How a HECO Repair is Different
The way we think is what makes us and our repairs different. You’ll experience it with the first job when we ask you a variety of questions, such as:
- Why are you removing the unit? Did it fail?
- What is the application for your unit?
- How long has the unit been in service?
- What type of starting is used?
- Are there any special instructions?
Using these questions as a means to uncover the “why” of any issue you are having, HECO then focuses on potential issues to make the right repair on the first service and prevent the need for recurring repairs.
