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

STEP ONE

DETERMINING SYSTEM SIZE

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.

STEP TWO

SITE SURVEY

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. 

STEP THREE

INSTALLATION PROCESS

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. 

STEP FOUR

FINAL PERMITS AND
APPROVAL TO OPERATE

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.

Having trouble with the remote and to operate our mini split cassette unit. Within 5min Mario had the unit up and running as well as how the unit with remote works efficiently. Mario also went to bat for us to have the condenser mounted on the Guest House rather than in the dirt inches away from our brow ditch.Thanks Mario

Guthrie and Sons installed our heating/AC unit in 2022 and so I called them for their help with an issue I was having. The technician Jonathan came out and checked all of the units (4) and the outside control panel and all is good. We could not replicate the (small) issue and determined it to be an unknown cause. Glad Jonathan came out, all units are now working perfectly. Thank you to Guthrie and Sons!!

I had a really positive experience with Guthrie & Sons. I worked with two techs, Jonathan and Zach, and two people over the phone, Mallory and Makenzie. Jonathan and Zach were super helpful, informative and patient with all of my questions. Mallory and Makenzie were also very helpful, patient and accommodating as they enabled a fix to my heater issue in a timely manner. Would 100% recommend their services!
