Take it from an OLD Ammonia Service Tech.... That was great info for the general upcoming Service Techs.... Good Job..

Just wanna let you know that your videos have helped me tremendously for my diy HVAC and electric subpanel installs. Explaining things concisely and without the "I'm smart" attitude. Thanks brother!

You are a good man for sharing your knowledge and putting yourself out there for criticism from people who think they know what they don't!! Great job. Respect

Great video. I have been looking for something clear and to the point to help me explain to my newbies what the pressures would be on a typical New York summer day.

Thank you for the video it does help now with this new high tech tools we need more young technicians like you great job

Will come in handy every year when i do my inspection of my unit

What I like is that you clearly showed that ambient has an effect. When you toggled to line temp it was above 65°. These lines go underground or through very hot attics.

Thank you for your reply. please keep the good work and sharing videos.

Good video. Keep up the good work. We all enjoy learning more about the system. Thanks

Great job guys. Keep it coming.

Super helpful, especially since he uses the new gauges.

Good job, nice info presentation. Keep it up!

Nice, neat and concise explanation - thanks!

Very good. I'm an old timer and needed to confirm 410 pressures. Going out to blow one up. Thanks.

great explanation young man

Awesome videos!! Las Vegas ambient temperatures are crazy high 105-120 would like to see videos done in Las Vegas where heat is crazy

Very good video, thanks Ben

Thanks for sharing your knowledge. You video was very helpful

The pressures for a 410A refrigerant depends alot on ambient conditions. A 40°F evaporator would give you 118 lbs on the suction side or low side. On the high side and a 95°F ambient temperature you'll generate 295 -300 psig or lbs on the discharge side, or high side

Awesome explanation, thank you

I like that refrigerant analyzer tool, i wish i could have someday someway.

Nice easy explanation. 👍🏻

Replaced a heat pump and evaporator coil in a 3 ton air handler with 3-ton equipment. Needless to say I had to switch to a piston ( high head lockout) ... Had the right txv for HP. I thought it was airflow. Had great pressures with the piston. 21 degree temp drop and my 12 degrees. Watch out for that. It is new to me and I had to eat an a coil on that job.

God bless you keep going i see a brilliant future for you

Best video I have see. Yet

Thanks amigo easily explained

Good job guys appreciate it

I love these videos. Even tho I don't run residential anymore but it's these types of videos that give the homeowner a lil bit of courage to try and fix something they know nothing about. In turn they generally make the situation worse and that's more I would charge to fix the initial issue....plus what they jacked up

Awesome job thank you

Thank you for the video!

Very helpful love the vid

Great human being.God bless u Sir. May I please ask a question tho ..When the heat pump is heating inside..what side on the outdoor shall I take my air on and off the coil...I'm still an amateur in this game.Thank you very much.

Very good information bro keep it up God bless

Great video!

Nice video man.

Morning Benjamin. Just enjoying your hvac videos again. 20 yr old rheem r22 system. It called out only liquid line pressure for charging. Not subcooling. Should I use the liquid line pressure to adjust charge? Or set subcooling to 8-12?

Thanks Ben. Please do a video on a R410 Mini-Spit. Pressures... Temp's...

Muy buena esplicacion mi amigo👍

Hi Ben, I have a 3.5 ton 14 SEER Goodman packaged heat pump on my house, I'm pretty sure I'm on borrowed time considering I had this unit put in back in the summer of 2009. I noticed lately that almost my entire compressor, the entire accumulator, and most of the fixed metering device is completely covered in condensation, I live in Florida and I assume a lot of this is due to the high humidity here, I also noticed that the insulation under the top cover of the unit fell apart. About a week ago I cleaned the condensing and evap cores on it, the fins on the condensing core are flaking off in a few spots due to the age of it, but nothing super excessive, the evap core is still solid. I had been noticing the compressor was much louder on start up and even when running was a bit louder than it had been, I replaced the dual run cap with an Amrad with the CPT terminal, the cap is a 45/5 mfd, I put a 5-2-1 hard start kit in it with the separate potential relay, the contacts on the contactor looked a bit burnt, it was still working, but I replaced it just to be safe. I did notice after replacing these items the compressor starts up faster and quieter and seems to be running quieter too. I noticed that after doing all of this that the air blowing off the condenser fan isn't as hot as it once was and there is less condensation draining out of the unit. It is still cooling my house and has cold air coming out of the vents. The cap and contactor I replaced were the factory originals with the unit, I tested the original cap out of curiosity and it is supposed to be a 45/5 but it was only giving me 29/3 mfd's. Could the compressor have sustained some damage from running with a weak cap all this time and is this amount of time and is this amount of condensation on it normal? Would the fact that the insulation on the top cover of the unit is gone have anything to do with this?

