Hey guys I hate ordering expensive stuff from Amazon because they always ship it wrong!! I bought this vacuum pump because it cheaper on Amazon and fast shipping..

It came here when the box on its side, when I opened it up oil were covering the pump and bag... My question is, Should i clean it let it sit, fill oil and use it Or just return it and get one what was stored and shipped right

Thanks !

Today I got two phone calls and made interviews for this Tuesday. One is for hvac apprentice And the other is a refrigeration apprentice, Which one do you think is better in your honest opinion?

Fuck you Carrier.

The 3 door freezer on the left has condensation issues. Only on the outside of the glass doors. The 2 door freezer on the right never sweats. When the AC in the store is blowing cold onto the door it dries up most of it. Could it be the door gaskets are bad or possibly the glass window seals are bad? Looking at the gaskets they don’t look to be in bad condition.

Looking for ballpark estimates on what one of these should cost. list price. 10 - 15 k usd or maybe 20 , 25k usd?

Anyone have recommendations for high iron water filters? Also wondering how everyone goes about cleaning the grid. This is the build up after only 1 year

Bad condenser fan, wiring burnt up.

Edit: I have no previous experience other than a 2 week hvac class I took to get my epa universal.

I’ve been doing this trade for almost 6 months. For the first 2 I was riding around with another tech, then they put me in my own van. Currently I work in a lot of different commercial kitchen settings, mostly doing PM’s and some service calls on mostly cooking equipment. I’ve gone on a few refrigeration calls and only needed another tech on one of them. I’m not enjoying this service work as much as I thought I would, and I make less than I did working as a manager in a restaurant. I think I would much rather work in a super market setting, either building the racks or servicing them. Here’s the gig, I would get paid the same $ amount as I get currently, plus $60 a day per diem, plus 150 a week to use my personal car instead of being provided a company van. I would be traveling away from home for weeks at a time, gas and hotels would be paid for. The shifts are either from 6am-7pm or 8pm-7am, with only a 30min lunch, which I think would suck to get used to. What do y’all think I should do, I’ve been debating this for almost a week, but have no idea what to do. Should I stick out where I’m at, and see if eventually I make more money? Or should I take the new gig where I know the career advancement is high, in 5 years I could be making 35-45p/h. Thanks for the advice in advance!!

Head pressure vacuum

Five years from resi hvac and some resi electrical. Two months into market refrigeration. I’ve noticed that the amount of electrical component diagnosing is way less and am scared to get rusty on my electrical diagnostic skills I worked so hard to get

Today on my way to home from work. I decided to quit this trade.

2nd year apprentice here from alberta. I tried my very best to get into a refrigeration company, I switched companies but still no luck to learn refrigeration. For the past two years I have been installing residential AC thats it.

Why can’t companies just teach apprentice about this trade? why is it so hard to get into commercial company? Just heartbroken today. I loved this trade but no leads are getting me all frustrated.

Thanks yall

Have any of you had issues with 290 actually leaving the can and going in to the system. Today I tried weighing in the 4.7 Oz charge. Only got .5 of an ounce out. I thought the Schrader may have been the issue, so I used my core remover. Still had same issue. Going back in the morning to see whats going on. I'm worried I ran too much solder into the spun drier and that it could simply just be blocked. Your thoughts ?

One of the unintentional side effects of building cellars underground was that wines and beers often became cold relative to the outside temperature and in turn people prefer to keep alcoholic beverages in cellars because of this. So they acted as primitive semi-refrigerators.

I do ask though were foods meant to be eaten as cool such as deserts like chocolate and cold cuts ever kept in cellar in primitive times to keep them in an ideal state? I mean even with the lack of refrigerators I'd assume they'd already discover recipes where say certain methods of cooking sausages that were tastier chilled as the result of the existence of cellars since the time of ancient Rome or even earlier?

I was at a Costco today pulling some coils for a remodel. After we dropped them, we had some time to kill, and spent it playing with the micro thermo.

One thing that stood out, was a 68% receiver level. Looking through the logs, it was 67% before we pumped down 3 25k btu coils. Was hitting 98% during defrost, cold gas.

Split rack with more medium temp load than low temp.

68 degree ambient, and the condenser wasn't in split and heat reclaim active.

Doesn't this seem kinda high?
