Tim, Rex and the whole team were incredible start to finish! We had two furnaces replaced (oil with propane) at our church, Cornerstone, in Holley, NY. The team is very knowledgeable, professional and thorough. They answered every question we had – and there were a lot! The installation was very neat and done faster than we anticipated. They demonstrated how to used the system afterwards. We are very pleased!

Less than a week after the installation at the church, our 24 year old hot water tank at our home started leaking. I called Frontier, walked upstairs and the tech was in our driveway! They were faster than the police!!! Rex gave us three suggestions/estimates and the next day a whole team had our new tank installed in about two hours. They were awesome! Very professional, knowledgeable, friendly and clean! Their response time is unbelievably amazing!

We are so grateful for Frontier and we HIGHLY them for both commercial and residential jobs! Thank you so much Frontier!!!!
