Providing Expert Service Since 2007

Are You Prepared for the Next Power Outage?

Frequent Storm-Related Outages

Severe weather knocks out power for hours or days. A whole home generator keeps your family safe, comfortable, and connected when the grid goes down.

Medical Equipment & Home Office Dependence

If your household relies on medical devices, refrigerated medications, or a home office, even a brief outage can become a serious health or financial risk.

Food Spoilage & Property Damage

Extended outages lead to hundreds of dollars in spoiled food, failed sump pumps causing flooding, and frozen pipes in winter. All of that is preventable with a standby generator.

Aging or Unreliable Power Grid

Older infrastructure and increasing demand put strain on the electrical grid. A whole home generator provides independence from utility reliability issues.

Complete Home Generator Installation Services in Miami

Homeowners in Coral Gables, Kendall, and Brickell need dependable backup power when hurricanes, tropical storms, and grid strain during peak summer demand disrupt service. Intense humidity, hurricane exposure, and dense older housing keep Miami-Dade electricians busy year-round. Proper whole home generator installation in Miami matters because poor work can lead to carbon monoxide exposure, dangerous electrical backfeed, and code violations. We install backup power systems designed to keep your home running when the grid goes down.

Whole Home Standby Generator Installation

Whole home standby generators detect an outage and restore power within seconds without manual intervention. We install standby generators from Generac, Kohler, and Briggs & Stratton, with natural gas and propane fuel options. Professional installation ensures code compliance and reliable performance.

Standby Generator Services:

Automatic Transfer Switch Installation

A transfer switch disconnects your home from utility power and connects generator power during an outage, preventing dangerous backfeed that can endanger utility workers and damage equipment. We install automatic and manual transfer switches for whole-home and critical-load applications, with seamless integration into existing panels and panel upgrades when needed.

Transfer Switch Services:

Generator Sizing & Load Calculation

An undersized generator can overload during an outage; an oversized unit wastes fuel and money. Our load calculation evaluates essential circuits, starting and running wattage, HVAC systems, major appliances, well pumps, and other high-demand equipment, plus future needs such as EV chargers, pools, workshops, or home additions.

Sizing & Consultation Services:

Generator Maintenance & Repair

Standby generators spend much of their lives waiting for emergencies, making regular maintenance critical to reliable performance. Our maintenance services include oil and filter changes, battery testing, fuel system inspections, transfer switch testing, and load bank testing to verify proper operation. Neglected generators frequently fail when they’re needed most, but routine service helps maximize reliability and extend equipment life.

Home Generator Installation FAQs for Miami Homeowners

How much does a whole home generator installation cost?

Costs vary depending on generator size, fuel type, site conditions, permitting requirements, and installation complexity. Entry-level essential-load systems typically cost less than full-home standby systems. Factors such as transfer switch installation, gas line work, electrical upgrades, and site preparation all influence pricing.

What size generator do I need for my home?

Most homes require anywhere from 10 to 16 kW for essential circuits, 16 to 22 kW for broader coverage, and 22 to 48+ kW for full-home backup. The right size depends on your home’s square footage, HVAC systems, appliances, and lifestyle needs, and a professional load calculation is the only accurate way to determine proper sizing.

How long does generator installation take?

Most standard installations can be completed within one to two days. Projects requiring gas line extensions, panel upgrades, or extensive site work may take two to four days. Including consultation, permitting, inspections, and equipment ordering, the overall process typically takes two to six weeks.

Do I need a permit to install a whole home generator?

Yes, most jurisdictions require permits for standby generator installations. Our professional installers handle the permitting process and inspections to ensure full compliance with local codes and manufacturer requirements.

What fuel type is best for a home generator, natural gas or propane?

Natural gas provides a continuous fuel supply through utility connections and lower operating costs, while propane remains flexible and available even if gas infrastructure is disrupted. Dual-fuel options may also be available.

Do you provide generator maintenance plans?

Yes, scheduled maintenance helps keep your system operating efficiently and ready when outages occur. Our maintenance services include oil and filter changes, battery testing, fuel system inspections, and transfer switch testing.

How We Carry Out Generator Installation for Miami, FL, Homes

Thorough prep work is essential for proper generator placement and installation. We start by making sure that the desired installation site:

Is completely level
Has a base pad made from pea gravel or concrete

We then precisely place the generator on top of this base. Next, we install a transfer switch adjacent to your home’s breaker panel or fuse box. This switch tells your generator when it needs to start and stop sending power to your electrical system. There is also a part of the installation process that doesn’t fall within our skill set as electrical professionals. Namely, you need the appropriate professionals to hook your generator up to a natural gas or propane supply line. When these professionals complete their work, we step back in and test your generator to make sure it’s producing power as intended.
