YSA was very professional in help me with a DIY install of a new liwneset, evaporator and condenser. I needed brazing, leak test, and vacuum after I setup the new AC system. YSA listen to what I needed and completed the work integrity. He informed me the new condencer comes with R32 frigerant and I may needed a one pound. His price for the job was good and a lot less than what some of these clowns wanted to charge.

Very prompt service. They were able to diagnose my AC drain condensate problem and provided a solution that avoided a much larger job. Reasonable cost considering the ease of the fix. They were in and out with problems resolved within an hour and a half. Highly recommended!!!
