Repair

 

HECO has the services you need to help repair motors and rotating equipment.

 

Our Philosophy and Approach

You’ll experience the difference with the first job when we ask you a variety of questions before we pick up the unit.

  • 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 unit starting is used?
  • Any special instructions?

Service Centers

HECO’s 60 years of experience in repairs are available in a wide area to serve you in the most efficient manner. See HECO’s extensive service area.
