I was called to a home in Alaska to repair a broken air conditioner. The unit was a Gibson package unit, which is a type of central air conditioning system commonly used in homes and businesses. When I arrived at the house, I found that the unit was not cooling properly. I inspected the system and found that the compressor was not working properly. I replaced the compressor and tested the system to ensure that it was working correctly. I also checked the refrigerant levels and added more if necessary. Finally, I cleaned the unit and made sure that all the connections were tight. The customer was very pleased with the work I performed and thanked me for my help.
