Excellent service. Very friendly and informative.
Aaron my service tech was very professional and knowledgeable. Appreciate the good service.
Great service, very timely and professional. Explained everything is easy detail.
My grandfather and I were helped by a man named Jesse Brubaker, who was sent out to check out our ac system in a rental house that my grandfather owns and I run. He was extremely polite and helpful in explaining everything going on and broke down all the options we had available. I had to call my grandfather before making any final decisions and my grandfather called him back to ask a few questions since I'm not as well versed in those systems. Jesse went beyond the typical expectancy of doing exactly what is required to do and no more, and instead took time to check things thoroughly which saved us money and time on fixing things that may not have ever been an issue! Thank you Jesse for being so helpful and earnest in our interaction! I'd hope he gets some kind of recognition from the company for being an outstanding employee and making a customer very happy with the service and the personal experience.

How do I know if I need an electrical panel upgrade?

Frequent breaker trips, flickering lights, or an older panel that can’t handle modern appliances are clear indicators that a panel upgrade may be necessary. Undersized panels in many Cornwall homes built before 1980 often struggle to meet today’s electrical demands.

What are the benefits of installing a standby generator?
