Mr. Chey Simpson did a great job by explaining how HVAC system works. He was very respectful, very knowledgeable and very experience. He inspected our components and showed me the values or numbers of where the ranges should be. You definitely want to keep your HVAC system operating properly or it can create other issues. He’s the first HVAC technician that explained to me what he was doing and why. I want to thank Garner for sending him out and thank Garner for their service. Great job. Oh and tell Doug hello from the Mendez family. (If you see him)
