If your home is more than 30 years old, odds are it was built with components that are designed to wear down over time, and will need to be replaced.
Some of these parts can make noise when they haven’t been replaced.
If you hear a banging sound coming from your gas furnace, you may have a mechanical problem. If you are hearing a metal banging sound coming from your gas furnace, it is a good idea to turn off your Heating and A/C system, and contact your Heating and A/C provider right away. If you hear a high pitched whistling sound, you may have an airflow problem, however your air filter works to remove dust, dirt, and other debris from the air in your home, and eventually, your air filter can become obstructed with all of this debris. If your air filter becomes overly obstructed and is unable to correctly 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 A/C professionals recommend increasing your air filter every 30 to 60 days especially if you have pets, however another cause of an airflow problem could be a leak in your ductwork. The pieces of your ductwork expand and contract over time with the change in temperature, as well as can result in gaps in your ductwork, but having correct Heating and A/C upgrades and service is the best way to make sure that your system is in wonderful working order. Scheduling correct Heating and A/C appointments is the best way to make sure you don’t hear any unusual noises coming from your gas furnace.
