Furnaces are bound to make some noise. And often, the sound of light humming signals that the appliance is working well. BUT …
But it can become concerning when old noises suddenly become louder and the ones you’ve never heard stop popping up. And while some of them aren’t a cause for concern, others may signify a fault with your system.
Here are four scary sounds your furnace might be making and what you can do to make them stop.
If you hear rattling when your unit is on, there may be a screw loose somewhere. It could also be a small system component loosened and knocking around inside.
Luckily, this is a reasonably easy problem to diagnose. All you need to do is hire one of our expert techs, which will shut off the furnace and check around for loose pieces. It’s a job most homeowners don’t feel comfortable doing themselves, so give Air Repair Pros a call (469-333-2474) to more comprehensively diagnose and fix the problem.
Screeching or shrieking
If your furnace makes a sharp shrieking or screeching noise, it may indicate something is wrong with your compressor.
The sound may be a result of pressure building up in the compressor. And left unattended, this pressure can cause the compressor to fail and contribute to many other system-wide failures.
Unless you’re a professional, it’s not a good idea to try and deal with pressure built up yourself. So if you notice a shrieking sound, turn the appliance off and call in the Air Repair Pros!
Hissing is a sign that there is a gas leak somewhere in your heating system. And this is especially possible if your system hisses even while turned off.
Sometimes, the hissing sound may be accompanied by a wet gurgling noise. And this often means that your refrigerant is leaking.
Gas leaks are dangerous, and refrigerants are expensive to replace. So whichever case it may be, you must turn off your system if you hear these sounds and call in a professional to have a look.
Squeaking noises in a furnace system are often caused by gears and moving parts rubbing against each other. And after a while, this causes wear and tear on the system and makes it work less efficiently.
The easiest way to solve this problem is to turn off the system and lubricate its moving parts. Using an oil specially designed for furnace appliances, our professionals can regularly oil the bearings and motor shaft to extend your furnace’s lifespan and eliminate the squeaking noises.