Good job Guys

nice gauges nice quick review. what brand wrist watch do you wear? thats what im looking for

Thanks

thank you for this video

The range of pressures for R -22 in the Low Saturation Side is also from 38 to 45 degrees or is it just for 410 A? Thank you for the video

Sir , you are an icon of what an achievement is . The young should look at you and learn that mind is a terrible thing to waste. For all those who walk with their pants falling from their butt, I say watch this young man what he does with his life , and what you all doing to your lives . Thank you young man for being who you are , a model for humanity.

Good man Ben

Good job 👏 👍

I wish all A/C service people were like you and not try and sell a new system everytime we call them..

Thanx

Could you explain 410 A without digital gauges Charging procedures

It’s so funny the young guys coming in the trade have to have the fancy and color coordinated hoses and a set of $600.00 gauges to work on basic a/c residential units. I am retired service guy that worked in all aspect of refrigeration from drinking coolers, super market and industrial refrigeration to house hold a/c’s. I have been retired now 6 years now and I still carry a PT card in my wallet and use basic gauges. Young people are a trip

Hello ben. I love your videos. I have my home that it doesn’t go lower than 76 during the day Subcooling is at 11. I have a delta T of 14. I dont know what else to do. Please help me. Thank you

Nice

Ben I have a 4 ton 410a Goodman and have to add freon what leak sealant do you recommend for leaks if any

I never went to school. Was SH and SC taught back in the day? I learned coming up through the trade. 20 yrs ago it was rule of thumb. ( At least that was the way it was taught to me ) Once i learned SH and SC i became knowledgeable and proficient.

Sshhhh. You’re giving the secrets away bro. You’re going to make these DIY guys technicians. 😂😂😂

Reminds me of me when I was a young buck

Cool!

The most important concept in refrigeration is to realize that pressures are a consequence of temperature. Heat creates the load that causes pressures. Knowing pressures without knowing refrigerant temps (superheat & subcool) is less than half the picture and impossible to make a diagnosis from.

hey there a friend of mine just bought me a set of gauges analog in celsius but its ok for getting his unit going last week ,, i am retired at age 67,,, times has changed now with utube etc etc those fancy gauges you all have we had to do it all in our heads ,,,,but we did it ! i liked what you showed in trying to teach my friend so he would get a little of it,,,,AAAA+,,,love it , its all good ,,,,how much do those gauges by the way ? the set he got me for helping him he got on amazon in celsius is why they where like 39 bucks ,,,,just saying , better then nothing ,,,,

We REPLACED THE INSIDE Coil IN 2010, the 2ND FOR THIS BRYANT/carrier 5 ton. {410A} 2001 model was was made in Mexico rusted and leaked badly made like crap for old refrigerant bad welding smaller tubes. This second has been serviced 5 times and leaked also. Have spent over $1500 in bills for its 10 yrs. Now 2 mos ago was filled for $400, by my wife, by a P>O> S> AC contractor. It has already leaked out and the lines are frozen. The inside blower capacitor went out. Changed it and using only blower fan till we find leaks. I hate these sad excuses for quality. A replacemnt coil costs @ $1000 they had a 10 yr warranty.

Hi! Amazing video! Thank you for creating this type of content. I recently installed a new Rheem 16 seer 3.5 ton system (RA1642AJ1NA + RH1T4821STANJA) at home and pressures are low side 140 /High side 305 at a 81F outside temp night here in florida. During the day with 92F outside it was at around 175 on the low side and about 300 to 310 on the high side. Does that mean Am I low in refrigerant? The system is cooling but I feel it takes too long to lower temp inside. Like 1:45 or more to go from 72 to 70. Any advice would be greatly appreciated, thanks in advance.

Thanks!!! ❤❤❤

Very good job!!! I have a question...can this unit be adjusted to a lower evaporation temperature ?? ...hence.... to remove as much humidity from the interior ? Thanks

Thanks a lot Ben! My new Carrier set with TxV added by a "pro" but he doesn't use nitrigen and soldered at least three times due to leak, he roughly powered on to get cool and escape. I then measured SC is 5.6 not 10 and half a year later I see SC=0.5 and Low/High 117.5/307.5 (out 80F), I added a bit and see SC is 0.5-1 back to 0.6 and Lo/Hi become 120/298, what would be the problem?

So what would be the correct reading on the gauges with a 410a Compressor model zp38k5e-tf5-130?

