My younger brother is an experimenter.
We always thought he’d be a scientist, but he’s now a successful Jack of all trades.
None of us can ever forget the summer he was home alone and decided to run the ductless heat pump without air filters on. He was supposed to clean them, but a random Google search informed him they were unnecessary. When we got back home, our younger sister’s allergies flared up immediately after she set foot in the house, and my mother could not stop saying there was something odd with the air quality. My father was convinced he was doing drugs in the place and was about ready to kick him out when he spotted the filters. That explained the allergies and air quality. The young man was not apologetic, so he got tasked with paying for HVAC maintenance once the HVAC provider finished servicing because it would have to be cleaned off the dust trapped in it. The HVAC installation had never been that neglected. My parents were angry because an issue with the HVAC unit affected my sister immediately, and she needed constant help with indoor comfort. It’s why they bought such an expensive quality HVAC from one of the best HVAC brands, installed a thermostat, and kept an HVAC repairman from the local business on emergency calls in case anything failed. Once the HVAC professional came over, my brother had to join him in the cleaning as he handled the filters and any other work delegated and still paid for the service in full. We laugh about it now, but it took a long time for my parents to thaw the joke because they were worried about visiting the HVAC business for a new unit soon after that incident.
