Oscar does a thorough job of inspecting everything and fixing anything that is not operating at 100%. Repair prices are a little expensive but it is reassuring to know that it is being fixed correctly and that I shouldn't have any problems in the future. In the past, I've had other companies that didn't know what they were doing and would have to call them back a month or two after an inspection to repair something that they should have spotted the first time they were out to visit.
