My cooling system quit while the people I was with and I were in the middle of a August heatwave. The outside temperature was steadily in the low nineties with excessive humidity. The cooling system was running just about non stop and struggling to keep up with demand. I should have called for repairs at least a month earlier. I’d noticed that the cooling proposal was making some weird sounds and running for longer cycles. It was spreading dust and a musty smell throughout the house… Despite lowering the temperature control setting by a couple of degrees, the beach house felt slightly warm and sticky. I waited until the cooling system failed completely and refused to start back up before scheduling service. When the Heating and Air Conditioning company removed the outer lodgeet, he showed me the accumulation of debris within the equipment. He pointed out the mold thriving on the cooling coils, algae growing in the condensate drain and layer of dust covering every component. He said that this buildup made it hard for moving parts to operate, restricted air flow and forced the proposal to run longer and work harder. Every time the cooling system started up, it was most likely introducing harmful contaminants in the breathing air. It was also using more energy, costing more to operate and suffering extra wear and tear. The repair was fancy. The worker needed to replace multiple parts and perform a thorough cleaning! Because of the overtime fees, the repair was nearly more than the cost of a whole modern cooling system, then from now on, I will schedule proactive service in the Springtime. Regular repair is cost-effective, helping to optimize energy efficiency, airflow, reliability and proposal longevity.
