We have always had excellent service from Frontier. They always arrive within time window. Their technicians are very knowledgeable, efficient and clean up after themselves. Robert was great about explaining everything he had done and suggested additional service that should be performed.

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.

Justin Siguenza of Frontier AC just left my house after providing bi-annual services. He is a very professional tech and I was also impressed with his friendliness. I hope to see him again in six months.


Called for service and the tech was at my door in about an hour! Victor was very professional and explained his processes, repairs and suggestions thoroughly. He got our unit up and running in no time! I will definitely stick with Frontier for any future services.

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.
