The summers in my local area are usually short.
We often have years when the whole summer is chilly and wet.
We sometimes don’t even bother to run the air conditioner. This past summer was one of the hottest on record. As early as the beginning of April, the outside temperature climbed into the eighties. By the end of May, we were getting temperatures into the low nineties with excessive humidity. The air conditioner struggled to keep up. Despite lowering the thermostat several times, the house felt slightly overheated and sticky. I also noticed an unpleasant odor wafting in the air and more dust than normal. I finally called an HVAC contractor to service the air conditioner. When he accessed the inner workings of the system, there was an alarming buildup of dust. There was also mold, bacteria and algae growing inside. The technician told me that the warm, moist environment inside the air conditioner is the perfect environment for microbial growth. When the air conditioner operates, those spores and harmful toxins can become airborne and introduced into the breathing air. Plus, the buildup of contaminants hinders airflow and causes discomfort, greater energy consumption and higher running costs. Fortunately, a thorough cleaning of the cooling system solved all of the problems. The technician then recommended that I enroll into a preventative maintenance plan. The plan includes two service calls per year to troubleshoot, clean and adjust the air conditioner and furnace. I get a discount on parts and labor for repairs, priority scheduling and no added fees for overtime service. The professional maintenance also fulfills the warranty requirements.
