When a 2024 customer's AC motor was running erratically, Derek checked the entire system and indicated that it was most likely the ECM motor control. That customer, who wrote that they are somewhat handy, said Derek suggested buying the part online and having it ready, and also suggested a capacitor because theirs was 12 years old. The same 2024 customer wrote that when the motor stopped, they replaced the motor control themselves and the motor started to hum again. A 2025 customer said they had used DV's Mechanical for a few years, with Derek doing their spring and winter PMs and fixing and advising on issues with the A/C or heat. A 2025 customer said Derek was professional, punctual and knowledgeable, and that the work was done efficiently. A 2025 customer wrote that a difficult job was explained with patience for all of their questions, and that they got help coming up with a plan that worked with their budget. On Google, DV's Mechanical has 5 stars from 38 ratings, and its BBB grade is A+.
