I had them install my furnace and was so pleased the next year I had them install central air. I had one problem over a weekend when my furnace wouldn't start. (switching from a/c to furnace) and a repairman came without complaint. There was a small issue with the a/c install that was discovered on the yearly check. The repairman was honest and fixed the issue and didn't charge me for the yearly check. They made it right! So happy to see a company accept responsibility for a problem they could easily cover up.
