Very, very happy with Frontier services, our a/c unit went oit all of a sudden and we were needing to replace the entire unit, and not only did they give us a great price and customer service but they wen out of their way to send out technicians on a Saturday to provide immediate service. Technicians were great and very informative on the unit and any questions I asked. So thank you Frontier for your services.

Rigo did a great job for me. One of my own repairs blew a fuse within my air conditioner. Rigo figured out the problem, replaced the fuse, and explained everything to me so that I don’t make the same mistake again. I’m very impressed with his knowledge and friendly nature.
