About a month ago we had problem with one of our heat pumps. It was blowing hot air. They replaced the thermostat (it was calling for emergency heat when it shouldn't), the compressor motor and a capacitor. Now it is not working correctly again. It doesn't seem to be blowing hot air, but it isn't cool. Sometimes the compressor is running but the fan on it is not running. On the air handler there are two copper tubes. Sometimes the larger one is cool (and wet), other times it is room temperature. The smaller copper tube is hot. Does this mean it is calling for emergency heat again? Or what could be the problem?
