Best praise vs top criticism for Generac Guardian Series
“In Tampa, I used I & C Electrical Contracting Services LLC. 26/22.5kW Guardian Air-Cooled Generator with two 200A SE ATS installed was just under $20,000. Excellent workmanship. Great owner to work with. He came out and did the final quality check and initial start up. They also have a yearly maintenance plan. I also had a 500 gallon propane tank installed underground by Gaspros for a little over $5,000. Ninja gas supplies me with propane. Lowest cost around. Contact me privately if you have any questions.”
