Air Conditioning Repair Services That Solve Whatever’s Going On

Homes on the canyon rims feel hotter, and those Santa Ana winds can make you turn up the AC more often. When you need an air conditioner repair in Tierrasanta, San Diego, Guthrie & Sons moves fast to limit the damage and the time you’re without AC. Here’s more on what we’ll do:

You lower the thermostat, wait for that familiar click… and nothing happens. No fan, no hum, no air moving through the vents. This can be caused by a tripped breaker, a failed capacitor, thermostat issues, or a safety switch that shut the system down. We test power, controls, and startup components step by step to find exactly where it’s stopping and get your AC running again safely.

Air is coming out, but it’s not cold—just room temperature or worse. That usually signals low refrigerant, a failing compressor, a dirty outdoor coil, or an issue with the reversing valve on certain systems. We check refrigerant levels, inspect the condenser, and test the cooling cycle to get cold air back instead of warm drafts.

Your system kicks on, runs for a few minutes, then shuts off… only to start again shortly after. This short cycling can be caused by an overheating unit, restricted airflow, a clogged filter, or an oversized system. We look at airflow, coils, sensors, and electrical components to stop the constant cycling and protect the system from further wear.

If your AC suddenly starts banging, screeching, rattling, or buzzing, something inside isn’t happy. Loose fan blades, worn bearings, failing motors, or debris inside the unit are common causes. We find where the sound is coming from and repair or replace the worn part before it turns into a bigger breakdown.

Some rooms feel fine while others stay hot and stuffy, no matter how low you set the thermostat. This often comes down to airflow problems, duct leaks, weak blower motors, or thermostat placement issues. We inspect the full system—including ductwork—to make sure cool air is reaching every part of your home the way it should.

You notice water pooling near the indoor unit or ice forming on the lines outside. A clogged condensate drain, frozen evaporator coil, or refrigerant leak could be behind it. We clear drain lines, repair leaks, recharge refrigerant if needed, and make sure the system is draining and cooling properly so you’re not dealing with more water damage or a reduced performance anymore.

Most of the time, we can repair your AC and give it years of life back. But if your system is 12+ years old, needs a major repair like a compressor, or uses parts that are hard to find, an air conditioning replacement may be recommended or required. You’ll always get expert guidance, clear explanations, and zero pressure from the Guthrie & Sons team. Schedule your Tierrasanta, San Diego, air conditioning repair today so we can see what needs to happen next.

Fewer Breakdowns. Lower Bills. A Smarter Way to Care for Your AC.

Nobody wants to deal with air conditioning repairs multiple times in the same year. If your AC keeps breaking down, it’s usually because the system hasn’t been cleaned, inspected, or tuned up regularly. Small issues—like dirty coils, clogged filters, loose wiring, or low refrigerant—force your system to work harder and wear out faster. Yearly air conditioning maintenance gives us time to clean the system, check refrigerant levels, test electrical components, and catch issues early.

You can always book air conditioning maintenance when it works for you, but many families prefer our USA Membership Plan so they don’t have to think about it. We handle the reminders, schedule your seasonal tune-ups, and give you priority service if something comes up. Members also receive 15% off repairs, reduced service fees, and extended parts and labor coverage. The time savings and long-term cost benefits add up quickly, and we’d love for you to take advantage—talk with our team about signing up.

Frequently Asked Questions

Air conditioning repair costs can vary quite a bit depending on what’s wrong. Smaller fixes—like a capacitor, contactor, or thermostat issue—are usually on the lower end, while major repairs like a compressor or evaporator coil replacement are on the higher end. After we inspect your system, we’ll explain exactly what failed, what it takes to fix it, and give you clear pricing before any work begins.

In many cases, yes. A 10-year-old air conditioner can still have good years left, especially if it’s been maintained and the repair is limited to one component. We’ll look at the overall condition of the system, the cost of the repair, and whether it makes financial sense compared to replacement, then help you make a smart decision.

If your system is still under the manufacturer’s parts warranty—often 10 years if it was registered—some repairs may be partially or fully covered. Labor is usually separate unless you have an extended warranty. We’ll check your model and serial number, confirm warranty status, and let you know exactly what is and isn’t covered.

Yes, we provide same-day emergency AC repairs whenever possible. If your air conditioner stops working during a heat wave or outside normal hours, we’ll do everything we can to get a technician out quickly. With our 24/7 live answering, you won’t be left waiting for a callback when you need help fast.

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!

Guthrie and Sons was very professional and communicative. Matthew and Bryan did incredible work, and followed up with a lot of testing to make sure my new unit was functioning well. They went above and beyond to ensure that things were done correctly. I could tell their standards were extremely high, and I felt relieved seeing how much care they took in their installation. I’m very pleased with the result!

Very helpful, quick and easy to schedule! We had an unexpected (but necessary) repair when doing maintenance and both the office and tech Carson were thorough and transparent in their support. Great service!

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.

This is by far the best company for your HVAC needs. They are honest very caring. Good fair pricing and got the job done efficiently and on time. I also signed up for their bi-yearly service which they performed the winter one and went very well. Thanks

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.

Guthrie & Sons responded immediately to my online request, and was able to send someone out immediately. Zack, our technic-ian was very friendly, professional, knowledgeable and gladly answered all of our questions. He found the problem immediately, and left the work area clean and in good order. We would highly recommend Guthrie & Zack! They are real assets to our community.

I've been using Guthrie & Sons for over 10 years and two homes. I really like that they are a family-owned and an established business. Always professional, on time, and always quality work. I've used their services from simple routine maintenance to having a new AC installed.I've never had a bad or even mediocre experience; I'm just always overall pleased with their work.

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.

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.

Trae Washburn

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.
