In this blog post, we’ll cover everything you need to know about common furnace repairs, including how to identify them, the repair process, and how to prepare for a furnace repair appointment. 

 Identifying Common Furnace Problems

A furnace is essential to your home’s heating system, especially during the winter months. However, like any other machine, furnaces can develop problems affecting efficiency and reliability. Here are some common furnace problems that you should be aware of:

  1. Dirty Filters: Furnace filters trap dust, dirt, and other debris that can clog the system and reduce efficiency. When these filters become dirty or clogged, they restrict the airflow, causing the furnace to work harder than it should. This can lead to increased energy consumption, decreased heating capacity, and premature wear and tear on the furnace. To avoid this problem, you should change your furnace filters regularly, preferably every 1-3 months.
  1. Thermostat Issues: The thermostat is the device that controls the furnace’s temperature, and if it’s not functioning properly, it can cause the furnace to work erratically or not at all. Some common thermostat issues include faulty wiring, incorrect calibration, and dead batteries. If you suspect your thermostat is the problem, try replacing the batteries or contacting a professional to diagnose and repair the issue.
  1. Ignition Problems: If your furnace isn’t igniting, it won’t be able to produce heat. A faulty pilot light, a dirty burner, or a malfunctioning ignition system can cause this problem. If your furnace isn’t producing heat, it’s best to contact a technician to diagnose and fix the issue.
  1. Noisy Furnace: If your furnace makes strange noises, it could be a sign of a problem. Rattling or banging noises can indicate loose or broken components, while whistling or humming sounds may indicate airflow problems. If you notice any unusual noises from your furnace, you should contact a technician to diagnose and fix the issue.
  1. Poor Airflow: Poor airflow can cause your furnace to work harder than it should, reducing efficiency and increasing energy consumption. Dirty air filters, clogged ducts, or a malfunctioning blower fan can cause this problem. To resolve this issue, check your air filters regularly and contact a technician to inspect your ductwork and blower fan.

Benefits of Professional Furnace Repair Service

If your furnace is not functioning correctly, it can be tempting to try to fix the problem yourself or hire a handyman to do the job. However, opting for professional furnace repair services has numerous benefits, including:

  1. Expertise and Experience: Professional furnace repair technicians have the necessary knowledge and experience to diagnose and fix various furnace problems. They are trained and licensed to work with heating systems and have the expertise and equipment to handle complex repairs safely and effectively.
  1. Safe Repairs: Furnaces can be dangerous, and attempting to fix the problem without the necessary training can put you and your family at risk. Professional furnace repair technicians are trained to work with heating systems safely, minimizing the risk of accidents and ensuring that your furnace is functioning safely.
  1. Efficient Repairs: Professional furnace repair technicians have access to the latest tools and equipment, enabling them to perform repairs efficiently and effectively. They can diagnose and fix the problem quickly, reducing downtime and restoring your furnace’s functionality as soon as possible.
  1. Warranty Coverage: If your furnace is still under warranty, attempting to repair it yourself or hiring a handyman can void the warranty. The manufacturer’s warranty usually covers professional furnace repair services, ensuring that your furnace remains protected.
  1. Cost-Effective: While it may seem like hiring a professional furnace repair service is expensive, it can be more cost-effective in the long run. Experienced technicians can diagnose and fix the problem correctly, minimizing the risk of recurring issues and reducing the need for costly repairs or replacements.
  1. Preventative Maintenance: Professional furnace repair services can also provide preventative maintenance, which can help you avoid expensive repairs and extend your furnace’s lifespan. They can inspect your furnace regularly, clean the system, and make any necessary adjustments to ensure it functions optimally.

Furnace Repair Process

 The first step in the furnace repair process is to perform an initial inspection of the furnace. The technician will examine the furnace’s components, such as the blower motor, igniter, burner, and thermostat, to determine the source of the problem. Once the technician has identified the potential problem, they will perform diagnostic tests to verify it. These tests can include checking various furnace components’ voltage, amperage, and resistance.

The technician will develop a repair plan based on the initial inspection and diagnostic tests. The repair plan will outline the necessary repairs, estimate the cost and timeline, and discuss any safety concerns. The technician will then proceed with the repair work, following the repair plan. The repairs can include cleaning or replacing components, rewiring faulty wiring, or replacing damaged parts.

After the repair, the technician will test the furnace to ensure it functions correctly. They will also calibrate the furnace to ensure it produces the correct heat and operates efficiently. Once the furnace is repaired, the technician will perform a final inspection to ensure everything works correctly. They will check for any safety concerns and provide the furnace functions efficiently. After the repair work is completed, the technician will follow up with the customer to ensure that they’re satisfied with the repair work. They will also provide any necessary instructions on operating and maintaining the furnace.


Preparing for a Furnace Repair Appointment

If you have scheduled a furnace repair appointment with a professional technician, there are a few things you can do to prepare for their visit. Here are some tips on how to prepare for a furnace repair appointment:

  1. Clear the area around the furnace, ensuring no objects or obstacles block access to the furnace. This will allow the technician to work more efficiently and minimize the risk of accidents.
  1. Turn off the power to the furnace before the technician arrives. This will ensure that the technician can work safely without electrocution. Locate the furnace’s power switch, which is typically located on or near the furnace.
  1. Have any information ready that the technician may need, such as the furnace’s make and model number, the age of the furnace, and any past repairs or maintenance done on the furnace. This will help the technician diagnose the problem more efficiently and accurately.
  1. Ensure that the technician has easy access to the furnace, such as providing a clear path and unlocking any doors or gates they may need to access the furnace.
  1. Ensure that the work environment is safe for the technician. This means removing pets or children from the area and ensuring the technician has adequate lighting and ventilation.
  1. Be available during the appointment time in case the technician has any questions or needs your input. It’s also helpful to provide the technician with your contact information if they need to reach you after the appointment.
  1. Do not use volatile or flammable products near the furnace while undergoing repair work, as this could cause a fire or explosion.
  1. Also, notify your utility service provider of any furnace repair service call in advance so that they can cover any expenses related to the repair work during an outage.

How to Find a Reliable HVAC Contractor

Finding a reliable HVAC contractor can be daunting, but there are some key factors to consider when searching for the right professional for the job. Here are some steps you can take to find a reliable HVAC contractor:

  • Ensure the HVAC contractor you’re considering is licensed and certified to work in your area. This ensures that the contractor meets the necessary qualifications and standards for HVAC work.
  • Look for an HVAC contractor who has been in business for several years and has a proven track record of success. Ask for references and read reviews from past customers to get an idea of the contractor’s experience and reputation.
  • Ensure that the HVAC contractor you’re considering has liability insurance and bonding. This protects you in case of any accidents or damages that may occur during the HVAC work.
  • Look for an HVAC contractor with the proper equipment and tools to perform the job. This ensures that the work will be done efficiently and effectively.
  • Request multiple quotes from different HVAC contractors to compare pricing and services. Be wary of contractors who provide significantly lower quotes than others, which may indicate low-quality work or hidden costs.
  • Look for an HVAC contractor who provides maintenance and follow-up services after installation or repair. This ensures that your HVAC system continues functioning efficiently and helps you avoid future repair costs.
