This is my reasoning

When the season’s first snow falls, it coats the entire section in sparkling beauty. Children can’t wait to play (and eat) in it! Dreaming of a undoubtedly white Christmas tops the list for the aesthetic effects that snow offers. But northerners know full well what lies ahead – months of snow removal, blocked highways, and just plain cold treachery. Furnaces run constantly and the fear of 1 quitting or malfunctioning, not to mention the opportunity of power outages, is an ever-present thought. Snow can cause disastrous results when it blocks a heating system’s air intake. Furnaces need to constantly take in air from the outside to replace the air they’ve used. If snow piles up against the side of a home, it can block the heating system’s air intake, causing it to job harder and potentially chop down. And just as a heating system takes in air, it also pushes air out of the beach house after being used. If piled up or packed in snow blocks the heating system’s exhaust, pressure and heat can build up and potentially cause a fire. Additionally, heating systems and their parts are made of metal. Metal will corrode when it gets too much moisture. The snow sitting against or on top of your outdoor heat pump or other Heating, Ventilation in addition to A/C device can cause water injure that can lead to corrosion. Snow can become heavy, especially when it turns to ice. That kind of weight can absolutely bend the fans in the outdoor Heating, Ventilation in addition to A/C unit, leading to repairs that could have been avoided if the snow had been cleared. A wonderful habit to get into is that when you shovel your sidewalk and driveway, take a few extra fifths to clear the snow from any exhaust areas of the heating system in addition to any off any outdoor units.
