It’s late at night and you roll over in bed, fluff the pillow and close your eyes and start drifting into a bliss of slumber when, all of the sudden, you hear a loud noise coming from the basement.
Instantly, you know that the noise could only have been made by one of two entities; the furnace or the boogeyman, both of which reside in the basement.
Being a betting man, you place your money on the furnace and go back to sleep knowing you need to deal with it in the morning.
A properly functioning furnace shouldn’t make too much noise, at least not enough noise to startle you in the middle of the night.
Hage Energy, your HVAC service in Houston, will now run through some of the sounds you might hear from your furnace and what they might mean.
A clicking noise that comes from your furnace might mean that you have a faulty flame sensor that either needs to be cleaned or replaced. A clicking noise could also indicate a problem with the gas and the ignition system. Whichever problem it is, you will want to call your HVAC professional when you hear a clicking noise.
If you hear a chirping sound and it is coming from your furnace, it is pretty obvious what happened. You see, a bird must have flown in through the ductwork and is now trapped in your furnace.
All kidding aside, a chirping noise likely means you haven’t used your furnace in a while and it will go away when everything warms up. It could also be a loose belt that needs attention.
A constant rattling sound coming from your furnace could indicate that there is something broken in the motor or the fan is broken. If the rattling is really bad, it could mean your whole furnace is failing.
Whatever the cause of the rattling, it is quite obvious that you should be calling your HVAC team for help.
Popping and Banging Noises
It is pretty common to hear popping and banging noises coming from your furnace. Many times, these sounds will come from your ducts as they expand and contract in the cold and heat.
It is not unusual and quite normal for your furnace to make minor popping noises while in operation. However, loud banging and popping noises are a red flag and let you know something more serious is happening.
So you had better call your HVAC service.
A scraping noise coming from your furnace could mean that you have two metal objects rubbing together. It could be the blower wheel is rubbing against the casing or some other part of the furnace. It is a good idea to have a professional come over and take a closer look.
A screeching noise coming from your furnace could be due to a problem with the motor bearings. If this is the case, a shot of lubrication might resolve the issue. You should still call a professional to do the job because you need special lubrication to solve the problem.
A screeching noise could also be made by a belt that needs some attention.
A humming furnace is a furnace that is functioning well. The humming you hear should be soothing as it is letting you know that you don’t have to call your HVAC company.
Not all noises are an indication that something is wrong with your furnace. However, any changes in noise should be noted and a professional should be called to take a look at it.
