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.

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.

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.
