Furnace Repair vs. Replacement: Making the Right Choice

Several factors must be considered when deciding to repair or replace your furnace. These details include the age of the equipment, its current condition, energy efficiency, and the cost of repairs versus a replacement unit. If your heating system constantly needs servicing, it is time to consider a new unit, as repairs can be costly and may only temporarily fix underlying issues. If your furnace is between 15 to 20 years old and the cost of repairs is approaching half the price of a new furnace, replacing it might be a better return on investment.

The Benefits of Replacing an Older Furnace

Replacing an old or frequently repaired furnace can offer significant energy savings. In fact, all the energy efficient central heating systems we have replaced in the greater San Ramon area have reduced their power bills by up to 20%. Besides the financial benefits, upgrading your furnace can reduce environmental impact and provide consistent, reliable heating.

Signs that Indicate Your Furnace Needs Servicing

It is always a good practice to watch for any signs of wear and tear in your furnace, as it can help you identify and address issues early on. By doing so, you can make sure that your furnace operates smoothly and safely, saving you from any unwanted repair costs and helping you extend your furnace's life.

Understanding Normal Furnace Sounds

Thermostat Clicking: This sound is normal and indicates the thermostat is working correctly, signaling the furnace to start or stop heating.
Burner Clicking at Start:
Another typical sound at the beginning of a heating cycle, indicating the ignition process is initiating.
Consistent Hum: A steady hum during operation is normal, suggesting the furnace runs smoothly.

Warning Sounds Indicating Issues

Grinding Sounds: May suggest worn blower bearings. Regular maintenance can often prevent this issue.
Repetitive Clicking at Startup: This could signal problems with the flame sensor, ignitor, or gas valve, requiring professional attention.
Loud Bang: Often indicates delayed ignition, possibly due to dirt buildup. This situation may necessitate professional cleaning.
Squealing Noises: These sounds might occur if the blower belt slips or is damaged, indicating needing a check-up or replacement.

Other Signs of Potential Problems

Short Cycling: If you notice that your furnace is heating your home for less than 10-15 minutes or it starts up and then turns off, it could be experiencing short cycling. The most common cause is a faulty flame sensor or ignition. Still, there are other less common issues, such as problems with air filters, the limit switch, thermostat miscommunications, or, in some cases, a bad gas valve.

For those interested in doing their own repairs, we have a detailed DIY guide on resolving short cycling in your furnace by cleaning the flame sensor. You can access the step-by-step instructions with images on our DIY Short Cycling Page to help you save money on a service call. Remember to follow safety precautions and call us if you encounter any problems.

Preventive Measures and Maintenance Tips

To avoid these issues and make sure your furnace operates efficiently, consider the following maintenance tips:
Regular Filter Changes: A simple yet effective way to maintain your furnace's efficiency and prevent many common problems.
Annual Inspections: Arranging for professional evaluations of your furnace each year is crucial for identifying and mitigating minor issues before they develop into significant, costly repairs.
Keeping Vents Clear: Ensure that furniture or other objects do not block vents to maintain proper airflow.

The Importance of Regular Maintenance

Being attentive to the sounds your furnace makes and understanding what they signify can help you identify when it's time for servicing. Regular maintenance, including professional inspections and simple tasks like changing filters, plays a role in preventing issues and extending the life of your furnace.

Satisfied Customer Experiences.
"Pat, the service technician, provided us with excellent service. We had issues with our furnace, and he promptly came to our rescue. Pat diagnosed the problem on the first visit and narrowed the cause to two parts on the heat pump he could acquire under the original manufacturer's warranty. When he got the parts, he called, letting us know he was on his way to complete the repair. The furnace has been operating flawlessly since."

Genuine Reviews from Happy Customers
"We had plans to replace our older furnace, but when the blower motor stopped working, which caused the AC to stop working, we had to replace it sooner than expected. Pat from AC Repair San Ramon installed our new furnace within two days. Even though Pat was willing to come out the same day, our schedule did not allow it. I made an excellent decision to use Pat, who was very knowledgeable and friendly, and I will recommend his services to others."

Frequently asked questions

  • What should I check if my furnace isn't working?
    First, ensure power is on. Then, check if your pilot light is lit or the circuit breaker has tripped. If those are fine, you should schedule a service call.
  • How much does it cost to have my furnace inspected?
    Our standard diagnostic furnace checkup is $95, which includes troubleshooting and identifying any issues needing repair.
  • What are some common furnace failures?
    Frequent problems include clogged filters lowering airflow, faulty ignitors or thermocouples, broken blower motors, leaky ducts losing heat, and worn-out parts like belts or blowers.
  • Will my homeowner's insurance cover furnace repairs?
    Damage-related fixes may be covered. We provide the details necessary for insurance claims free of charge.
  • How do I know if my furnace needs replacing versus repairing?
    If your system starts making loud, abnormal noises like rattling, buzzing or humming, it's likely due to cracks, leaks or other structural damage - a sign replacement is needed. Similarly, any visible signs of rusting or cracking on or around the furnace unit itself mean it's time to replace the system.
