When your furnace malfunctions, it can disrupt your home’s comfort and pose serious safety risks. At Affordable Heating & Air Conditioning, Inc., we bring our trusted expertise to diagnose and repair furnace issues efficiently. Here are the most common furnace repair problems that require a professional touch.

1. Ignition System Failures
A properly functioning ignition system is essential for your furnace to generate heat. When issues arise, professional repair is necessary to prevent safety hazards and restore efficient operation.
Faulty Pilot Light
A malfunctioning pilot light can result from gas supply issues, thermocouple failure, or debris buildup. While relighting it might seem simple, an expert can ensure there are no underlying gas line problems.
Broken Hot Surface Ignitor
The hot surface ignitor plays a crucial role in igniting the burners. If it’s cracked or faulty, your furnace won’t produce heat. Attempting a DIY replacement can lead to electrical hazards, making professional service the safest choice.
Malfunctioning Electronic Ignition
Modern furnaces use electronic ignition systems, which can fail due to thermostat malfunctions or power supply disruptions. Our technicians diagnose and repair these issues, ensuring proper ignition and furnace safety.
2. Heat Exchanger Issues
The heat exchanger transfers heat from the burners to the air in your home. If damaged, it can pose serious safety risks, including carbon monoxide leaks.
Cracked Heat Exchanger
A cracked heat exchanger allows dangerous gases to escape into your home. If you notice strange odors or soot buildup around your furnace, shut it off immediately and call a professional for an inspection.
Overheating Problems
Restricted airflow due to clogged filters or blower malfunctions can cause the heat exchanger to overheat, leading to damage. Routine maintenance from a professional ensures your system runs efficiently and safely.
3. Electrical and Control System Problems
Electrical issues can cause complete system failure. Addressing these problems quickly prevents long-term damage and costly repairs.
Circuit Board Failures
The circuit board controls all furnace operations. If it malfunctions, you may experience frequent system shutdowns or no heat output. Professional diagnosis is essential for pinpointing and fixing the issue.
Faulty Thermostat
A malfunctioning thermostat can disrupt heating cycles. While battery replacement might fix minor issues, deeper problems like wiring faults require expert repair to ensure accurate temperature control.
4. Blower Motor Malfunctions
The blower motor distributes warm air throughout your home. When it fails, heating efficiency drops significantly.
Broken Blower Motor
Grinding or squealing noises often indicate blower motor issues. Shutting down the furnace and calling a technician can prevent further damage.
Blower Belt Issues
A worn or misaligned blower belt can cause airflow problems and unnecessary strain on the system. Our team can quickly replace or adjust the belt to restore proper function.
5. Gas Valve and Pressure Switch Problems
Gas-related components regulate fuel flow and ensure safe furnace operation. Faulty components can lead to inefficient heating and safety concerns.
Stuck or Closed Gas Valve
If the gas valve is stuck, your furnace won’t receive the fuel it needs. A professional can safely address the issue, minimizing risks and restoring proper function.
Faulty Pressure Switch
The pressure switch ensures proper venting of gases. If it malfunctions, your furnace may shut down unexpectedly. Professional inspection is necessary to resolve pressure switch issues safely.
6. Flame Sensor Issues
The flame sensor detects the burner flame to ensure safe operation. A dirty or faulty sensor can cause intermittent heating failures.
Dirty or Faulty Flame Sensor
A dirty sensor can cause the furnace to short-cycle, increasing energy costs. Professional cleaning or replacement ensures consistent heating and safe operation.
7. Ductwork and Ventilation Problems
Proper airflow is crucial for furnace efficiency. Blockages or leaks in your duct system can reduce performance and increase energy bills.
Leaky or Blocked Ducts
Leaks in ductwork reduce heating efficiency and compromise air quality. Our technicians can seal leaks and remove blockages to optimize airflow.
Improper Ventilation Setup
Improper ventilation can lead to dangerous gas buildup. Professional installation and regular inspections ensure your system is safe and efficient.
