Air conditioning is something the average homeowner cannot repair themselves. You must have an air conditioning license to purchase some materials. For example, freon is only sold to Arlington HVAC technicians with certification in air conditioning. If you have an air conditioning maintenance agreement, you can call the company that is familiar with your system to handle repairs. If the air conditioning unit is under warranty, the manufacturer will require a professional to handle any repairs. Once again, you can have someone who has serviced your system handle this.
