Read on for some of the common furnace problems and how to solve them.

Insufficient Heat Production

Sometimes, your gas furnace may not produce enough warmth to keep your home comfortable, leaving you feeling the chill. 

This issue can result from various factors, such as:

• clogged filters,
•  worn-out gas furnace parts, 
• malfunctioning thermostat.

Another significant but often overlooked reason for this would be dirty burners which can prevent proper combustion and heating. Seek professional furnace cleaning assistance if your burners are dirty or are producing the wrong color flames.

Our skilled technicians can inspect your furnace, clean or replace clogged filters, and re-calibrate your thermostat to ensure your gas furnace operates efficiently. 

Call us if you’re experiencing insufficient heat production. With our service, you’ll soon enjoy the cozy warmth you expect.

Frequent Cycling

It can be annoying when the furnace frequently turns on and off. Besides, frequent cycling is one of the reasons you keep getting extremely high energy bills.

This problem, also known as short cycling, can be caused by a malfunctioning flame sensor, a faulty thermostat, or even an improperly sized furnace.

HVAC Santa Clarita will diagnose the issue, replace necessary components, and ensure your furnace functions smoothly. This will not only enhance your comfort but also reduce energy wastage.

Heating System Producing Odd Noises

Strange and unsettling noises from your furnace, such as banging, screeching, or rattling, should concern you. 

Depending on the noise you can hear, the problem behind weird noises could be:

•   Loose components,
•  worn-out blower motors, 
•  dirty burner

If your furnace produces a grinding or scraping sound, it’s a sign that the ball bearings have worn out. In this case, it’s best to turn off the unit and seek assistance from a qualified HVAC professional.

A squealing furnace often indicates a slipped or worn blower belt. If you’re comfortable with DIY repairs, following your owner’s manual, you can try to tighten or replace the belt. Otherwise, consider seeking professional help.

Our experienced HVAC technicians will identify the source of the noises, tighten any loose parts, lubricate moving components, and replace any damaged parts. This ensures a quieter and more reliable furnace.

Pilot Light Issues

A properly functioning gas flame should appear predominantly blue with a slight yellow tip. An orange flame often indicates incomplete combustion, resulting from various problems, including dirty burners, a lack of oxygen, or improperly adjusted gas flow.

Incomplete combustion can result in the exposure of carbon monoxide, a colorless, odorless gas that poses a severe health risk. If you observe an orange flame in your gas furnace, shut off the system, ensure proper ventilation, and seek immediate professional assistance to identify and rectify the problem.

HVAC Santa Clarita thoroughly inspect and repair the pilot light to ensure it burns and lights reliably. This is vital for the safe and efficient operation of your gas furnace.

Inconsistent Heating

If you notice that some rooms are too hot while others are too cold, it is a sign of inconsistent heating. This can result from:

• damaged ductwork,
• unbalanced airflow,
• malfunctioning thermostat.

Our expert installation and maintenance services ensure the proper ductwork and thermostat calibration, allowing for even heat distribution throughout your home. 

If you notice inconsistent heating or cooling, please contact us for furnace or AC repair Santa Clarita. 

Furnace Isn’t Receiving Power

Is your furnace not powering on? Start by checking whether it is plugged in. If it is, the next likely culprit would be a faulty thermostat. Ensure the thermostat is on and set to the correct temperature. Sometimes, a simple adjustment is all it takes to fix this issue.

Additionally, check your circuit breaker. If it’s off, flip it on. If it keeps tripping, consider involving a licensed electrician. This is one of the issues you may not need to call for professional heating repair Santa Clarita if you know where to look. 

If these steps do not work, then you may consider calling a professional HVAC technician. 

Popping or Pinging Ducts

Popping or pinging sounds in your ducts are often due to temperature-related expansion and contraction. Sometimes, a loose metal flap inside a duct may also be the cause. If you can pinpoint the source, a minor adjustment can often eliminate these sounds.

Remember to prioritize safety and consult professionals to enhance your gas furnace’s safe and effective operation.

