R22 home AC unit?
So our AC was failing to keep up with 95+ heat.
AC guy came and said R-22 was about 5-6 lbs low. Options: 1) put in "obsolete" no longer made $100/lb R-22 2) change out coil and do other upgrades to make system compatible with new refrigerant (whatever it's called) 3) replace unit 5 ton that was $8.4K lasy year, now $10 What say the brilliant minds of the BARN? |

I guess the 5 ton is the largest residential unit. Just hoping to patch it along till prices come down. |

Mine was just repaired last week, it's 34 years old. A wire on the condenser shorted out on the frame and knocked out a low voltage transformer in the furnace.
One common issue is the capacitor. I've replaced mine once. Way back when I was working for a service contractor we had a client who had switched from company A to company B. Company A had told them refrigerant, AKA Gas, needed to be refilled periodically because, you know, gas. Central Air units need to be sized properly. Putting in the biggest one you can purchase isn't necessarily correct. It'll cool the house down but you're left with a damp clammy feeling in the space. |

Kinda on the old side for your unit right? Run dye they can find the leak. Fix and add fluid=up and running quicker.
New unit big bucks, but if you are staying or keeping your place. You get x amount of years on the new stuff. Been there done that I decided to replace at that time. I did not know a couple years later I would have to give up my house. |

$600.00 in freon every 4 years is better than a new $10k unit that will also need freon in a few years.
I'll add that the newer units don't cool as well as R22. |

Find leak and refill at the moment.
Greed is rampant in any of the building industry at the moment. Some prices are justified due to short supply, but a lot of folks are just taking advantage of the CV-19 to line their pockets. Problem is, I have no idea when this will be "over". .gov is continuing to flood the money supply and this makes it ripe for the picking. The ONLY thing I have not seen a significant price increase on is liquor. Go figure... Best of luck |

You should never need to recharge your AC unit. If you do, you've got a leak that needs to be repaired.

I have reached a point where I don't even have to call an AC guy. I have saved THOUSANDS of dollars by owning the tools and learning. Repair guys are just human. If they can know how, I can know how. |

Years ago we demo'd a huge grocery store with a dozen compressors in an equipment room. Removing the refrigerant want like this; Put blade in sawzall, start hacking away until the oil mist drive you out of the room. |

I could misunderstand, but they said since in OK our duct work is in the concrete foundation, finding a leak can be nearly impossible?
The guy made it sound like R22 is no longer made and basically when the current supple is gone, it's gone, they do not manufacture it anymore. Also said that the new stuff does not cool as well as the R22 but since they can't get it...... |

I doubt the ductwork is in the concrete foundation, and even if they are the refrigerant lines aren't in the ductwork anyway. Find a new guy that knows what he's talking about.

Like I said, I may have misunderstood, but we did have to reroute the hoses under a concrete patio when we had the inground pool put in. Maybe that is what he was referencing.
