Last summer season, I was always sick & missed a ton of work. I suffered from extreme headaches, nausea, congestion, sore throat, & constant sneezing. Since I’ve never had trouble with dust sensitivities before, I couldn’t figure out what was causing my symptoms. I went to the dentist, tried prescription medicine, over-the-counter chances & even natural remedies. Nothing made a difference. I finally started feeling better when the weather changed. The cooler temperatures allowed me to open the windows & bring in some fresh air. That’s when I realized my a/c was the problem. I arranged an appointment with a local Heating & Air Conditioning professional, who took the system apart & found an spine-chilling buildup of contaminants. There was mold flourishing on the cooling coil, algae clogging the condensate drain, & dust obstructing airflow through the system, every time the a/c started up, bacteria & pollutants were spread throughout the home, & I was breathing them in. Along with degraded air quality, the accumulation within the inner certainly workings was causing higher energy costs & diminished comfort. The lack of airflow forced the a/c to run longer & job harder to meet control component settings, putting more wear & tear on components. I’m fortunate that the a/c didn’t suddenly malfunction & cost me a fortune in repairs. The professional cleaning didn’t take all that long & wasn’t overly expensive, yet made a large improvement in the cooling system’s performance. I signed up for a preventative repair plan with the Heating & Air Conditioning company, to avoid this type of concern in the future. The serviceman will return every Springtime to complete a full cleaning & tuning on the a/c.
