Take the first step to renewable energy

With utility costs on the rise, more and more San Diego homeowners are turning to renewable energy sources like the sun. If you own your home and plan on living there for at least the next 10 years, and you pay an average of over $100/month in utility bills, you are the perfect candidate for solar. 

Free yourself from being dependent on the utility company and install a new solar system with the experts at Guthrie & Sons Heating, Cooling & Solar. 

Powered by SunPower

Living in Southern California, San Diego has an average of 262 days of sunshine per year. Powering your home with renewable energy is a no-brainer. Guthrie & Sons is proud to partner with SunPower, offering the most innovate and reliable solar power technology. With clean, minimalistic designs and an improved technology, SunPower panels have an extra layer within in the back side of each panel, allowing some of the sun’s light to be reflected back into the solar cell, which helps to generate even more energy.

Our Solar Installation Process



We’ll first ask you to provide us with a copy of your utility bill so we can determine your expected energy usage. We will also ask if you plan on making home improvement upgrades that may affect your usage, such as a new heating and air system or a new EV charger.

The size of your solar system will be determined by your energy usage. We want to be sure to size your system a little more than what your home typically consumes.



After we determine the proper system size for your family’s needs, we will come out and conduct a site survey. During a site survey, we’ll do an inspection of the home, evaluate the layout of the electrical wiring, and determine a plan of action for the installation. 



Depending on the size of your solar system, the installation typically only takes one day. Our certified solar technicians will first start with precisely measuring your roof and installing the racks which the panels will lay on. Next, the electrical wiring will be installed and connected to your electrical panel. Finally, your solar panels will be set into place on the racks. 



After your solar system is installed and before you start reaping the benefits, you must receive your final permit from the county and a final approval from the utility company to operate your system. 

Rest assured, we will take care of the final permitting and approval process with the utility company on your behalf.


EV Charger Installation

With gas prices on the rise, San Diego homeowners are turning to electric cars. Enjoy the convenience of charging your vehicle at home with a residential EV charger. 

Book an appointment for a quote to install your EV charger. 

Battery Back Up

Pair your solar system with a battery back up from Guthrie & Sons. When you have a power outage, your battery back up system allows you to control which appliances you want to remain powered. The next time a storm rolls through, you’ll have peace of mind knowing you can continue powering your appliances.

Rick was very helpful in giving my Tenant and me another tutorial on operating the Thermostat for the Heat Pump. This Tutorial provided some simple yet essential information as to the basics of the thermostat's operating options.Rick was also helpful in advising me that the return vent filter should be changed every six months, as well as getting the measurements of 14" X 24" for the correct size of the filters to purchase.He was courteous, used his shoe covers consistently, and suggested I consider purchasing Guthrie and Sons' Maintenance and Service Plan.I would appreciate details of the cost and benefits of the Plan.My overall message is one of appreciation for such prompt response to my call, next day scheduling, and expert service delivered by rick.KUDOS TO ALL OF YOU AT GUTHRIE AND SONS, and congratulations on your growth and new home for the business.Gene Fischer

Very responsive to my service request. Dave diagnosed the issue quickly and corrected the situation so that the failure will be less likely to happen again. He explained the additional repairs which were necessary. Guthrie ordered the part and quoted the job the following day.

I have been using Guthrie & Sons Heating and Air since I moved to San Diego over 10 years ago now . When I later relocated to the far north county area I was happy they served customers that far away. They’re always on time, professional and reasonable on price. What else could anybody ask for?
