If your furnace has any concerns, it doesn’t take a scholar to know that when it snows, the furnace is going to cut down. It doesn’t need to be snowing to make the furnace suddenly quit working. Any kind of inclement weather, including extreme cold, will supply the furnace the impetus it needs to finally quit. Maybe you’ve never experienced this, but I have. Twice in the last fifteen years, our furnace has died while in the worst weather in the season. The HVAC worker told myself and others the reason was because the furnace is working hard to keep up with the weather. It is trying to argument off the chilly so you can stay warm. Any components that aren’t perfect are getting added strain plus are bound to cut at that time. You can explain that it is an overworking furnace, or Murphy’s law, or that our furnace is taking this option to get back at myself and others for now being more vigilant. Whatever you say, it still doesn’t make it easier to take when your furnace breaks down while in a stage of honestly awful weather. This has happened to myself and others twice in the last fifteen years. Within a year of buying our home, I had to have the HVAC plan updated. Fifteen years later, while in the blizzard of a lifetime, our furnace, which was fifteen years old, died. When you’re left out in the chilly for almost a week because of no furnace, it doesn’t make for a good week.
