Common Heating Problems and How We Fix Them

Common Heating Problems and How We Fix Them

At Guthrie & Sons, our San Diego heating repair services cover all makes and models of furnaces and heat pumps, including popular names like Daikin, Trane, Carrier, and Lennox.

Homes in San Diego come in all shapes and ages—from 1940s Craftsman bungalows and postwar ranch homes to coastal condos, Spanish Revivals, and new ADUs. Our technicians are familiar with each type of property and understand the heating problems that you’re going through.

Here are some of the most common heating issues we see in San Diego homes and how we solve them:

When your heater won’t start, the issue could stem from a faulty thermostat, tripped circuit breaker, or safety switch lockout. Sometimes the system isn’t receiving power, or a control board has failed. We run a full diagnostic to confirm where the breakdown is happening, repair or replace the faulty part, and make sure your system safely powers back on.

If your system is running but only blowing cool air, that usually means there’s a problem with ignition, airflow, or the heating elements. Low refrigerant or a malfunctioning sensor can also stop the unit from producing heat. Our technicians test the heating cycle, inspect components, and restore proper temperature output.

Frequent cycling can indicate a dirty air filter, incorrect thermostat calibration, or internal safety sensor issues. This shortens system lifespan and wastes energy. We identify the root cause—whether electrical, mechanical, or airflow-related—and adjust or replace what’s needed to stabilize its performance.

Grinding, rattling, or banging sounds usually signal loose parts, worn bearings, or airflow obstructions. Ignoring noise can lead to serious mechanical failure. We inspect all moving components, tighten or replace worn parts, and make sure your system runs quietly and smoothly again.

If one part of your home stays warm while another stays cold, airflow restrictions or duct issues may be to blame. Clogged filters, blower motor problems, or leaky ductwork can all reduce circulation. We test air pressure, clean and inspect ducts, and ensure balanced airflow throughout the space.

A noticeable rise in energy use without changing your thermostat settings means your system is running inefficiently. This could be caused by dirty components, restricted airflow, or electrical faults. We perform an efficiency check, clean internal parts, and repair damaged components to help your system run efficiently again.

At Guthrie & Sons, we’re your trusted San Diego HVAC contractor for any HVAC repair need, whether it’s for your heating or air conditioning system. You can call us for an air conditioning repair, too, or get a solar system set up to take advantage of all that sunshine.

Many Repairs Can Be Avoided With Our Heating Maintenance Services

Many Repairs Can Be Avoided With Our Heating Maintenance Services

Heating repairs are a normal part of owning a system—but frequent or costly repairs usually mean maintenance has been skipped. Over time, dust builds up, parts loosen, and electrical components wear down from sitting unused most of the year. Without upkeep, even a newer system can start struggling, leading to uneven heating, higher energy bills, and early breakdowns.

That’s why heaters need regular maintenance. Annual tune-ups catch small issues before they turn into expensive problems and keep your system running efficiently. Our heating maintenance services make it simple to stay on top of care for your furnace, heat pump, or mini split.

For an even easier option, join our USA Membership Plan. You’ll get automatic reminders, priority scheduling, and member-only perks like discounted repairs and lower service fees—all designed to save you time, stress, and money. Plus, regular maintenance keeps your HVAC warranty valid and helps your system last years longer. Replacing a heater early can cost thousands—a tune-up is just smart protection that pays off season after season. Talk to our team about signing up!

Frequently Asked Questions

In most cases, repairs are more affordable in the short term—especially if your system is under 10 years old and the issue is minor, like a faulty sensor or ignitor. However, when a heater is 12–15 years old, parts become harder to find and efficiency drops. If repair costs approach half the price of a new system, replacement often saves money long-term through lower energy bills and fewer breakdowns. At Guthrie & Sons, we’ll walk you through both options so you can choose what truly makes sense for your home.

