Work Performed: Inspected 2011 Ruud air conditioner and found the system nearly empty of refrigerant. Also assessed piping from the water coil to the boiler. Results: Due to the age of the system and low refrigerant level, repairs are not recommended. The unit is not worth the cost to fix. Recommendation: Quoted for replacement of the air conditioning system, and a quote will be sent to replace the piping from the water coil to the boiler.
