Business ProfileforDaves Diversified Services Inc

We purchased two ****** heat pump systems through Lowe's in Oct 2018 and had them installed by Dave's Diversified Service (DDS), the contracted installer for ******. During installation they took the rocks we had used to keep the old units level and installed both units on them. Less than one month after the installation we had enough issues that DDS decided to replace the outside unit for the downstairs system Nov 17, 2018. We continued to have various issues that required service calls and adjustments to the system. Then June 6, 2019, DDS discovered our main unit had a leaking evaporator coil and they ordered a replacement coil. The new coil was installed June 12 2019. About a month ago we discovered the outside fan on the main unit would not shut off even when we turned the system off at the thermostat. We had to throw the breaker to make the fan stop running. We contacted our local company and they have been working on replacing the parts that were causing the issue. During the troubleshooting we were told that we had an issue with the evaporator coil (that was replaced by DDS), and they believed it was the wrong replacement part for our unit. They contacted Lennox to confirm their suspicions and found out we have the incorrect part. From what we understand Dave himself serviced the unit and most likely realized they had the wrong coil in the unit because he adjusted the amount of coolant down to a lower pressure because this was an undersized coil. DDS apparently failed to properly service the system for us and even though parts are likely covered under warranty, their negligence is going to cost us a fair amount of money for the labor as well as the inconvenience of the amount of time our units has been malfunctioning.
