At Guthrie, we have decades of experience under our belt and a commitment to our customers – delivering 5-star service with no upsells, ever.

Family-owned and operated.

Guthrie & Sons Heating, Cooling & Solar was founded by the first generation, 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 continue to serve the community of San Diego county and beyond with professionalism and top-notch customer service.

Clients do not come first. Employees come first.

“Clients do not come first. Employees come first. If you take care of your employees, they will take care of the clients.”- quote by Richard Branson. Your employees are your most valuable asset, even above customers. At Guthrie, one of our company values is always taking care of our employees. Treating our employees with utmost value, care, and respect allows them to provide the same amount of care and service to our customers.


As a two-generation company, we know a thing or two about treating our customers the right way. From the initial touchpoint with our in-house customer support team, to our field technicians servicing your home, we promise to deliver the 5-star service and professionalism you deserve. 

Transparent and honest pricing.

At Guthrie & Sons, we offer transparent and honest pricing. That means we’ll provide you with a detailed quote before starting any work. We often get asked: Why do you not waive a service call with a repair? The truth is: with our transparent pricing, we refuse to hide this fee into your repair quote. All of our quotes are detailed and itemized for full transparency.

No upsells, ever.

When you need assistance with your heating or air system, our certified technicians will come to your home and provide an evaluation of your system. If your system could use a repair that will enhance the safety and/or performance, we will provide a recommendation. Otherwise, if your system is performing optimally, we’ll let you know! We will not try to sell you on anything you don’t need. That’s the Guthrie promise.

High-quality equipment that won't break the bank.

We offer affordable, high-efficiency, top-of-the-line heating and cooling products to keep your home comfortable year-round. The best part? Our HVAC systems won’t break the bank. Our estimates for new installations are complimentary. Schedule an appointment with us to find an option that fits your home and your budget.

I requested quotes from 4 different businesses and received 4 different strategies on how to install mini split AC systems in our house. Guthrie & Sons Tech Vlad came up with the most logical and smart strategy on how to install the units on our house. It became clear that he is very knowledgeable and puts in actual thought on how to solve this installation. The Technician is highly trained, knowledgeable and has great soft skills. He answered all my questions well. The quote was competitive, however not the cheapest. The competence was far above the competition, hence we went with them. They were respectful with installation and machines have been running great a year later. There are minor issues with the units that are addressed a year later during the annual maintenance visit by another highly skilled Tech Johnatan. Overall, very happy with the performance of the units and the customer service. I recommend this company without a doubt!
