Air Conditioner Thermostats

A thermostat is an apparatus for maintaining the temperature of a system within a particular range by directly or indirectly controlling the flow of heat energy into or out of the system. All air conditioners have thermostats that can be manually operated or automatically preprogrammed to work at regulating the room temperature. There are many ways in which you can use an air conditioner thermostat effectively.

One of the most successful yet economical ways to reduce your air conditioning costs is to adjust the thermostat setting on the air conditioner. The savings are more noteworthy when you set your thermostat at 78 degrees Fahrenheit or higher. For each degree you raise the thermostat setting, you reduce seasonal cooling costs by 7 percent to 10 percent. In doing so, you can use ceiling fans in addition to the air conditioner and thus, save a lot of money.

Most centrally located air conditioner thermostats are equipped with two fan settings, 'on' and 'auto'. When the thermostat setting is set to 'on' the fan runs constantly and when it is set to 'auto' the fan runs only during cooling cycles when the air conditioner compressor is in use. When the air conditioner is in use all day, the cooling compressor only operates about 50 percent of the time, that is, for about 12 hours. The extra fan operating time that occurs when the thermostat is set to 'on' can add roughly $25 to monthly air conditioning bills. Using the 'auto' setting, alternatively, saves energy and money because the fan operates fewer hours. Besides achieving energy and cost savings, the 'auto' setting also promotes more comfort by offering better humidity control as moisture removed during the cooling cycle is re-circulated back into the home while the compressor is off.

Thus, thermostats play an important role in the cost and function of an AC.

Diploma and certificate programs can be completed in a year or 18 months; AAS degree programs can be completed in two years and involve more in-depth study of management and business applications.

Training will include commercial heating, refrigeration and air conditioning, wiring techniques, service call procedures, and troubleshooting training programs and courses. Graduates of HVAC Schools are prepared for positions working with heating, refrigeration, and air conditioning systems as entry-level technicians, mechanics, and service sales persons.

Some HVAC Schools offer two-year Associate of Applied Science degree programs in service management. Students in AAS service management degree program will concentrate on business operations - accounting, business law, salesmanship, and management - and aspects of customer service. AAS service management graduates are prepared for positions as repair technicians, apprentice mechanics, supervisors, and managers at the entry-level.

HVAC technicians may work in various types of businesses and manufacturing, for private contractors, or in institutional buildings. There is a steady demand for skilled HVAC technicians. Even though the work can be strenuous at times, the rewards can be worth it, with most technicians bringing home respectible salaries.
