Before 4 yrs I have brought ace but it gave me warranty of 2 yrs before completing its 2 yrs it made me to be reperence of 10000 thousand . When I call customer service it did not give me a good response .Its condenser is very bad because it need a repair in 5 months. I think that this company is too much worse. Its remote ia too much slow that when I set a timer of 2 hours it get stop in 4 hrs. It is bad too awrose limit that it may cost me 6000 monthly of my minimum use.
