Not sure about this company. I bought my two ac units from Rose Refrigeration 3 years ago but understand R & R bought them out. Zee was very nice. Checked both units and said one of the units had ice buildup. He said the part was covered on warranty but we would have labor charges. (maintenance charge was $119.00) He took pictures but had to return to take more pictures as the first could not be viewed. Part was ordered. After part came in I was called and Zee came out. He was here about 40 minutes. Said he did not see anymore ice buildup and I told him the unit had been running fine. He said he thought we should go ahead and replace the broken valve. The bill was $582.00! Wow! This seems very expensive for something that may or may not have been needed. Don't know what to think. Ripoff or needed service??
