new ac unit question
When you buy a new house AC unit (Carrier, Trane, etc) does the unit come
with the Freon already pressurized in the unit...or does the installer add the Freon after everything is set. Also...in an older unit...can you rent a recovery tank and valve setup to save the old Freon that's in the unit...or again..does an ac installer guy have to do this ? thanks, Tim R |

The only losses are what escapes when the refrigerant lines are reconnected. This loss must be made up. Refrigerant recovery, I think requires a license in each state. That is, you have to take a course and pass to get a certificate that makes you a licensed refrigerant recovery person. So no, IMO, you cannot rent a refrigerant recovery cart without a license to operate it. |

new ac unit question
There is no loss when the lines are made up.....jesus
Yes, they come precharged...precharged for that particular condenser...a matching evaporator and a manufacturer specified amount of tubing between the two units. Some manufactures add enough for 15 foot of tubing some for 25....this charge still may need to be added to because of increased tubing length etc.... and it still must be checked and adjusted by a competant person because the factory charge may not be correct..especially if charged at the factory by a fat lazy american with no work ethic.... also checking the charge will also show any problems with the system itself....too little airflow, kinked tubing.... You need a professional to check out the equipment...too much or too little gas both can result in increased compressor wear. refrigerant recovery..... look for the access ports on the outside unit...take a valve core remover...like you would use for a car or bicycle valve stem and loosen the core to where you hear a steady hissing......come back the next morning and push in on the stem....if it hisses just a little bit just remove the corer completely..do this on the big line to minimize the release of tell tale liquid refrigerant. If you are going to attempt this yourself...good luck...you have not mentioned proper brazing techniques, leak testing...evacuation..... and they call me corny................ ~: |

The new unit comes with enough freon for up to 15 foot line set, or
maybe 25 feet. You need a license from the Federal government to add or remove freon from any appliance or device. For whatever reason, some auto parts stores sell R-134a, which must not be considered a controlled refrigerant, then? -- Christopher A. Young You can't shout down a troll. You have to starve them. ..

The license can be obtained on-line by passing a simple test: Can you stand up, hear thunder, and see lightning? Fill in your name and print your certificate. |

Bet you're right. How about I take a bunch of pictures, and we'll mail
them in and find out? -- Christopher A. Young You can't shout down a troll. You have to starve them. .. "CJT" wrote in message ...
