Family-Owned and Operated Since 2005
Guthrie & Sons was founded in 2005 by Wes Guthrie. Built on old-school morals and family values, Wes believed in treating each customer like family and always doing right by the customer. The company has since been passed down to the second generation–Matt and Ben Guthrie. Continuing their father’s legacy, Matt and Ben lead a fantastic team of people who provide San Diego County and beyond with the same level of integrity and care.
We Install and Service Ductless Mini Splits
Many homes in San Diego don't have central air conditioning. And for those that do, not every room is connected to it, and some spaces just stay warmer than the rest of the house. A ductless mini-split is an excellent way to add AC (and heat!) exactly where you need it. We install ductless mini split systems and service them, too. Ask for a quote today!

OUR REVIEWS
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.
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.
Christian and his crew did a great job on the install everything was smooth from start to finish.
I would definitely recommend this company here in Murrieta.
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 🙂
