They techs where very nice and polite but after I asked many times if maybe my duct work had holes or unhooked I was told defiantly not that my system was old and needed replaced. After a short you tube video and tested stuff myself found my blower fan not working up to par 200$ and fixed the duct work that was loose my ac is back and works great they charged me 300$+ would not recommend groggs as they just want to sell you a new unit for 10k plus they told me the fan would be close to a 1000$ to replace fan alone
