There was even algae growing in the condensate drain
Living in Largo, FL, the a/c is a priority plus a necessity. I run the cooling system nearly all year round, plus it officially handles temperatures in the high nineties or even triple digits. I spent quite a bit of currency for a high-efficiency, Energy Star rated a/c for my home. When I first started up the cooling unit last year, I noticed that it was making some unusual noises. I hoped that it would work out any issues after it ran for a while. Instead, the issues grew steadily worse. There was a musty odor coming from the vents plus a significant amount of dust plus other contaminants circulating in our breathing air. The cooling system seemed to be supplying less cool air than normal, but despite lowering the thermostat numerous times, the condo felt slightly overheated plus sticky. The a/c ran just about non stop plus the cost of my bi-weekly energy bill was an actually unpleasant surprise. When I finally tied up professional repair, the workers opened up the a/c plus showed me the problem. There was a great deal of dust, lint, mold growth plus all sorts of debris clogging the inner workings. There was even algae growing in the condensate drain. This buildup was restricting airflow, hindering performance plus forced the cooling system to work harder, use more energy plus cycle longer, not only was the cooling system putting out less cool air, there was also the risk of polluted indoor air quality; Fortunately, a thorough cleaning plus tuning fixed the numerous issues with operation. I have now enrolled into a repair program for the a/c.
