When heating season is over, all you can think of is getting ready for nice weather. You aren't thinking about the upcoming heating season. You're just concerned about turning off your heater and getting your windows open. However, you should summerize your furnace, just like you winterize your home.
Soot and Scale
Even the best, cleanest running furnace is going to end up with soot and scale on it at the end of the year. The best time to get it cleaned is after the heating season. There are several reasons for this. One of these reasons is that the soot and scale will often contain sulfur. Any leftover sulfur in your furnace can actually start to damage the burner, especially if it's left there for years. Getting rid of all that soot and scale will not only minimize the risk of the damage that the sulfur can cause, it can also help your furnace run better when it's time to start again.
Fill Your Tank
If you use heating oil, propane, or similar fuel in your furnace, this is actually the best time to fill it up. Generally prices tend to go down in the summer. Lower demand means that the fuel suppliers need to sell their inventory somehow, so they will discount their prices. You can fill it up over the summer, at a lower price, to have it ready for winter. The fuel shouldn't break down or go bad over the summer.
Have Your Furnace Inspected
If you have any worries that your furnace isn't working as well as it should be, this is the time to get it checked out. Heating companies like Lowry Services: Electric, Plumbing, Heating & Cooling are going to have more time to work on your furnace during the summer than they would in the middle of winter. Any problems can be handled then, and you won't have to pay for an emergency call. The heating contractor will also be able to tell you if this is a good time to get your furnace replaced. All routine maintenance can be handled during this checkup too. That includes tightening bolts and belts.
You want to be able to enjoy the nice warm weather and hot have to worry about what is going to happen. Summerizing your furnace will let you be sure that when the warm weather is over and the cold weather returns your furnace will be ready to turn on and keep you warm.
