Business ProfileforPBCI - Allen Mechanical & Electrical

We called PBCI-Allen a week ago to fix a water leaking problem they left about 2.5 years ago. At that time, they claimed that the water pipes needed to be replaced and we did pay them ~$7500 for the work. A week ago, we had water leaking in the front yard, we requested the company to come back and check the issue but they refused to fix it without paying another few thousand dollars upfront. Another company did fix the issue for us, it turned out that PBCI-Allen did not replace the old valve when they replaced the old water pipes 2.5 years ago, apparently the valve was not in a good shape at that time - there is an hole. Work number: *********. Another work that PBCI-Allen did for us about two months ago is for our Heat Pump/AC unit, they claimed that we needed a new motor. We paid ~$700 for the new motor, but it did not solve the problem. It turned out that it was because the coolant level was low, once it was brought up the problem was fixed. We are looking for a refund for the motor ($700, they also took away our old one that was still functioning), and partial refund $ (2500) for the water pipes work they did for us 2.5 years ago since it was not complete - the valve should be replaced at that time, we have to pay a few thousands dollars to excavate the yard to replace the valve this time. Thanks!
