Most system failures aren't random. They're the end result of something small that went unaddressed for one or two seasons too long. A heat exchanger crack that started as a stress fracture. A capacitor that was running hot for months before it failed on the warmest day of July. A humidifier water panel so scaled over it stopped doing anything useful. Annual HVAC maintenance catches these things when they're cheap to fix. It also keeps the equipment running at the efficiency it was rated for — a dirty or maladjusted system uses more fuel to deliver the same heat. Over a full heating season in Minnesota, that adds up.