The most expensive repairs usually involve major internal parts such as the heat exchanger, blower motor, or control board. A cracked heat exchanger, for example, can cause safety issues and often signals the end of a system’s life. These parts are labor-intensive to replace and can cost several hundred to over a thousand dollars, depending on the unit. Guthrie & Sons always provides upfront estimates and honest advice about whether repair or replacement is the better long-term investment.

Most heating repairs take two to four hours to complete, depending on what needs to be done and whether parts are readily available. Simple repairs like thermostat recalibration or sensor replacement can be finished the same day, while more complex repairs involving motors or electrical components may take longer. Guthrie & Sons offers same-day San Diego heating repair whenever possible, so you’re not left in the cold for long.

Homeowners insurance typically doesn’t cover repairs from wear and tear, age, or poor maintenance. However, if your heating system was damaged by a covered event—such as fire, lightning, flooding, or vandalism—your policy may help with repair or replacement costs. If you have a home warranty, some plans also include HVAC coverage. Guthrie & Sons can provide detailed documentation and diagnostic reports to support your claim if you’re eligible for reimbursement.

The average heating system lasts 12–20 years, depending on the brand, usage, and maintenance history. In coastal areas like San Diego, salt air and humidity can shorten lifespan slightly if systems aren’t serviced regularly. With annual maintenance, proper filter changes, and timely repairs, many systems reach or even exceed the 20-year mark. Guthrie & Sons offers maintenance plans designed to extend the life of your furnace or heat pump and keep it running efficiently year after year.

I’ve been using Guthrie & Sons for over 15 years. They installed my whole AC system and maintained it all those years and never had an issue. Well it was time for an upgrade and they’ve recently installed my second system. The team 15 years ago and the team this time around were both amazing, professional and clean. I can’t recommend them enough Matt, Ben, Christian and Bryan get 10 stars. They are a bit pricier but worth the investment when you have peace of mind and almost two decades of great service and no issues.

I had an excellent experience with Guthrie & Son AC & Heater Company. Their customer service was outstanding, and they took the time to answer all my questions thoroughly. Every technician who has worked on my AC/heater installation and now the ongoing service has been knowledgeable, respectful, and always on time. I highly recommend them to anyone in need of HVAC services!
I only wish the annual service was cheaper 🙂

I have a maintenance plan for my heat pump and air conditioner which Guthrie & Sons installed two years ago. I am very happy with my system as well as the maintenance plan. Wayne, one of their excellent technicians, just completed the Fall service and now the system is ready for winter use. He is knowledgeable and has been able to answer any questions I have about my system. In addition, the office at Guthrie & Sons is very responsive and follows through on any questions and concerns within 24 hours if not immediately. Great service from a great company.

We needed a new A/C and furnace system. Vlad came by to listen and assess our needs, recommend our new Daikin, and put forth our best estimate.

Carson C. and Michael J. came by to install our unit. They were on time, extremely professional and worked diligently to complete everything. They listened to our needs throughout and made adjustments to our specifications. Carson did not leave until we were totally happy with our unit.

This was a great experience all around and I gladly recommend Guthrie and Son's for all your HVAC needs.

We recently had our A/C replaced by Guthrie & Sons, and I cannot recommend them highly enough. After getting five different bids, Guthrie & Sons stood out immediately—not just on price, but on expertise and professionalism. They even brought their engineers out to ensure the work could be done the right way, which gave us tremendous peace of mind.

From start to finish, their team was outstanding. They worked incredibly hard, treated our home with respect, and left everything spotless—truly the cleanest job site I’ve ever seen after a major project. The installation itself was seamless, and the quality of their work shows in every detail.

If you’re looking for a company that combines deep knowledge, excellent craftsmanship, and genuine care for their customers, Guthrie & Sons is it. Absolutely five stars across the board!

We had a wonderful experience with Guthrie and Sons. Anthony was our estimator and he did a very thorough job of explaining all of our options! Matthew, Bryan, and Isaiah were our installers and they were very efficient, capable, and personable. Our home did not have an existing HVAC system so they had to build the whole thing in an older house that had undergone several additions. We were up and running in just three days. They left the worksite clean at the end of each day. We highly recommend Guthrie and Sons!

