As HIROC is your one-stop shop, we facilitate mitigating your risk of exposure to a variety of equipment, such as AC Units. Together with our partners at HSB, Subscribers have access to an inspection team that conducts inspections to prevent avoidable losses, ensure compliance with jurisdictional requirements, and aid business owners in safely operating equipment.

However, there are additional measures your team should take to enhance the operational stability of your equipment. Our advice below is intended to complement the equipment manufacturers.

Air Conditioning Units

A: Annually check

  • Open or hermetic motors for burn-out.
  • Air ventilation openings on open-type motors for obstruction.
  • Bearings on open-type motors for proper lubrication.
  • Motor windings using an insulation resistance meter. Motor shouldn't start if resistance is less than one megohm.

B: Annually inspect motor controls

  • Magnetic starters' covers to examine contacts for deterioration due to compressor cycling.
  • Terminal connections for tightness.
  • Overload protection for defects and proper sizing.
  • Mechanical linkage for binding and looseness.

C: Monthly checks for fans

  • Broken, cracked, bent, or loose blades and hubs.
  • Fan shaft and bearings.
  • Belt tension and condition.

Your partnership with HIROC and HSB means you have access to a team of inspectors to help identify and recommend ways to improve operation, maintenance, and reliability of your equipment. Our objective is to minimize losses, maintain functionality, and ultimately support life-saving operations.
