The hidden cost of deferred HVAC maintenance in commercial buildings
Introduction
When the HVAC maintenance is deferred, it might at the first glance seem like the short term expenses have also been reduced hence savings on the business’s finances. Yet this theory is far from the reality as the overarching expenses as the very consequence of the delay, turns out to be much more than expected, and in some the cases the overall budget also exceeds the one if the maintenance was done on time, this creates distorting hassle in the long term costs. Especially in the case of the commercial buildings where the expenses pertaining to the HVAC systems is known to be the most valuable operational asset, and therefore the neglect towards timely maintenance can give rise to severe inefficiency, failures in the equipment, risks with compliance and even the dissatisfaction of the tenant which inevitably impacts the overall business profitability.
Why HVAC systems are critical business assets
The wiseness is understanding that HVAC systems are so much more than simply heating and cooling systems, they support the comfort of the occupants, maintain the quality of air indoor, insures efficiency in the energy conception, makes sure of the operational continuity and even takes care of the overall value of the property.
Hidden cost #1: higher energy bills
Common causes
- Restrictions in the flow of air
- The heat transfer surfaces being dirty
- Inefficiencies in the refrigerants
- Fault in the sensors and even controls
Prevention strategies
- Replacement of the filters on a regular basis
- Cleaning of the coils as well as condensers
- Monitoring the consumption of energy
- Calibration of the controls done periodically
Hidden cost #2: unexpected equipment failures
Common causes
- Having the inspection being deferred
- Excessive wear over the components which are critical
- Lack in terms of lubrications
- Failures in the electrical connections
Prevention strategies
- Establishing proper schedules for preventive maintenance
- Performing routinely inspections of the equipment
- Lubrication of the components which are moving
- Conducting analysis over vibration
Hidden cost #3: tenant complaints and occupant dissatisfaction
Common causes
- Uneven distribution of the temperature
- The ventilation being inadequate
- Excessive humidity issues
- Inconsistency on the operations of HVAC systems
Prevention strategies
- Performing comfort assessments on a regular basis
- Air distribution systems which are balanced in nature
- Having proper maintenance of the ventilation equipment
- Quick responses to the complaints of occupants
Hidden cost #4: reduced equipment lifespan
Common causes
- Continuity of the operations under strain
- The system components being dirty
- Inadequacy in the lubrication practices
- Excessiveness of cycles
- Conducting the operations outsides parameters
Prevention strategies
- Following the recommendations of manufacturer
- Having the equipment cleaned on a regular time frame
- Making sure that even the minor issues addressed almost immediately
Hidden cost #5: business disruption and downtime
Common causes
- Critical failure of the equipment
- The lack in back up systems
- Maintenance activities getting deferred repeatedly
- Damage in the mission critical HVAC components
Prevention strategies
- Identification of the critical assets of the HVAC system
- Maximized utilization of the preventive maintenance technologies
- Development of the contingency plans and strategies
- Having the health of the system and its components monitored continuously
Hidden cost #6: indoor air quality problems
Common causes
- The filters being dirty
- Clogging in the air ducts
- Growth of mold and even microbials
- Close to no adequate fresh air intake
Prevention strategies
- Getting the filters replaced
- Monitoring the levels of humidity
- Inspection of the ventilation systems
- Maintenance of proper ventilation rates even outdoors
Hidden cost #7: compliance and regulatory risks
Common causes
- Frequently missing of the scheduled maintenance
- Failure to meet the standards set by ASHRAE
- The performance of ventilation not being up to the mark
- Violations of the refrigerant management
Prevention strategies
- Maintaining the records for maintenance in a detailed manner
- Following the requirements as per OSHA and ASHRAE
- Having the facility personnel trained over the requirements pertaining to compliance
Hidden cost #8: rising total cost of ownership (TCO)
Common causes
- Accumulation of the maintenance backlog
- Increment in the consumption of energy
- Reduction of the operational efficiency
- Higher expenses with pertinence to compliance
Prevention strategies
- Implementation of an in-depth and comprehensive program for preventive maintenance
- Maximizing the utilization of the continuity in HVAC monitoring
- Development of the long term replacement planning
- Conducting the system performance reviews on a regular basis
The ROI of preventive
| Preventive Maintenance | Deferred Maintenance |
| Lowered costs of operating | Higher expenses of energy |
| Repairs being planned | Hassle of emergency repairs |
| Extended life of equipment | Premature replacement |
| Increment in reliability | Increased downtime |
Warning signs your building may be suffering from deferred maintenance
- Rise in the utility bills
- Increment in the frequency of the service calls
- Repeated complaints over the occupant discomfort
- Excessiveness in the bizarre equipment sounds
- Deteriorating overarching HVAC performance
How a preventive HVAC maintenance program reduces risk
- Routine inspections
- Performance monitoring
- Maintenance documentation
Why leading commercial property owners prioritize HVAC maintenance
The most integral reason for prioritization of the HVAC maintenance as viewing it not simply as an operational expenses, but rather a financial strategy. When considered a strategic investment, businesses understands it impacts truly, which involves the prevention of the unnecessary operating costs, protecting the value of the asset, and even the increment of the long term performance of building.
Conclusion
One of the most expensive problems in the realm of HVAC are also often the ones which have high potential to be prevented. And deferring the maintenance of the systems belongs in one of the problems which can very much be prevented. By the adoption of the maintenance strategy which is proactive in nature, the owners of the commercial property can enjoy the benefits of risk reduction, increment in terms of reliability, as well as the maximization of the long term HVAC infrastructural value creation.
