  • 2 service visits included in year one
  • Fluid checks, battery test, load test, and inspection
  • No hidden fees — included with every installation we do

What Changes the Installed Price?

Generator size, transfer-switch capacity, gas or propane availability, concrete-pad location, trenching distance, electrical-panel condition and local permit requirements all affect the final quote. Imperium provides an on-site assessment before recommending a system. We also handle electrical panel upgrades when the existing panel needs to be brought up to capacity before generator installation.

"I had a wonderful experience with the technician who arrived to my residence within one hour of a requested visit to help me establish the WiFi connection to my generator. He explained the generator functions in a manner that was easy to understand. He is knowledgeable, polite and technically competent. His name is Evan and because of him, I highly recommend Imperium for your generator needs."
