HVAC refrigeration service and preventive maintenance

Preventive Maintenance  vs.  Reactive Maintenance

Preventive Maintenance

  • Preventing costly and otherwise avoidable repairs.
  • Equipment installed from the factory is intended to run optimally throughout its entire life.
  • Preventing costly failures starts with inspection and service
  • Trending equipment overtime starts with creating a service report
  • Evaluating HVAC equipment is much like understanding when your car needs a tune up
  • Operating conditions and evaluations assist in the service inspection by providing details of past and current performance.
  • A service record and details of each unit's operating history is key to determining if and when a component will require service.
  • Many times minor adjustments are neccesarry before costly replacement parts are added to a unit.

 

Reactive Maintenance = Destructive Maintenance

  • Reacting to breakdowns leads to higher repair costs
  • Large repairs can be prevented by regular maintenance
  • Addressing only the symptoms doesn't fix the problem
  • Leads to more symptoms & creates further component failure
  • Leaks dont fix themselves or disappear
  • An ounce of prevention is worth a pound of cure
  • Dirty coils lead to higher energy costs, and system failures
  • Improper inspection of electrical components can cause motor and component failure
  • Systems are most efficient when everything works like a system
  • A failed component in a blower assembly can cause blower failure, compressor failure
  • System downtime causes manufacturing to incur production losses

Preventive maintenance is an invaluable investment only worth the service you receive.  G&M ACR provides its clients with a tailor fit program specifically designed to appreciate over time and contributes towards renued revenue  in any facility.  Belts and filters account for only 2% of the service program G&M ACR offers.  Below is a list of typical services included on all equipment inspections.
