in the last weekWhen your AC goes out in Charleston, you’ve got a problem on your hands. Immediately called Chris Alexander. Now my biggest problem is that I’m freezing.

a week agoI was with a larger company that was not honest with me on a winter inspection for my HVAC unit, telling me I needed to replace things that didn’t need to be replaced. I was given the advice to go local and went with Chris and his company. Chris reassessed my situation and was honest and up front with me about the things the other company told me I need to replace, something that’s rare in a company today. I didn’t need any repairs and switched my business to Chris. Thanks Chris for being an honest, local businessman. We need more business's like yours..
