Preventative Maintenance Agreements = Savings

Preventative maintenance agreements (PMAs) are agreements between you and your quality contractor for scheduled inspections and maintenance of your heating, ventilation, and air conditioning (HVAC) system. PMAs are generally scheduled semi-anually to maintain peak efficiency, prevent utility overpayment , and avert system failures through predictive maintenance that can help extend the life of your HVAC system. Sometimes PCAs are also referred to as “planned maintenance agreements,” “start and checks,” or “preventative service agreements.” PMAs usually consist of fall and spring sessions for an service technician to go through your entire HVAC system preparing it for the upcoming season in a proactive approach before system failure and prior to overpaying your utility company.

Out of Sight, NOT Out of Mind

The old but true cliche “out of sight, out of mind” is often the reason for neglected maintenance guidelines for your HVAC system. HVAC systems are usually installed where they aren’t seen, such as in a section of the basement, a closet, on rooftops, or in mechanical rooms, making them easy to ignore. The systems are simply taken for granted, until they fail. Decreased efficiency, utility overpayment, discomfort, loss of productivity, eventual premature replacement, and higher repair costs are the result.

Just because your HVAC system is out of sight,does not mean it can be neglected. Getting your HVAC system checked twice annually is just as important as changing the oil in your car every 3,000 miles!

What should I expect my technician to do during a PMA visit?

  • Check system functions, safety controls, and adjust the operating sequence where appropriate.
  • Inspect electrical components and connections and replace/repair or tighten as required.
  • Ensure proper airflow and change dirty air filters.
  • Inspect pumps, lubricate, and check flow rates where appropriate.
  • Clean and lubricate motors as required. Examine belts,adjust and align as required. Inspect, clean and balance blowers as required.

What is the bottom line for me?

  • Savings: PMAs typically more than pay for themselves through higher efficiency, less utility overpayment, and contractor discounts. PMA customers typically receive a discount on all parts and services performed during the entire year.
  • Peace of Mind: Predictive maintenance will mean fewer system failures and longer life for your HVAC equipment.
  • Priority Service: Should a system failure occur during the heat of the summer or the cold of the winter, customers with PMAs generally receive priority service.
  • Continuity: Many contractors are often able to assign technicians to the specific customers. That way, you get to see and know the same service technician, and he or she becomes more familiar with you and your equipment.
