Signs Your Furnace or Heater May Soon Need a Repair

Fortunately, it isn’t hard to tell when your furnace is near due for service and repairs. Your furnace or heater will likely send out signals to alert you that something isn’t right. Here are some signs to look for:

  • Odd noises including hissing or rattling
  • Soot or rust around furnace
  • Blowing mainly cool air
  • Increase in energy bills
  • Failure to turn on
  • Water leaking near furnace
  • Poor air quality

Do I Need a Repair or a Replacement?

  • Your heater is 5 years old. Your heater is newer in age. Consider repairing your system to restore it back to working order.
  • Your heater is 12 years old with no breakdowns. Consider repairing your system to restore it back to working order.
  • Your heater is 12 years old with occasional or multiple breakdowns. Consider repairing your system as a temporary “band-aid” solution. Consider replacing your system as your heater may soon fail entirely.
  • Your heater is 30 years old. Consider replacing your system. A “band-aid” repair may not be possible as it can be hard to find replacement parts for older systems.

When you schedule a heater repair with us, our technicians will conduct a thorough diagnostic evaluation of your heater to troubleshoot the issue. If you are unsure if your heater can be repaired or if you need a replacement, our team of experts is here to help. We’ll provide solutions to fit your family’s needs and budget.

Heating Repair FAQs

We first hired Guthrie and Sons to replace a furnace after comparing proposals from several heating and air companies. They’ve since been back for annual check ups, and today Kareen came to diagnose and resolve an issue with our mini-splits. My experience each time, including today, is that they hire friendly, knowledgeable people who do good work. They’ve never tried to upsell or do anything unnecessary, which is the way it should be. I’d recommend them to anyone who asks.

My AC was not working for seven months. Three other companies tried to fix it with no success. Don’t make the same mistake I did—go straight to Guthrie & Sons! They are absolutely worth every penny.

Jonathon is a great technician. He is very willing to answer any questions and explains things very well. He is very transparent with letting us know cost, finance options, different furnace models and anything else we want to know. I would highly recommend him to anyone looking for furnace repair or replacement.

Guthrie and Sons took on the challenging project of installing an HVAC system at St. George's Serbian Orthodox Church of San Diego, CA. They were the only company among the six we consulted that saw the project through to the end. The members of our congregation are not just happy, but thoroughly satisfied with the heating and air conditioning. The system, split units/floor units with condensers outside, was installed with minimal intrusion onto the church's artwork. Despite the project taking longer than expected due to permit delays, the results were well worth the wait. We highly recommend Guthrie and Sons Heating and Air.

Have been using Guthrie & Sons for several years now and purchase my new HVAC system with them. They do our yearly maintenance and have always been professional, efficient and reliable. Jonathan was the tech that came today and I want to thank him for his great work and great attitude.

Got recommended this company by my boss who had a whole mini split system installed in his house. Was able to schedule a service appt same week. On morning of service Daniel W. shows up, listens to all of my concerns, and gets right to work. Daniel was able to investigate the problem, took his time making sure he's eliminated all other possible issues before coming up with a recommendation to my original proposal. Fixes up the issue then checks to see if it is working properly. Not only that, he stays with me few more minutes and addresses all the questions I had for him regarding the system, as a whole. Absolutely amazing.I'll be calling back to schedule maintenance services with them going forward. They won me as a customer.

Zach was very knowledgeable and flexible. He did not push us to purchase a new furnace and instead came up with a plant to continue monitor the furnace and air condition. The inspection was good and he replaced a battery. Looking forward to work with him in the future
