Wonderful Job and Service – From the start, Frontier has been amazing to deal with. Our sales rep Rex was very thorough and explained everything every step of the way. They were very accommodating and understanding. Once we were able to get the AC unit installed, the technicians were here first thing in the morning and worked hard to get everything up and running. They were very professional and did an amazing job. They also explained everything once it was all set up on use, maintenance and what to expect going forward. We are very pleased with Frontier and will be using them going forward for any maintenance or upgrades to our home. Thank you!!!  James R.
