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.

I have been in the construction industry in San Diego for over 50 years. I owned my own contracting company for over 40 years. I have seen all levels of customer service in my years. The level of customer service from Guthrie and Son’s is among the best I’ve ever seen and received. Every time I hear anyone asking for a referral for HVAC work I immediately give them your number. When I recommend a company I in essence am putting my name and reputation on the line. I refer them with 100% confidence in the service they will receive. Thank you very much for your legendary service.

We first hired Guthrie and Sons to replace a furnace after comparing proposals from several heating and air companies. They’ve since been back for annual check ups, and today Kareen came to diagnose and resolve an issue with our mini-splits. My experience each time, including today, is that they hire friendly, knowledgeable people who do good work. They’ve never tried to upsell or do anything unnecessary, which is the way it should be. I’d recommend them to anyone who asks.

My AC was not working for seven months. Three other companies tried to fix it with no success. Don’t make the same mistake I did—go straight to Guthrie & Sons! They are absolutely worth every penny.

Jonathon is a great technician. He is very willing to answer any questions and explains things very well. He is very transparent with letting us know cost, finance options, different furnace models and anything else we want to know. I would highly recommend him to anyone looking for furnace repair or replacement.

Guthrie and Sons took on the challenging project of installing an HVAC system at St. George's Serbian Orthodox Church of San Diego, CA. They were the only company among the six we consulted that saw the project through to the end. The members of our congregation are not just happy, but thoroughly satisfied with the heating and air conditioning. The system, split units/floor units with condensers outside, was installed with minimal intrusion onto the church's artwork. Despite the project taking longer than expected due to permit delays, the results were well worth the wait. We highly recommend Guthrie and Sons Heating and Air.

Have been using Guthrie & Sons for several years now and purchase my new HVAC system with them. They do our yearly maintenance and have always been professional, efficient and reliable. Jonathan was the tech that came today and I want to thank him for his great work and great attitude.

Got recommended this company by my boss who had a whole mini split system installed in his house. Was able to schedule a service appt same week. On morning of service Daniel W. shows up, listens to all of my concerns, and gets right to work. Daniel was able to investigate the problem, took his time making sure he's eliminated all other possible issues before coming up with a recommendation to my original proposal. Fixes up the issue then checks to see if it is working properly. Not only that, he stays with me few more minutes and addresses all the questions I had for him regarding the system, as a whole. Absolutely amazing.I'll be calling back to schedule maintenance services with them going forward. They won me as a customer.

Zach was very knowledgeable and flexible. He did not push us to purchase a new furnace and instead came up with a plant to continue monitor the furnace and air condition. The inspection was good and he replaced a battery. Looking forward to work with him in the future
