Generator Type

There are several types of generators worth considering when determining whether a whole-house generator is right for you.

Power Type 

On average, you’ll spend about $90 to $220 daily to run a 15-to-20-kW whole-house generator in Orlando, FL. But not all fuels are alike, and depending on the brand and fuel you choose, you might spend far more than you expected in fuel costs.

Here is how much each of the best fuel types cost per year or unit:

Whole-house Generator Installation Pro Costs

The cost to hire a generator installation professional in Orlando, FL is about 15% lower than the national average, contributing to more affordable overall prices. According to the Bureau of Labor Statistics, the average construction worker labor rate in Orlando, FL, is $19.50 per hour. The high number of skilled contractors competing for work in the city means you can easily secure fair quotes.

This is comforting, as installing a whole-house generator yourself isn’t a DIY-friendly undertaking. Mistakes made during electrical rewiring or gas connection upgrades can create fire hazards or carbon monoxide risks.

Instead, hire a reputable local general contractor who is familiar with Florida building codes and any hurricane-related incentives and requirements. They can also recommend the best generator size based on your home’s energy demands.

Labor

Labor costs increase if your generator installation requires additional upgrades or site preparation that add time and complexity to the project. While Orlando, FL’s flat terrain and sandy soil can make some installations straightforward, installations on neighborhoods with steep slopes, such as Clermont or Altamonte Springs, will be more protracted.

Permits

Installing a permanent standby whole-house generator in Orlando, FL, usually requires electrical and building permits. Building permit costs range from $65 to $260, depending on the scope of the project. Permits aren’t usually required for portable generators.

When you hire a licensed contractor, they’ll handle the permitting process and be familiar with the Florida Building Code and National Electrical Code requirements, including any hurricane-specific construction practices. However, you can also contact the City of Orlando, FL’s Permitting Services Division directly for information on codes, costs, and the application process.

Licensing

A licensed contractor must carry out whole-house generator installation in Florida. If you hire a professional who doesn’t have a valid Florida Electrical Contractor License and a Certified Residential Contractor License or the proper liability insurance, it can result in failed inspections, fines, and unsafe gas or electrical work. You can verify your contractor’s licenses through the Licensing Portal of the Florida Department of Business & Professional Regulation.

Hiring a qualified professional ensures your generator is installed safely and in compliance with local regulations.

Does Installing a Whole-house Generator Increase Home Value?

Installing a whole-house generator is worth it in many homes in Orlando, FL. While there are pros and cons to whole-house generators, the right system can improve your property value and market appeal. Reliable backup power is especially attractive in Florida, where storms and hurricanes can cause regular power outages. 

The average return on investment (ROI) for a standby generator in Orlando, FL, ranges from 75% to 150%, depending on the generator capacity, fuel type, and installation quality.
