for Waynesville, OH
1 yr old HP is making a load noise when it comes on . some air in the lines. I did find that homeowner soft soldered the refrigerant lines which is not the recommended way to connect refrigerant lines. This can allow flux to get into the system. I Explained to customer that due to the fact that we did not install the system, and the system does not appear to be installed properly, this is something we will not be able to work on.
