We will bring our expert team to your site and analyze your options and provide you with a detailed price quote. We do this at no cost to you.

The total price of an installed generator set depends on the size of generator which is a function of what circuits you want backed up during a power outage; the distance and ease of connection to your fuel source; the distance and ease of connection to your electric service; the amount of trenching required; whether you are looking for a natural gas or diesel generator; and need for noise attenuating enclosure or noise dampening screening or landscaping.


Whole House Coverage

This involves a generator large enough to back up the electric circuits in all of the breaker   panels in your house.

Select Circuits

This involves a generator sized to backup only those circuits you feel you need during a power outage. These are generally placed in one breaker panel with a 100 or 200 amp automatic transfer switch. Circuits generally selected by customers to be backed up are heat; sump, well, and septic pumps; refrigerators and freezers; stove top and microwave; hot water heater, medical equipment; select lights and outlets in kitchen, master bed and bath, home office, family room, mechanical room, security system, and safety lights in hallways, garage lights and doors. With automatic load management, additional circuits such as air conditioning and washer/dryers can be added.


Whole House Coverage for many average size houses with one breaker panel and 200 amp service is provided by the Cummins RS-20 kW generator with its automatic load management feature at prices depending on costs of hookup ranging from $14,000 to $17,000.

Whole House Coverage for larger houses or buildings with 400 to 1000 amp services and those with multiple electric heat pumps usually dictate generators that provide 25,000 to 60,000 watts. Whole house generators fully installed with all permits and inspections, warranties, sound attenuating enclosures, proper site location and concrete base generally range upwards from $25,000.
