How Preventive HVAC Maintenance = Savings

 
Preventive maintenance agreements (PMAs) are agreements between you and your quality HVAC contractor for scheduled inspections and maintenance of your heating, ventilation, and air conditioning (HVAC) system.

PMAs are generally scheduled semi-annually 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 PMAs are also referred to as “planned maintenance agreements,” “start and checks,” or “preventative service agreements.”  PMAs usually consist of fall and spring scheduled sessions for a service technician to go through your entire HVAC system preparing it for the upcoming season in a proactive approach before system failure andprior to overpaying your utility company.


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 1/3 rd of the energy used in the United States is used to heat and cool buildings.

According to the Consortium of 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,” according to Larry Taylor, President of Air Rite A/C Company, Inc., Fort Worth, Texas.

Out of Sight, NOT Out of Mind

The old but true cliché “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 you expect a quality 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.
