Generator Repair
Is your generator leaking fuel? Are you having a hard time turning your generator on? Do not search the internet for DIY repairs and potentially damage your equipment or hurt yourself. Instead, reach out to us for generator repairs. We will figure out what is causing your generator issues and fix it as quickly as possible so that you have reliable power when needed.
Common signs your generator needs professional repair include:
- Difficulty starting: The generator cranks but will not start, starts and then shuts off, or needs multiple attempts to run.
- Visible fuel or oil leaks: Puddles, wet spots, or strong fuel odors near the unit that indicate line, seal, or tank problems.
- Unusual noises or vibrations: New rattling, knocking, or grinding sounds while the generator is running.
- Inconsistent power output: Lights dimming or flickering, or sensitive electronics not functioning properly when on generator power.
- Error codes or warning lights: Indicator lights or display messages that point to underlying component or sensor issues.
Effective generator repairs address both immediate issues and underlying causes to prevent future problems. Our team performs a thorough diagnostic evaluation to identify hidden faults that could affect performance.
By resolving these issues, your generator operates efficiently and reliably, minimizing the risk of unexpected downtime. This careful approach is especially important in areas prone to storms, where dependable backup power is essential for safety and comfort.

Benefits of Installing a Generator in Your Florida Home
It is 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 will 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 is an outage.
- Peace of mind: You will feel better knowing that your family will have electricity, entertainment, and other necessities during an outage.
Beyond personal benefits, generators help strengthen community resilience. After severe weather, neighborhoods with backup power can maintain communication, keep essential appliances running, and support overall stability. This preparedness reduces pressure on emergency services and enables residents to assist one another, promoting 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 supports 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 helps prevent last-minute rushes and supply shortages.

Commonly Asked Questions
How long can a standby generator run continuously?
Most residential standby generators can operate for many hours or even several days, depending on the fuel source and maintenance condition. Natural gas systems can run as long as the utility supply remains available, while propane units operate based on tank size. Built-in safety controls also monitor temperature and oil pressure to protect the engine during extended operation.
Do generators need permits before installation?
Yes. Permanent generator installation typically requires electrical permits and inspections to verify safe wiring, grounding, and transfer switch configuration. Professional installers handle permitting and coordinate inspections so the system meets local building and electrical codes.
Will a generator protect appliances from power surges?
A properly installed standby generator paired with a transfer switch helps stabilize voltage during outages and power restoration. While it provides cleaner power than many portable units, whole-home surge protection is still recommended to protect sensitive electronics like computers, smart appliances, and entertainment systems.
What maintenance does a standby generator require each year?
Annual service usually includes an oil and filter change, battery inspection, air filter replacement if needed, fuel system checks, and a full operational test. Routine maintenance keeps the generator ready for emergencies and helps maintain warranty coverage.
Can I run my air conditioner with a backup generator?
Yes, as long as the generator is properly sized. Air conditioning systems require higher starting wattage than most appliances, so the generator must be selected based on the home’s electrical load calculation. A professional assessment ensures the system can support cooling equipment safely.
What happens if the generator detects a problem?
Modern generators have onboard diagnostics that display alerts or fault codes. Many systems also offer remote monitoring, allowing homeowners to receive notifications if service is needed. Prompt attention to alerts helps prevent breakdowns during an outage.
Is a portable generator connected the same way as a standby generator?
No. Portable generators require a manual connection using a transfer switch or power inlet, while standby generators are permanently installed and operate automatically. A proper connection method is essential to prevent backfeeding and electrical hazards.
