We regret the trouble you have experienced with this air conditioner. This model has been designed as a Sealed System machine, meaning that it does not have a refill valve available. If this is not cooling properly, then the air conditioner may require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.
