7 Common Furnace Problems That Require Immediate Repair

If you’ve ever had your furnace break down in the dead of winter, you know the importance of routine maintenance. However, even with regular check-ups, furnaces can still experience common issues that demand immediate attention. That’s why Sweet Life Heating & Cooling delves into seven of the most prevalent furnace problems that necessitate immediate repair. 

Understanding these issues can help you identify early signs of trouble, ensure your home remains comfortable year-round, and prevent minor issues from escalating into more costly repairs. From a faulty thermostat to an unresponsive pilot light, these issues may seem inconsequential at first but can compromise the efficiency and safety of your heating system.

1. Faulty Ignition System

One common furnace problem requiring immediate attention is a faulty ignition system. This issue can manifest in two ways: either your furnace’s electronic ignition system fails to ignite, or the pilot light will not stay lit on older models with a standing pilot light. A malfunctioning ignition system prevents your furnace from producing heat, leaving you cold during the winter season.

The root cause of this problem can vary. For electronic ignition systems, the hot surface ignitor may need replacement, or the flame sensor could be dirty or malfunctioning. In the case of a standing pilot light, the thermocouple could be faulty, or there might be a gas supply issue. To diagnose and repair such challenges, contact our professional HVAC technicians.

2. Dirty or Clogged Air Filters

A common yet often overlooked issue is dirty or clogged air filters. Neglecting to replace filters regularly can lead to reduced airflow, causing your furnace to work harder and ultimately leading to higher energy bills. In some cases, a severely clogged filter can cause your furnace to overheat and shut down as a safety measure.

To prevent this issue, check your air filters monthly and replace them as needed, typically every one to three months. If you’re unsure which filter suits your furnace, consult with our HVAC professionals to ensure proper compatibility.

3. Inadequate Airflow

Inadequate airflow, often the result of blocked or closed vents, can cause several problems for your furnace. Restricted air circulation can lead to uneven heating throughout your home and place extra strain on your furnace, causing it to overheat or even fail entirely. In some cases, inadequate airflow could be attributed to a malfunctioning blower motor or fan.

Ensure that all your vents and registers are clean, open, and unobstructed to maintain proper airflow. If the issue persists, it’s wise to consult with our HVAC professionals, who can pinpoint the root cause and suggest appropriate repairs.

4. Thermostat Malfunctions

Thermostat issues can make it seem like your furnace is not functioning correctly. When your thermostat sensor is not correctly reading room temperature, it might cause your furnace to shut off prematurely or cycle on and off frequently. Improper calibration and loose wiring connections within the thermostat are common culprits.

Start by checking the thermostat’s batteries and settings, ensuring it is set to ‘heat’ and the temperature is set correctly. If the problem persists, it may be time to call a professional technician who can diagnose the issue or recommend a new thermostat.

5. Noisy Furnace

While all furnaces make some noise during operation, unusual or excessively loud sounds may indicate a problem that needs immediate attention. Banging, grinding, or squealing noises can result from various issues, including loose or damaged components such as belts, bearings, or the blower assembly. If you notice unusual sounds emanating from your furnace, it’s essential to contact our professionals to diagnose and repair the problem promptly.

6. Leaking Water or Gas

If you notice water pooling around your furnace, the cause may be a blocked condensate drain line or a malfunctioning condensate pump in high-efficiency furnaces. Water leaks can cause structural damage to your home, so it’s crucial to address the problem as soon as possible.

Gas leaks, on the other hand, are especially hazardous. If you smell gas or suspect a leak, turn off your furnace immediately, leave the premises, and call your gas company or our HVAC professionals to address the problem. Gas leaks pose a significant risk to your home and family, and they should be treated with the utmost urgency.

7. Failing Blower Motor

Blower motors play a crucial role in distributing warm or cool air throughout your household. Signs of a failing motor may include poor airflow, frequent cycling, or the furnace running continuously without producing heat.

If you suspect a malfunctioning blower motor, it’s essential to consult with our HVAC professionals, as the issue will not resolve itself and may cause further complications. A certified technician can diagnose the problem and determine whether the motor requires repair or replacement.
