➜ Generator Installation & Maintenance Services

Hurricane Milton left roughly 3.4 million Florida utility customers without power in October 2024, and many homes across Central Florida waited days for crews to reach their street. At ST Electric Services, our generator installation and maintenance work in Kissimmee, FL, puts Generac and Kohler standby generators on proper pads with automatic transfer switches, placed at least 5 feet from windows, doors, and vents as manufacturers require. As a Generac Certified Installer, we set up new systems for homes and businesses, then keep them ready with scheduled maintenance, load testing, and repairs on every generator brand, so the next outage is an inconvenience instead of an emergency.

AN OUTAGE SHOULD NOT DECIDE HOW YOUR WEEK GOES.

When the power drops in August, a house heats up within hours, refrigerated food starts spoiling, and medical equipment, sump pumps, and home offices go dark. A standby generator senses the outage and restores power automatically, usually within seconds, whether you are home or away. For businesses, it keeps registers, refrigeration, and security systems running while competitors lock their doors.


The protection only works if the generator is sized correctly, installed safely, and maintained between storms. We handle all three, so the unit starts when you actually need it.

➜ GENERATOR INSTALLATION & MAINTENANCE

STANDBY POWER BELONGS IN EVERY KISSIMMEE STORM PLAN.

Hurricane season runs from June 1 to November 30, and summer thunderstorms knock out neighborhoods between named storms too. An automatic standby generator removes the scramble of fueling and cabling a portable unit in the rain. We size each system to cover what matters most to you, from a few essential circuits to the whole house, including the air conditioning that makes a Florida outage bearable.

PLACEMENT RULES EXIST FOR A REASON.

Generator exhaust contains carbon monoxide, which is why manufacturers call for at least 5 feet between the unit and any window, door, or vent, along with open clearance above and around it. We plan every placement around those rules, your setbacks and property lines, and local permit requirements, then set the generator on a level pad positioned above standing water during heavy rain.

HURRICANE SEASON IS PART OF OUR JOB DESCRIPTION.

With 15+ years of electrical work behind us, we have seen what happens when a generator sits untouched until the storm arrives: dead batteries, stale fuel, clogged filters, and transfer switches that never engage. That experience is why we treat maintenance as seriously as installation. If your generator has not been started or serviced since last season, would you rather find out now or during the next outage?

WHY CHOOSE US FOR GENERATOR INSTALLATION.

POWER WITHOUT LIFTING A FINGER

➜ Common Questions

FREQUENTLY ASKED QUESTIONS.

Choosing and caring for a standby generator raises questions about size, placement, fuel, and upkeep. These are the questions homeowners and business owners ask us most before storm season.

  • What size generator do I need to power my whole house?

    Most whole-house systems for Central Florida homes fall between 20 and 26 kilowatts, depending on square footage and the size of your air conditioning. A load calculation that counts the starting current for motors gives the most accurate size.

  • How far does a standby generator need to be from the house?

    Many air-cooled units can sit 18 inches from a noncombustible wall, but they need at least 5 feet from windows, doors, and vents, along with clear space in front, on both sides, and overhead for safe service access.

  • What is a transfer switch and why is it required?

    A transfer switch safely shifts your home between utility and generator power. It prevents backfeed onto utility lines, which can injure line workers and damage equipment, and it keeps both power sources from connecting at the same time.

  • How often should a standby generator be serviced?

    Plan on professional maintenance at least once a year, ideally before hurricane season, with oil, filters, and battery checked each visit. Generators that run for long stretches during outages need an additional service visit afterward to stay dependable.

  • How long can a standby generator run during an outage?

    It depends on fuel. Natural gas units continue as long as gas service does, while propane models depend on the size of the tank. Manufacturers recommend periodic shutdowns for oil checks during outages lasting several days, especially in summer heat.

  • Is natural gas or propane better for a standby generator?

    Natural gas offers unlimited run time where a gas line is available. Propane works anywhere a tank can be placed and stores well for years. ST Electric Services helps Kissimmee, FL, homeowners compare both options before choosing a generator.

  • Can a standby generator run central air conditioning?

    Yes, as long as the generator is sized to handle the air conditioner's starting current. Soft-start kits on the compressor and load-management modules let a smaller generator handle cooling alongside other essential appliances without overloading the generator or the system.

  • What should I look for in a generator installer?

    Manufacturer certification, careful load sizing, and a maintenance plan after installation matter most when you compare installers. ST Electric Services is a Generac Certified Installer serving Kissimmee, FL, and services all generator brands, so support continues long after setup day.

➜ HOW WE WORK 

FROM SITE VISIT TO STORM READY, HERE IS HOW.

STEP 01

Walk the Property

We visit your home or business, review your panel and fuel options, and look at possible generator locations. We note clearances, drainage, and access so the unit can be placed safely and serviced easily later.

STEP 02

Size the System

We calculate the load you want covered, from essential circuits to the full property, including the starting current of air conditioners and pumps. That calculation sets the generator size and transfer switch configuration.

STEP 03

Prepare the Site

We confirm the location meets local permit requirements and prepare a level, well-drained pad in the approved spot. Placement follows manufacturer clearance rules for windows, doors, vents, and service access around the unit.

STEP 04

Install the Generator and Switch

The generator is set, the transfer switch is wired to your panel, and every electrical connection is completed to the manufacturer's specification. Every termination is checked and torqued before the system receives power for the first time.

STEP 05

Test Under Load

We simulate an outage, confirm the transfer switch engages, and run the generator under real load. Output voltage, frequency, and controller settings are verified, and the weekly exercise schedule is programmed before we leave.

STEP 06

Keep It Ready

We walk you through the controller, alarms, and what to expect during an outage, then set up a maintenance schedule. Regular visits keep the system ready and dependable for every storm season that follows.
