This furnace is so old

Because of the hot and humid weather in the area where I live, central air conditioning is absolutely necessary.  Every business and home is equipped with some type of cooling system, and the equipment carries a heavy workload. I typically start up my air conditioner in February, and it runs non stop until early November.  If the weather turns a bit cooler, I sometimes only run the fan to circulate the air in the house. The continual operation of the air conditioner leads to very high monthly electric bills. There’s also concerns with air quality.  With the windows shut tight, there’s no influx of fresh outdoor air. My family breathes the air supplied by the cooling system. Unfortunately, the inner workings of the air conditioner are moist and damp, creating the perfect habitat for mold, mildew and bacteria.  If the equipment becomes overrun with contaminants, harmful spores and allergens are spread through the house every time it operates. Dirty air conditioners have been linked to a wide range of health issues, including asthma, allergies, respiratory infection and flu-like symptoms.  An accumulation of debris within the cooling system also restricts airflow. If the unit is supplying less air, it needs to run longer and work harder to meet the demands of the thermostat. Extended running times add up to greater energy use and higher expense. To resolve all of these problems, I’ve invested into a maintenance program with a local HVAC contractor.  They send a technician to the house every year, who performs a thorough cleaning, tuning and adjustment of all components. He keeps the air conditioner working at peak capacity and efficiency.
