Generator Services in Orlando, FL

Thomas Edison Electric installs, sizes, and maintains whole-home standby generators and portable generator systems for homeowners and businesses across the Orlando metro — including Lake Mary, Sanford, Winter Park, Maitland, Apopka, Ocoee, Oviedo, Altamonte Springs, Winter Springs, and Casselberry. Whether you need a permanent natural-gas unit with an automatic transfer switch or a properly wired portable setup for storm season, our licensed electricians handle every step — from load calculation through final inspection — so you never lose power when Florida’s weather turns hostile.

Why Generator Services Matter in Central Florida

Central Florida ranks among the most lightning-strike-prone regions in the United States, and the Atlantic hurricane season runs a full six months — June through November. Orlando sits far enough inland to escape direct storm surge, but tropical storms and hurricanes regularly knock out grid power for days across Orange, Osceola, and Seminole counties. Summer afternoon thunderstorms alone cause thousands of outages each year.

Beyond storms, Florida’s extreme heat turns a power outage into a health emergency within hours. Air conditioning, refrigerated medications, sump pumps, and well pumps all depend on a reliable power source. A properly sized generator keeps your home safe, your food preserved, and your family comfortable whether the outage lasts four hours or four days. For businesses, even a brief interruption can mean lost revenue, spoiled inventory, and frustrated customers.

Central Florida Generator Context

Most Orlando-area homes are served by Duke Energy Florida or OUC (Orlando Utilities Commission), both of which experience concentrated outage clusters during named storms and the daily pop-up thunderstorms that sweep through from late spring through early fall. Neighborhoods differ in how exposed they are: older in-fill areas of Winter Park and Maitland with mature tree canopies see more outage events from wind-damaged lines than newer subdivisions in Ocoee or the Lake Mary corridor where underground distribution is more common.

HOA communities throughout Seminole County — particularly in Altamonte Springs, Winter Springs, and Casselberry — sometimes have placement rules for generator pads and propane tanks. We are familiar with those local requirements and coordinate approvals before work begins. Homes in Sanford and Apopka on private well systems have an added urgency: no power means no water, making generator sizing for the well pump a primary concern rather than an afterthought.

Generator Services We Offer

This page is the hub for all generator work we perform. Each service below links to deeper detail where available.

Whole-home standby generators — Permanently installed units that start automatically within seconds of an outage, with full permitting and panel integration. For complete specs on equipment selection, pad placement, gas line coordination, ATS configuration, and the step-by-step installation process, see our dedicated standby generator installation page.
Portable generator wiring and interlock kits — If you already own a portable generator, we install a code-compliant transfer switch or interlock kit so you can safely connect it to your home’s circuits without backfeeding the utility line — a legal and life-safety requirement under NEC Article 702.
Load sizing and circuit selection — We calculate your essential loads (HVAC, refrigerator, medical equipment, lighting, well pump) and recommend the right generator capacity for your specific home and budget, avoiding both over- and under-sizing.
Generator maintenance and annual service — Generators must run regularly and be serviced to start reliably when needed. We offer maintenance plans covering oil changes, filter replacements, load-bank testing, and battery checks so your unit is ready before the next storm.
Permits and inspections — All generator work in Orange, Osceola, and Seminole counties requires permits. We pull permits, schedule inspections, and ensure the installation meets Florida Building Code and NEC standards so your homeowner’s insurance remains valid.

Signs You Need Generator Service

Your area lost power for more than a few hours during last year’s storm season and you had no backup.
You or a family member depend on powered medical equipment such as a CPAP, nebulizer, or home oxygen concentrator.
You have a well pump, sump pump, or security system that fails without power — especially relevant for Sanford and Apopka homes on private wells.
Your existing portable generator is connected with an extension cord run through a window — a code violation and a carbon-monoxide risk.
Your standby generator has not been professionally serviced in over a year or fails its weekly self-test cycle.
You are adding square footage or major appliances and suspect your generator is no longer sized correctly for your loads.

Financing and Related Services

Generator projects are a significant investment that pays off the first time the lights go out. We offer flexible financing options through GoodLeap, Turns, and Synchrony — visit our financing page to learn how to spread the cost over time. Generators work best as part of a complete electrical system — explore our related services including electrical panel upgrades to ensure your panel can handle the transfer switch, and whole-home surge protection to guard your equipment when power is restored.

Frequently Asked Questions

How large a generator do I need for my Orlando home?

Size depends on which circuits you want to power and the starting current of your largest motor loads — typically your air conditioner compressor. A modest 10–14 kW unit handles essential circuits in most 1,500–2,000 sq ft Florida homes, while larger homes or whole-home coverage may require 20 kW or more. We perform a load calculation on every project so the recommendation is specific to your home. For a detailed breakdown of the sizing process, see our standby generator installation page.

Is a permit required for generator installation in Orlando?

Yes. Orange County, Seminole County, and the City of Orlando require electrical and, depending on the fuel type, mechanical permits for standby generator installations. Skipping permits can void your homeowner’s insurance coverage for storm-related claims and create liability if the installation is ever involved in a fire or injury. We pull all required permits as a standard part of every installation.

What is the difference between a transfer switch and an interlock kit?

Both devices prevent a generator from backfeeding power onto the utility line — a requirement under NEC Article 702 that protects utility workers and your neighbors. An interlock kit typically costs less but requires you to manually switch circuits. An automatic transfer switch detects the outage and switches within seconds without any action on your part. We can install either, depending on your budget and how hands-off you want your backup power to be.

Do HOA rules affect where I can place a generator or propane tank?

They can. Many planned communities in Altamonte Springs, Winter Springs, Casselberry, and parts of Lake Mary have setback or screening requirements for generator pads and propane tanks. We review HOA guidelines as part of our site assessment and can advise on equipment placement that satisfies both Florida Building Code setbacks and community rules before any work is submitted for permits.

How often should a standby generator be serviced?

Most manufacturers recommend an oil and filter change every 100–200 hours of operation, or at minimum once a year, whichever comes first. Before hurricane season each June is the ideal time for a professional inspection that includes a load-bank test, battery test, fuel system check, and control board review. A generator that sits idle most of the year can develop fuel issues, stale oil, and corroded connections — problems that only show up when you need the unit most.
