Why Is My Boiler Making Loud Noises?

Why Is My Boiler Making Loud Noises?

It can be very unsettling to find your boiler producing loud and unpleasant noises. You might wonder what could be the cause of the noises or even presume your boiler has sustained damage. However, boiler noises should not cause you to panic. If you find your boiler making loud noises contact A-Plus Quality, HVAC services in the Greater Toronto Area, to have the problem diagnosed and fixed. A certified technican will check for the source of your boiler noises and make any necessary boiler repairs. 


Possible Causes of Boiler Noises

During the diagnosis of the cause of your boiler noises, an HVAC technican will consider the kind of sounds produced. This action gets carried out to deduce the source of the problem. The type of noises taken into consideration are:


1. Kettling Noises

Clunking sounds and banging sounds are called kettling. If your boiler produces such noises, the problem might be that the boiler has developed limescale inside. This limescale creates a layer in-between the heat exchanger, making kettling noises as the water inside boils through it.


2. Whistling Noises

This kind of noise is very alarming to most people. However, they are not signs of severe boiler damage. These sounds relate to kettling or sometimes caused by trapped air inside the boiler. Other causes of whistling sounds are partial blockage of pipes or a rapid increase in water pressure due to overheating.


3. Gurgling Noises

In most cases, the cause of this kind of noise is likely trapped air in the boiler. This often culminates from leaking pipes. During cold seasons production of gurgling noises by the boiler indicates frozen pipes.


Solving Boiler Noises

If you identify the above noises emanating from your boiler, contact us today and a certified techinican from A-Plus Quality, HVAC services in the Greater Toronto Area, will help you fix the issues. If they find air trapped in your boiler, they will check for pipe licks and fix them. However, if there are no licks, they will arrange to drain the trapped air from your boiler.


If you are concerned about any odd noises coming from your boiler, contact us today and we will send a specialist from A-Plus Quality, HVAC services in the Greater Toronto Area, to inspect the problem in detail. Contact us today!

Client Testimonials

  • First experience was on New Year's Day, 2020, when furnace stopped. Called A-Plus and they had a rep (Jack) out quickly. He did some troubleshooting. He wasn't giving BS. Gave me options on repairing or replacing. Non-biased, no pressure. I chose replace and it was done the next day. Good experience all around. Second experience was early March, 2021 when a harsh chemical smell emanating from the furnace room, and pushed through the HVAC venting, permeated the house. Very concerning. Was late night, called A-Plus, immediately answered and suggested some safety moves for the evening. Booked a visit for the morning. Jack again came and assessed the issue and advised where the smell came from (outside). Again, very professional, quick, no BS, good guy. Completely satisfied with the service after often being given the BS treatment from other service providers for the house. Would definitely recommend.

FAQ

  • How do I know what size unit I need?
    If you have any problems with your system, you should contact the contractor who installed the units. All our systems are covered by a 5 year parts, 7 year compressor limited warranty
     
  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • Why should I maintain my Furnace or AC?

    An annual maintenance will extend the lifetime of your heating and cooling unit. The technician will diagnose and repair any problem with the unit before it fails, so you won't need to worry about any problems when the weather gets very hot in the summer or extremely cold in the winter.

  • Furnace is blowing cold air in Winter?

    This can be due to Ignition lockout, sometimes could be resolved by resetting the power  and if this does not resolve the issue you should contact a certified gas technician from A-Plus Quality to get this problem resolved!
