Top 5 Signs Your Furnace Needs Repair in Roseville, CA

A well-functioning furnace is essential to keeping your home warm and comfortable during the colder months. If your furnace starts to show signs of trouble, it’s important to address the issues quickly to avoid discomfort or expensive repairs. At Economy Heating & Air, we specialize in diagnosing and fixing furnace problems in Roseville, CA. With over 30 years of experience in the HVAC industry, our team is here to make sure your furnace keeps running smoothly when you need it most.

Here are the top 5 signs that your furnace may need repair.

Strange Noises

When your furnace makes unusual sounds like banging, whistling, or rattling, it’s often a signal that something’s not working as it should. Each sound can point to underlying issues that, if left unchecked, may lead to more serious damage.

• Banging Sounds: This loud, unsettling noise typically occurs due to delayed ignition in the burner. When the burners in your furnace don’t ignite immediately, gas builds up in the combustion chamber. When it finally ignites, it can create a small explosion, resulting in a banging or popping sound. Delayed ignition can be caused by dirty or clogged burners, which restrict the flow of gas, preventing immediate ignition. Over time, this can strain the furnace and increase the risk of damage to the heat exchanger, which could lead to costly repairs or even a complete furnace replacement.
  
  
• Whistling Noises: A high-pitched whistling noise usually indicates restricted airflow. This is often caused by a dirty or clogged air filter, which forces the furnace to work harder to push air through the system. If airflow is severely restricted, it can cause the furnace to overheat and shut down prematurely, leading to inconsistent heating and potential damage to internal components. In some cases, whistling can also result from poorly sealed ducts or closed vents. Replacing the filter regularly and ensuring vents are clear can help prevent this issue.
  
  
• Rattling Sounds: Rattling often points to loose parts or components in the furnace. Over time, screws, bolts, or panels may become loose due to normal wear and tear. In some cases, rattling may indicate a more serious problem, such as a cracked heat exchanger or a failing motor. Loose parts can cause vibration that might worsen and lead to more significant damage to the system if not addressed promptly. Ensuring routine inspections and tightening of components can help catch and fix these issues early on.



If you’re hearing any of these sounds, it’s crucial to get your furnace inspected by Economy Heating & Air to prevent further damage and make sure your system runs safely and efficiently.

Inconsistent Heating

Inconsistent heating throughout your home is a frustrating and common issue that can indicate problems with your furnace. When some rooms feel too hot while others remain cold, it usually points to airflow or mechanical issues that require attention.

• Blocked or Dirty Filters: A clogged or dirty furnace filter is one of the most common causes of uneven heating. The filter’s job is to trap dust and debris before they enter the furnace’s blower and ducts. Over time, if the filter is not changed regularly, it can become clogged, restricting airflow. This leads to rooms farthest from the furnace receiving less heat, while rooms closer may get overheated. Replacing your furnace filter every 1-3 months can help maintain proper airflow and even heating throughout your home.

• Leaky or Blocked Ductwork: Ductwork carries the heated air from your furnace to the various rooms in your home. If your ducts have leaks or blockages, some areas may receive less heated air, causing inconsistent temperatures. Leaky ducts can allow heated air to escape before it reaches certain rooms, making those rooms colder. Blocked ducts, on the other hand, can limit airflow altogether. Proper duct cleaning and sealing can help ensure that air flows evenly to every part of your home.

• Thermostat Issues: If your thermostat is malfunctioning or located in a poor spot, it may not accurately reflect the temperature in all parts of your home. For example, if the thermostat is placed near a heat source or in direct sunlight, it may register the room as warmer than it is, causing the furnace to shut off too soon, leaving other rooms cold. Upgrading to a programmable or smart thermostat can help regulate the temperature more effectively throughout your home.

• Imbalanced Dampers or Closed Vents: Your heating system likely includes dampers within the ductwork, which help control the amount of heated air directed to each room. If the dampers are improperly adjusted or some vents are closed, it can cause uneven heating. Balancing these dampers or ensuring all vents are open can improve the distribution of heat across your home.

Inconsistent heating not only affects your comfort but also forces your furnace to work harder, leading to increased wear and higher energy costs. Regular maintenance or repairs from our team can help restore even heating throughout your home, as part of our comprehensive heating services.

