I knew that heating plus air conditioning professionals are only called when the unit shows signs of breakdown for the longest time…
Then this mindset changed when our overly conscious brother came to live with myself and others for a few months, but he was easily observant the first few mornings and kept most things to himself until he could not take it anymore.
The air was uncomfortable for him, especially when I went to work and left him to relax and do whatever he wanted. He told me and others that it was almost impossible to stay indoors when the sunshine was hot since the AC seemed not actually working! I rushed to inspect it, and to our surprise, everything seemed okay; so I did not understand why our brother was complaining. I took the next day to see for myself, and true to his claims, our unit seemed to be struggling to cool the space. There was easily little cool air getting into the house. I evaluated the outdoor unit, and it was not even blocked. I remember instructing someone to clear the bushes and debris around it a few weeks back, so it was perfect! Then next, I evaluated the filters, and they were pretty straightforward since I had swapped them more than one weeks ago; however, my brother recommended checking the air ducts, which I must disclose that I had not paid much attention to. She did the leak test and told myself and others that there was a significant air leak in our HVAC duct! His suggestion was to call another heating plus air conditioning expert to inspect and recommend the best fix for it. When the heating plus air conditioning specialist came over, he recommended cleaning a professional HVAC duct as the HVAC duct was clogged and cracked. It required thorough cleaning before it could be repaired.
