It’s been raining this week and last week in Fresno, CA. This rainfall is very welcome, since we’ve been going through a drought and rain brings relief for farmers.

It looks like we’re going to enjoy a warm—or at least moderately cool—Thanksgiving here in the Central Valley. We can’t expect this to last, of course. By the end of December, the heating systems in our homes will be working regularly, and they’ll keep up their hard work through until April.
If you’ve had the same furnace in your home for many years, you’re probably accustomed to it having a pilot light. If you have newer furnace, or you’re planning on having one installed in the near future, it probably doesn’t use a pilot light at all. Instead, an electronic ignition system ignites the burners. In fact, you rarely see standing pilot lights on newly manufactured furnaces anymore. Why did this change happen? Let’s take a look.