Rising Energy Bills

A sudden spike in your energy bills could mean your furnace is becoming less efficient. As your system struggles to maintain the desired temperature, it consumes more energy, driving up your costs.

• Aging Furnace: As furnaces age, they lose efficiency. Older units—especially those that haven’t been properly maintained—tend to require more fuel or electricity to provide the same level of heating. In fact, furnaces over 15 years old are often less energy-efficient than newer models. Upgrading to a newer, high-efficiency furnace, such as a model rated with an Annual Fuel Utilization Efficiency (AFUE) of 90% or higher, can result in significant savings on your heating costs.

• Dirty or Clogged Filters: A common but often overlooked cause of rising energy bills is a dirty air filter. When the filter becomes clogged with dust and debris, it restricts airflow, forcing your furnace to work harder and longer to heat your home. This increases energy consumption, and in severe cases, can lead to overheating and system shutdowns. Replacing or cleaning your filter regularly can help your furnace run more efficiently and keep your energy costs down.

Routine furnace maintenance ensures your system operates efficiently, which helps reduce energy bills. Economy Heating & Air offers professional tune-ups to keep your furnace in top condition and improve energy efficiency, saving you money in the long run.

Frequent Cycling

Frequent cycling occurs when your furnace turns on and off more often than it should. While it may not seem like a major issue at first, frequent cycling can significantly reduce your system’s efficiency, increase wear and tear, and lead to higher energy bills. Here’s why this happens and how it impacts your system:

• Thermostat Problems: A thermostat issue is one of the most common causes of frequent cycling. If your thermostat is malfunctioning, it may inaccurately read the temperature in your home and cause the furnace to turn on and off too frequently. This can happen if the thermostat is placed near a heat source, such as a window or an appliance, causing it to think the house is warmer than it is. Recalibrating the thermostat or upgrading to a smart thermostat can help resolve this issue.

• Dirty or Clogged Air Filters: A clogged air filter can also cause frequent cycling. When the filter is dirty, it restricts airflow to the furnace, causing the system to overheat. As a safety measure, the furnace will shut down to cool off, only to turn back on once it has cooled. This cycle repeats, leading to inefficient operation and unnecessary stress on the system. Regularly replacing your air filters can help prevent this problem and ensure smooth operation.

• Oversized Furnace: If your furnace is too large for your home, it can heat the space too quickly, causing it to shut off before completing a full heating cycle. This short cycling results in the furnace turning on and off frequently. While an oversized furnace may seem like a good idea for fast heating, it’s actually inefficient because it doesn’t run long enough to distribute heat evenly throughout the home. Additionally, the constant on-off cycle puts extra strain on the furnace’s components, shortening its lifespan. The best solution in this case is to have an Economy Heating & Air professional assess your furnace and determine if it’s the right size for your home’s needs.

Frequent cycling puts extra strain on your system and shortens its lifespan. Getting this issue checked by the experts at Economy Heating & Air can prevent further damage.

Yellow Pilot Light

The color of your pilot light is a key indicator of your furnace’s health. A blue flame indicates everything is working correctly, while a yellow flame could signal a serious issue like carbon monoxide buildup.

• A yellow pilot light often indicates that the gas is not fully combusting, which can lead to the production of carbon monoxide (CO), a dangerous and potentially deadly gas. This incomplete combustion occurs when there’s a lack of sufficient oxygen, often due to poor ventilation. If the furnace is not venting properly, carbon monoxide can build up inside the furnace and possibly leak into your home. CO is odorless and colorless, making it especially dangerous since it can accumulate without any obvious signs until symptoms like headaches, dizziness, or nausea appear.

• A common cause of a yellow pilot light is dirty burners. Over time, dust, debris, or soot can accumulate on the burners, preventing the proper mix of gas and air needed for clean combustion. This can cause the gas to burn improperly, producing the yellow flame. Dirty burners not only reduce your furnace’s efficiency but also increase the risk of carbon monoxide production. Cleaning the burners as part of regular maintenance can help ensure that your furnace runs safely.

A yellow flame is a serious safety concern, so if you notice this, turn off your furnace and call for a professional inspection right away. The team at Economy Heating & Air is experienced in furnace repairs that keep your system safe and running efficiently.
