"Very accommodating and helpful with suggestions when it was noticed that the fan we purchased was defective..our installer came back in the afternoon to install the replacement fan. Check your purchases at Home Depot before you leave the store...our Hunter Fan was definitely returned by a previous customer and then put back on the shelf. The Company and installer handled the job very efficiently and professionally and we would highly recommend."

"I used Peak Power to install the electric for an above ground pool we had installed. Adam with Peak was incredibly helpful and responsive. My pool installers had many delays and ultimately finished the pool almost a month after the initial planned install. Adam/Peak were responsive to the ever shifting timeline and made it out within a few days of the completed pool install and almost a month after the plan. The scope of the project increased a little based after the final install and the Peak team was up front, honest and fair about the additional work and materials required. I would highly recommend Peak for all your electric needs."
