The weather has begun to cool, and we’re reminded of just how close winter is. Soon we’ll be running our heating systems on a daily basis. If you are anything like the average homeowner, it’s very likely that you have a furnace, the most popular type of home heating systems across the nation.
But before you start to use your furnace, it’s essential that you schedule preventive heating maintenance—and also that you change your air filter. This filter protects both your furnace and central air conditioner, which will have collected plenty of debris of the summer. If the air filter isn’t changed on a regular basis—every 1 to 3 months during periods of use—then you can run into problems.
