Every year, homes are at risk of fire due to malfunctioning heating systems. There are ways to help lower your risk of having a fire in your furnace. One of them is to have a furnace repair service tech come into your house and give your furnace a checkup in the fall. There are several things that the service tech will look for when they check your furnace out.
Soot can end up on the inside of the burner of your furnace. Soot is an inescapable by-product of fire, so it can be hard to avoid getting it in the burner. However, soot is also flammable. When the service tech is checking out your furnace, they will clean out the burner, getting rid of all the soot. If there appears to be more than is reasonable, the technician will do an examination to see if they can find out where it came from. You don't want to risk the soot building back up quickly.
Nuts and Bolts
Even if a loose nut doesn't cause serious problems, the sound of it rattling around every time your furnace turns on may drive you to distraction. However, there is always the risk that a loose nut or bolt will fall down into the blower or into some other part of your furnace, thus destroying your furnace. Making sure everything is right and tight may seem like it's not all that important, but it really is.
Your furnace has to have some way to light up. If your ignition switch doesn't turn on every time it's triggered, then you aren't getting any heat. And the switch always seems to fail on the coldest night of the year. If you have to have it repaired then, you are going to end up with a huge repair bill and a long, cold wait. Making sure that your ignition switch triggers when it should will help make sure that you don't wake up cold in the middle of the night. One way that the service tech can tell if your ignition switch is a problem is by using a volt meter. What they will do is take the leads on the volt meter and attach them to the ignitor plug. They are looking to see if the ignitor puts out 220 volts when it kicks on. If it doesn't, then the switch should be replaced.
Hiring a company that offers furnace tune up services every fall is no different than going to the doctor's office and getting a physical. It's a way to make sure that problems are caught before they get bad and that everything is working the way that it should.