Hi . I packed a small bottle of 410, the size of 800 g. Note that the manufacturer wrote in the outdoor unit, the air conditioner is 710 g. Only When the flask was completely filled, a white layer appeared on the intake pipe. But the scale indicates 70 psi. The air conditioner works normally except for an annoying loud sound when the compressor is running.. What is the solution respect the scale (710g) according to the manufacturer Or play until it reaches about (120psi) thanks

Ben, I installed the components form a 410A dehumidifier into a 1905, oak ice box. what's your best guess at what the high, and low pressures should be? It seems to be pretty happy at 90 psig on the low side, and 330 psig on the high side. I find that these pressures change dramatically depending on ambient temp. Thoughts?

Your video doesn’t show up in my subscription feed. It’s only showing up in my notification section

Thanks for sharing. At 85 outdoor temp what was the supply air temp at the registers.

question my unit is having a issue. condenser/fan is cutting on and off .. air handler is running fat checked stat batteries theyre Good i jumpt y and c at stat and yet condenser/fan did same cut on and off. I turned off cool on stat went out to condenser pusht in contactor compressor sounded normal but the fan wasn't kicking on. the start cap doesn't have a wire going from fan to cap .. its a ecm motor.. what could be causing this is issue? gauges w unit off read 125/250 that's low/high side manual old school gauges was about 75⁰ out w humidity here in north east...

Hi benjamin,what is the common trouble of the TXV or thermostatic expansion valve,,,anyway im edgar from the philippines also a ac technician

At least you are honest !

Great video, the only thing I would have discussed was what subcool readings should be.

where you make your service ? Are you also service as an electrician ?

also in class years ago we where all told that HVAC is not 100% correct science ,,,,anything within 3 degrees is acceptable in this trade ,,,,,this comes from a teacher at the time who had 35 years in this trade in today's time add another 25 years ,,,,,thanks guys be safe

What are the non operating pressures of R22 and R410? when the unit is filled but not running?

So superheat and subcooling I never heard the terms you used

Isn't there a reference chart inside the cabinet or isn't there a reference chart that come with the refrigerant, so you can check pressures as they should be based on tonnage of the unit (3 ton unit I'm my case) and ambient temperature 98f the day my unit installed. As ambient temperatures increase so do the pressures, which my techs failed to do. They based their pressures on a normal day like yours, my accumulator sweating like crazy, and worry, pressures too low. Dealer won't check charts to make sure pressures are where they should be.

you good

Thanks for your explanation it is profesional .what brand Dig monifiled gauge you are usig?

Hey Ben thanks for the explanation on ambient air temp, vsat, and lsat. I sprayed down my outdoor coils with water on a sunny hot day while the unit was running. Since these coils are high pressure, did I just do damage by spraying cold water on it while running? Thanks for any feedback.

What should be suction pressure of normal mini Split inverter R410a system at 110 Degrees Ambient temperature????

Hi Can you please make a video how you charge R410A Refregerant on mini-splt systems Mitsubishi, DAIKIN or at least fujitsu I'm EPA CERTIFIED MANY THANKS

Do you have to add oil to the 410a system or is it included in the refrigerant.

So, what is the maximum pressure that an evaporator should be capable of using r-410A?

Awesome video thanks! Would you consider a private course on basic hvac? If so I’d love to subscribe

I get lost on knowing what metering device the system has. I always run into systems that don't have easy access to view the coil. So i never know what im working with a piston or txv.

Artist

Big blue and little red lol How it was first shown to me 12 years ago and still How I say it when teaching new guys in the field

Hi having issues with a newly installed R410 A 3 1/2 ton unit keeps on freezing up no txv does it take 6 pounds of refrigerant like the name plate says and do you have a proper pressure chart that you can share ?

we just had someone install a our new AC R-410A and is very loud inside the house but not outside, is this normal, I just can't stand the loud noise.

Is it correct that you can vacuum the 410A out of the new unit & put R22 in to use the condenser? I have a handyman who has done that for a few years on numerous units & it all work fine. Thx

Dear can I get to know that from where this gauge get pl inform early

I thought 10 degrees over ambient was a little low.What SEER was this particular condenser?How long had it been running,before looking at pressure/temperature performance indicators? Thank you.....

Sir I've got a question, what would happen if i plug the red gauge to low oressure line? Do numbers ob both gauges have ant relationship which other or do they equivalent to eachother?

You only displayed the pressures.. What were the superheat and subcool running at? Indoor WB? SAT?

Now if your low side is under freezing like around 0 to -10 would you say it's most likely a cooling coil issue or refrigerant issue? My cooling coil completely froze about the furnace got myself some 410a guages and it's not looking good for me.

What kind of guage you use bro?
