Key Benefits of Whole House Generators

Some of the main benefits of a generator for your home include:

Reliable Power for Entire House

Whole house generators provide backup power to your entire home, allowing you to continue using your furnace, lights, refrigerator, and other essentials during an outage. This ensures your daily life is not impacted.

Automatic Activation

The system will detect a power loss and automatically activate within seconds, providing a seamless transition to generator power. This prevents any disruption.

Supports Extended Outages

These systems have large fuel tanks and can operate for long periods, such as during multi-day blackouts from storms. This allows normal household function no matter how long the main power is out.

Surge Protection

The generator will protect sensitive electronics and appliances throughout the home from power surges/damage that can occur when power is restored.

Increased Home Value

Having a whole house generator system installed increases your home’s resale value and appeals to buyers by ensuring reliable backup power.

Potential Insurance Discounts

Types of Whole House Generators

There are two main types of whole-house generators to choose from:

Standby Generators – These are permanently installed outside your home and connected to your electrical system. They automatically detect outages and start within seconds to restore power.

Portable Generators – Portable generator units can also be adapted to integrate with a home’s electrical system. However, they require manual start-up and won’t detect an outage automatically.

Choosing between a standby or portable system depends on factors like budget, features, and convenience.

Proper Generator Sizing

Choosing a generator with adequate power for your whole house’s needs is crucial. Consider factors like:

  • Square footage of your home
  • Number of circuits and major appliances
  • Essential items you want to power like AC, heat, kitchen, etc.

A professional can help determine ideal generator sizing to meet your electrical demands and run seamlessly when needed.

Generator Fuel Source Options

Key generator fuel options include:

Natural Gas – Connects directly to your home’s natural gas supply for automatic, uninterrupted fuel as long as service is active.

Propane – Propane fuel tanks must be large enough for extended run times and occasionally refilled.

Diesel – Diesel generators tend to be the most powerful but require maintenance and refueling as well.

Each has pros and cons to weigh for your situation. A reputable generator provider can help choose the optimal power source.
