Hello. My name is ***** ***** I'll do my best to help. Let's get started and see what we can do.PLease provide model on unit and explain what is happening.Where is the brass tubing you are referring to?
Customer: replied 1 year ago.
It is the small brass tubing that the refrigerant runs though to the coils im guessing. Dont have a model number I'm at work. Its a train heat pump. In ac mode everything runs fine but it puts out mild air and the tubing gets really hot
Expert:  airheatman replied 1 year ago.
OK the tubing is most likely copper if it is running between the units.Troubleshooting this will require some back and forth question and answers and possibly a set of refrigerant gauges a a volt meter. If you have or can obtain these tools,we should be able to diagnose what is going on.Without the gauges and meter, we will do a lot of guessing.Let me know and when you will be onsite to troubleshoot the unit.
