Yea,I’m the old man yelling at clouds. After 44 plus years of a/c service work,the bullshit I see in res and light commercial a/c pisses me off. We have useless regulations that most of the world doesn’t,because they don’t have a/c. I just spent most of summer either with windows open and ceiling fans going or a/c set on 80. I spend 8 to whatever hours being hot. Unless you live in mansion, the average home does not need variable speed blower,compressor and actuated dampers. Res contractors went from fixing,to parts changers and now salesman. And the more unnecessary bells and whistles (oh it will save u money on your power bill) is bullshit. When that go to hell controller / tstat fails,it cost what u supposedly saved. I see this constantly with vfds on chillers. When they take a shit,it’s about 50k to 75 k. There goes the savings.

The old saying around here is we make dollars not sense.
When I was on the construction side it was the 4Cs. Chaos Creates Constant Cashflow

The supply houses have lowered prices for pallets of refrigerant. At least around Atlanta. 22 price was below 1k for a pallet. Surely Witchen supply is doing this. Trane supply still doing it. And Bama Trane is run by Atlanta. I'm not sure. I don't deal with the HVAC stuff much any more over on my side. What ever everybody else is paying for ut we probably pay 3-5x more. Cause..."nuclear" Yep. At carrier we did panel replacement on a couple of tva nukes. After taking off cost of putting panels in nema 12 boxes and getting in and out of plant,cost was still double. And utc didn’t want to do because of liability since a nuke. |

Yeap simple for the average home is the way to go. Less shit to break as well. |

We use a lot of X washers in the breaker shop. There are Safety Related (SR) and non Safety related. They are literally the same washer. Come from the same factory. Out of the same machine. Have the same part number except one comes in bag that says 123xxx(SR)
and the other is just 123xxx. We probably pay pennies for the non SR and $40-50 for the SR ones 🙄

Question for those in the know. If the new refrigerant doesn’t have sweat fittings, will they make it adapters that you can connect your existing tubing or do you have to rerun all of your tubing?

I think about 10 years ago(I don’t have to use it)sporlan, refrigerant parts supplier,came out with zoom lock. Basically same as pro press that plumbers have had for 20 years. The word in our industry is replacement compressors and other parts will have copper extensions for pressing. There have been press fittings for a few years now. Or the coils and compressors will be roto lock, which has been around forever. Just use sparkless wrenches, which also been around forever. Damn glad I don’t do res and fixing to retire and may not double dip. I took a new apprentice to a supply house for decent free bbq. A lot of the suppliers there. All the tool venders had some form of pro press. Even Uniweld, the gold standard in hvac, for torch tools. The main guy was in 50’s, looked at kid and told him, you may barely ever braze. Unwield has a press tool. |

Also overseas, they came up with a gator bite fitting that works on refrigerant. It’s used over here.

I miss those old rooftops that didn’t have circuit boards. It seems like everything went to crap when they started with all the circuit boards 😞

I'm glad I know a guy that keeps my 45 yr old dinosaur geothermal humming happily. No circuit boards in it. I keep a spare pump on hand, and flush the water inlet monthly.

I tried a few different websites. Put a package in the cart. Gets to have to select coil position and Freon type and 410 not selectable. Dang. Interesting tidbit about my AC buddy. He did a lot of work around Atlanta area and restaurants. He used to grease the beak gears on Big Chicken KFC in Marietta Ga
