Whole-House Generator

What is a Whole-House Generator?

A whole-house generator is a permanently installed standby power system that connects to your home’s electrical panel and is powered by natural gas or propane. Unlike portable generators, which require manual setup and refueling, whole-house generators are designed to turn on automatically when a power outage is detected.

How It Works

  • Automatic Detection – The generator’s transfer switch monitors your home’s power supply.
  • Instant Activation – If the power goes out, the generator automatically starts within seconds.
  • Seamless Power Transfer – The system supplies electricity to your home until the utility power is restored.
  • Automatic Shutdown – Once power returns, the generator shuts off and returns to standby mode.

Whole-house generators provide uninterrupted electricity to essential appliances and devices, ensuring your home remains safe and functional during blackouts.

Whole-House Generator Installation Process

At Mauzy, we provide a comprehensive, hassle-free installation process to ensure your generator is installed safely and operates efficiently.

Step 1: In-Home Consultation & Load Assessment

Our electricians assess your home’s power needs and electrical system to determine the appropriate generator size and capacity. We evaluate:

  • The number of circuits and appliances you need to power
  • Your home’s electrical panel capacity
  • Fuel source availability (natural gas or propane)

Step 2: Selecting the Right Generator

We install top-quality Generac whole-house generators, known for their efficiency, durability, and advanced power management technology. Our team helps you select the ideal model to fit your home’s power requirements and budget.

Step 3: Site Preparation & Permits

We handle all aspects of the installation, including:

  • Choosing a safe installation location for the generator unit
  • Securing necessary permits in compliance with San Diego County codes
  • Preparing the site with a concrete pad and proper ventilation

Step 4: Generator Installation & Electrical Integration

  • The generator is securely installed and connected to your home’s main electrical panel.
  • A transfer switch is installed to automatically switch power between the utility and the generator.
  • The system is wired and tested to ensure seamless operation.

Step 5: Testing & Final Inspection

Before completing the installation, our electricians perform:

  • Comprehensive safety and functionality tests
  • System calibration to ensure optimal performance
  • Final inspection and homeowner training on generator operation and maintenance

Whole-House Generator Installation FAQ

  • Benefits of Installing a Whole-House Generator

    Benefits of Installing a Whole-House Generator

    Uninterrupted Power Supply

    Whole-house generators ensure that your home remains operational even during extended outages. This means no loss of heating, cooling, refrigeration, or security system functionality.

    Automatic Operation

    Unlike portable generators that require manual setup, refueling, and operation, whole-house generators automatically detect power loss and start running within seconds, restoring electricity without any manual intervention.

    Protection for Essential Appliances

    A power outage can damage or disable appliances such as refrigerators, medical equipment, sump pumps, and water heaters. A whole-house generator ensures that these critical systems remain powered, preventing food spoilage, basement flooding, and medical emergencies.

    Increased Home Value

    A professionally installed whole-house generator is a valuable investment that enhances your home’s marketability and resale value. Homebuyers in San Diego recognize the importance of backup power, making your property more attractive.

    Energy Efficiency and Cost Savings

    Power outages can lead to unexpected expenses such as hotel stays, spoiled groceries, and business disruptions for those who work from home. A whole-house generator eliminates these inconveniences and financial losses, making it a cost-effective solution in the long run.

    Reliable Fuel Source

    Generac whole-house generators run on natural gas or propane, eliminating the need for constant refueling like with gasoline-powered portable generators. This ensures continuous, long-term operation during prolonged outages.

Just had Evan G from Mauzy do an evaluation on the plumbing on my home. The evaluation could not have been more complete.
Every bit of the plumbing was checked. Yes everything was good to go but if there was an issue Evan with his knowledge would not have missed a thing. At least 2 hours to go through all the plumbing. I recommend every home owner to get the same service. It will save on the long run and if there are minor issues you will be made aware. Evan G was terrific.

5

Kory was great and very thorough , thank you

Mouzy is hands above any other plumbing/electrical A/C, firm I’ve used in the past, and since I am 80 years old, I’ve used a heck of a lot of them. They are fair, polite, and knowledgeable. I have no idea what More can think of to describe them.
You’ll be happy with them!

Joshua was professional and courteous. His detailed description of filtration systems, along with inspection and recommendations for correction of my failed in line water filter were a sell point for the filter I subsequently purchased from Mauzy plumbing. He provided above and beyond service, tightening fixtures and replacing piping and components at no extra charge. He demonstrated how water quality reflected filter performance, which turned out to be what he predicted it would. I was more than satisfied with Joshua’s informed and thorough

I should’ve called Mauzy first! Prior to the call to Mauzy I had 2 companies come out to help me with a plumbing issue I had. Let’s just say it got worse rather than better. Finally, Wilber, an exceptional young man to say the least, came to the rescue! Knowledgeable, efficient, and walked me through every step of the process. Pinpointed the problem and had my plumbing issue resolved. Thank you Mauzy for having exceptional employees that know what they are doing! Will continue my services with Mauzy.

He quickly identified the issue and took the time to explain my options clearly. He made sure everything was cleaned up and working perfectly before leaving which made the whole process smooth and stress-free. Definitely recommend this company and highly suggest you request Wilber!

5

Mauzy plumbing installed a tankless water heater for me in February and they did a superb job. The technician from Mauzy who installed my tankless water heater was Franky. I recently had a question about my system and Mauzy immediately sent Franky back to my home to evaluate the situation. He did a thorough analysis and determined that everything is good. I’m sure all of the Mauzy technicians are excellent, but if I ever have a complicated plumbing problem in the future, I would specifically ask for Franky; he is extremely knowledgeable and thorough and I can’t recommend him and Mauzy highly enough.

5

Mike Kesner was great! Professional, knew what to do to check the issue and was efficient in its resolution.

Excellent both times. Technicians were knowledgeable and polite. Respectfull of my house. Top notch service.

I recently had the pleasure of working with Joe Annello from Mauzy Cooling, Heating, Plumbing, and I cannot say enough about how great the experience was. From start to finish, Joe stood out for his exceptional professionalism and friendly demeanor, making what could have been a stressful situation feel effortless and reassuring. Joe was incredibly thorough in his work, taking the time to carefully assess and diagnose the issue. It was obvious that he takes pride in his work and genuinely cares about providing the best service possible. His attention to detail was truly impressive, and he made sure everything was checked over meticulously before giving his recommendations. What really set Joe apart was his ability to explain everything he found clearly and in a way that was easy to understand. He never rushed through the details or overwhelmed me with technical jargon; instead, he patiently walked me through his findings and the steps needed to resolve the issue. It made me feel confident and informed about the situation, which I really appreciated. Joe’s combination of friendliness, thoroughness, and clear communication truly makes him a standout technician. If you’re looking for someone who is not only skilled but also goes above and beyond to ensure an excellent customer experience, I highly recommend Joe Annello. He represents Mauzy Cooling, Heating, Plumbing in the best possible way and is someone you’d want working on your home!

5

A water heater breaking & unique older home piping/water pressure situation made what should have been a routine water heater replacement a bit more complex, and Ron, Ryan & Kacey were great in helping us get this quoted and serviced in the same day. I appreciate how communicative Ron was and how flexible Ryan was with our crazy schedules!

5

Chris Sotelo, Alejandro, Eddie and Westin were amazing today. They came to install a new A/C Heater unit and did a great work. They were knowledgeable, careful handling the equipment and did everything in a timely way. Thank you to this crew team!
