If you have recently noticed strange noises coming from your furnace, you may be dealing with a faulty equipment. Unusual sounds coming from HVAC systems are never a good sign, as they usually tell you that some components may not be working properly and that prompt furnace repair is necessary. In this blog, we are exploring the meaning of each type of noise and what you can do to keep your furnace in optimal condition.
Whistling
A whistling noise coming from the return air ducts generally means that something is wrong with the air flow inside your unit. This is typically caused by a dirty air filter, which is a problem that needs to be tackled quickly. Filters are responsible from preventing debris, pet dander, dust and other small particles from getting into the system. With time, however, these filters can get very dirty, preventing air from properly circulating inside your unit, which ultimately leads to low performance and reduced heating capacity. Experienced professionals recommend that you have your furnace filters cleaned once every three months. However, prompt cleaning or replacement may be necessary in case you hear whistling noises.
Grinding
Grinding noises may be a sign that you may be dealing with a motor bearing issue. Bearings can make noise if they are installed incorrectly or if they are worn out due to extensive use. Regardless of the reason, keeping bearings in optimal condition is fundamental to ensure your furnace can perform well and provide you with efficient heating. If you hear grinding noises coming from your furnace and you suspect something may be wrong with its internal components, it’s recommended that you rely on professional help for replacement.
Rattling
Rattling can indicate a wide number of issues in your furnace. In some cases, rattling may simply indicate a loose bolt, which is something that you can repair yourself by simply tightening the loose part. However, rattling may also mean you are dealing with more serious issues, such as a crack in your heat exchanger. If simply DIY solutions can’t get the noise to stop, professional assistance may be necessary. Skilled technicians will be able to identify the noise, diagnose the problem and repair your furnace with efficiency and accuracy.
Popping or Banging Noises
Popping or banging noises in your furnace may be a strong sign that your burners are faulty or dirty. What happens is that furnaces with dirty burners will take considerably longer to ignite, which leads to gas build up. When it finally ignites, small explosions happen inside the unit, which can cause cracks and other types of damage in its structure. To prevent more serious issues and expensive repair services, it is important to get your burners cleaned at least once a year.
