Im a homeowner who has a company installing stucco around entire house. While nailing wire lath up, they put hole into tubbing and the R-22 leaked out!!! My A/C guy came over and put a dye stick in and is waiting for me to demo inside of wall so he can use ultra violet light to track down leak..He also used a freon sensor and picked up area where it could be leaking...How would any of the great pros out there fix/find leak...Any help would be greatly appreciated!!!!THANK YOU!!!!
