Midsouth Installers Heating & Cooling have been taking care of repairs and maintenance on my unit for a couple of years now and they have been just outstanding. My original unit broke down two years ago and they came in and installed a new one right away. Since then they have just been awesome. Their technicians are professional and polite when they're on the job. It's pretty easy to schedule with them and they call if they're going to be late or anything. They're just really good people and I'll certainly continue to use them.
