My sibling, Kelsey, & I are opposites; Kelsie can not touch oil or anything that is not the steering wheel, pedal, or car seat, even with a ten-foot pole, unless her life depends on it, and on the other hand, I prefer toiling on cars & motorbikes to the point I even work part-time in a car service shop, then there was a time Kelsey moved into my home because she claimed there was a rat in her cooling system.
The cooling system worker assured her that the cooling system installation had a mechanical issue, which is why it produced a odd noise! It still did set her at ease, however she went ahead & called a peculiar a/c business.
The new a/c supplier asked what the problem was since she had called, saying she needed cooling system repair… Now that she realized that the noise had indeed stopped, she told him that the Heating & Air Conditioning plan required cooling system service & cooling system care. The cooling system representative did as asked, but when he finished, he said that it had been a long time since he came across such a clean system, even though the filter looked new… He assured her that her component did not need a/c service. It could have gone another many or so months without implementing the cooling system care plan, & even her air quality would not have been affected in any way. The most she ever does when it comes to her Heating & Air Conditioning component is adjust settings on her control unit, which she does use her phone. She leaves the rest for the a/c business. If she needs to get something from an a/c supplier, she either does it via a phone call or picks a afternoon I am available so I can take her.
