Highly recommend. My 22 year old AC was not cooling on the hot August long weekend.Called One Stop technician and arranged a time to come by and diagnose.The problem turned out that all the R22 refrigerant had leaked out and as R22 is hard to obtain and expensive we opted for a new system. The tech went out of his way to obtain the new unit and it was installed on Tues the day after the long weekend. Very impressed with the tech and the service.

Anton from One Stop, was pleasant, professional and very knowledgeable. He was honest about the fact that a AC would not be able to fit my house because other companies were trying to sell me over power A/C 3 ton but I needed 1.5 ton; other companies would have done the job in a slovenly manner just to make money. He installed new unit for my house and let me know exactly what he was doing during the process. One Stop HVAC is an trustworthy and professional company that I will definitely be using again.
