Upon arrival found low volt fuse to be blown. Replaced fuse and immediately blew again. Disconnected loads and replaced fuse. Reconnected loads to determine the problem. Outdoor wires were blowing fuse. Turned off power to both units and started to diagnose outdoor unit. Found red wire shorted to ground. Narrowed short down to low pressure switch wires. Found both wires rubbed through. Removed condenser fan and repaired wires and secured. Jumped w1 and w2 together. Tested system and changed air filter. System running well at time of service.

Found that they mainly get the pipe shaking noise whenever they 2nd floor zone opens and nothing else is calling, this is caused by with the way this boiler operates is the pump runs all the time at the boiler and valves are shut and this creates a pipe shake. Before there was a zone valve that always let the water bypass to the second floor, we eliminated this beacause it was over heating the second floor this way. Zoning is working correctly at this point. Told homeowner the only way we could try to change this is by changing the boiler control which is not worth it beacause it operates fine.

Found 2002 trane heat pump completely frozen up. Also found unit had settled pretty bad, and top hood broken. Told homeowner at this point the unit would have to un thaw to determine if it Is a defrost issueor if system could be low on charge also. Told homeowner that it is not worth fixing at this point and heat pump should just be replaced. Set up appointment with bill to come out to give replacement quote.

12/6/2019 . Completed install 4 new zone valves. Traced out each individual circuits and transformer feeding the valves. Found that one valve anytime time there was a call for heat on any zone had sent heat directly to the 2nd floor loop. Changed it to 1valve feeding the second floor, and the labeled each loop. Anytime boiler is heated circulator pump will always energize when the boiler limit hits 140 degrees.
