Heating, ventilation and air conditioning, frequently referred to as HVAC, is often thought to simply regulate the operation of indoor heating and cooling systems. While consistently being too hot or too cold is a symptom of HVAC problems, more significant is the overall air quality and the resulting health risks. Producing skilled technicians with proper HVAC training, who are certified to diagnose and prevent health risks tied to poor air quality, is a process that relies on comprehensive HVAC courses like those offered at Spartan College.
Health risks relating to poor air quality can present as minor irritations or evolve into more serious diseases. According to the Environmental Protection Agency, symptoms of common ventilation-related health risks include irritation of the eyes, nose, throat, headaches, dizziness, and fatigue. Diseases like asthma may be triggered or worsened by poor air quality.
The EPA recommends three strategies to improve indoor air quality. The best, yet not always the easiest, is to eliminate the source of the pollutant – known as source control. Mechanical air cleaners are another method of improving indoor air quality but they are known to have varying degrees of effectiveness. The third and most common strategy to improve air quality is by making ventilation improvements – increasing the amount of exterior air coming inside.
HVAC training allows technicians to install whole house ventilation systems necessary to maintain indoor air quality with the maximum energy efficiency. The possible ventilations systems include: exhaust, supply, balanced and recovery. Exhaust systems are best for colder climates and are comparatively inexpensive. Supply systems, also inexpensive, minimize pollutants from the outdoors, filter pollen and dust, and are good for mixed climates. Balanced systems are appropriate for all climates, but are more expensive than supply and exhaust systems. And, finally, energy systems, can reduce heating and cooling costs and make the most sense in climates with extremes – hot summers and cold winters. Attending top quality HVAC programs will ensure technicians can work closely with property owners to select and install the HVAC system most appropriate for their situation.
Individuals working from home or in an office shouldn’t have to worry about the quality of the air they’re breathing and its impact on their health. HVAC technicians work behind the scenes to ensure the HVAC systems chosen are appropriate for the pollutants, climate, and budget of property owners. In addition, HVAC training programs will ensure technicians can diagnose systems requiring replacement or repair. HVAC technicians trained by Spartan College’s HVAC program improve the daily lives and working conditions of individuals everywhere after getting their HVAC degree.