Kareen did an outstanding job with our HVAC system. From start to finish, he demonstrated professionalism, patience, and a strong commitment to getting the job done right. Even when faced with several unexpected challenges, he handled each one with skill and determination, never compromising on the quality of his work.

What really stood out was his problem-solving ability and willingness to go the extra mile to ensure everything was operating as it should. He communicated clearly throughout the process, kept us updated, and made sure we felt confident in the work being done.

It’s not often you come across someone who combines technical expertise with such a strong work ethic and positive attitude. We’re very grateful for his efforts and would highly recommend Kareen to anyone needing reliable HVAC service.

Professional from beginning to end

Vlad came out to provide an estimate and was able to size an HVAC system that worked well for my house.

They installed it quickly, without issue and helped me set up an app on my phone to control.

The system is working great to heat and cool my house and is whisper quiet.

Highly recommend going with Guthrie and Sons if you want a high quality experience for large and important purchases.

Our two old furnaces needed replacing and so we contacted Guthrie & Sons because of their good reputation. They sent Zach the next morning. He quickly verified that our two furnaces were beyond repair and Guthrie could supply and install suitable replacement funaces. He also suggested and explained alternative solutions, but we eventually decided to go ahead with furnace replacement. As soon as we notified Guthrie & Sons of our decision they arranged for Cristian and Pablo to come to our house the next day. They did a good job, explained clearly how to operate the new furnaces and thermostats, and were respectful of our house.

Daniel was quick and professional. Fixed our AC problem in an hour and the price was very transparent and beyond fair. Didn’t push the subscription maintenance service, simply said it would be a good idea due to the age of our unit. Highly recommend!

We had to replace a thermostat that had gone bad. In the old days, I could do it myself. Now, though, the programming of the thing requires technical knowledge that I don’t have. The Guthrie guy that did the job was courteous, professional, and as fast as anyone could be. This has been our experience with Guthrie & Sons for every repair, retrofitting, and equipment replacement that they’ve done for us over quite a number of years now.

Carson Snyder and co-worker (Pablo?) did a great job on the installation of the mini-split cassette. They're hard working, they clearly knew what they were doing, polite, cleaned up afterwards, true professionals. I'd gladly recommend these two gentlemen. However, the Company was not good at keeping me informed although I mentioned to the salesman up front that I was information driven. They were short on details and communicated seldom. Anthony did tell me about the government program available that reduced my cost. I wouldn't have known about it if he didn't mention it. The City did approve their work and signed off on the permit which is an indication of the job done right. I think the Company can improve their customer service

Very pleased with the service we received from Guthrie & Sons! Our AC system needed to be replaced after a huge leak. The tech that came out for diagnosis, Mario, took the time to explain the issue to us, as well as our options for repair. They came out on a Saturday to diagnose and it was fixed the following Tuesday. Matthew was the worker that completed the repair and he did an excellent job. Pricing was reasonable. Much more reasonable than the first company we had come out to take a look. We upgraded our system and our SDG&E bill has already gone down. Highly recommend!

We had Guthrie and Sons replace our 50 year old house heater with a heat pump. We are very satisfied with the installation performed by Matthew and Andriy. We were impressed with the detail of their work. They paid particular attention to the required sealing and insulating of the system. Even the HERS testing inspector was impressed with their work. We were also impressed by their professionalism and honesty. They gave us an unexpected partial refund off our signed contract.

We were incredibly impressed with the prompt and professional service! We called on a Saturday morning, and within just a few hours, a technician was at our home. With the recent heat, getting our AC back up and running was a top priority—and they delivered! Mario clearly explained our options and provided a hassle-free solution that was both quick and effective. The repair was completed shortly after we gave the go-ahead. We’ll absolutely be using them again for any future HVAC needs. Highly recommend this company for their affordability, efficiency, and friendly service—we’re already telling our family and friends!
