Is your furnace making strange noises or have you observed that your unit is blowing cold air when you’re expecting a comfortable blast of warm air? If so, it could be a indication that your HVAC equipment is about to fail before the cold winter season is here.
If you hear a loud scraping sound that sounds like metal on metal, there is likely something wrong with the blower wheel. If you hear a sound like this, turn off your furnace immediately and call a Heating Service in Chatham NJ to investigate the furnace. It might just be loose and if the piece is not too damaged, can be tightened or it might be that the motor mount is broken, causing the complete blower assembly to shake uncontrollably.
If there is a loud pop when your furnace kicks on, there are two problem areas that could be causing problems; dusty furnace burner or ignitor. A dirty furnace burner or ignitor could keep the burners from igniting, causing gas to build up. When the gas finally does ignite, it will create the loud bang you hear. This could result in a safety problem, especially if one of these small explosions caused the heat exchanger to crack.
