Jim is a teatcher! Best regards from Brazil Jim! here is summer time! 38 Celsius now !

[@JamesPettinato]

+sergio graf lucky you, thanks

[@arniegrote319]

Nice Job Jim, We had temp about -14 last week, I had a lot of low pressure problems. Man was that FUN.

[@JamesPettinato]

+Arnie Grote Arnie you have all the fun up north, careful, Tim Allen might fall off your roof and you are going to have to be the "Santa Clause"

[@arniegrote319]

I hope not.

[@kena6524]

Jim, you're an iron man!! I live in New England and deal with temps pretty low. Working on roofs is a bitch! You do it just like it's 70 degrees out. Awesome work!

It's nice to see Mr. Pettinato enjoying a brisk day on a rooftop in Cleveland, Ohio.

[@JamesPettinato]

+Rj Morgan thanks

[@rickl5938]

So Jim - You are a great refrigeration man. You're focused on your customers, know your stuff and very skilled. I would like to know a couple of things: 1). How the heck do you get those heavy compressors up on the roof? Do you have some sort of lift? ( I know how you get the old ones down. Saw you kick one off the roof. Lol ) 2). Do you ever get a holiday off, or, for that matter, do you ever take a vacation? Thanks.

[@romtopinstal7870]

Nice work Jim.

[@bormorzx]

Great video. Question, why not to do a pump down system??

[@zack9912000]

Feel you pain, work in Cleveland all the time for a industrial air compressor company as their HVAC tech. Freeze my butt off every year

[@JamesPettinato]

+zack9912000 today I've got to work in a warm greenhouse out in Columbia Station, thanks and stay warm

[@garysmith9772]

I've been retired two years now and my wife and I were out yesterday and she said I bet your glad you don't have to go on a rootop today, I cannot imagine the chill to the bone anymore plus the danger of going on icy roofs. Good luck and god bless.

[@JamesPettinato]

+gary smith It's fun, reminds me of when I was a kid going sled riding , thanks, enjoy retirement and stay warm

[@tinman4585]

Hey Mr Jim got to love them cold days on the roof! Love your videos! 35 years in the trade and still learning in Ct area

+Phillip Groom yeah it was, a Greek restaurant, thanks

[@DarrenPage]

Excellent Video, I learn something new every time I watch, Thnx

[@JamesPettinato]

+Darren Page thanks

[@Ta-th2yo]

Nice video. You could have checked faster that low pressure cut out just closing the suction valve. No need for pump down.

[@JamesPettinato]

+Joo Pere I know, I wanted to check that there wasn't too much refrigerant in the system, by pumping the system down you can check if the reciever can hold the refrigerant, thanks

[@gonzgarr1592]

you are like a professor to me thank you and stay warm

[@JamesPettinato]

+hardcooling Yeah, it's fun, thanks

[@stevewood5447]

Great video Jim! I sure felt your pain with the cold! I'm here north of Chicago, so that lake Michigan snow an cold is wicked sometimes. I tip that I found helps me in the cold Jim, is I place all of my liquids that could freeze, i.e. soap bubbles, even pipe dope, as well as my digital meters to include my truck GPS in a milk crate, and take them into the house at night to prevent my digital screens from freezing up. I'm worried that my testo digital screen will freeze making the gauges useless. Thanks.

[@JamesPettinato]

+Steve Wood I like the milk crate trick, the only time I've had a problem with my digitals was on a -8 degree real temp day, my amprobe and testos came on very slowly, but they did come on, thanks

[@fondamatassa2738]

Dear Jim, Thank you for your insightful videos. Here in Australia it is currently a wickedly hot summer (40°C days); watching your work in such cold conditions is so unlike life down under. God bless you for your fine presentations. :)

As a Canadian, I can relate to this video... I hate working on rooftop units when it’s cold. Great video Jim.

[@jimbola77]

alright jim alway's looking forward to your excellent video's!!!

You are hardcore Jim, even have a good attitude when it's freezing cold. Love your videos, keep them coming

[@theoldbigmoose]

"Do your work without grumbling and you will shine like the stars!" Great advice to this ol guy Jim. Your an inspiration!

[@whitesheatingairappliancer7101]

U R the man Jim, thank you.

[@JamesPettinato]

+Ron White thanks

[@heavydiesel]

Lots of stuff used to be wired like that here, you'd have one isolator for the power and if you were lucky, another one for the control circuit. I used to keep a metal clad double pole switch on the van, like you'd see for a domestic light, and wire that into the control circuit. Just meant you had to turn both switches off to work on the electrics. All my new stuff goes in on pumpdown so theres only one feed to the condensing unit and no control circuit fed from elsewhere to worry about. Nice work Jim!

[@JamesPettinato]

+heavydiesel I like that idea, might try it, thanks

[@kylefaubert7768]

where did you get that flat head screwdriver jim?

[@JamesPettinato]

+Kyle Faubertq Vaco makes yellow ones, I like them because they look happy, thanks

[@aircooledtx]

Ole school temp/ change in extreme cold. Great job, Jim..

[@rafaellarios3707]

Hi there Jim, Thanks for sharing your experiences with us. I have a couple of questions, though: 1. Do you always use that paste along with what looks like Teflon tape on all flare connections? 2. What are the dangers of Refrigerant cross contamination due to using (what looks like) the same gauges and hoses with all the refrigeration systems you service in the standard course of your business? Thanks again, I take my hat off just by seeing you servicing that system at such low temperatures.

[@JamesPettinato]

+Rafael Larios I use "leak lock" and teflon tape, There's absolutely no cross contamination from using gauges, thanks

[@20antman]

Hey Jim it looks like your suction accumulator is leaking refrigerant or possibly your suction line filter dryer is leaking. It looks dark in that area. I live in sunny south Florida. Wow that must suck working in that cold. I give you credit for that. Good video.

[@JamesPettinato]

+Anthony Reardon hvacr the system was full of gas, thanks

[@Kcarviper]

Ranco bro? You wanna be back Johnson control call it a day

[@JamesPettinato]

+Kcarviper Ranco/Johnson, thet're both good, been using Ranco a long time, back in the 60's they were in oarnge and black boxes, then in the 70's they went to yellow and black boxes, recently the boxes are blue and white, thanks

[@mikecummings2188]

what kind of Teflon tape did you use

[@cliftonnichols6170]

Jim is that your battery powered coat, my hands hurt from just watching, great work

[@BRReed86]

Hi Jim, I think you’re awesome! Always learn a lot from you. What is the average bill for a repair like that up there?

[@capitolrefrigerationheatin7501]

thanks for posting

[@petersmith5199]

Amazing video Jim. I can't imagine any refrigeration engineer going up on a roof to work in the snow, and with no safety rails either here in the UK. We have a "health and safety" rule book that just gets bigger and bigger! What a different work ethic you have over there!

[@JamesPettinato]

+peter smith what doesn't kill you makes you stronger, thanks

[@Terrible1]

fuck that. I wouldve jumped that high head switch and called it a day, see you in 3 months lol I can't work in those conditions. I have horrible blood circulation in my hands. It plagues me every winter.
