They never messed around with the cooling unit before

My family grew up in a very quiet suburb where the community was pretty tight. I had the same friends from kindergarten all the way until middle university. Every one of us all began to drift to other cliques and circles in high university after hitting puberty; Dad was an accountant and mom a defense lawyer, which meant both of us had a truly wonderful life. Every one of us went on 2 or 3 holidays each year and had all the toys and gadgets both of us wanted. My dad was quite handy with fixing stuff around the new home despite being a professional. He’d grown up on a farm where they had to repair a ton of things themselves. So that meant both of us rarely had any techs like carpenters or plumbers coming to sort out things at home. My parents agreed that the central cooling and heating component always required professional know-how. Dad recalled a time at the farm when my dear old Grandpa had tried to repair a faulty heating component in the middle of winter. He ended up making the issue much worse, and they had to brave seven days in the chilly before an AC worker came over to repair the faulty heating unit. Dad had learned from an early age to consistently call the AC expert if there was ever an issue with the central cooling and heating unit. It truly was a miracle they had survived the Wintertide separate from heating that time. Once, the cooling component at lake new home was blowing cool air into the house. I guessed the issue was just a dirty air filter and asked dad if both of us could change it. He said no and instead called over the AC tech to come and check if that was the case.
