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. For all other licensed electrical services, see our electrical services page.

"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."
