I never review companies like this because I don't ever feel "wow-ed" enough to do so! But Greg and his team are really that great. They are super responsive, show up on time, explain what's wrong, use photos and details and look for the most affordable solution to get your system back up and running asap. They are transparent and I never feel like they are trying to sell me something more that is needed. Not only do I call them for my personal HVAC needs but I'm a realtor and I send them/recommened them when there's any issue at the homes of my clients. Often Greg will personally talk me through the options and cost of things before beginning any work. 5 stars!

We gradually became very disappointed with our long-time AC service company over the last couple of years so when our AC decided to take some time off the other day, it seemed a good time to move on.<br><br>There were several on the internet that presented well and had many good comments. But I kept going back to Greg's. Tons of great comments, but there's something extra, something different there, too: Greg himself has years of experience and is knowledgeable and capable of delivering what one hopes for when hiring AC help, but there's also the sense that he loves his business and wants his clients to love it also.<br><br>To that end, the tech (Isaac, I think) could not have done more. Communicated arrival time and actually arrived even a bit sooner, showed great interest and intention of solving the problem, for starters. He was very thorough in evaluating the issue and meticulous in satisfying himself that the AC was working perfectly when done.<br><br>In addition, I also appreciate the ease of contacting, the great communication, the time windows and the flat rates.

OUTSTANDING!<br>Our A/C stopped working, and the company we used to use in San Marcos is no longer reliable, the old man that used to be there isn't there anymore.<br><br>So we called Greg's and they are fantastic. All they had to do was blow the clog out, but they did more than that. They tested it numerous times and found that the loop of the drainage wasn't good so they adjusted what the previous company had done and made it better. And there was no charge for doing that.<br><br>Do you want your A/C to work properly? Do you want real workers, rather than kids? Do you want a company that knows what they are doing? Do you want a company that cares about their customers? If you answer yes then I guarantee that Greg's Heating and Air is for you. Aside from that, they have flat rates.
