Furnaces have long ranked among the most popular of all home heating systems, and they are not likely to be unseated from the throne any time soon. They are highly effective, provide prompt heating throughout the house via their use of ductwork, and modern models are quite efficient. At least, this is all true when the furnace is in the best working condition possible. Scheduling routine maintenance can help to ensure that this is the case.
However, there is also one important step that you must take on your own if you really want to get the most from your furnace. That is to change your air filter as needed. Typically, this is every one to three months, though we suggest that you err on the side of caution and do it on the more frequent side of that range. Yes, your technician will change the filter during your tune-up, but once a year is not enough. A fresh filter can help to stave off furnace repair in Ankeny, IA.
