Had Miller's install a ductless mini split system about a year & a half ago. First hot day of spring fired up the AC and it blew only warm air. They were out in a couple days to diagnose. Took several tries with no luck to determine the issue and they went out of their way to replace the entire unit with a new one. Miller's team is super friendly, hard working and we would recommend their team to anyone needing HVAC services. Thanks Miller's!
