Replacing my current equipment
March 09, 2023
Overall, Fronteir provided a great service from start to finish. Despite the large job, they finished the actual project within the projected "days expected". I do believe the project was a little larger than they anticipated, but they did well overall. There were a few small hiccups, with airflow (due to the size of my home), and plumbing (due to a request we required of them), but even then, they did attempt to remedy these situations in a hasty manner. A few times I do feel we were almost "gaslighted" so to speak regarding these above mentioned issues, but overall I would recommend this company to anyone requiring HVAC needs.

We were very impressed, from our first and ongoing contact with Jordan, with his knowledge and recommendation of Frontier's products. The men who installed the furnace and air conditioner were also very professional and courteous, informed us of each step they were taking during the whole process. We would definitely recommend Frontier and their products.

From the very first call I was treated like I was the owner. From the secretary to sales to the technicians everyone answered all my questions and gave me complete information too enable myself to understand and make good sound decisions as to the cost difference type of equipment I wanted and recommendations as to what was available for me to choose from. All this was done without pressure of sale but instead with concern for what I wanted and making sure that all my concerns were addressed and that there were no questions left unanswered. Now the surprise, all the work was in one day. This included removal of the old system inside and outside and installing the new high performance unit including smart thermostat hooked up and working and training on how everything works. Simply The Best !!!

This company is first class all the way. The knowledge and service was exceptional. I purchased a new infinity Carrier System and it was a big job. The team worked hard, communicated regularly and cleaned up EVERYTHING after the installation! They even vacuumed the room near the installation area!! The pricing is very competitive and I purchased a service contract for regular maintenance on my new system. Super Happy with this team of experts!!!!
