    10 years in the business and never seen this hack job

    Went to a new customers house today. They moved into the house a week ago. Called about the EAC making a zapping noise and fan not cycling off. EAC very dirty of course. That was the least of their problems. Went out side to check the heat pump. This is what I found. Reversing valve completely removed along with the accumulator. Compressor windings shorted and 10psi on the gauges. Did a leak check. Evap coil leaking and the TXV sensing bulb just dangling there. This is a 02 Carrier Puron system.
    Have any of you techs come across this mess before. I have no clue why someone would do this.

    was the serial number scratched off? i went to a brand new job that had carrier r-410a infinity a/c units. all of the controls were ripped out, LPS and HPS bypasses, some compressors replaced, and r-22 txvs.

    the a/c company was long gone

    We won the contract on a government job almost two years ago. The building is 6 years old now and the first contractor just about destroyed it. The building uses ClimateMaster heat pumps with water cooled condenser coils. Full contract job so any repairs are on the HVAC companies bill.

    Found 63 out of 155 units inop.

    Still adding up how many but currently I have found 89 safety devices removed.
    Found the biggest unit had the reversing valves removed, the circuit boards rewired. 3 relays added. They burnt up the wall sensor, the circuit board, and the controller board, removed ALL of the safety devices 2 HP 2 LP 4 freeze protection, and a condensate drain float.

    Found 12 replaced BACnet ALC controllers replaced with either just a Thermostat or a Distech LON controller. Of course none worked with the front end.

    Found a condenser water pump and boiler control system half replaced with 2 VFD's attached to a Distech controller while the other half being the water tower controls, water sensors, and ambient temp. sensors that the Allerton system needed, removed from the Allerton controller even though the controller was still in place and operable.

    13 busted Spoorlan power head TXV's

    Found 8 compressor burn outs and 2 units with a factor charge of 3lbs of R-22 charged with 22lbs of r-22. Guess what condition the compressors where in.

    4 freshair dehumidifier coils busted due to freeze.

    Finally, the HVAC company told the customer(A Veterans Home) that Climate Master was out of business so any repairs had to be done against OEM spec.

    All because the installation company forgot to flip one switch(one each unit) to delay the compressor startup 1 minute because the water actuator had a 45 sec delay on open which caused the condensing coil to freeze up when the system was in heat mode. And because they had no idea how to program the ALC controllers provided by Climate Master.

    It took them 5 years to destroy it and it has taken me 1 1/2 years to get 94%ish of it working again.

    Still gotta replace the safety devices dehumidifier coils, and redo all the pump and water tower controls.

    But the customer is extremely happy with us

    That's an easy one to answer, probabiy didn't need it any more!

    You need a few more years in the business, after near 30 years that mess is almost every day stuff.
    Just when i think I have seen it all I find something I never dreamed of.

    The rev.valve most likely quit actuating
    I have to admit i pulled one out this weekend myself. It was at a buddy's house and he didn't have have the money to buy a new valve at the present time. I gave him labor but i wasn't gonna buy the part. I saw no reason to pull the accumulator. His air handler has plenty or electric heat. Does this make me a hack?

    the bi.flow drier was coming apart and got trash in the capillaries that move the slide. also replaced the clogged drier, pulled and cleaned the evaporator, and even washed his blower wheel too..
    If its worth doing, it's worth doing right.

    So i assume the reversing valve failed because obviously you wouldn't remove it if it was operating in cooling since the electric heat works

    Id have convinced him to just throw down the money for the RV. I think when he opens up his electric bill this winter he would agree.
