Over priced after doing my tune up on my 6 year old A/C unit, the tech told me that my unit was maybe 2 weeks of not working , that it needed a new motor, turbo capacitor, surge booster compressor. I should have done my research on how much these prices cost before agreeing to it but right when he left I looked for the price of turbo dual capacitor n cost around 30$ and they charged me 238$ for the part also the surge booster compressor they charged me 311$ which cost around 30$ as well plus another 179$ for the reserve club service. All in all I payed 787$ when all I wanted was the Cooling tune up. But the tech used his pressure and scaring me about how my ac unit could give out in the next 10 days. Even though I told him that my unit was fairly new. Last time using way overpriced company. Please do your research 1st people and read the review before calling them and doing business.
