As you test your furnace this fall, and once you begin using it, it's wise to be on the lookout for any signs that your system is developing a problem. Unusual furnace noise is often an indication of a problem. The following will assist you in identifying some of the furnace noises you should listen for, and what they may mean. As you test fire the furnace this fall, contact Garland Heating and Air Conditioning for the repair, installation or the annual fall maintenance of your heating and air conditioning in Dallas, TX.
Booming. Grumbling or Clicking
If your furnace makes a grumbling or loud booming noise when it turns on, the foremost concern is a problem with the burner assembly. The burner assembly is the component that burns natural gas in order to generate heat. Over time, carbon from the burning of natural gas will build up on the burner assembly. If the assembly isn’t routinely cleaned, it will clog with the deposits delaying its ignition of the gas. When this occurs, gas builds up once the system turns on, and it is the ignition of excessive gas causing the booming or grumbling sound.
Contact your HVAC technician for annual service and maintenance of your home's heating and air conditioning in Dallas, TX. Booming or grumbling may also indicate holes in the burner chamber if your system has been well-maintained. Call for service as this is a potentially hazardous condition. Clicking can also indicate issues in the burner and/or other related components.
Grinding or Screeching
The air handler is the part of a furnace that turns the fan, which is responsible for circulating air throughout the home during operation. The air handler, or fan motor is equipped with oiled bearings which facilitates its smooth operation. Over time, the bearings will wear out, causing friction and generating a loud grinding or screeching sound. If you hear this sound, call for furnace repair immediately. The bearings must be replaced before the motor burns itself out. Though not common fire is a potential hazard. Routine maintenance of your heating and air conditioning in Dallas, TX will reduce wear and tear and ensure the bearings are lubricated.
Rattling and Squealing
Some older furnaces are equipped with a blower motor belt, which when worn can throw the blower motor off balance and create a rattling sound. A loose fan or worn motor may also cause a rattling sound. In addition, the belt may slip, producing a high pitched squeal. Other potential causes of squealing include a worn fan and/or fan motor.
Air leaks in the ducts or ventilation system can create a high pitched whistling noise.
