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.

Every team member at Frontier were fantastic! They were patient and answered all questions and concerns leading up to the day of install. For the install, the crew arrived on time and finished on time as promised. The install crew were professional, courteous and left the job spotless. Absolute professionalism from begonia to end. Thank you!

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.

I was very pleased with my experience with Frontier Air Conditioning. From the first phone call after my old AC failed until my new AC was installed everyone were friendly and professional. I recommend them for your AC and heating needs.
