Make sure they pressure test your lines for your ac, if you are installing new refrigerant. The older refrigerant requires less line pressure then the newer stuff. When congress first passed the law to change refrigerants and not allow the installation of the old style, they did not consider this and the newly mandated units were leaking at the pipe joints. They then modified the law to allow old style units to be installed in older buildings |
