10 Compelling Reasons Why You Need HVAC Preventative Maintenance

CES HVAC Preventative Maintenance FloridaProper maintenance of HVAC systems requires careful planning and forward thinking.  Organizations that have implemented comprehensive planned and predictive maintenance programs show dramatic decreases — as much as 35-45 percent — in overall maintenance costs.  

The primary goal of a HVAC PM program is to avoid or mitigate the consequences of equipment failure.  PM plans are designed to preserve and restore equipment reliability by replacing worn Original Equipment Manufacturer (OEM) components before they actually fail. 

Preventive maintenance activities include partial or complete overhauls at specified periods (monthly, quarterly, semi-annually and annually).  In addition, technicians can record equipment deterioration, which is the first step in planning for warn part repairs or replacement budgeting.

10 Compelling Reasons Why You Need HVAC Preventative Maintenance

  1. Better to schedule maintenance activities using planned and predictive maintenance tools then to operate in a reactive "break-fix" mode.
  2. The cost of HVAC system maintenance is very small in comparison to the potential costs related to poor IAQ issues and their related fallout.
  3. HVAC systems in typical commercial buildings are responsible for more than 40 percent of total energy use.
  4. Sometimes the difference between keeping a business running and having to shut down is nothing more than proper HVAC system maintenance.
  5. Reactive maintenance is the most costly way to maintain building HVAC systems; as much as 50 percent higher.
  6. Facilities in which proper HVAC maintenance is completed will use at least 15 to 20 percent less energy than those where systems are allowed to deteriorate.
  7. Improved HVAC system reliability
  8. Facility executives understand that without proper HVAC planned maintenance, the service life of HVAC systems and components will decrease.
  9. Break-fix maintenance repairs cost 3-9 times more than planned repairs, so maintenance plans that rely heavily on reactive maintenance are generally the most expensive.
  10. Safer HVAC equipment operation

What is preventative maintenance?

According to Wikipedia, preventive maintenance (PM) has the following definitions:

  1. The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection, detection and correction of incipient failures either before they occur or before they develop into major defects.
  2. Maintenance, including tests, measurements, adjustments and parts replacement, performed specifically to prevent faults from occurring.

ASHRAE Technical FAQ on HVAC Maintenance (pdf)

Does ASHRAE have recommendations for equipment maintenance procedures and maintenance frequency?

Yes. See the ASHRAE Standard 180-2012 – Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems, 2015 ASHRAE Handbook – HVAC Applications, Chapter A39 and ASHRAE Guideline 4-2008 (RA 2013), Preparation of Operating and Maintenance documentation for Building Systems. ASHRAE Standard
62.1-2016, Ventilation for Acceptable Indoor Air Quality, also includes a section on maintenance.
