5 Common Furnace Problems and Their Solutions

1. Problem: No Heat or Insufficient Heat

Cause: A lack of heat or insufficient heat can often be attributed to a malfunctioning thermostat, dirty air filter, or issues with the pilot light or ignition system.

Solution: Start by ensuring that the thermostat is set correctly and is functioning properly. Replace the batteries if needed and clean the thermostat’s internal components. Additionally, inspect the air filter and replace it if it’s dirty or clogged. If the pilot light or ignition system is the issue, it is best to call our professional technicians at Fix It 24/7 Air Conditioning to diagnose and resolve the problem safely.

2. Problem: Frequent Cycling On and Off

Cause: A furnace that frequently cycles on and off may be due to a restricted airflow, a dirty filter, or an improperly sized furnace.

Solution: Examine the air filter and replace it if necessary to ensure proper airflow. If the problem persists, it could indicate that the furnace is improperly sized for your home, which would require professional evaluation and potentially replacing the furnace with one that’s properly sized.

3. Problem: Unusual Noises

Cause: Strange noises coming from your furnace can be caused by a variety of factors, including loose or worn parts, issues with the blower motor, or problems with the ignition system.

Solution: Begin by inspecting the furnace for any loose or worn components and tighten or replace them as needed. If the issue is with the blower motor, a professional technician can lubricate the motor or replace damaged parts. Should the ignition system be the cause, it’s crucial to seek professional help for a safe and effective solution.

4. Problem: Constantly Running Blower Motor

Cause: A blower motor that runs continuously may be caused by a faulty thermostat setting, issues with the blower motor itself, or problems with the limit switch.

Solution: Check the thermostat settings to ensure it is not set to ‘continuous fan.’ If the blower motor itself is the problem, consult a professional technician to diagnose and repair the issue. For a malfunctioning limit switch, it’s essential to have an expert replace the switch to restore proper blower motor function.

5. Problem: Uneven Heating

Cause: Some rooms in your home may be colder than others due to an imbalanced HVAC system, dirty air filter, or issues with your ductwork.

Solution: Begin by checking the airflow at each vent and adjusting the dampers within the duct system as necessary to balance the airflow. Clean or replace the air filter to ensure adequate airflow throughout the home. If the issue persists, consult a professional technician to inspect your ductwork for possible obstructions, leaks, or damage.

Preventative Furnace Maintenance for Longevity and Efficiency

To avoid common furnace issues and ensure your heating system continues to operate efficiently, it’s essential to implement a routine maintenance schedule. Regular furnace maintenance should include the following tasks:

  1. Replace air filters every 1-3 months or according to the manufacturer’s recommendations. A clean air filter ensures proper airflow, maximizes efficiency and improves indoor air quality.
  2. Schedule an annual professional furnace inspection and tune-up. This service will typically include a thorough cleaning of the furnace, inspection of the heat exchanger and other components, as well as testing and calibration of the thermostat, safety controls, and ignition system.
  3. Keep the furnace area clean and free of clutter. This promotes proper airflow, reduces the risk of fire hazards, and allows for easier access to the system during maintenance or repairs.
  4. Inspect your ductwork regularly for obstructions, leaks, and damage. By addressing duct issues early on, you can prevent uneven heating and maintain energy efficiency.

The Importance of Hiring Professional Furnace Technicians

While there are some minor furnace maintenance tasks that homeowners can perform themselves, it’s essential to hire a professional HVAC technician for more complex issues, inspections, and repairs. Furnaces involve a combination of electrical and gas components, which can be dangerous when handled improperly. By partnering with Fix It 24/7 Air Conditioning, a reputable HVAC company, homeowners can feel confident that their furnace is being serviced safely, effectively, and in line with industry best practices.
