When the birds start singing and the sun finally feels warm, most of us are ready to shut off the heater and forget about it until the fall weather comes again. However, if your home relies on an older heating system, simply flipping the switch to “off” is a mistake that could cost you a lot of money later. These older machines have a lot of character. However, they also have many moving parts that get tired after a long, brutal winter of constant work. Taking a little time now to clear away the dust and check the belts ensures that your house stays safe and your heater is ready to roar back to life when you need it again.
Clearing Away the Winter Dust Bunnies
You need to give your furnace a thorough cleaning to remove the thick layers of dust that gathered while it was running 24/7. Older systems often have larger cabinets and more open spaces where hair, lint, and dust can settle. This buildup can actually become a fire hazard if it gets too close to the burner. You should grab a vacuum with a long attachment and gently suck up the gray fluff around the base of the unit and near the intake vents. By clearing out this debris, you are allowing the air to move freely. This prevents the motor from getting too hot and wearing out early.
Inspecting the Belt of the Machine
Older heating systems often use a rubber belt to turn the fan that blows warm air through your vents. These belts can dry out or crack after months of spinning in the heat. During your spring cleaning, you should turn off the power and take a peek at the belt to see if it looks frayed or if it has lost its tension. If the belt is loose, it might make a high-pitched squealing sound that can be very annoying and makes the heater much less efficient. You can test the tension by gently pressing on the middle of the belt with your finger; it should only move about half an inch if it is still in good shape. It is cheaper to have a professional replace the belt than to deal with an emergency caused by a system failure in the dead of winter.
Checking the Pilot Light and Gas Lines
Before you walk away from your heater for the season, take a moment to look at the pilot light to make sure it is burning with a crisp, blue flame. If the flame looks yellow or flickering, it could mean that the burner is dirty or that the gas mixture is not quite right. You should also sniff the air around the unit to make sure you don’t smell anything that reminds you of rotten eggs. This is a common sign of a gas leak, and it signals when you should leave your home and call a professional for help right away.
Taking care of these chores now gives you total peace of mind that your heater is resting safely and will be ready when you need it again. You can finally relax and enjoy the beautiful spring weather. If you live in Montgomery, AL or a surrounding area and need heating system services, make your first call to Alabama Home Pros.
