One of the best ways to determine if something is wrong with your furnace is simply by using your ears. Even if you know nothing behind the mechanics of a furnace, there is a typical pattern of sounds you will hear when it is fully operational. When an odd sound becomes a part of the mix, it's time to call a professional contractor for furnace repairs before the sound gets worse.
To help determine the source of your problem, follow this onamonapia guide. It will help give you a better idea of the problems that are occurring and the next steps to take before calling a professional.
When listening closely to your furnace pipes, you may hear a gurgling sound. This is a similar sound to if you were draining the bathtub. When this sound occurs, it means that your pipes have air flowing through them. When air gets into the pipes, it normally automatically comes out of the pipe after a complete cycle. This is due to the pressure regulator pushing out the air in the form of steam.
If the gurgle sound continues for more than an hour, then there may be a problem with the pressure regulator. A furnace repair specialist can determine if there is a clog in the regulator. This can often happen if you have hard water.
The clicking sound you hear near a furnace is the device igniting to burn oil and create heat. Anytime the furnace is set to turn on, this clicking is completely normal. If you hear long patterns of clicking without the furnace turning on then you likely have an ignition problem. When this occurs, the furnace will not power up and needs maintenance to get running again. Along with a cleaning, a repair specialist can install new parts to ensure that the furnace starts right every time.
Fans and motors help cool and run the furnace. If you hear a deep grinding from inside the furnace, then there is likely a jam or problem with it. One of the biggest reasons that these problems can occur is if dust or debris has built up inside of the furnace. This is usually due to environmental conditions and a lack of cleaning for the furnace.
The first step to fixing this problem is a professional cleaning. When a cleaning is done, all of the furnace components are taken apart, examined, and cleaned. If the problem persists, the repair specialists will replace fans and motors as needed. If your furnace is grinding, you should use the shut off switch until a specialist arrives. The furnace could overheat and pressure could increase, causing even more problems.
This is one of the easiest sounds to decipher. The drip-drop from your furnace means that water is leaking from some point. The first place to check is the boiler drain valve. This is a small faucet at the bottom of the furnace used to drain water. Ensure that the valve is completely tightened to prevent leaks. If water is still leaking from this valve then repairs are needed.
Water may leak from inlet valves. If the valves have rusted or worn down, they could leak and may need replacement. A furnace specialist can complete a full inspection to determine where all the water leaks are. If possible, you should turn off the furnace until a contractor can arrive.
One of the worst sounds you can hear from your furnace is no sound at all. This means that the furnace has completely shut down and is malfunctioning. Before attempting to turn the furnace on and off, a professional should come in to help figure out the exact cause. It could be a power issue or a broken part.
Write down the sounds you hear with as much detail as possible. This will help a professional make a diagnosis as quick as possible.
