Best Freon Leak Detection in Kansas City MO

We had a sewer odor problem that occurred when the HVAC was in use--- this was during the heat wave and we were sweltering. Trevor came out, determined the problem, and repaired three different items quickly and effectively. The solution needed an HVAC pro, too, so his co-worker came soon after and proposed a cost-effective solution (re-routing air supply). Highest possible recommendation. Honest, competent, fast, and efficient (and really nice guys).
