The following lines were added (+) and removed (-):
The suction line should feel cool or mildly cold, but not overly icy cold. If the suction line is below freezing (32F) or not within the correct temperature tolerance range for the specific unit, this indicates low pressure in the line.The suction line should feel cool or mildly cold, but not overly icy cold. If the suction line is below freezing (32F) or not within the correct temperature tolerance range for the specific unit, this indicates low pressure in the line. Some technicians say that this line should feel as cold as a soda can right out of the refrigerator (or some say beer can cold).The temperature and pressure of these lines during operation are impacted by the indoor and outdoor temperature. If it is not very warm outside, these lines cannot be accurately checked. Also, it is best to check the lines near the outdoor compressor.The liquid line leaving the condenser will never be lower than the outdoor temperature unless there is a restriction in the coil or the metering device is mounted in the outdoor unit.The liquid line should feel warm, approximately 100F. * Too hot - system may be undercharged (low on coolant)* Too cool - system may be overcharged (too much coolant)
