Fred Pappalardo

Garret was incredibly helpful with my issue—knowledgeable, patient, and, in his own words, ready to “nerd out for a minute.” That line made me laugh, but I’m so glad I let him dive in. He broke everything down in the simplest, clearest way, and I walked away actually understanding what was going on.

Endless Energy installed our heat pump a few years ago, and they’ve been nothing short of exceptional ever since. Their responsiveness, their professionalism, and their genuine care have stood out every single time. In all these years, we’ve only had one small issue—and even that turned out to have nothing to do with their system.

Thank you, Endless Energy, for your continued excellence. And truly—give Garret a raise. He’s one of the best, friendliest, and most capable people I’ve ever had the pleasure of working with. He made everything easy to understand, and that kind of service is rare.
