We recently moved to an apartment and discovered a minor air conditioning issue. I had met Zac whilst he was on a service call at a restaurant my wife and I were at, so I called him hoping he could attend to our problem. Zac was able to fit us into his schedule the very next day! He called to keep me appraised of the time he would arrive, and was very prompt in coming. He reviewed our problem and concluded it was, indeed, a very minor issue which had actually resolved itself prior to his arrival. So, other than diagnosing that there was no issue, he performed no actual work. Despite my insisting I pay him for his time, Zac would not accept payment for the service call! That is genuine customer service! Throughout his time here he was very polite, professional and focused on the work to be done. I highly recommend Zac and Sunstate A/C & Heating.