Ductworks are delicate and often needs professional attention. Messing them up may interfere with the entire heat distribution process. 

Unusual Odors

Unusual odors emanating from your furnace can be a cause for concern. These odors might manifest as an acrid, metallic scent or something reminiscent of burning plastic or chemicals.

Such odors often indicate various issues within your furnace, ranging from a malfunctioning heat exchanger to a clogged air filter.

Moreover, unusual odors can sometimes indicate potential safety hazards, like gas leaks or overheating components. It’s crucial to address these odors promptly by turning off your furnace, evacuating the area, and seeking professional HVAC help to diagnose and resolve the problem.

Furnace Is Leaking Water

Have you discovered water leaking from your heating system? That is an issue of concern that needs professional intervention. If you are in Santa Clarita, call us for furnace or heat pump service Santa Clarita CA to solve the problem. 

The cause of leaking water could be a clogged condensate drain line, a cracked heat exchanger, or improper furnace installation. A clogged condensate drain line prevents water from draining away, causing it to overflow and leak.

On the other hand, a cracked heat exchanger allows combustion gasses to mix with air, leading to condensation and eventually water leakage.

To address this problem, it’s essential to shut off the furnace, inspect for the cause, and consult a professional HVAC technician to resolve the issue and prevent further damage to your heating system.

Dirty Filters

Air filters become clogged with gunk, dust, debris, and contaminants, obstructing the free flow of air. When this happens, your furnace will have to work harder to pull in and distribute air, leading to decreased heating efficiency, increased energy consumption, and potentially uneven heating throughout your home.

Furthermore, dirty filters can reduce indoor air quality as they fail to capture allergens and pollutants effectively. Regularly changing or cleaning your filters is essential to maintain optimal furnace performance, improve indoor air quality, and prevent unnecessary strain on your heating system.

Faulty Limit Control Switch

A malfunctioning limit switch in your furnace poses significant concerns for your heating system. This essential safety device monitors the furnace’s internal temperature, ensuring it doesn’t overheat. When the limit switch fails, it can result in several issues. It might cause the blower fan to run continuously, leading to uneven heating and excessive wear and tear.

Alternatively, if the switch remains stuck in the open position, your furnace may not produce adequate warmth due to a non-operational blower fan. Moreover, a closed switch can lead to overheating, risking damage to critical components and potential safety hazards. Timely professional attention is vital to rectify this problem and maintain your furnace’s safety and efficiency.

Malfunctioning Heat Exchanger

A malfunctioning heat exchanger within your furnace is a grave concern that extends beyond mere heating system issues. This crucial component plays a pivotal role in efficiently transferring heat, but it can lead to severe problems when it fails. First is the risk of carbon monoxide leaks, which is dangerous and potentially life-threatening. Additionally, reduced heating efficiency increases energy costs, while soot buildup can cause unsettling odors and visible residue.

Many furnaces shut down when a malfunctioning heat exchanger is detected, but continuing to operate it may lead to further component wear and system damage. Professional attention is vital to address this issue.

Troubleshooting Your Gas Furnace Problems: A Step-by-Step Guide

A malfunctioning gas furnace can disrupt your home’s comfort during the cold months. However, before calling a professional, performing some troubleshooting to identify common issues and potential solutions is often worthwhile. This guide looks into a step-by-step approach to help you diagnose problems with your gas furnace and possibly resolve them on your own.

Check the Thermostat

Do you suspect that the thermostat is the problem? Here is what you can do on your own:

• Ensure your thermostat has been set to your desired temperature.
• Confirm that the thermostat is in the heating mode.
• If the thermostat uses batteries, replace them and check for loose wiring.

If any of these do not work, it is a sign to call for professional HVAC repair.

Inspect the Power Supply

System not switching on? Power supply in a conventional gas furnace is a common problem that you should troubleshoot.

Start by verifying that the furnace is receiving power. Then, go ahead and check for blown fuses or tripped circuit breakers.

