I recently had a minor complication with our air conditioning. Whenever it started up the cooling device would rattle for hours. Instead of calling for an air conditioning repair I ignored the unpleasant noise. I hoped it would simply go away on its own. Instead of fixing itself the performance of the air conditioning gradually worsened. It started running for much longer cycles and often screeched loudly. Since our beach house was still nice and cool I procrastinated scheduling service. Air conditioner repair is inconvenient and costly and I wanted to put it off as long as possible. I was reluctant to take a morning off from work and I’d been saving for a winter ski trip. Gradually, however, the air conditioning started to leak a lot of water and smelled weird. When our beach house began to feel sticky I simply lowered the thermostat by a few degrees. The air conditioning finally quit completely at three o’clock in the morning on a long weekend while in a heatwave. The outside temperature climbed into the triple digits that morning and the humidity was brutal. To avoid paying overtime charges I went without A/C until I could schedule an appointment while in proper corporation hours. I suffered the heat and humidity for nearly a week. The HVAC serviceman then told me that the malfunction had been caused by a buildup of dust within the system. Had I called for repair when I first noticed a problem the issue could have been resolved easily. I would not have needed a bunch of replacement parts or spent a small fortune on repair.
