Last summer, I was tasked with explaining to my husband how our new HVAC system works. My husband has never been the type to express interest in cooling technology. He likes math, so he handles all of our financial affairs while I handle the dirty but fun maintenance on the house and our cooling system. He traveled extensively and was away for roughly three weeks in the spring. He was happy with the upgrade, better air quality, and contribution to indoor comfort, but when he got home he still had to figure out how to use the new, high-quality air conditioner. While he was away, our heat pump malfunctioned, necessitating a visit from the cooling representative of the nearby cooling company. After inspecting the device, the cooling specialist discovered that it was broken because one of its vital parts was worn out. It was a wise purchase even though it was expensive for us. I purchased a central air conditioner and set up an indoor air cleaning system to keep the air clean and free of contaminants and viruses. The technicians had to teach me more about air conditioning and how to change the air filters because dust can get into the delicate parts of the unit and cause issues. The importance of regular AC maintenance was emphasized by the technician. My husband stopped misinterpreting the purposes of the thermostat buttons after a day. Over the course of the summer weeks, he mastered using the mini split air conditioner to the point where he even created the first maintenance schedule. He kept referring to himself as an authority on the cooling industry.
