Below is an estimate for today’s service call and the renewal. System was not cooling. Found condensing unit completely void of refrigerant. Turn the breaker off at condensing units a unit does not try to continue to come on. Opened up air handler and inspected evaporator coil in primary pan and found evidence of oil in the primary pan on the left side. Quoted repair with customer. We are on schedule to return tomorrow to replace the evaporator coil under warranty. The only additional charge will be for refrigerant..
