Long-term customer satisfaction

James, Garrett and Chris did a fantastic job installing our new Carrier Infinity heat pump and furnace. Everything was done carefully and they cleaned up when done. James took a lot of time helping us choose the right system and answered all our questions. He also came out just prior to installation to go over the process and on the day of installation to make sure everything was completed.
