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!
