In the north, freezing temperatures bring about high demand for efficient, affordable heating systems. If a heating system fails, pipes can freeze and burst. It is critical to have your heating system in good working order. In the south, high levels of humidity can lead to mold and mildew problems. A house or businesses air conditioning system must running properly. Heating, ventilation, and air conditioning systems need routine maintenance by an HVAC technician.
This technician specializes in heating, ventilation, and air conditioning systems. His or her skill can repair and maintain a system to ensure it is working efficiently, properly, and affordably. HVAC technicians are trained to handle oil, natural gas, propane and kerosene heating systems. They also have a thorough knowledge of how the motors and fans run.
During winter months, HVAC technicians quickly diagnose issues with furnace/heating systems. They provide routine cleanings to prevent blockages that can lead to carbon monoxide poisoning. They also replace air filters, check for wear on thermocouples, test for gas leaks, check carbon monoxide levels, adjust flame levels, and ensure that the furnace is running efficiently.
In the summer, routine maintenance on heating systems can be completed. In addition, air conditioning and cooling systems are checked. Cooling systems must be examined to ensure the fans are running property, that no CFCs are being released into the environment, and that compressors and evaporators are working efficiently.
In new constructions, HVAC technicians install both heating and cooling systems. Pipes and ductwork are installed at proper locations for maximum heating and cooling abilities. Systems are tested for gas leaks, carbon monoxide issues, and fluid leaks. Motors are checked to ensure they are running properly. Then a final test is run to make sure the systems are heating or cooling the building properly.
HVAC technicians carry a wide array of tools. Beyond the typical tools of hammers, screwdrivers, and wrenches, HVAC technicians also keep pipe cutters, pipe benders, torches, voltage meters, carbon monoxide detectors, gas leak indicators, pressure gauges, thermometers, and more.
As HVAC technicians work in both outside and inside locations, warm, insulating clothing is necessary. New construction may be covered, but without a heating system in place, the unfinished building can be extremely cold. Working in tight quarters is always an issue, so an HVAC technician must be able to work in these extremes. Proper knowledge of first aid is necessary as breathing in dangerous fumes and the potential for electrical shock are serious considerations.
HVAC technicians possess strong math and reading skills. A good portion of their job relies on their ability to read blueprints and understand motor schematics. Most HVAC technicians are only offered jobs if they have completed an apprenticeship or a formal college-type education.
