and have to pay double. If your honest with them then gain clients or home owners for life. Build the habit in things right the first time

[@daleborg9070]

A leak was my concern as well. Pretty good leak if it took that much refrigerant. Find the leak first. Then decide what to after that. Repair, replace?

[@Nylphinx]

You don't know how much you've help me out with the information from this video, thanks Tad

[@TaddyDigest]

Glad to help Thank you so much Watching my friend

[@spacemanwithraygun3933]

I have a customer with two of these that have dumped three charges just this year. I have mentioned that it may need a new coil or unit. They seem to be ok with fixing the leak and refilling with r22 each time. The compressor area panel I always put a screw through the top of panel while the panel is leaning after having them fall a hundred times.

[@ErickHernandez93]

Power wash works for those just dont hit coil diretly and use less abbrasive fittings, I do bit commercial units 6 times the size of those so trust me pressure washers works without damaging the coils, pressures looked okay before gassing a unit man, should have just tried to clean the coils first, I always says it isn’t clean unless i clean it and make sure it’s out the way specially if it’s a customer I don’t do maintenance for, gets u out of the roof faster than breaking your head going back and forth, stay cool brother

[@Lonny-hm3td]

Man from residential to commercial is a different beat. One day maybe you can make a video about how to wire up the electrical components because in commercial I see 3 or 4 Contactors and a relay

[@Lonny-hm3td]

I hope you can***** pardon me lol

[@MegaIsok]

I’m an apprentice commercial HAVAC tech. Sometimes we run across condenser coils that have three coils like this. From what I’ve seen there not much you can do about it. We use coil guns that mix the solution inline with the water hose and that helps. We have used some heavy duty coil cleaner and that works well if you rinse well after. Also Viper has a no-rinse cleaner in a can that foams up like shaving cream. Works much better than the old green can of evap cleaner.

[@TaddyDigest]

Wow Very Cool Thank You for this info John

[@eulaliorodriguez5325]

I learned a lot for a being HAVC. LIKE MYSELF. Thank for this video.

Your digital gauges are set for 410A 😅

[@user-kr4es9qg4d]

Had the same problem on the same type of unit and just poured nu Brite (the blue stuff) on top of the coils and it pushed the dirt and stuff out then hosed it off worked great

[@DaveTheHVACguy]

I just bought the same electronic gauges...It was nice to see you have same-sorry to see the door fell forward on them-glad to know there built tuff!. One set was on 410a but I figured you would catch that later I learned about double coils...interesting! I was kinda surprised when you gassed both units before cleaning and didn't use a gas sniffer to find a leak, but maybe your customer is used to that. Did you use R22? Ever tried a drop in-less expensive! I'm thankful you got the unit running but it's not over...you got job security for sure.

[@SouthFloridaSound]

Not trying to give you a hard time, but.... Where do you think the missing gas went? Other then cleaning the condenser that was a gas and go. I would think at R22 prices the customer would have been happy to find the OBVIOUS leaks(s).

[@TaddyDigest]

I really appreciate you saying something actually I agree I told the customer it's probably time to upgrade and I got them a price Now I wonder what they'll do Thank you for watching Have a blessed day brother

[@thecleanfreaks]

Thank you for your video it was awesome, my top heating carrier three-phase unit has a bad fuse by the main power which I have replaced still has no power going in the main unit other words still not powering on can you help?

[@TaddyDigest]

If there's no power coming to the unit, if you check the disconnect and the breaker and they are good, you may need to call the power company

[@emmroot5917]

Ran into a similar situation and what we did was spray from one side with the hose and the other side we used a shop vac with the attachment at the end that has the small brushes so we're not damage the coil. Blowing the hose with one end while simultaneously sucking on the other hand with the Shop-Vac will fix you up good next time. I have the same gauges by the way. Nice content

[@TaddyDigest]

That's a great idea very cool How do you like the gages?

[@TaddyDigest]

Excellent you're welcome Thank you so much for watching. Please share the video when you can

[@drodriguez394]

i see a few issues here. high superheat is not an indication of low airflow. in addition to that, that 42 superheat is wrong too because you were mapped to 410a so your calculated superheat was off of the wrong saturation temperature. you don't add refrigerant to " bring up your pressure so it doesn't freeze" we add based on superheat and subcooling im sure you're a good guy and decent tech. but this video could be revised.

[@kevinlawson8124]

Really enjoy videos, I’m technician in Louisiana

[@TaddyDigest]

Awesome Kevin thank you so much for watching

[@jimgarcia5165]

Maybe it’s freezing out because you have the evaporator door open the airflow is not going through the evaporator coil so it will freeze up if the doors open

[@edgar20109]

Thanks for teaching

[@TaddyDigest]

It's my pleasure

[@jacquesdaoud4263]

[@SuperSincere1]

You probably should have checked the coils before dumping expensive ass R-22 refrigerant in the unit.......

[@jstacitizen]

Does the blower wheel need replacing if not cooling enough in the office? The motor was changed last year.

[@TaddyDigest]

blower wheel only needs replacement when broken

[@joejoeesqueda]

freakin awesome!!!

[@lonnieroberts3590]

Would you not want to check for leaks

[@joshuapratt4214]

Im finna be a new graduate which would be the best residental or commerical?

Is this the same with my residential package unit (electrical) mine is stuck on heat and everything else works fine

[@rocker8692]

Commercial looks funner than residential.

[@kennysinclair1151]

It is, I made the switch like a year ago

[@burtminshew4812]

Old school terrible advice is splitting coils to clean. Many manufacturers will tell you to stop that nonsense. When i spray both sides i never have an issue. Splitting coils has just been bad advice thats lasted the years. My experience is 37 years and teach. Its like that newer nad advice of checking your capacitors under load calculation.... Love your videos.

[@TaddyDigest]

Thank you for your knowledge brother

[@jessec.9295]

That insullation is going to get sucked up by the blower

[@aljanepuso]

how much of your digital gauge

[@joequixotic3039]

I learned that AC units are not all that complex. A friend of mine did a school/apprenticeship for HVAC but quit because they kept giving him the dirty jobs where he had to go in dirty crawl spaces and stuff. I don't blame him because another friend of mine died from a respiratory infection he got doing HVAC in a crawl space... After seeing this and a few other videos, I'm more confident that I can install and commission (is that the word) the mini-split AC I want and I don't have to go with Mr. Cool DIY. I can get gauges, a vacuum pump, trim my lines and evacuate them by myself. I'm building as much of the rest of the house as I can so it's good to know I'm not going to have to pay a tech to install it or maintain it.

Wait till you mess something up you'll be calling someone alright 😂

[@TaddyDigest]

lol 😆 🤣

[@joequixotic3039]

@@influenz1490 I'm a metal fabricator gone amateur and "plumber". The only thing that worries me about AC is the wiring but it doesn't seem like it's networked, just analog signals which are easy to diagnose. Anything that doesn't require an IT professional to troubleshoot is ok with me. Eventually I'll try to tackle home networking but I'm prepared for that to be a work in progress for a long time.

You digital manifold was set to r410a but you said the unit was r22.
