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

  • 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.

Here’s What Others Are Saying About Us

Carlos and Chandler were SUPERB installers! We got a very effective AC and Heating system for far less than I expected. We felt the difference right away as soon as we turned on the air conditioning unit. As important, Mauzy configured the system to optimize efficiency. I highly recommend you get a quote from this company if you’re in need of replacing your old equipment.

Update 2: my trust is restored. Had a little leakage in my box that connects to the fan and Luis went up in the attic and got it all sealed. Luis was very polite, professional, and genuinely happy. His positive attitude was very contagious and made my experience top notch. Also, I am happy to report that Mauzy stood behind their workmanship and covered all repairs under warranty. So so refreshing to have any company stand behind their workmanship. I have been with Mauzy since 2020 and will continue to be their customer. I would recommend Christian, Kylie, or Luis as your tech as well as recommend anyone out there to use Mauzy.Update: My trust is returning to Mauzy. Christian and Kylin came out to repair the repair and get my A/C up and running before the heat returns. Christian and Kyle were very professional, explain everything before proceeding, and let me know that the work would be covered under warrantyI have lost trust in Mauzy, Mauzy doesn’t stand behind their own work and what good is a warranty if you don’t stand behind it (This is a long one so sit tight). Where it all began: March 2020 I purchased a $23K A/C heating system from Mauzy. I was super happy with the install and I still love my system. I faithfully have used Mauzy service for my HVAC system every year since the install. I went with Mauzy bc they claim to stand behind their workmanship for the lifetime of the system (See Mauzy’s Attachment stating it also on their web page). Where the exchange box hooks up to the fan/heater a breach occurred between the box and the fan (service guy found it during my scheduled service in May 2024). It cost me approx $450.00 to have that breach fixed. Not sure why I had to pay if Mauzy offers a lifetime warranty on their workmanship, right? Matt Mauzy, feel free to explain this to me(see Mauzy’s warranty claim attached). I am open minded and perhaps my LA unified school education failed me. I got into it with one of Mauzy’s techs during the 2023 service for an issue with their workmanship. So to keep the peace, I didn’t argue with the charge in May and paid the $450 to have Mauzy repair their workmanship. Sunday 14 July, the repair Mauzy charged me for in May, didn’t hold up. I can’t use my heating or A/C bc it just dumps out in my attic. So Sunday I called the service line and the lady assured me there was no issue and scheduled a service call for the following Monday (15 July) no specified time. So this morning I made sure I was ready by 7am in case a technician showed up early. Around 9:15 I decided to call to see if I could get a better timeline from Mauzy only to find out that I don’t have an appointment yet. Come on Mauzy! why would your service desk make me believe I have an appointment when I don’t? Right? I would not have been so disgruntled if the service desk had told me someone would call me Monday morning to schedule. Matt Mauzy, you need to fix this. The soonest Mauzy can come out to fix their shoddy workmanship is sometime Thursday (maybe). I pray that this weeks heat wave is not too severe (this leads up to a whole other reason I need to get my A/C fixed). I will be thinking of you Matt Mauzy while you sit in your A/C house. Matt, Maybe you could come out from behind your desk and help your service department. I happen to be a tradesman and I have never left a customer in need hanging, especially if it was my fault. Just saying!Alex from Mauzy came out to conduct our annual service for our HVAC system. Good thing bc in of the seams in the unit had a hole and I was heating and cooling my attic. Super glad I have the inspection conducted every year. Alex was able to get the breach fixed and now the universe is rotating in harmony once again. BTW, I have been using Mauzy for the last 5 years (Mauzy also installed my HVAC) and I couldn’t be more satisfied. Mauzy truly does a good job and stands behind their work. Thank you Mauzy!

I am really happy with the customer service at Mauzy. Not only did they get me in promptly to replace my HVAC, they also beat the quotes of the other companies I contacted. Matt, Mario and Kenneth were really great explaining the process and getting the job done. They were respectful of my home and made sure my floors didn’t get dirty and cleaned up all the debris from the install. They made sure the unit was fully functional, testing temperatures and explain how to operate the system. I highly recommend Mauzy.

Kenneth and Mario are brothers! They were very respectful, happy and worked harder than I have ever seen anyone work. I had a pool delivered and on their break they offered to carry it to the backyard for me, and they helped get the last piece of the frame locked in as I was not strong enough to do it. They were so quiet I forgot they were in my attic. They were truly amazing! They cleaned up everything, it was like they were never here. I highly recommend Kenneth and Mario from Mauzy heating air and solar. Great job and thank you!!!

Michael at Mauzy worked very hard for two days to diagnose why our AC isn’t working. He had help from Jared the second day. A couple of burnt parts were replaced but it was determined an electrician was needed before they could complete their job. I did not meet Jared but Michael was professional, diligent, thorough and tidy and a pleasure to work with. I appreciated the detailed report afterwards. I am waiting for an updated invoice that details the discount I am due for signing up for their service plan. An electrician has been out and done his work. I’m waiting to hear about a follow up appointment to finish the AC issue. If I can get back to this review, I will update it when the service is complete. I’m new to Mauzy and so far am impressed.
