The Guthrie Way
Expert Service With Integrity, Experience, and Family Values
When your name is on the truck, the work means something more. As a family-owned company, we approach every job with a sense of responsibility and pride. We take care of our team, and we take care of our neighbors—we call it doing it The Guthrie Way. Here’s what you can expect when you work with us in La Jolla and other San Diego area neighborhoods:
5-Star Service
We hold ourselves to a higher standard throughout the entire process. You’ll notice it in our clear communication, how we work, and in the reviews our customers leave after the job is done. It’s the kind of experience people expect—and remember.
Honest Pricing
We keep pricing clear and upfront so you’re never left guessing. You can look through our pricing and special offers anytime, and we’ll walk you through everything before we get started. No confusion, no last-minute surprises.
Expert Technicians
Not all technicians bring the same level of experience. Our team is made up of NATE-certified (North American Technician Excellence) technicians who are some of the best in the industry. Everyone on staff is polite and professional.
Family Values
Our company has been family-owned and operated since 2005, and that’s getting harder and harder to find these days. We’re one of the few HVAC companies left with these local roots. We love getting to know our customers better and vice versa.
No Upsells
We’re not here to push anything you don’t need. We offer free estimates and walk you through your options so you can decide what works for you. You’ll get honest input and space to make the right call without pressure.
Protect Your System, Your Home, and Your Money
The easiest way to protect your HVAC system—and your time—is to stay ahead of maintenance rather than wait for something to go wrong. The last thing you want with your busy schedule is a sudden breakdown and a last-minute service call. Staying consistent with your heating and cooling system maintenance keeps things running smoothly, improves energy efficiency, and helps avoid those bigger repairs later.
With our USA Membership Plan, everything is handled for you. We keep your annual maintenance on schedule, prioritize your calls during the peak busy season, and offer exclusive savings on repairs and service fees along the way.

Air Conditioning Services in La Jolla
Living in La Jolla, you get that ocean breeze, but it doesn’t always move through the house the way you want it to. In the summer, homes with more sun exposure or less airflow can warm up by mid to late afternoon. Having a good air conditioner is important, and you need a good air conditioning company to care for it. Guthrie & Sons has all the air conditioning services La Jolla residents need now and later.
Mini Split Services in La Jolla
Ductless mini split systems show up all over La Jolla, especially in guest suites, detached casitas, older coastal homes, and spaces that were added on over time. They’re a great fit for meeting specific cooling needs, like in rooms that get more sun and hold heat into the afternoon. Guthrie & Sons offers a full range of mini split services in La Jolla, including installation, annual tune-ups, and replacement to keep those spaces comfortable.
Heat Pump Services
With California continuing to push away from gas, more La Jolla homeowners are moving toward all-electric systems like heat pumps. They fit well here since you’re not dealing with extreme cold—just cooler mornings, warmer afternoons, and everything in between. One system handles both heating and cooling without much effort. Guthrie & Sons provides heat pump services in La Jolla to help you make that switch and keep it running.
HVAC Services in La Jolla
We offer HVAC services in La Jolla for a wide range of homes, from oceanfront properties and hillside houses to condos, guest homes, and light commercial spaces. Whether you’re near UC San Diego or over in La Jolla Farms or La Jolla Heights, we’ve worked in homes like yours. We also offer financing to make larger projects easier to manage, maintenance plans to stay ahead of wear, and emergency service when you need help now. For the HVAC installation La Jolla residents need, rely on Guthrie & Sons because we’ll get the job done.
Heating Services in La Jolla
La Jolla doesn’t get harsh winters, but you feel the drop in temperature in the mornings and once the sun goes down. Homes here are built to stay open and breezy, which is great during the day but doesn’t hold heat very well. Add in the marine layer and cooler coastal air, and it can get chilly inside pretty quickly. As your La Jolla heating company, we provide heating services for furnaces, heat pumps, and ductless systems so your home stays comfortable when it cools off.
Furnace Services in La Jolla
Furnaces are still part of a lot of La Jolla homes, especially older properties with central systems already in place. They don’t get used much, but when the temperature drops—early mornings, cooler nights, or those gray marine layer days—you expect heat right away. The problem is, systems that sit most of the year don’t always fire up cleanly. Our furnace services in La Jolla are here to keep things reliable or help you figure out the next step if it’s not.
Indoor Air Quality Services in La Jolla
Most La Jolla homes are designed to let air move through, which is great during the day. But with that comes coastal humidity, dust, and particles that don’t always clear out the way you’d expect. You might notice it in rooms that feel a little damp or in how quickly surfaces collect dust. Over time, it adds up inside your system, too. Our indoor air quality services in La Jolla help clear that out and improve how the air moves through your home.
Make La Jolla’s Sunshine Pay Off at Home With a Solar System
La Jolla gets plenty of sun, even if the mornings start off gray. By the time it clears, your home is already starting to warm up and your system is working harder to keep things comfortable. That’s when energy use really picks up. Instead of paying for all of that power, it makes sense to use the sunlight your home is already getting.
Our solar services in La Jolla cover rooftop panels, battery backup, and EV charger setup so more of your home runs on what you generate. It’s a smart way to keep more of your money in your pocket without changing how you live! If you’re interested in a solar installation in La Jolla, just talk to our team.
Upgrade to a Heat Pump Water Heater to Use Less Energy Every Day
In most La Jolla homes, the water heater is one of the biggest energy users. It’s running every day—showers, laundry, dishes—so even small efficiency gains can make a real difference. If you’re looking to lower energy costs, this is one of the best places to start.
Heat pump water heaters work by pulling heat from the air around them and using it to warm your water, instead of generating heat directly like traditional systems. That means they use a lot less electricity to do the same job. You still get the hot water you need, just with less energy going into it. Our heat pump water heater services include installation, maintenance, and repair to keep everything running the way it should. If you’re thinking about installing one or need service for your current system, schedule with us, and we’ll take care of it.
Real Reviews From Real Customers
We do things differently, and our customers appreciate it. See what some of our thousands of satisfied customers have to say about working with us.
Please congratulate them for a job well done!
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.
I only wish the annual service was cheaper 🙂
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.
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!
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.
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.
