CLIFF's Professionals Deliver Quality
Author Mark Edward Langley2025-03-11Trustindex verifies that the original source of the review is Google. We have sold our home and had Matthew from Cliff’s come out and take care of the few things the inspector pointed out. Matthew was on time and very polite. We love Cliff’s (for the last 5 years) and will use them at our new home after we get settled in. Doug Goins2025-03-03Trustindex verifies that the original source of the review is Google.

Yesterday, we had Hunter, Edward, and Robert install a home Generac generator. This team was so professional. They were super clean and respectful of the property. Hunter was the original contact who sold us the equipmet. We are impressed that he also worked on the installation. The employees really do care about getting the job done right. They answered all our questions and were genuinely concerned about customer service and our satisfaction. For these reasons, I highly recommend that you purchase your generator from Cliff's and I am adding a 6th star too this review too!
