If your home is more than 30 years old, possibilities are it was built with components that are designed to wear down over time, plus will need to be replaced.
- Some of these parts can make noise when they haven’t been replaced, however if you hear a banging sound coming from your furnace, you may have a mechanical problem.
If you are hearing a metal banging sound coming from your furnace, it is absolutely a good idea to turn off your Heating and Air Conditioning system, and contact your Heating and Air Conditioning provider immediately. If you hear a high pitched whistling sound, you may have an airflow problem, but your air filter works to unclog dust, dirt, and other debris from the air in your home, and eventually, your air filter can become jammed with all of this debris. If your air filter becomes overly jammed and is unable to properly circulate air throughout your home, it may produce a high-pitched whistling sound. The solution to this is to simply replace your a/c filter. Most Heating and Air Conditioning professionals recommend changing your air filter every 30 to 60 afternoons especially if you have pets. Another cause of airflow problems could be a leak in your air duct. The pieces of your air duct expand and contract over time with the change in temperature, and can result in gaps in your air duct. Having usual Heating and Air Conditioning inspection and service is the best way to make sure that your system is in fantastic working order. Scheduling regular Heating and Air Conditioning appointments is the best way to make sure you don’t hear any strange noises coming from your furnace.
