I just didn’t like the fact that the first tech was here for 10 minutes and I was charged $200 just for him to turn the air off so it can defrost and then an additional $300 to come out the next day for 30 minutes. After further research with other companies I could’ve saved money for something so simple as HVAC refrigerant needed. They were recommended by my housing developers but I would never use them again. $500 in two days for less than a hour of service overall is absurd. Wish this company the best.
