Great video I’m a new HVAC technician and these are the types of units we have where I work. Great information on these Bard wall mount units thanks for the great video 🙏
You probably know but thats a lockout relay the HPS and LPS go through. it also acts as a DOM timer for compressor protection and it bypasses LPS during low ambient run times or in the case of loss of charge it will strike 3 times and lockout. Same in the case of high pressure events 3 strikes then lockout(dirty condenser coil is always the issue) I think they are solid state relays so they are pretty reliable. personally I haven't seen one go bad but like anything electrical they can go wonky. Also if you have 24v between ALM and COM on the LOR you can confirm the unit is in lockout. Older Bards are great units. They'll run R22 at like 450 head pressure with a plugged condenser and restricted cap tubes for like 20 years before the wires start melting off the compressor terminals. The newer ones will lockout on high head if a ladybug lands on the condenser coil haha. Clean the coils and those units are absolute tanks. I'm surprised theres no redundancy at that site. Cheers Taddy, love all the content!
Bards are the best. A blast of arctic air into a large, open floor plan house is beyond compare. While the regular residential AC located on the roof is fine under normal circumstances, it is comforting, literally, to know that if you don't mind dropping a couple extra banknotes on 110+ degree days, you can make your home feel like a walk-in freezer within 10 minutes. There is nothing comparable.
I use to work on these.. changed a few coils and blower motors.. Currently working on going into business for myself. Hopefully it works out.. Great video as always 👍
At one of these now for the same issue thanks! Only difference is it's 25 ft in the air and the electrical portion is partially caulked in with siding 🤷♂️
I enjoy your videos and love the way you take your time and show how you do the things you do it's great for new technicians as well as old technicians always learn something new every time great job
Another lovely video brother. We service dozens of data centers with Bard units. Watching you work was like watching a movie you’ve seen 100 times, very good procedural step by step diagnostic. You’re doing great. 👍🏽👍🏽👍🏽 Keep fighting the good fight.
I just finished 1 year of my hvac diploma at technical school and have 1 semester left . I got hired by a company for the summer being a install apprentice. Is that a good place to start ? or should I find a place to take me on service calls to learn that way to become a technician??? Thank you learning a lot off of you’re videos
Check it out you don't know until you try the company so you will find out 6 months in Maybe. One year? In what your options are Let me know I'd like to know Thank you for watching brother
@@TaddyDigest I’m very green I have no field experience besides 1 year of school for hvac . So my options are limited . I just wanted to know your thoughts on starting out as an Install Apprentice ?

I wanna be the guy who figures the problems out and fixes issues on service calls in the future , but is learning INStall a good place to start for my career ? To become a successful hvac technician ?
Just worked on one of these units. The pressure switches were cutting off power to the CC. So i assumed it was a leak because I also had very low sub cool. Factory charged is 110oz and I pulled out only 65oz. I put nitro in to see if I’ll lose pressure and it wasn’t leaking. I thought I was the only guy servicing this unit so i went to the owner and asked him again if anyone serviced it. And that’s when I found the truth haha. A big company in my area serviced it and they left it with almost half the charge in it! Scammers are so annoying
Great video, very clear and informative. It's probably not ideal, but if you couldn't get a coil or replacement for several weeks or months, is it feasible to pump out all the refrigerate and Saunter repair the leak ?
I enjoyed this video! Which port top with blue hose or bottom red hose would I use to install A/C Easy Dry and Easy Seal? Thank you for sharing your knowledge.

I am reaching out to you for assistance with troubleshooting a Marvair Wall Mounted air-conditioning unit. The issue we are facing is that when we start the unit, the blower works initially, but after a few seconds, the compressor starts running and then abruptly cuts off. The reason for this appears to be that the condenser fan is not functioning properly. We have already inspected the capacitor, relay, PCB, condenser fan, and high pressure switch, and all seem to be in good working order. If you have any suggestions or ideas on what might be causing this problem or how we can fix it, please do not hesitate to let us know. We would greatly appreciate any guidance or expertise you can provide in resolving this issue. Time is of the essence, and we are eager to get the air-conditioning unit back up and running smoothly as soon as possible. Thank you in advance for your assistance and support in this matter. We look forward to hearing from you soon with any recommendations or solutions you may have. Your prompt attention to this matter is highly valued and appreciated. Warm regards,

Hey, thanks for vedio I have issues on brad hvac compressor not kik in while the fan is running I follow the step on this vedio I don't have voltage between c and y on the second step
I’m a new tech. Most of my learning is residential. But how can you tell what’s a suction line and liquid line on a commercial unit? And how to tell what’s a high pressure and low pressure switch. Thanks
Low pressure switches are the switches that usually have a blue color and they are on the bigger lines go into the compressor. High pressure switches are usually marked with red and they are the switches that go on the discharge line of the compressor which is the smaller line on the compressor.
Suction line is usually still a little larger… However, let’s just assume they are the same, then just look at your compressor and think about refrigerant flow! Phase monitors just don’t have issues! Every time I have had an issue it has been a blown fuse or other issue outside of the unit itself…
cathlab with 2 wl601L 3ph 5t, thermostat on ms2, the fan does not turn off, on the unit stage that the compressor is off, so it keeps on bringing hot air from the outside....1-already reset thermostat....where can i find a video about this particular isssue?
Tad got a question I have a 4-ton unit with a hard start on it when I check the in rush it fluctuates from 141 all the way down to 109 what would be the reason
Research locked rotor amps and what it means (vs inrush), how it is calculated, and maybe a little about the coefficient of friction, and you have your answer!
It depends where they mount them for them to seem high. But if you meant expensive then yes that is expensive, even a 208/230 3 ton straight cool Bard is currently priced at $6,200.00, last I checked
A single Bard on a container or building is a waste of money; and, yes, high for what could be accomplished with alternative brands. If you are not going to run multiple Bard (3,4,5 to 10, 12, 13+) units networked together, you shouldn’t purchase a Bard system! I don’t even know why there are videos for single/spot installs!

On a Bard or Marvair package with a TXV, where do you place your clamp thermometer for checking subcool, right at the output of the condenser?
yes absolutely on liquid line
So you're in TN huh ??

@@cesarmoore7996 Labor????????? Plus other Parts???? As Tad mentions.
@@dporrasxtremeLS3 I don’t understand what you mean. Also what is the purpose of so many question marks?
A single Bard on a container or building is a waste of money; and, yes, high for what could be accomplished with alternative brands. If you are not going to run multiple Bard (3,4,5 to 10, 12, 13+) units networked together, you shouldn’t purchase a Bard system! I don’t even know why there are videos for single/spot installs!
Why’s the thermostat so low to the floor
About to service an old bard looks like 20 years old
Head pressure 2XX and is low, let’s add refrigerant… Nothing like making conclusions with less than half the data!