Examine the Gas Supply

Sometimes, the problem could be at the gas supply if the system doesn’t come on. To verify that the gas furnace is receiving gas as needed, take the following troubleshooting steps:

• Ensure the gas supply valve is open.
• Look for gas odors or hissing sounds, which could indicate a gas leak. If detected, immediately shut off the gas supply and contact a professional.

Gas supply is a serious issue that could result in safety hazards. Contact an HVAC professional near you if you’re unsure of the steps to follow.

 Replace Dirty Filters

A clogged filter is one of the significant reasons many gas furnace problems develop. Dirty filters can restrict proper airflow and reduce efficiency. Replace or clean them as recommended by the manufacturer.

Replacing furnace filters is one of the simple HVAC DIY maintenance you can do once every 1-3 months.

 Inspect the Pilot Light or Ignition

Not enough heated air? You should check the pilot light and ensure it is not the reason behind this problem.

Here is what to do:

• If you have a pilot light, check if it’s lit. If it’s not, follow the manufacturer’s instructions to relight it.
• For newer models with electronic ignitions, inspect for error codes or malfunctions on the control panel.

Check the Ventilation

If the furnace does not blow air as needed, the problem could be due to obstructions that need to be cleared.

Ensure that vents, gas lines and flues are clear of obstructions, such as debris or bird nests.

Investigate Unusual Noises

Strange noises may indicate issues with the furnace blower motor, burners, or other components. Listen for any unusual sounds and note when they occur.

Anything out of the normal, such as banging, screeching, hissing, or screaming noises, is a sign to contact a furnace repair technician.

 Observe Flame Color

The burner flame should be blue with a small, steady yellow tip. An inconsistent or predominantly yellow flame could indicate incomplete combustion.

Incomplete combustion is a serious safety hazard(1) that calls for prompt solutions. Call your HVAC tech if you notice this.

Remember that yellow flame color goes hand in hand with soot.

 Monitor System Cycling

How often does your gas heating switch on and off?

Pay attention to whether the furnace cycles on and off frequently (short cycling) or runs continuously. Both scenarios can signal problems.

Constant short cycling could indicate a dirty filter, thermostat, ducts or issues with the blower wheel.

This issue calls for quick, professional intervention as it causes speedier wear and tear and excessive energy consumption.

How To Prevent The Most Common Furnace Problems

Preventing furnace problems is cost-effective and essential for maintaining a comfortable and safe home environment during the colder months. 

Here are some critical steps to minimize the risk of furnace issues:

• Regular Maintenance: Schedule annual professional inspections and maintenance. Technicians can identify and address potential problems before they become significant issues.
• Replace Air Filters: Regularly replace or clean air filters according to the manufacturer’s recommendations. Clogged filters restrict airflow, reducing efficiency and increasing wear and tear on the system.
• Keep Vents and Ducts Clear: Ensure that vents, registers, and ducts are unblocked and free from obstructions, such as furniture or drapes. Adequate airflow is crucial for efficient heating.
•  Maintain a Clean Furnace Area: Keep the area around the furnace clean and free from clutter, flammable materials, or chemicals that could pose safety hazards.
• Install Carbon Monoxide Detectors: Ensure your home has carbon monoxide detectors. Regularly check their batteries and functionality to detect any dangerous CO leaks.
• Proper Ventilation: Ensure that combustion gasses are safely vented to the outside. Blocked flues or vents can lead to hazardous situations.
• Long-Term Planning: Consider replacing your current system with a more energy-efficient furnace. Modern, well-maintained units are not only more reliable but can also save on energy costs.

By proactively addressing these preventative measures and being attentive to your furnace’s condition, you can significantly reduce the risk of unexpected furnace problems, ensure a safe and warm home, and extend the lifespan of your heating system.

You, however, need to know that an old gas furnace may have constant problems due to wear and tear, or it is in its last years. Instead of blowing so much money servicing and repairing such a furnace, you’re safe calling us to perform a central heating installation Santa Clarita.
