Last year, right when the weather started to moderate up, I began feeling sick. Every day, I’d wake up with a headache and congestion. There were days when I was forced to call in sick to work. Since I don’t suffer dust sensitivities, I wasn’t sure what was causing it. I eventually noticed that our symptoms disappeared after I arrived at work. Once I arrived home, the stuffy nose, coughing, sneezing and sore throat would come back. I got suspicious that our was the cause. My health issues appeared at around the same time I lowered the thermostat. I called a local Heating and A/C supplier and busy a maintenance call. When the supplier took the apart, she showed myself and others the accumulation of contaminants within the inner workings. I was shocked by the amount of dust, debris, aglae and grime on the components. There was a significant amount of mold growth. The supplier explained that the hot, moist interior of the is the perfect environment for bacteria and other harmful microorganisms to thrive. Every time the cooling system started it up, it was spreading allergens throughout the house, and I was breathing them in. Plus, the debris restricts airflow through the system, forcing the to run longer, work harder and use more energy. I was playing higher than necessary weekly electric bills for diminished comfort. The greater wear and tear on the increased the risk of malfunction. After the supplier completed a thorough cleaning of all components, our health complaints went away completely. I now make sure to have our cooling system professionally took care of every Springtime.
