Our AC cut out in late June, and we were told by our oil company that solving things would be difficult. We found a volunteer energy consultant who helped us look at a range of options. We received four quotes, each offering different services and products, and ultimately chose Endless Energy. It was a bit tricky to move from sales to implementation, but when we spoke up, we were immediately given a team and supported throughout. Travis was our lead (he was excellent, communicative, and helpful), and the rest of the team (Jose, Hunter, and JT) kept things moving along, and installed a system that we think will keep us cool in summer, and warm in winter. It was a significant (and costly) step, but it was huge to eliminate oil and move forward. If you are working with Endless Energy, try to get Travis in your court. The folks in the office are also helpful in many ways, so please call and ensure they know what you are looking for.
