Preventive Maintenance
Preventive Maintenance = $avings! Take care of your HVAC system, and it will take care of
you. Preventive maintenance agreements (PMAs) are agreements between you and your Air Conditioning Contractors of
America (ACCA) quality contractor for scheduled inspections and maintenance of your heating, ventilation, and air conditioning
(HVAC) system.
PMAs are generally scheduled for the spring and fall to maintain peak efficiency, help keep utility
bills lower, extend the life of your HVAC system, and avert failures. Sometimes PMAs are referred to as “planned maintenance
agreements,” “start and checks,” or “preventive service agreements.” Most agreements offered
by ACCA contractors cover an inspection of the entire HVAC system and routine maintenance (such as replacing or cleaning filters).
Energy Consumption The HVAC system is most likely the single biggest use of energy in your
home. In commercial applications where refrigeration is applied (combined with the HVAC systems), huge amounts of energy are
used in the building. In fact, over a third of the energy used in the United States is used to heat and cool buildings.
According to the Consortium for Energy Efficiency (CEE), up to 50% more energy can be saved with proper installation,
sizing, and maintenance of commercial central air conditioning and heat pumps. Although the CEE study did not measure residential
systems, a compelling case can be made that proper maintenance can save homeowners up to 50% as well.
Out
of Sight, NOT Out of Mind The cliché “out of sight, out of mind” is often the reason for
neglected maintenance on 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, premature replacement,
and higher repair costs are the result. Getting your HVAC system checked twice annually is just as important
as changing the oil in your car every 3,000 miles!
What should you expect your ACCA member service 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 repair/replace 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’s your bottom line? Savings:
PMAs typically more than pay for themselves through higher efficiency, lower utility bills, 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 a 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 ACCA contractors assign technicians
to 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. © Air Conditioning Contractors of America Association, Inc., www.acca.org. Reprinted with permission.
