Common Furnace Problems and Solutions for Homeowners

February 28, 2024

With the winter months upon us, a reliable and efficient furnace is essential to keep warm in the homes of Richmond Hill, GA. However, they do run into the occasional troubles without proper care.  At Galbreath Heating and Air, we are here to help you avoid such troubles with regular maintenance. 

Common furnace problems we see faced by homeowners and their solutions:   

  • Uneven Heating and Cold Spots 
  • Strange Noises or Banging Sounds 
  • Frequent Cycling On and Off 
  • Pilot Light Issues and Ignition Problems 

Uneven Heating and Cold Spots 

In Richmond Hill, GA, one of the most common furnace problems we encounter is uneven heating and cooling. This can be due to a variety of reasons, including leaks, restricted air flow, or inadequate installation. At Galbreath Heating and Air, we have some of the best solutions to keep your home ‘evenly’ warm this winter! 

  • Adjust the Airflow. We recommend adjusting the airflow of the vents throughout your home to avoid uneven heating and cooling. Partially, but not entirely, close the vents on one level of your home.  This will redirect the air and alleviate pressure build-up in the system. 
  • Ensure Proper Installation of Furnace. Occasionally a mid-sized furnace or ductwork will be installed in a home. This can cause several issues, including uneven heating and cooling.
  • Inspect Leaks. It is recommended to have a professional come to your home at least once a year to do a full leak inspection of your heating system.  If there’s a leak, it can cause the air meant for an intended location to leak before it arrives.  
  • Add Insulation. Without proper insulation, homeowners cannot get the full benefit of their heating systems.  
  • Consider Zoning Systems. Zoning systems are a great way to avoid uneven heating throughout your home.  It allows you to control temperatures independently by floor.  
  • Air Filter Replacement. Air filters are responsible for collecting air particles, such as dirt and debris, to keep the air throughout your home clean and ensure your furnace is working correctly.  At Galbreath Heating and Cooling, we recommend replacing your air filter at least once every three months. 

Strange Noises or Banging Sounds 

If you are hearing rattling or whistling sounds throughout your home, it might be time to schedule a professional inspection. Strange noises are never a good sign. They could indicate issues with the blower motor, loose components, or even a clogged burner. 

Here are a few of the noises you may hear because of a faulty system: 

  • Scraping Noises. This typically indicates that your blower motor is either broken or loose. If this is left unresolved, it can lead to wear and tear. If you notice this sound, turn off your furnace immediately and call a Galbreath Heating and Air professional! 
  • Whistling Noises. Just as scraping noises, whistling noises are often due to issues with the blower motor. This is often due to a lack of airflow in the heating system. To solve this issue, we recommend replacing your air filter. 
  • Rattling Sounds. Rattling sounds usually means there is a loose screw on the panel or door. To resolve the problem, tighten the screws. If it continues, this could indicate a loose part. A rattling sound could sometimes mean a crack within the heat exchanger. We recommend turning off your furnace and calling a professional. 

Frequent Cycling On and Off

A common furnace trouble that homeowners often overlook is short cycling. Short-cycling is when your furnace turns on and off frequently, so it is not completing its cycle as intended. 

Below are several potential causes of this sort of furnace malfunction: 

  • Thermostat Issues. The thermostat is the brains behind your heating system. It is in charge of sending signals to your furnace to set the proper temperature. A malfunctioning thermostat could cause short cycling if it is incorrectly reading temperatures. 
  • Clogged Filters. A clogged air filter often leads to little airflow throughout your home. This can indirectly cause the furnace to short-cycle due to overheating. 
  • Cracked Heat Exchanger. A cracked heat exchanger is one issue that cannot be ignored. Short cycling will occur due to overheating. This could release carbon monoxide throughout your home, putting you and your family in danger. 

When your furnace is short-cycling, it is important to seek professional help.  Without proper treatment, it could lead to costly repairs or, sometimes, replacement. 

Pilot Light Issues and Ignition Problems 

Every single component within your furnace plays an essential role in providing warmth to your home, including the pilot light. The pilot light is responsible for igniting the furnace. So when it’s out, your furnace will not be able to produce heat to keep your home warm. 

Every once in a while, it will go out due to drafts or poor ventilation. In some cases, it could result from a faulty thermocouple, a dirty pilot orifice, or gas supply problems.  

  • Faulty Thermocouple.  A thermocouple serves as a sensor to measure temperature. It is a combination of a tube, a bracket, and wires. The best way to diagnose a faulty thermocouple is with an open circuit test done by a professional technician.  
  • Dirty Pilot Orifice.  If your furnace is facing troubles, it could mean a dirty pilot orifice. When the pilot orifice is filled with dirt and debris, the pilot light won’t be able to light properly.  When it comes to cleaning a pilot orifice, it is recommended to disassemble the pilot and use a needle to clear out debris. 
  • Gas Supply Problems. When your pilot light doesn’t activate, it could be due to gas line issues.

Brandon is AWESOME!!! I have a new build home that’s almost 4 years old and experiencing HVAC issues. I originally had a different company come out that said I have a leaking coil and in total recommended close to $10K repairs to fix. Also they said the coil was on back order and never called me again. Awesome. Brandon came out for a second opinion and he was extremely polite, patient and courteous. He explained everything thoroughly and did not try to upsell us on unneeded items. His recommended fixes made sense and the infamous coil… their company called on the spot and found one that we could have in 1-3 business days and we walked away paying half the cost of the original quote. For anyone in the coastal Georgia area, Galbreath is a great option. We won’t go anywhere else from now on!
