Your furnace is a pretty expensive appliance in your home. You need to keep it well maintained if you want it to continue to work properly and efficiently year after year. Part of furnace maintenance is paying special attention to odd noises and other things that are out of the ordinary - ignoring warning signs can lead to bigger and costlier issues. See below for some warning signs you should look out for with your furnace.
If your furnace is making rattling noises, it could be the start of a broken heat exchanger. If your heat exchanger is broken, it can cause toxins to be released into your home. A rattling noise can also be a sign that a door panel is loose. It's best to turn off your furnace and have it looked at by a professional, just in case.
Flickering Pilot Light
Your pilot light should glow blue. If it is flickering or yellow, it could be a sign that there is too much carbon dioxide. You can make an adjustment to the pilot light screw to see if that helps turn the pilot light back to blue. If it doesn't turn back to blue, you may want to call a furnace repairman.
If your furnace is making a squealing noise, it could be a sign that your blower belt is bad or slipping (the blower belt is usually located towards the bottom of your furnace). It could also be a sign that the ball bearings near the blower need to be lubricated. Turn off your furnace to try and lubricate the bearings to see if that helps. If it doesn't, inspect the blower belt and have it replaced if it is frayed.
Other Warning Signs
Proper maintenance of your furnace, including watching for warning signs will help lengthen the life of your furnace. If you have any of these issues, contact a company like Custom Comfort Heating & Air Conditioning Inc to come check your furnace out for you and take care of any necessary repairs.Share

After saving money for years, I was finally ready to build my dream home with a team of professional contractors. I started by talking with the team about what I wanted, and then we moved forward with our plans. It was really incredible to see the things that I wanted come to life, and within a few months, my home was underway. I can honestly say that I was incredibly pleased with our construction team, and I couldn't have done it without them.
