Understanding the different options available ensures you select the right fit for your household's needs. Whole-home generators provide seamless, automatic power restoration to your entire house, ensuring maximum comfort during outages. Standby generators are perfect for those who want peace of mind with minimal disruption, automatically turning on when the power goes out. Backup generators serve as an immediate power source for essential appliances, offering a practical solution in emergencies.
Generator Installation & Replacement
Whether you want to install a generator for your new home or need to replace your old, faulty generator, you can rely on the pros from David Gray. We handle generator installation and replacement work for residential clients. We’re an authorized dealer for Generac, a trusted brand known for quality.
For basic generator installations, we install a power inlet for your portable generator to plug into during a power outage. We then install a manual transfer switch in your electrical panel so you can safely and easily switch from the power grid to your generator. During a power outage, you would plug in your portable generator, start it up, and turn the transfer switch to 'generator mode.' We can install transfer switches that manage your entire home so that you don’t have to connect your generator when you want to use it manually.
Our team can also handle turnkey installations. We will purchase and deliver your generator and install your critical power loads. Once everything is complete, a certified generator specialist will start your generator and set your generator run cycle and power settings. These backup generators come on automatically when your power goes out and turn themselves off when your power is restored. They also automatically turn on once a week to exercise the motor and only need maintenance once a year.
Selecting the right generator installation method depends on your power needs and lifestyle. Basic installations are ideal for those who want to manually control their generator use during outages. On the other hand, turnkey installations offer a more hands-off approach, providing automatic responsiveness and minimal interaction while ensuring your home remains powered safely and efficiently. Experienced with multiple setups, our team ensures that your generator system is tailored to your unique requirements for reliability and convenience across Jacksonville.

Benefits of Installing a Generator in Your Florida Home
It’s worth investing in a generator for your property, especially in places with hurricanes and bad storms, like Florida. Installing a generator will improve your:
- Comfort: You can keep the lights and HVAC system on during an outage.
- Safety: You’ll be able to navigate your home without flashlights and charge your phones and medical equipment.
- Convenience: A whole-home generator will switch on automatically when there’s an outage.
- Peace of mind: You’ll feel better knowing that your family will have electricity, entertainment, and other necessities during an outage.
Beyond individual benefits, generators also contribute to community resilience. In the aftermath of severe weather events, a neighborhood equipped with backup generators can foster a sense of community stability, ensuring communication lines remain open, and essential appliances function smoothly despite external challenges. This collective preparedness reduces strain on emergency services and empowers residents to assist each other, promoting community safety and cooperation.
How to choose the right generator size for your home
Selecting the correct generator size is critical for meeting your household’s power needs without overspending. Consider the following:
- Calculate essential loads: List appliances and systems you want powered (HVAC, refrigerator, lights, medical equipment).
- Add starting wattage: Some appliances require more power at startup, such as air conditioners and pumps.
- Factor in future needs: Will you add new appliances or expand your home?
- Consider fuel type and availability: Natural gas, propane, or diesel—each has pros and cons.
- Consult a professional: An expert evaluation from David Gray ensures accurate sizing and compliance with local codes.
Preparing your home for generator installation
Preparing your property for generator installation can streamline the process and avoid delays:
- Clear the installation area: Ensure a flat, accessible space outside your home, away from windows and vents.
- Review local regulations: Some neighborhoods or HOAs have specific requirements for generator placement and noise.
- Check existing electrical systems: Upgrading your panel or installing transfer switches may be necessary.
- Plan fuel supply logistics: Discuss fuel delivery or tank installation with your installer.
- Schedule installation before storm season: Early preparation prevents last-minute rushes and supply shortages.
