Why Consider a Preventive Maintenance Program?
The objective of a Preventive Maintenance program designed by Mountaineer Mechanical is to prevent functional failure. This objective can be accomplished
only by maintaining proper operations, by replacing necessary parts and by lubricating regularly. Faulty operation, failing
parts, or lack of lubrication can create equipment failure that will in turn, cause unscheduled loss of equipment, unscheduled
loss of production, or the unscheduled loss or use of an area in the facility. Many times these failures necessitate major
repairs and lead to expensive emergency service work.
A simple refrigerant pipe leak undetected for a short period can cause loss of refrigerant, equipment failure or even
compressor failure.
A simple loose wire
connection undetected can cause sparks, fire, blowing of fuses, or even at times premature equipment failure.
Studies show that Heating and Cooling units on retail
facilities run approximately 2000 hr/yr. This is equivalent of driving a car 60,000 miles per year. A Preventive Maintenance
program is basically like changing the oil in your car per the manufacturer’s recommendation.
Here are the facts:
1.
Preventive Maintenance helps you
and your air conditioning / heating systems.
2. Preventive
Maintenance is way of building maximum reliability into your systems.
3. Preventive Maintenance dramatically
reduces frequent service calls which are very costly and always inconvenient.
A too frequent example of how a quality PM Program could reduce both costs and
aggravation is a simple belt. Failure of belts averaged once a year. If you require service for a broken belt, it
will cost approximate $ 165.00 to fix it if the mechanic has the correct size. That same belt caught
and replaced during a PM inspection before it breaks may cost you only $ 17.50. And the cost due to aggravation is eliminated.
Other
major advantages to a Commercial Refrigeration Corporation Preventive Maintenance program are
as follows:
Studies shows that it also increases the efficiency of the system from about 3% to
14%, depending on the previous condition of the system.
Dirty air filters can reduce
the capacity of a system up to 12%. A preventive maintenance with filter service guarantees the filters are cleaned or changed.
During
preventive maintenance inspections, an air conditioning unit’s refrigerant pressure is checked. This procedure can
help warn if there is any leakage in the system. It is found that a loss in refrigerant reduces a system’s
efficiency by up to 60%. Moreover, unnoticed refrigerant loss can lead to very expensive compressor failures.
In
general preventive maintenance increases comfort, increase system capacity, lowers operating costs and insures longer equipment
life.
Some of the procedures MOUNTAINEER MECHANICAL could perform are:
Check the condenser coil for
its heat transfer and dust/dirt accumulation.
Check Fans and Blowers. Clean if required to insure
proper air delivery.
Check refrigerant pressures and assure the system is leak free.
Check the amperage of the compressors/motors.
Check exposed duct for any leak and proper
insulation.
Adjust belts and pulleys or replace if needed for better performance.
Check thermostat setting and calibrate if required to maintain proper temperature in the conditioned space.
Lubricate motors and bearings where possible to avoid frictional losses.
Test controls and
safeties switches.
Check the heating system for proper operation.
Check relays
and contactors.
Inspect the evaporator coil and clean if necessary.
Check and
inspect blower motor and its amps rating as compared to actual.
Preventive Maintenance is more than just a visual inspection. In Preventive Maintenance, a system
test is performed for proper operation so that defects can be detected before the failure of the equipment takes place.
