james H. west palm beach, florida April 21, 2021 "Semi-annual service was preformed. Told a part had to be replaced to correct a communication problem. I had paid $170 to correct the existing problem 2 months ago. Problem was never corrected. Asked the Technician to have company give me an estimate. Have not received estimate. Called company to talk to service manager, told I would receive call back. Two days later have not gotten a return call. Have purchased two A/C units from this company but will be looking for a new A/C company to do business in the future."
