Why Fine Tune Equipment?
There are many reasons for fine tuning heating, air conditioning, and refrigeration equipment, such as energy conservation, cost effectiveness, less need for new power plants, improved performance, and equipment longevity. It is true it takes more time to fine tune equipment so that it operates at peak efficiency, and this comes at a greater cost to the customer. However, when the benefits are properly explained, most are willing to pay the service fee, which is usually saved many times over through the more efficient and economical operation of the equipment. Also, the technician who has the ability and desire to fine tune equipment can charge extra for his labor and will always be in demand by the public.
Because of the constantly decreasing sources of oil, every possible step must be made to conserve its use. Fine tuning heating, air conditioning, and refrigeration equipment is a very good place to start, because air conditioning units are the largest users of electricity in residential and many commercial buildings. When heating, air conditioning, and refrigeration units are operating at peak efficiency, this percentage of power consumption is reduced by sometimes as much as 25%. Several tests have proven that nine out of ten heating, air conditioning, and refrigeration units are operating at a reduced efficiency that is between 10% and 40% of their rating.
When heating, air conditioning, and refrigeration equipment is operating properly, less energy is used and the cost of operation is reduced. Thus, the customer is saving money. When the technician fine tunes the equipment so it operates more economically, the customer is more satisfied and is much more pleased with the service provided. The service technician can usually charge more for providing this fine tuning service, because the customer is more willing to pay for good, thorough service that ensures the equipment is operating as designed. Because of this, both parties are satisfied and the customer is more apt to recommend the technician to others who may want this type of service.
LESS NEED FOR NEW POWER PLANTS
When heating, air conditioning, and refrigeration equipment is working at peak efficiency, power generating plants can be operated at less than full capacity. The power company not only saves on operating expenses, but the need to build new power plants to furnish power to inefficiently operating equipment is no longer a consideration. Thus, the need for costly power plant construction and operation is eliminated.
Properly tuned heating, air conditioning, and refrigeration equipment performs better than equipment that is not properly adjusted. The customer will be more satisfied with the operation of fine tuned equipment. In addition, the unit will keep the building more comfortable, the process refrigeration and heating equipment will satisfy the demands much more easily, and there will be less service and maintenance required.
Fine tuned equipment has the proper amount of refrigerant and oil flowing through the system to maintain properly lubricated components at their desired operating temperatures. Properly lubricated equipment operating at the desired temperature usually lasts much longer than equipment that does not have these characteristics. Thus, the customer is saved the cost of having to replace the equipment, and major repairs are either eliminated or postponed to a much later date.
CHECKING PRESSURES, TEMPERATURES, AND AIRFLOW
A check of the operating refrigerant pressures and temperatures, along with determining the airflow through the unit and the temperature rise or drop of the air, is usually all that is needed to determine the efficiency of the unit. The proper adjustment of one or more of these operating factors usually determines the Btu output of the unit. Of course, the ductwork, insulation, and the condition of the structure will determine, to a great extent, whether or not the system will provide the desired conditions inside the building. All of these factors must be considered when fine tuning equipment to ensure more complete customer satisfaction. Remember, the best equipment will not perform if it is installed poorly. Installation is also a part of fine tuning a unit. The unit may be operating at peak efficiency, but if the conditioned air cannot reach the space or if it is not properly distributed, the result will still be poor operation. Give the installation a thorough inspection, and inform the customer of anything that can, or must, be done to obtain optimum efficiency and satisfaction.
