First post here so go easy on me! I had my hvac guy install a ramsond split a/c system that came precharged. I think he installed it correctly becuase it is "low on pressure" as he puts it. Is that possible that it would come incorrectly charged from the factory? Should it be able to just be hooked up with the quick connect fittings and pressurized via the release valve that is on the brochure? Just trying to figure out if I'm getting taken for some extra cash.
Thanks in advance!
