• Weak Airflow: A weak blower motor may result in poor airflow, causing uneven heating and reduced comfort.
• Unusual Noises: Squealing or grinding noises can indicate that the blower motor bearings are worn or the belt is loose.
• Overheating: If the motor overheats, it can cause the furnace to shut down. This might be due to a clogged filter, obstructed vents, or a failing motor.

Regular maintenance can help identify and prevent blower motor issues. If you experience any of these problems, it’s essential to call our professionals. They can inspect, repair, or replace the blower motor to ensure efficient operation.

Dirty or Clogged Filters

Dirty or clogged filters are a common issue that can affect the performance of your furnace. Keeping the filters clean is essential for several reasons:

• Reduced Airflow: Clogged filters restrict airflow, making the furnace work harder to heat your home. This can cause the system to overheat and shut down.
• Poor Indoor Air Quality: Dirty filters can circulate dust, allergens, and other contaminants throughout your home, affecting air quality and health.
• Increased Energy Bills: When the furnace has to work harder due to clogged filters, it uses more energy, leading to higher bills.
• Wear and Tear: Restricted airflow can cause components to work harder, leading to increased wear and tear and a shorter lifespan for your furnace.

To prevent these issues, check and replace the filters regularly. Our professionals can recommend the best type of filter for your system and ensure it’s installed correctly.

Pilot Light and Sensor Issues

The pilot light and sensors are crucial components of a gas furnace. When they malfunction, your furnace’s performance can be compromised:

• Pilot Light Issues: A pilot light that goes out frequently can indicate issues with the gas supply, a draft, or a dirty flame sensor.
