Heating systems are rarely ever completely silent. But that does not mean one should ignore all the sounds coming from it. Where some sounds are normal, all are not. Therefore, every homeowner should pay attention to those sounds that are different from the ones that it usually makes. To make things simple, we shall discuss the abnormal sounds and understand the reason behind them.
At the end of the read, you should be able to identify those noises from the heater that indicate the need for technical help from a qualified technician. If it comes to your notice that your heating system is making any of these noises, contact your local HVAC technician without further delay.
If you are concerned and think your heater in West Palm Beach is making some unusual and odd noise, get in touch with the team of Aztil Air Conditioning.
Heater Noise That Should Raise A Red Flag
If you can differentiate between typical heater noise and the ones that are indicative of trouble, you will be able to save yourself from unnecessary worry and expense. These are some sounds that you should be concerned about:
1. Banging – A loud bang when the heater kicks on is a sign of an ignition issue. In an ideal scenario, the thermostat sends a signal to the furnace to start the heating cycle. At this time, the gas valve opens, and the pilot light ignites the gas simultaneously. When there is a problem with the ignition, some gas builds up inside the combustion chamber. By the time it ignites, there is enough gas within the chamber to create a BANG. This sound travels through the ducts, and you can hear it. Several reasons could lead to ignition problems, for example, dirty burners, weak flame, or low gas pressure.
If you hear a continuous banging sound, it tells you that some component is either broken or loose inside the heater. Similarly, if you hear the banging sound a couple of minutes after the furnace cycles ON and OFF, it tells you that the ductwork is expanding and contracting due to the temperature change.
2. Whistling – The whistling sound is produced when the air is forced to pass through a very narrow space. Hence, it indicates airflow issues. Whistling can be heard if there is an issue with the blower or the burner, the air filters are clogged, there is a blockage in return air ducts, vents and dampers have been closed on purpose or accidentally, etc. In the case of dirty air filters, you can either replace them yourself or call a technician to handle it.
When the cause of whistling is a faulty blower or burner, it is best to let the HVAC technician get to the bottom of it. A trained professional will be careful and rectify the problem without making things worse.
3. Clunking – Clunking sound is easy to identify. It resembles the sound of someone knocking. Usually, when the blower fan gets displaced from its position, it makes this noise. It is actually the sound of the fan blades hitting the walls or some other furnace component. Another possibility is a ripped fab belt, where the torn portion is striking against something else in its path. In either case, an HVAC technician is the most suitable person to solve the problem.
4. Clicking – When the heater’s electronic parts respond to the thermostat signals, they produce a clicking noise. For example, when the thermostat commands the furnace to begin heating, you hear a clicking sound as the heating initiates. In the same manner, you may hear a similar sound when the flame igniter tries to begin the combustion process by lighting the burners. These clicks are all normal and part and parcel of the heater. Nevertheless, if you hear a similar sound when the heater shuts off, you may have to worry about a cracked heat exchanger. A cracked heat exchanger is a dangerous situation, and you should refrain from using the furnace at such a time. Whenever you suspect such trouble, switch off the heating system and call the technician immediately.
Aztil AC provides emergency services round the clock. If you suspect a cracked heat exchanger in your home’s heater in West Palm Beach, immediately call Aztil Air Conditioning for emergency repairs.
5. Squealing – That jaw-jarring sound when metal rubs against metal is the squealing or screeching we are talking about. And that is exactly what produces this noise. The sound can be heard when the displaced fan drags against a metallic component. It could also be a result of a lack of lubrication between moving parts. If you are careful and follow a strict heater maintenance regime, you should not hear this sound. Nevertheless, if you still do, call your contractor for rectification of the issue.
The heating system is like your car. The more you use it, the easier it becomes to distinguish between normal and abnormal sounds. As the system ages, the sounds will also increase by a few decibels, but you will still be able to recognize the strange ones. Squealing, screeching, whistling, banging, and knocking sounds should not be ignored. It is always better to get them checked once by the technician. If he gives a green signal, all’s well. If he says it’s a red flag, seek its repair pronto. Taking care of the heater will ensure that your machine is reliable and will not give you unnecessary trouble. Therefore, see to its proper maintenance. Above all, never ignore any problems. Ignoring them will not make them vanish. Instead, it will come back to bite you in the form of an expensive repair or replacement.
