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.

We had Rob from Guthrie & Sons come out to repair one of our A/C units. Rob was very friendly and professional. Rob resolved the problem quickly.
As far as price goes, I paid a higher flat fee 12 years ago from one of the larger local companies. I'm very impressed with pricing and quality of work.

I highly recommend Guthrie & Sons and Rob.

Guthrie & Sons has always been super professional and knowledgeable about our system. They did the install a few years ago and have continued to maintain it for us. This year we noticed that our system wasn't performing as well, so when Wayne came out, he noticed a likely leak and was back 2 days later to find and fix it. He was quick, professional, and just extremely nice! 100% recommend.

Called one of the "big guys" in town and the estimate to do what needed to be done to diagnose my problem was nearly 1/2 the cost of the system when I purchased it and had it installed 5.5 years ago, I found Guthrie & Sons and they came out the same day and did the same work for 1/4 the price I was quoted for the same exact work! Daniel was friendly, honest and quickly got my system working as expected. I even purchased the service plan so I don't have future problems. I highly recommend these guys, they were awesome, don't get ripped off call Guthrie & Sons!!!

Matt and Bryan are truly the A-Team! Their teamwork was outstanding and the workmanship was meticulous. The air handler was carefully installed, wiring neatly secured, plenum perfectly fitted, and the condenser precisely positioned and leveled for proper clearance and vibration control. The line set was pressure-tested and vacuumed as well. They also left the work area clean and neat.

Please congratulate them for a job well done!

After dealing with several HVAC companies, Guthrie & Sons clearly stood out as the most ethical, honest, and reliable. From the very beginning, their approach felt transparent and genuinely focused on what was best for us—not on upselling or unnecessary replacements.

We worked with Vlad T., who had previously been out to our home and saved us tens of thousands of dollars by getting our existing AC unit up and running when other companies were pushing for a full replacement. That experience alone earned our trust.

Now that we’re finally ready to purchase new units, there was no question that Guthrie & Sons was the only company we would consider, and Vlad was the obvious choice. He was extremely professional, punctual, and exceptionally knowledgeable, taking the time to explain options clearly and thoroughly. His expertise and honesty made the entire process straightforward and stress-free.

If you’re looking for an HVAC company you can truly trust—one that values integrity, quality workmanship, and customer service—I cannot recommend Guthrie & Sons and Vlad T. highly enough. This is how service should be done.

The layout of my condo made installing splits challenging, and before I met with Guthrie and Sons, three companies either told me that it couldn't be done. Vlad studied my apartment until he found a way to install with minimal openings in the walls and without a second condenser. Mallory, who works in the office, always followed through and advised me when I ran into a hiccup and needed detailed plans for the city. My HOA appreciated Guthrie and Sons' thoroughness and was so impressed with the design, that another resident who had been wanting splits for years, decided to install splits at the same time. The team that came in was knowledgeable, professional, and hard working. They finished a day ahead of time. I'm thrilled with the way everything looks and works.

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 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 bought our HVAC system from Guthrie & Sons. They have been monitoring our system online and later noticed a heat sensor issue.

Zach M. came by and installed on new one. He was extremely professional and completed the installation promptly.

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